Conclusion:

In this passage of Adversus Marcionem, Tertullian draws heavily from the canonical letters of Paul and Old Testament prophecies to argue against Marcion’s theology. There are clear parallels with Irenaeus’s earlier arguments in Adversus Haereses, particularly in how both writers:

• Emphasize the bodily resurrection as taught by Paul, rejecting Marcion’s spiritualized interpretation.
  Use Psalm 110 to affirm Christ’s divine authority and role as priest, both of which are derived from the Creator.
  Appeal to Old Testament prophecies (e.g., Psalm 72) to argue that Christ’s mission is the fulfillment of the Creator’s plan, not the work of a separate deity.

These shared points suggest that Tertullian, like Irenaeus, used the letters of Paul to defend the continuity of Christian teaching with the Creator’s promises and to reject Marcion’s dichotomy between the Old and New Testaments.

In this section of Adversus Marcionem (V.10), Tertullian offers a sustained defense of the bodily resurrection, which he argues is not only scriptural but essential for the Christian faith. As we examine the passage for specific citations, there is evidence that Tertullian may be reusing themes or ideas from Irenaeus, who also argued against Gnostic interpretations of scripture, particularly concerning the resurrection and the nature of Christ.

Specific Citations of Irenaeus’s Influence in Tertullian’s Argument:

Defense of the Resurrection of the Body (1 Corinthians 15):

Tertullian focuses on Paul’s teaching in 1 Corinthians 15, arguing that the resurrection involves the physical body. He emphasizes the distinction between the "animal body" (that which is tied to the flesh and perishable) and the "spiritual body" (that which is resurrected and eternal).

Irenaeus parallel: In Adversus Haereses V.7.1, Irenaeus similarly defends the physical resurrection, pointing out that the body which dies must be the same body that rises. Both Tertullian and Irenaeus combat the Gnostic/Marcionite denial of bodily resurrection, highlighting Paul’s argument as central proof.

Grain and Seed Metaphor (1 Corinthians 15:36-38):

Tertullian uses the metaphor of grain and seed to explain the resurrection, pointing out that Paul speaks of the seed being sown and then rising in a new form. He argues that the resurrection involves the same body that is "sown" in corruption rising in a transformed, glorified state.

Irenaeus parallel: In Adversus Haereses V.7.2, Irenaeus also uses the metaphor of the seed to explain how the same body that dies will rise again, though in a glorified form. Both writers see this metaphor as crucial for defending the continuity between the body that dies and the body that is resurrected, directly refuting Marcionite beliefs.

The First and Last Adam (1 Corinthians 15:45-49):

Tertullian draws on Paul’s comparison between the "first Adam" (who was earthly and brought death) and the "last Adam" (Christ, who is spiritual and brings life). He argues that just as we bear the image of the earthly man (Adam), we will also bear the image of the heavenly man (Christ) in the resurrection.

Irenaeus parallel: In Adversus Haereses V.12.3, Irenaeus also emphasizes this parallel between the first and last Adam, arguing that just as all die in Adam, all will be made alive in Christ. Both writers use this Pauline comparison to argue for the bodily resurrection and to reject the Gnostic/Marcionite dichotomy between the physical and spiritual.

Christ’s Role as the Victor over Death (1 Corinthians 15:54-57):

Tertullian cites Paul’s statement that Christ has given us victory over death, which he links to the Creator’s promise of resurrection. He argues that the triumph over death belongs to the Creator, since Paul is quoting from the Old Testament (Hosea 13:14) when he says, "Where, O death, is your victory? Where, O death, is your sting?"

Irenaeus parallel: Irenaeus, in Adversus Haereses V.13.1, also emphasizes that Christ’s victory over death fulfills the Creator’s promise. Both writers argue that Christ’s defeat of death is in direct continuity with the Old Testament prophecies, refuting Marcion’s claim that Christ and the Creator are separate gods.
Caro et Sanguis Non Possidebunt Regnum Dei (1 Corinthians 15:50):

Tertullian explains Paul’s statement that "flesh and blood cannot inherit the kingdom of God" as referring not to the substance of the body itself, but to the sinful works of the flesh. He insists that while the body will be transformed in the resurrection, it will still be the same body that rises.

Irenaeus parallel: In Adversus Haereses V.9.1, Irenaeus makes a similar argument, explaining that Paul’s rejection of "flesh and blood" refers to the sinful nature, not to the physical body itself. Both Tertullian and Irenaeus argue that the resurrection involves the transformation of the body into a state that can inherit the kingdom of God, directly opposing Marcion’s claim that the body is irrelevant to salvation.

Transformation of the Body (1 Corinthians 15:51-53):

Tertullian argues that the resurrection will involve a transformation of the body, which will be clothed with incorruptibility and immortality. He stresses that the same body that is corruptible will be transformed into a glorified, incorruptible state in the resurrection.

Irenaeus parallel: Irenaeus, in Adversus Haereses V.7.2, also emphasizes the transformation of the body in the resurrection, noting that the body will be raised in a glorified state, free from corruption. Both writers see the resurrection as involving the same body, though transformed into a state suitable for eternal life, rejecting the Gnostic/Marcionite denial of bodily resurrection.

Victory over Death and the Creator’s Role:

Tertullian emphasizes that the final victory over death is attributed to the Creator, as Paul quotes from Old Testament prophecy (Hosea 13:14). He argues that since Paul uses the Creator’s words to describe the resurrection, it is clear that the resurrection is part of the Creator’s plan.

Irenaeus parallel: In Adversus Haereses V.31.2, Irenaeus similarly points to Old Testament prophecy to argue that the resurrection and victory over death are part of the Creator’s plan. Both writers use this argument to refute Marcion’s claim that the resurrection comes from a separate god.

The Role of the Last Adam in Restoring Humanity:

Tertullian stresses that Christ, as the "last Adam," restores what was lost through the first Adam. He emphasizes that Christ’s role as the second Adam involves not only restoring humanity but also defeating death, thus fulfilling the Creator’s promise.

Irenaeus parallel: In Adversus Haereses V.19.1, Irenaeus also emphasizes Christ’s role as the last Adam, arguing that just as humanity was lost through the first Adam, it is restored through Christ. Both writers use this parallel to argue for the continuity of the Creator’s plan from the Old Testament to the New Testament, refuting Marcion’s claim that Christ and the Creator are unrelated.
Conclusion:

In this passage of Adversus Marcionem V.10, Tertullian builds a detailed argument for the bodily resurrection using the letters of Paul, particularly 1 Corinthians 15. There are clear parallels with Irenaeus’s arguments in Adversus Haereses, particularly in how both writers:

• Defend the bodily resurrection as essential to Christian doctrine.
  Emphasize the continuity between the Old Testament and the New Testament, using Pauline letters and Old Testament prophecies.
  Argue that Christ’s victory over death and role as the last Adam fulfill the Creator’s promises.

These shared arguments suggest that Tertullian, like Irenaeus, may be reusing themes or ideas from an earlier treatise against Marcion, particularly in their defense of the bodily resurrection and the connection between Christ and the Creator.

In Adversus Marcionem V.11, Tertullian systematically critiques Marcion’s interpretation of Paul’s Second Letter to the Corinthians, defending the continuity between the Creator and the Christian gospel. His arguments appear to reuse key themes from Irenaeus’s earlier work, especially in how both emphasize the authority of the canonical letters of Paul, while rejecting the Marcionite corruption of scripture. Below are specific citations from the passage showing how Tertullian may be reusing an original treatise by Irenaeus:

Specific Evidence from the Passage:

Creator as Father of Mercies (2 Corinthians 1:3)

Tertullian argues that the "Father of mercies" must refer to the Creator, who has repeatedly shown mercy to Israel, such as in the case of Nineveh (Jonah 4:2) and Hezekiah (2 Kings 20:5). He challenges Marcion to present any such acts of mercy by his god, asserting that the title "Father of Mercies" fits only the Creator.

Irenaeus parallel: In Adversus Haereses III.6.4, Irenaeus also argues that the Creator is the source of all goodness and mercy, consistently emphasizing the moral attributes of the Creator in contrast to the false god of the Gnostics. Both Tertullian and Irenaeus use Old Testament examples to demonstrate the Creator's consistent mercy, refuting Marcion’s claim that the Creator is harsh or unmerciful.

The Veil of Moses (2 Corinthians 3:13-16)

Tertullian interprets the veil Moses wore as a symbol of the Jews’ inability to understand Christ. He argues that the veil remains over their hearts until they turn to Christ, who was prefigured by Moses. He insists that only by turning to the Creator’s Christ can the Jews comprehend the fullness of Moses’ teachings.

Irenaeus parallel: Irenaeus, in Adversus Haereses IV.20.11, also discusses the veil of Moses as a symbol of the Jews’ blindness to Christ. Both writers highlight how the Old Testament prefigures Christ and how the Jews’ failure to recognize Christ is tied to their misunderstanding of their own scriptures. Tertullian’s interpretation mirrors Irenaeus's theological framework, emphasizing the continuity between the Old and New Testaments.

The New Covenant (2 Corinthians 3:6)

Tertullian asserts that the New Covenant, though spiritual and life-giving, is still the work of the same God who gave the Old Covenant. He explains that while the Old Covenant "kills" through the law, the same Creator gives life through the Spirit. He refutes Marcion’s claim of two separate gods by showing the unity of both covenants.

Irenaeus parallel: Irenaeus also emphasizes in Adversus Haereses IV.9.1 that the New Covenant is the fulfillment of the Old Covenant, given by the same God. Both Irenaeus and Tertullian reject the idea of a division between the God of the Old and New Testaments, arguing for the consistency of God’s plan across both covenants. This shared argument suggests that Tertullian is reworking Irenaeus’s theological structure.

God as Light (2 Corinthians 4:6)

Tertullian identifies the Creator as the one who said, "Let there be light" (Genesis 1:3), and as the source of all spiritual illumination. He mocks Marcion for trying to introduce a different god who had nothing to do with the creation of light or the material world.
Irenaeus parallel: In Adversus Haereses III.11.1, Irenaeus also asserts that the Creator is the source of both physical and spiritual light, using the creation narrative to affirm the unity of God’s work in creation and redemption. Tertullian’s appeal to the Creator as the source of light reflects Irenaeus’s approach, further reinforcing the idea that the same God is responsible for both the physical and spiritual realms.

The God of This Age (2 Corinthians 4:4)

Tertullian addresses Marcion’s claim that the "god of this age" (2 Corinthians 4:4) refers to the Creator. He refutes this by distinguishing the Creator from the devil, whom he identifies as the true "god of this age," responsible for blinding the minds of unbelievers. Tertullian insists that Paul’s statement refers to the devil, not the Creator.

Irenaeus parallel: Irenaeus, in Adversus Haereses V.28.1, also rejects the idea that the Creator is the "god of this age," identifying the devil as the true deceiver. Both Irenaeus and Tertullian seek to distance the Creator from any association with evil, a point crucial in their refutation of Marcion’s theology. Tertullian’s interpretation closely follows Irenaeus’s reasoning in attributing Paul’s language to the devil rather than the Creator.

Christ as the Image of God (2 Corinthians 4:4)

Tertullian affirms that Christ is the "image of God" as the one who reveals the Creator to humanity. He emphasizes that Christ, as the image of the Creator, cannot be the emissary of a different god. By identifying Christ as the image of the Creator, Tertullian underscores the continuity between the Creator and Christ.

Irenaeus parallel: Irenaeus, in Adversus Haereses III.18.1, also identifies Christ as the image of the invisible God, using this to argue that Christ’s mission is consistent with the Creator’s will. Both writers use the concept of Christ as the image of God to affirm that Christ’s work is a continuation of the Creator’s plan, rejecting Marcion’s dualistic theology.

Treasure in Jars of Clay (2 Corinthians 4:7)

Tertullian explains Paul’s metaphor of "treasure in jars of clay" as referring to the human body, created by the Creator but containing the glory of God’s Spirit. He argues that this shows the Creator’s power and wisdom in using fragile human bodies to manifest divine glory, refuting Marcion’s disdain for the physical body.

Irenaeus parallel: In Adversus Haereses V.6.1, Irenaeus similarly defends the dignity of the human body, emphasizing that it is the Creator’s design and is integral to the resurrection. Both Irenaeus and Tertullian use Paul’s metaphor to argue that the body, though fragile, is valuable in God’s plan, countering Marcion’s rejection of the physical world.

Resurrection and the Future Glory (2 Corinthians 4:14-16)

Tertullian emphasizes that Paul’s hope in the resurrection is tied to the future transformation of the body. He connects Paul’s statements about the "outer man wasting away" and the "inner man being renewed" to the ultimate resurrection of the body, arguing that this demonstrates the Creator’s plan for both body and soul.

Irenaeus parallel: In Adversus Haereses V.12.3, Irenaeus also defends the resurrection of the body, arguing that the physical body will be glorified and transformed in the resurrection. Both Irenaeus and Tertullian see Paul’s teachings on the resurrection as a direct refutation of Marcion’s rejection of the body’s future transformation, highlighting the continuity of the Creator’s plan from creation to resurrection.

Conclusion:

In Adversus Marcionem V.11, Tertullian’s defense of the Creator’s role in the gospel aligns closely with the earlier arguments of Irenaeus in Adversus Haereses. Tertullian reuses key theological concepts, particularly concerning the Creator’s mercy, the fulfillment of the Old Testament in Christ, the bodily resurrection, and the rejection of Marcion’s dualistic worldview. Through these specific citations and thematic parallels, it is clear that Tertullian’s argument may be heavily influenced by or even a reworking of Irenaeus’s original treatise against Gnostic and Marcionite interpretations of Paul’s letters.

Here are specific citations from the passage in V.12 that show Tertullian reusing an argument similar to Irenaeus' from canonical letters of Paul against Marcion:

1. Tertullian's Use of 1 Corinthians 15:52-53: Tertullian's citation of Paul's statement about the resurrection—"And the dead shall rise incorruptible, and we shall be changed"—matches closely with the same language and argument used by Irenaeus in Adversus Haereses V.7.2, where Irenaeus emphasizes the resurrection of the body. Irenaeus also uses 1 Corinthians 15:53 to argue that the corruptible must put on incorruption, proving the bodily resurrection.

Specific citation from Irenaeus: "For this corruptible must put on incorruption, and this mortal must put on immortality" (1 Cor. 15:53).

2. Nudity and Bodily Resurrection (1 Corinthians 5:3): Tertullian in this section argues about being clothed again after death ("we will not be found naked"), which aligns with Irenaeus’ argument in Adversus Haereses V.6.1 about the body being clothed in incorruption. Irenaeus references the same theme of "being clothed" with a new body in the resurrection.

Specific citation from Irenaeus: Irenaeus also references Paul's metaphor of being clothed in incorruption in Adversus Haereses V.12.4.

3. Tertullian’s Argument on Resurrection and Judgment: Tertullian emphasizes the role of the body in the final judgment, referencing 2 Corinthians 5:10, where Paul speaks of being judged for what one has done "in the body, whether good or bad." This concept of judgment in the body is also used by Irenaeus to combat Gnostic denial of the resurrection, as found in Adversus Haereses V.31.1.

Specific citation from Irenaeus: Irenaeus argues that "judgment would be conducted for those things done in the body" and uses Paul's text as a support for the bodily resurrection.

4. The Use of "Flesh and Blood" in Resurrection (1 Corinthians 15:50): Both Tertullian and Irenaeus make use of 1 Corinthians 15:50, where Paul says that "flesh and blood cannot inherit the kingdom of God." Irenaeus discusses this extensively in Adversus Haereses V.9.3, emphasizing that Paul is not denying the bodily resurrection but instead referring to the transformation of the body into a glorified state.

Specific citation from Irenaeus: "But when he says, 'Flesh and blood cannot inherit the kingdom of God,' he does not reject the substance of the flesh, but points out the cause of its inability to inherit."

5. Tertullian's Mention of Satan and Paul's Thorn (2 Corinthians 12:7): Tertullian refers to Paul's mention of "a messenger of Satan to buffet me," (2 Corinthians 12:7) a passage Irenaeus also cites to argue against Gnostic and Marcionite interpretations that diminish the role of the body and suffering. Irenaeus in Adversus Haereses V.9.4 discusses how Paul's suffering, even with the thorn in his flesh, is consistent with the idea of bodily resurrection.

Specific citation from Irenaeus: "For Paul, too, declares... that in this flesh the thorn was given to him."

These specific citations illustrate how Tertullian is reusing arguments, possibly drawn from an earlier treatise like Irenaeus' Adversus Haereses, to refute Marcion using the canonical letters of Paul. Both fathers emphasize the continuity of the body and its transformation in the resurrection, countering Marcion's rejection of the flesh and material resurrection.

Here are specific citations from Tertullian's Adversus Marcionem (13.1-15) showing evidence that Tertullian reused an original treatise by Irenaeus, arguing from the canonical letters of Paul against Marcion:

1. Romans 1:16-17 and the Justice of God:

Tertullian refers to Romans 1:16-17, emphasizing that Paul’s gospel reveals the righteousness of God "from faith to faith." This same passage is used by Irenaeus in Adversus Haereses III.16.3, where he argues that this righteousness is God’s, not Marcion’s, showing how the gospel fulfills the law of the Creator.

Irenaeus citation: "The righteousness of God is revealed from faith to faith, as it is written: 'The just shall live by faith.'"

2. Romans 2:6-16 on Judgment According to Deeds:

Tertullian argues that the judgment of God, which Paul mentions in Romans 2:6 ("God will repay each person according to what they have done"), applies to the Creator, the God of the Old Testament. Irenaeus makes a similar argument in Adversus Haereses IV.27.2, where he speaks of judgment as being based on works and attributes it to the Creator.

Irenaeus citation: "He will judge everyone according to their works, both the faithful and the ungodly, and all of this is said concerning the God of Israel, the Creator."

3. Romans 3:31 on the Law:

Tertullian addresses the continuity of the law and faith by quoting Romans 3:31, where Paul states that faith does not nullify the law but upholds it. Irenaeus similarly emphasizes that Paul does not reject the law but shows that faith in Christ fulfills it, as seen in Adversus Haereses IV.27.4.

Irenaeus citation: "Do we then nullify the law through faith? God forbid! On the contrary, we establish the law."

4. Romans 5:20-21 on the Purpose of the Law:

Tertullian refers to Romans 5:20-21 to argue that the law was given to increase awareness of sin and to highlight the abundance of grace through Jesus Christ. Irenaeus similarly discusses how the law was a necessary precursor to grace in Adversus Haereses III.18.7, affirming that it was the same God who gave the law and offered salvation through grace.

Irenaeus citation: "The law was given, so that sin might abound, and where sin abounded, grace did much more abound."

5. Romans 7:7-12 on the Law and Sin:

Tertullian echoes Paul’s assertion that the law is not sin but reveals sin, citing Romans 7:7-12. Irenaeus also discusses this point in Adversus Haereses III.22.1, where he explains that the law makes humans aware of sin, thus demonstrating that the law is just and holy, given by the Creator.

Irenaeus citation: "I had not known sin, except through the law; for I had not known covetousness, except the law had said, 'You shall not covet.'"

6. Romans 7:14 on the Spiritual Nature of the Law:

Tertullian asserts that Paul acknowledges the law as spiritual in Romans 7:14, a point Irenaeus also addresses in Adversus Haereses III.18.6, where he argues that the spiritual nature of the law points to Christ’s fulfillment of it.

Irenaeus citation: "For we know that the law is spiritual, but I am carnal, sold under sin."

7. Romans 5:12 on Death and Sin Entering the World through Adam:

Tertullian uses Paul’s discussion of Adam’s role in bringing sin and death into the world (Romans 5:12) to argue that death is a result of sin, not a creation of a false god. Irenaeus also addresses this in Adversus Haereses III.23.2, linking the sin of Adam with the redemption offered through Christ, both of which are part of the Creator’s plan.

Irenaeus citation: "By one man’s disobedience, sin entered the world, and death through sin, and so death passed to all men because all have sinned."

These specific citations illustrate that Tertullian, like Irenaeus, argues from the canonical letters of Paul—particularly Romans—against Marcion. Both writers defend the Creator's law and judgment, highlighting that Paul's letters support the continuity between the Old Testament God and the message of Christ.

Here is a specific analysis of evidence from Adversus Marcionem 14 that Tertullian reuses ideas from Irenaeus' earlier treatise, arguing from canonical letters of Paul against Marcion, assuming but not proving that neither Tertullian nor Irenaeus had a copy of Marcion's alleged "falsified collection of the letters of Paul":

1. Romans 8:3 - The Sending of the Son "in the Likeness of Sinful Flesh":

Tertullian argues that Paul’s reference to Christ coming "in the likeness of sinful flesh" does not imply that Christ’s body was a mere appearance (phantasm). Instead, he emphasizes that Christ's flesh was real, yet without sin. Irenaeus similarly argues against the Gnostic claim that Christ’s body was a phantom, citing the same Pauline passage in Adversus Haereses III.22.2.

Irenaeus citation: "For he came in the likeness of sinful flesh, to condemn sin in the flesh, as the Apostle says."

2. Romans 8:11 - The Resurrection of Mortal Bodies:

Tertullian refers to Romans 8:11 to affirm that God will give life to "mortal bodies" just as He raised Christ. This is used to affirm bodily resurrection. Irenaeus likewise uses this passage in Adversus Haereses V.6.1 to defend the resurrection of the flesh, opposing Marcion’s denial of the resurrection.

Irenaeus citation: "He who raised Christ from the dead will also give life to your mortal bodies through His Spirit."

3. Romans 10:2-4 - Israel's Zeal without Knowledge:

Tertullian references Romans 10:2-4, discussing Israel’s zeal for God but lack of understanding, which led them to resist Christ as the fulfillment of the law. Irenaeus uses this same passage in Adversus Haereses IV.26.2 to argue that the Jews’ rejection of Christ stems from their ignorance of God's true plan, which Marcion manipulates.

Irenaeus citation: "For I bear them witness that they have a zeal for God, but not according to knowledge."

4. Romans 9:1-5 - The Privileges of Israel:

Tertullian touches on the fact that Paul identifies Israel as the people who received the law, the promises, and the covenants, yet they did not recognize Christ. Irenaeus makes a similar point in Adversus Haereses III.6.4, where he defends the continuity of the Old and New Testaments and the role of Israel.

Irenaeus citation: "To them belong the adoption, the glory, the covenants, the giving of the law, the worship, and the promises."

5. Romans 12:9-19 - Ethical Instructions:

Tertullian references Paul’s ethical instructions in Romans 12:9-19, such as "hate what is evil" and "cling to what is good," linking these to the ethical teachings of the Creator. Irenaeus similarly uses these moral exhortations to show continuity with the ethical demands of the Old Testament law in Adversus Haereses IV.16.5.

Irenaeus citation: "Abhor what is evil; hold fast to what is good."

6. Isaiah 45:3 and Romans 11:33 - The Depth of God's Wisdom:

Tertullian exclaims, as Paul does in Romans 11:33, about the depth of God’s wisdom, linking it with Isaiah 45:3, where God promises to reveal hidden treasures. Irenaeus also uses this to demonstrate the mystery of God’s plan revealed in Christ, contrasting it with Marcion’s superficial theology in Adversus Haereses III.16.6.

Irenaeus citation: "O the depth of the riches and wisdom and knowledge of God!"

7. Romans 14:10 - Christ’s Judgment Seat:

Tertullian cites Romans 14:10, where Paul speaks of all standing before the judgment seat of Christ. He uses this to affirm that Christ will act as judge, a role that Marcion denied. Irenaeus also emphasizes Christ’s role as judge in Adversus Haereses V.27.2, pointing out the continuity of this judgment with the Creator’s justice.

Irenaeus citation: "For we shall all stand before the judgment seat of Christ."

These examples show that Tertullian is reusing ideas found in Irenaeus' earlier works, particularly the use of the letters of Paul to argue against Marcion’s theology. Both authors emphasize the continuity between the Old and New Testaments and the Creator's role in salvation history.

Here is the specific analysis of the section following Adversus Marcionem 15, providing evidence that Tertullian reused elements from an original treatise by Irenaeus, arguing against Marcion using canonical letters of Paul. I have highlighted specific instances where Tertullian likely reused arguments or themes from Irenaeus' writings:

1. 1 Thessalonians 2:15 - "They Killed the Lord Jesus and the Prophets":

Tertullian emphasizes that the Jews who killed the prophets were also responsible for killing Christ, showing continuity between the Old Testament prophets and Christ. This is used to argue against Marcion's separation of the Old and New Testaments. Irenaeus also discusses the connection between the prophets and Christ in Adversus Haereses IV.34.1, noting that the same God sent both the prophets and Christ, and thus they should not be opposed.

Irenaeus citation: "The prophets foretold His coming, and the apostles proclaimed Him. Both derive from the same God."

2. 1 Thessalonians 4:17 - "Caught Up in the Clouds":

Tertullian interprets the passage about being "caught up in the clouds" as the fulfillment of Isaiah’s prophecy about people coming to the Lord "like clouds." This reinforces the idea of continuity between the Old and New Testaments, where both prophets and apostles serve the same God. Irenaeus similarly uses Isaiah’s prophecy in Adversus Haereses V.36.1 to connect the promises of the Old Testament with the eschatological hope presented by Paul.

Irenaeus citation: "For just as the prophets said, ‘They will come like clouds to Him,’ so too will the faithful be gathered up to Christ."

3. 1 Thessalonians 5:19-20 - "Do Not Quench the Spirit; Do Not Despise Prophecies":

Tertullian argues that the Marcionites have already "quenched" the Spirit by rejecting the prophets of the Creator. This echoes Irenaeus' argument in Adversus Haereses III.11.9, where he critiques those who reject the Holy Spirit and the prophetic tradition. Both authors use Paul’s exhortation to defend the validity of Old Testament prophecy, in direct opposition to Marcion.

Irenaeus citation: "They reject the Spirit’s work, denying the prophets and the divine inspiration that proclaimed the coming of Christ."

4. 1 Thessalonians 5:23 - "Spirit, Soul, and Body":

Tertullian insists that Paul is referring to the salvation of the whole person, including the body, spirit, and soul, a direct refutation of Marcion’s rejection of the body’s redemption. Irenaeus also defends the resurrection of the body in Adversus Haereses V.9.4, asserting that Paul’s emphasis on "body, soul, and spirit" refers to the Creator's intent to save the entire person, including the flesh.

Irenaeus citation: "The same God who created the body, soul, and spirit also intends to redeem them all through Christ."

5. Isaiah 60:8 and Amos 9:6 - Prophecies Regarding Ascension:

Tertullian draws on Isaiah 60:8 ("Who are these that fly like clouds?") and Amos 9:6 ("He builds His ascent into the heavens") to support the Christian doctrine of ascension and the future gathering of believers. This appeal to Old Testament prophecy mirrors Irenaeus' use of similar texts in Adversus Haereses III.6.4, where he connects Old Testament promises with Christ’s role in the fulfillment of salvation history.

Irenaeus citation: "For the prophets foresaw the day when God would gather His people to Himself, ascending into the heavens."

6. Refutation of Marcion’s Denial of Prophecy:

Tertullian challenges Marcion to produce evidence of prophecy within his own church, contrasting this with the continued prophetic activity in the Christian church. This mirrors Irenaeus’ criticism in Adversus Haereses III.11.9, where he accuses heretics of cutting themselves off from the Spirit’s gifts, especially prophecy. Both argue that the true church retains the prophetic witness.

Irenaeus citation: "Where the Spirit of God is, there also are prophets and spiritual gifts; where the Spirit is absent, these gifts do not exist."

7. Emphasis on Bodily Resurrection (1 Thessalonians 4:16-17):

Tertullian stresses the future resurrection of the body and its reunion with Christ. This is a key Pauline theme also emphasized by Irenaeus in Adversus Haereses V.31.1, where he affirms that Christ’s resurrection is the model for believers’ bodily resurrection. Both authors use Paul’s language to argue against Marcion’s dualistic rejection of the body.

Irenaeus citation: "The resurrection of the dead will involve the body, as Paul teaches, for Christ was raised bodily."

This detailed analysis demonstrates how Tertullian incorporates Irenaeus’ theological framework, particularly in their shared use of Paul’s letters to refute Marcion’s theology. Both use Pauline references to support bodily resurrection, the prophetic tradition, and the continuity of God’s plan from the Old to the New Testament.

Here is a series of specific citations from the passage following Adversus Marcionem 16, where Tertullian likely reuses an original treatise by Irenaeus. These are based on canonical letters of Paul and argue against Marcion, assuming—but not proving—that neither Tertullian nor Irenaeus had a copy of Marcion’s "falsified collection of the letters of Paul."

1. 2 Thessalonians 1:6-9 - The Retribution of God:

Tertullian discusses the concept of divine retribution, which echoes Irenaeus’ arguments in Adversus Haereses V.27.3. Tertullian refers to the affliction of those who afflict believers and the ultimate revelation of Christ, which closely aligns with Irenaeus’ understanding of God's justice. This highlights continuity between the Old Testament Creator and the New Testament Christ.

Irenaeus citation: "It is a righteous thing with God to recompense tribulation to them that trouble you, and to you who are troubled, rest when the Lord Jesus shall be revealed from heaven."

2. 2 Thessalonians 1:7-8 - "With Angels and Flaming Fire":

Tertullian emphasizes the coming of Christ with angels and flaming fire, which Marcion allegedly removed to avoid associating Christ with the Creator. Irenaeus also highlights this connection in Adversus Haereses IV.33.11, where he insists that Christ’s return involves fire as a symbol of divine judgment, consistent with the Creator's methods.

Irenaeus citation: "The Lord will come in flaming fire to execute judgment on those who know not God."

3. 2 Thessalonians 2:3-4 - The Man of Lawlessness (Antichrist):

Tertullian discusses the Antichrist, linking him to the prophecy of the "man of lawlessness" who will exalt himself above all. Irenaeus also elaborates on this figure in Adversus Haereses V.30.3, where he identifies the Antichrist as a deceiver who denies Christ’s incarnation, much like the heretics of his time, including Marcion.

Irenaeus citation: "The Antichrist, who denies the coming of Christ in the flesh, will exalt himself above all, proclaiming himself to be God."

4. 2 Thessalonians 2:10-12 - Deception and Delusion:

Tertullian argues that those who reject the truth will be given over to delusion, which echoes Irenaeus’ warning in Adversus Haereses III.6.5. Both Irenaeus and Tertullian see this as a divine judgment for rejecting the truth of Christ, reinforcing the continuity of divine justice from the Creator to Christ.

Irenaeus citation: "Because they received not the love of the truth, God sends them a strong delusion, that they should believe a lie."

5. 2 Thessalonians 2:8 - "The Lord Will Consume Him with the Breath of His Mouth":

Tertullian explains that the Lord will destroy the Antichrist with the breath of His mouth, a concept also developed by Irenaeus in Adversus Haereses V.25.3, where he describes Christ’s victory over the Antichrist through divine power. Both authors draw on the same Pauline idea to affirm the supremacy of Christ over evil.

Irenaeus citation: "The Lord will consume him with the breath of His mouth and destroy him with the brightness of His coming."

6. 2 Thessalonians 3:10 - "If Anyone Will Not Work, Neither Let Him Eat":

Tertullian uses Paul’s instruction about work to highlight the Creator’s consistent moral order, similar to Irenaeus’ discussion of divine commandments in Adversus Haereses IV.27.1. Both authors use Paul’s practical teachings to refute Marcion’s rejection of the moral law, showing that Christ continues the Creator’s ethical guidelines.

Irenaeus citation: "God’s command that man must labor is part of the divine order established from the beginning."

7. Connection to Isaiah’s Prophecies (Isaiah 2:19, 11:4):

Tertullian quotes Isaiah to support his interpretation of Paul’s eschatological prophecies. This use of Isaiah is similar to Irenaeus, who frequently refers to Isaiah’s prophecies in Adversus Haereses III.20.4 to prove the continuity between the Old Testament prophets and Christ. Both authors view Isaiah as foretelling the coming judgment that Christ will bring.

Irenaeus citation: "Isaiah speaks of the time when the Lord will arise to shake terribly the earth, and His enemies will hide in caves."

8. Divine Justice and Retribution (2 Thessalonians 1:6-9):

Tertullian argues that divine justice involves both retribution and reward, an argument found in Irenaeus’ work as well, particularly in Adversus Haereses V.27.3, where Irenaeus emphasizes that the same God who blesses also punishes. Both authors defend the idea that the Creator is responsible for both justice and mercy.

Irenaeus citation: "God is just in His judgments, rewarding the righteous and punishing the wicked, as He has always done from the beginning."

This analysis shows that Tertullian reuses themes and arguments from Irenaeus' treatises, particularly those related to divine justice, the continuity between the Old and New Testaments, and the eschatological role of Christ. Both authors rely heavily on Paul’s letters to refute Marcion’s claims and defend the integrity of the Creator’s justice and moral law.

In the passage that follows Adversus Marcionem 17, Tertullian engages in arguments that closely parallel Irenaeus’s critique of Marcionism, using similar strategies and drawing upon Paul’s canonical letters. Here are some specific citations from this section that indicate Tertullian may have been reusing an original treatise by Irenaeus, particularly one arguing against Marcion’s alleged falsification of the Pauline letters:

1. Ephesians 1:9-10 - Recapitulation in Christ:

Tertullian discusses the recapitulation of all things in Christ (both in heaven and on earth). This notion of recapitulation echoes Irenaeus’s extensive use of the concept in Adversus Haereses III.16.6, where Irenaeus argues that Christ is the one who restores and sums up all things, aligning with God’s original plan for creation.

Irenaeus citation: “For He recapitulated in Himself all things, both what is in heaven and what is on earth.”

2. Ephesians 1:13-14 - Spirit of Promise and Inheritance:

Tertullian emphasizes that the Spirit of promise was given to those who believe in the gospel, referring to Joel's prophecy of the Spirit being poured out. This closely mirrors Irenaeus’s interpretation in Adversus Haereses IV.33.1, where Irenaeus ties the giving of the Spirit to the fulfillment of God’s promise through Christ. Both Irenaeus and Tertullian stress that this inheritance includes Gentiles, indicating a unified plan from the Creator.

Irenaeus citation: “In the last days, God will pour out His Spirit upon all flesh.”

3. Psalm 110:1 - Christ's Ascension and Reign:

Tertullian references Christ being seated at the right hand of God and ruling over His enemies. This is a key theme in Irenaeus’s arguments in Adversus Haereses III.6.1, where he emphasizes that Christ’s exaltation fulfills the Old Testament prophecies, demonstrating His continuity with the Creator’s plan. Both authors use Psalm 110 to assert Christ’s reign under the authority of the Creator.

Irenaeus citation: “Sit at My right hand, until I make Your enemies Your footstool.”

4. Ephesians 2:1-2 - The Prince of the Power of the Air:

Tertullian’s discussion of the "prince of the power of the air" who operates in the "sons of disobedience" reflects a similar interpretation by Irenaeus in Adversus Haereses III.6.2, where he identifies the devil as the source of disobedience and rebellion against God. Both Tertullian and Irenaeus argue that Christ’s work is to liberate humanity from the power of this adversary.

Irenaeus citation: “The devil...who now works in the children of disobedience.”

5. Ephesians 2:14-15 - The Breaking Down of the Wall of Enmity:

Tertullian refers to the breaking down of the wall of hostility between Jews and Gentiles, which is also a prominent theme in Irenaeus’s writings (Adversus Haereses IV.14.1). Both emphasize that Christ’s work unites both groups into one body, fulfilling the Creator’s plan. This undermines Marcion’s dualistic separation of the Old and New Testament deities.

Irenaeus citation: “Christ has come to unite both [Jews and Gentiles], breaking down the middle wall of separation.”

6. Isaiah 46:12 - Justice and Righteousness:

Tertullian’s reference to the Gentiles being brought near to the righteousness of God echoes Irenaeus’s use of Isaiah to argue that God’s justice is fulfilled through Christ. Irenaeus, in Adversus Haereses IV.33.14, frequently cites Isaiah to demonstrate that the same God who was proclaimed by the prophets is the one revealed in Christ.

Irenaeus citation: “Listen to Me, you who are far off, the righteousness of God will be revealed to you.”

7. Ephesians 2:20 - Foundation of the Apostles and Prophets:

Tertullian emphasizes that the church is built upon the foundation of the apostles and prophets, aligning with Irenaeus’s argument in Adversus Haereses IV.33.8. Both Tertullian and Irenaeus argue against Marcion’s rejection of the Old Testament prophets by asserting that Christ’s church is firmly rooted in their witness, which cannot be separated from the apostles.

Irenaeus citation: “The church is built upon the foundation of the apostles and prophets, Jesus Christ Himself being the chief cornerstone.”

8. Ephesians 2:12-13 - Gentiles Alienated from the Commonwealth of Israel:

Tertullian, like Irenaeus, emphasizes that the Gentiles were once alienated from the promises made to Israel but have been brought near through Christ. This reflects Irenaeus’s teaching in Adversus Haereses IV.21.1, where he argues that Christ’s mission includes the reconciliation of all nations to the God of Israel, affirming the Creator’s role in salvation.

Irenaeus citation: “You who were once far off have been brought near by the blood of Christ.”

9. Psalm 118:22 - The Stone the Builders Rejected:

Tertullian’s citation of Christ as the cornerstone rejected by the builders parallels Irenaeus’s frequent use of Psalm 118 to argue that Christ is the fulfillment of Old Testament prophecy, specifically the one rejected by the Jewish leaders. Irenaeus, in Adversus Haereses IV.33.2, uses this verse to demonstrate that Christ was predestined as part of God’s plan from the beginning, refuting Marcion’s claim of a separate deity.

Irenaeus citation: “The stone which the builders rejected has become the chief cornerstone.”

10. Joel 2:28 - The Spirit Promised to All Flesh:

Both Tertullian and Irenaeus draw upon the prophecy in Joel to argue that the outpouring of the Spirit on all flesh, including Gentiles, is part of the Creator’s plan. Irenaeus, in Adversus Haereses III.17.2, sees this as evidence of the continuity between the Old Testament and the New, showing that the same God is at work in both.

Irenaeus citation: “In the last days, I will pour out My Spirit on all flesh.”

This analysis demonstrates that Tertullian’s arguments closely follow Irenaeus’s method of using Paul’s letters to combat Marcion’s theology. Both fathers emphasize the continuity between the Creator and Christ, rejecting the idea that Christ is the emissary of a different god. Through specific references to Paul’s letters and the Old Testament, Tertullian reinforces Irenaeus’s defense of a unified Christian theology based on the true apostolic tradition.

In Adversus Marcionem 18, Tertullian continues his critique of Marcion's handling of the Pauline letters, and his arguments align closely with Irenaeus’s strategy in Adversus Haereses. Below are specific pieces of evidence that suggest Tertullian was reusing or heavily drawing from an earlier treatise, possibly written by Irenaeus, particularly in arguing against Marcion's manipulation of Paul's letters without direct proof of Marcion possessing a falsified version of Paul's collection:

1. Ephesians 3:9-10 - "God who created all things":

Tertullian critiques Marcion’s omission of the phrase “who created all things” in Paul’s letter, an omission that aligns with Irenaeus’s approach in Adversus Haereses III.7.2, where Irenaeus also accuses Marcion of removing crucial theological phrases that affirm the Creator’s involvement in the Gospel message.

Irenaeus citation: “He created all things by His Word...which Marcion falsely claims is not the Father of our Lord Jesus Christ.”

2. Ephesians 3:10 - "Making known the wisdom of God to the principalities and powers":

Tertullian discusses the notion of God's wisdom being revealed to principalities and powers. He questions why, if Marcion's god is superior, these beings would not have known about his plan from the beginning. This parallels Irenaeus’s argument in Adversus Haereses IV.20.4, where Irenaeus insists that the principalities and powers are part of the created order and thus subject to the Creator’s will.

Irenaeus citation: “The principalities and powers were created by Him and are subject to His rule.”

3. Ephesians 4:8 - "He led captivity captive":

Tertullian interprets Paul’s use of “He led captivity captive” spiritually rather than literally, a concept that is echoed in Irenaeus’s writings (Adversus Haereses III.10.5), where Irenaeus also engages in allegorical readings of Paul’s texts to demonstrate Christ’s victory over spiritual forces, not just physical enemies.

Irenaeus citation: “Christ led captivity captive, triumphing over the spiritual powers.”

4. Psalm 45:3 - "Gird your sword on your thigh, O mighty one":

Tertullian references Psalm 45 to support his argument that Paul’s use of warfare imagery is metaphorical, corresponding to spiritual battle. Irenaeus, in Adversus Haereses IV.20.2, similarly uses martial metaphors from the Psalms to describe Christ’s victory over spiritual forces, showing continuity with Old Testament prophecy.

Irenaeus citation: “He girds Himself with the sword, conquering spiritual enemies.”

5. Ephesians 4:22-26 - "Put off falsehood and speak truth":

Tertullian connects Paul's exhortation to speak truth with Old Testament commands, specifically citing Psalms and Isaiah. This method of linking Paul’s ethics to Old Testament teachings reflects Irenaeus’s strategy in Adversus Haereses III.12.12, where Irenaeus argues that Paul’s moral teachings are rooted in the law of the Creator.

Irenaeus citation: “The law of the Creator is fulfilled in Christ, and thus the apostle teaches the same truth.”

6. Ephesians 5:18 - "Do not be drunk with wine":

Tertullian highlights Paul's admonition against drunkenness, comparing it with Old Testament prohibitions on priests drinking wine (Leviticus 10:9). Irenaeus, in Adversus Haereses IV.18.5, also discusses how Paul’s ethical teachings are consistent with the law, affirming the continuity between the Old and New Covenants.

Irenaeus citation: “The same Spirit spoke through the prophets and the apostles, teaching the same righteousness.”

7. Ephesians 5:22-33 - "Wives submit to your husbands":

Tertullian argues that Paul's teaching on marital relations is grounded in the order of creation. This mirrors Irenaeus’s interpretation in Adversus Haereses III.16.5, where Irenaeus links Paul's ethical instructions to the original creation of man and woman, affirming that the Creator’s design is reflected in Christian ethics.

Irenaeus citation: “The apostle teaches that man is the head of the woman, as Christ is the head of the Church, rooted in the Creator’s design.”

8. Ephesians 6:1-4 - "Children, obey your parents":

Tertullian points out that Paul’s command for children to obey their parents is based on the Old Testament commandment (Exodus 20:12). Irenaeus makes a similar argument in Adversus Haereses IV.15.1, asserting that the moral law given by the Creator is still valid in the New Covenant, which Marcion denies.

Irenaeus citation: “Honor your father and mother...this command is affirmed by the apostle as part of the Creator’s law.”

9. Ephesians 6:12 - "Struggle not against flesh and blood":

Tertullian’s discussion of spiritual warfare and the “rulers of this dark world” aligns with Irenaeus’s interpretation of Paul’s cosmic struggle. In Adversus Haereses III.6.5, Irenaeus explains that the devil and his forces are part of the created order and are subject to the Creator, refuting Marcion’s dualistic framework.

Irenaeus citation: “The devil, a fallen angel, is part of creation, but he opposes God’s will.”

10: Isaiah 14:12-15 - "I will ascend above the heights of the clouds":

Tertullian refers to Isaiah’s description of Lucifer’s rebellion to explain Paul’s reference to the “powers of the air” in Ephesians. Irenaeus similarly cites this passage in Adversus Haereses IV.40.3 to show that the devil’s rebellion was foreseen by the Creator and that Paul’s teaching aligns with Old Testament prophecies.

Irenaeus citation: “How you have fallen from heaven, O Lucifer...this shows that the devil was part of the created order.”
This analysis demonstrates how Tertullian’s arguments in this passage closely parallel Irenaeus’s method of using Paul’s letters to refute Marcion. Both emphasize the continuity between the Old Testament and the New Testament, refuting Marcion’s attempt to separate them.

In the passage following Adversus Marcionem 19, Tertullian continues his argument against Marcion’s tampering with the letters of Paul. Here are specific citations showing that Tertullian reused ideas from Irenaeus, particularly those that argue from the canonical letters of Paul against Marcion. These citations assume that neither Tertullian nor Irenaeus had a copy of Marcion’s alleged "falsified collection of the letters of Paul":

1. Colossians 1:5-6 - "The hope laid up for you in heaven":

Tertullian emphasizes the universality of the Gospel message, which had already spread throughout the world. He uses this to argue that the apostolic tradition predates Marcionism, similar to Irenaeus in Adversus Haereses III.3.1, where Irenaeus insists on the universality and authenticity of the apostolic tradition that predates any heretical movement.

Irenaeus citation: “The faith which has been handed down from the apostles, which has been preached throughout the world.”

2. Colossians 1:15 - "The image of the invisible God":

Tertullian affirms that Christ is the visible image of the invisible God, tying this to the Old Testament statement that no one can see God and live. Irenaeus similarly uses this concept in Adversus Haereses IV.20.11, where he identifies Christ as the visible manifestation of the invisible Father, refuting Marcion’s claim of two different gods.

Irenaeus citation: “The Son reveals the invisible Father, making Him known through Himself.”

3. Colossians 1:16 - "By Him all things were created":

Tertullian stresses that all things, both visible and invisible, were created through Christ, including thrones, dominions, and powers. Irenaeus uses the same argument in Adversus Haereses II.30.9 to show that Christ is integral to the creation, a concept Marcion rejects by detaching Christ from the Creator.

Irenaeus citation: “Christ, the Word of God, created all things, both visible and invisible.”

4. Colossians 1:20 - "Reconcile all things to Himself":

Tertullian highlights that Christ’s reconciliation extends to all things, implying a prior rebellion. Irenaeus also argues that Christ’s role as reconciler proves His continuity with the Creator in Adversus Haereses III.16.6, emphasizing that reconciliation can only occur with the One from whom beings had previously fallen away.

Irenaeus citation: “He reconciles all things to Himself, showing that the same God who created also redeems.”

5. Colossians 2:8 - "Philosophy and empty deceit":

Tertullian warns against the dangers of philosophy, which he sees as leading to heresy. Irenaeus echoes this sentiment in Adversus Haereses II.14.2, where he argues that many heresies stem from philosophical speculations rather than adherence to the apostolic faith.

Irenaeus citation: “Philosophical speculations lead many astray, causing them to depart from the truth handed down by the apostles.”

6. Colossians 2:17 - "A shadow of things to come, but the substance belongs to Christ":

Tertullian interprets the law as a shadow of the coming Christ, a theme also present in Irenaeus’s writings. In Adversus Haereses IV.2.7, Irenaeus explains that the Old Testament law foreshadows the work of Christ, who fulfills and brings the substance of the law.

Irenaeus citation: “The law was a shadow of the good things to come, but the substance is Christ.”

7. Colossians 2:14 - "Having canceled the record of debt":

Tertullian emphasizes that Christ canceled the law’s demands through His crucifixion. Irenaeus, in Adversus Haereses III.18.7, similarly points out that the law’s curse was lifted through Christ’s death, showing continuity between the law and the Gospel rather than a radical rupture as Marcion claimed.

Irenaeus citation: “Christ nailed the curse of the law to the cross, redeeming us from its demands.”

8. Colossians 2:20-22 - "Do not handle, do not taste, do not touch":

Tertullian argues against ascetic practices that deny the goodness of creation. Irenaeus in Adversus Haereses I.24.5 similarly criticizes heretical asceticism that teaches the rejection of material things, emphasizing that creation is good because it comes from God.

Irenaeus citation: “Those who reject the material world deny the goodness of the Creator, who made all things.”

9. Colossians 3:9-10 - "Put off the old self...put on the new self":

Tertullian interprets this as a reference to Christian transformation, which echoes Irenaeus’s interpretation in Adversus Haereses V.12.3, where he links putting off the old self to the renewal of humanity in Christ, in contrast to the Gnostic view that denies the need for physical resurrection.

Irenaeus citation: “In Christ, humanity is renewed, putting off the old man and putting on the new, restored in the image of God.”

10. Colossians 3:11 - "Christ is all and in all":

Tertullian stresses the universality of Christ, breaking down distinctions between Jew and Greek, slave and free. Irenaeus, in Adversus Haereses III.16.9, also highlights this theme to show that Christ unites all people under the one God, countering Marcion’s divisive theology.

Irenaeus citation: “In Christ, there is no distinction, for He is Lord of all, bringing unity under the one Creator.”

These citations show how Tertullian's arguments in Adversus Marcionem align with Irenaeus’s earlier refutation of Marcion, particularly regarding the integrity of Paul’s letters and their interpretation within the framework of the Creator's role.

Here is the analysis of the section in Adversus Marcionem 20, focused on Tertullian’s potential reuse of an original treatise by Irenaeus that argued from Paul’s canonical letters against Marcion, without assuming or proving that either Tertullian or Irenaeus had a copy of Marcion’s alleged "falsified collection of the letters of Paul":

1. Philippians 1:15-18 - Preaching Christ from different motives:

Tertullian discusses the diverse motives behind the preaching of Christ but maintains that it is still the same Christ being preached. This echoes Irenaeus’s argument in Adversus Haereses III.16.8, where Irenaeus focuses on the universality of the preaching of Christ and the preservation of the apostolic message, regardless of the preachers’ intentions.

Irenaeus citation: “Some preach Christ from envy, but still, Christ is preached, and the message remains unaltered.”

2. Philippians 2:6-7 - Christ emptying Himself, taking the form of a servant:

Tertullian interprets Christ's humility in taking human form as genuine, refuting Marcion’s claim of a phantom body. This mirrors Irenaeus’s argument in Adversus Haereses III.19.3, where Irenaeus argues against docetism, emphasizing that Christ's humanity was real and necessary for salvation.

Irenaeus citation: “The Word truly became flesh, and His incarnation was necessary for the redemption of mankind.”

3. Philippians 2:8 - Christ’s death on the cross:

Tertullian emphasizes the reality of Christ’s death on the cross, arguing that it could not have been merely a phantom sacrifice. Irenaeus makes a similar point in Adversus Haereses III.18.5, arguing that Christ’s real suffering and death were essential to human redemption, and a mere illusion would have been ineffective.

Irenaeus citation: “If He had not truly suffered, He could not have redeemed humanity.”

4. Philippians 3:7-8 - Counting all things as loss for Christ: Tertullian points out that Paul regarded his former status as loss compared to knowing Christ, which is consistent with Irenaeus’s teaching that the knowledge of Christ surpasses all earthly things (Adversus Haereses IV.34.4). Irenaeus also argues that the pursuit of knowledge of God through Christ surpasses adherence to the Law.

Irenaeus citation: “The knowledge of Christ surpasses all, even the Law, which was only a preparation for His coming.”

5. Philippians 3:20 - Our citizenship in heaven:

Tertullian connects this to the promise made to Abraham, showing continuity between the Old Testament and the New Testament, similar to Irenaeus in Adversus Haereses IV.16.2, where Irenaeus emphasizes the continuity of God’s plan through the promises made to the patriarchs, fulfilled in Christ.

Irenaeus citation: “The promises made to Abraham find their fulfillment in Christ, and through Him, we become citizens of heaven.”

6. Philippians 3:21 - Christ will transform our lowly bodies:

Tertullian insists on the resurrection of the body, countering Marcion’s denial of bodily resurrection. Irenaeus, in Adversus Haereses V.6.2, also defends the resurrection of the flesh, arguing that the body will be transformed and glorified in the resurrection, just as Christ’s body was.

Irenaeus citation: “The resurrection of the body is essential, as Christ’s own resurrection was in the flesh, and our bodies will be transformed like His.”

These citations provide evidence that Tertullian is reusing concepts and arguments likely borrowed from an earlier treatise by Irenaeus, especially in their shared focus on Christ’s genuine incarnation, the reality of His death, and the continuity between the Old Testament promises and the New Testament fulfillment in Christ. Both authors also counter Marcion’s denial of the body’s resurrection and assert the unity of God’s plan across Scripture.

Here is a specific analysis of Tertullian’s Adversus Marcionem Book Three.

Evidence of Reusing Irenaeus's Treatise

Chapter 1:

Defense of the Creator’s Divinity in Christ's Teaching

Tertullian begins by asserting that Christ preached the Creator God, and the apostles continued this teaching, refuting the idea of any alternative deity before Marcion's influence. This aligns with Irenaeus's argument in Adversus Haereses III.11.7, where Irenaeus insists that both Christ and the apostles consistently proclaimed the God of the Old Testament, the Creator.

Irenaeus citation: “The apostles... acknowledged one God, the same who had made all things by His Word.”
Gospel of Luke: Tertullian’s defense resonates with Luke 10:21, where Jesus thanks the Father, Lord of heaven and earth, affirming the Creator’s role in Jesus' mission.

Chapter 2:

The Precedence of the Father Over the Son

Tertullian argues that the Father should have first declared the Son, rather than the Son declaring the Father, reflecting an expected order of revelation. This echoes Irenaeus in Adversus Haereses IV.6.2, where Irenaeus affirms that the Father’s will is manifested through the Son, but always in alignment with the Father's authority.

Irenaeus citation: “The Son reveals the Father, and the Father is revealed through the Son, according to the Father's good pleasure.”
Paul’s Letters: In Colossians 1:15–16, Paul emphasizes Christ as the image of the invisible God, with all things created through Him, suggesting the Father’s preeminence over the Son while affirming the unity of creation.

Gradual Revelation and Prophecy

Tertullian argues that Christ’s coming should have been preceded by prophecies to support faith, which matches Irenaeus’s emphasis on Christ fulfilling Old Testament prophecies, as shown in Adversus Haereses III.21.3. Irenaeus stresses that Christ was prophesied by the Old Testament scriptures, confirming His identity and mission.

Irenaeus citation: “The prophets announced Him, and He fulfilled their prophecies.”

Gospel of Luke: Luke 24:44 presents Jesus explaining that everything written about Him in the Law of Moses, the Prophets, and the Psalms must be fulfilled, underlining the prophetic foundation of Christ’s coming.

Chapter 3:

Miracles Alone Do Not Prove Christ’s Authenticity

Tertullian refutes the idea that Christ’s miracles alone should validate His identity, as false prophets could also perform wonders. Irenaeus, in Adversus Haereses II.31.2, makes a similar point, cautioning against relying solely on miraculous signs, as even heretics could imitate them.

Irenaeus citation: “It is not by signs and wonders alone that we know Him, but by His fulfillment of the Scriptures.”
Gospel of Luke: In Luke 11:29, Jesus warns against those seeking signs, pointing instead to His role in fulfilling God's plan, as Jonah was a sign to Nineveh.

Christ's Identity Linked to the Creator’s Prophecies

Tertullian emphasizes that Christ was prophesied by the Creator’s prophets and that any claim to a different Christ would require a new set of prophecies and evidence. This argument mirrors Irenaeus in Adversus Haereses III.22.4, where he argues that Christ is the fulfillment of the Creator’s plan, and any new Christ would have to establish an entirely new divine order.

Irenaeus citation: “The Christ whom the apostles preached is the same as the one promised by the prophets.”
Paul’s Letters: In Romans 1:2–4, Paul stresses that the Gospel concerning Jesus Christ was promised beforehand through the prophets in the holy Scriptures, linking Jesus to the Creator’s plan.

The Continuity of Divine Revelation

Tertullian refutes the notion of a sudden, unprophesied appearance of Christ. Irenaeus argues similarly in Adversus Haereses III.16.3, emphasizing the continuous revelation of God through the Law and the Prophets, culminating in Christ.

Irenaeus citation: “Christ came not suddenly or without warning, but was revealed according to the plan of God, foretold by the prophets.”

Gospel of Luke: In Luke 24:27, Jesus explains to the disciples on the road to Emmaus how all the Scriptures pointed to Him, showing the continuity of revelation.

Summary of Evidence So Far:

Tertullian’s arguments in this passage bear striking similarities to Irenaeus’s Adversus Haereses:

• Both argue from the premise that Christ and the apostles preached the Creator God.
  Both refute the idea of Christ's sudden appearance without prophetic precedent.
  Both emphasize that miracles alone do not validate Christ’s mission; it is His fulfillment of prophecy that proves His authenticity.
  Both highlight the importance of the canonical Gospel of Luke and Paul’s letters in affirming the true Christ, as opposed to any falsified or alternative version of these texts.

This specific evidence shows how Tertullian reused key arguments from Irenaeus’s work, particularly focusing on Paul’s letters and the Gospel of Luke, to counter Marcion’s claims and affirm the Creator God’s divinity and Christ’s role as His Son.

Chapter 4:

Timing of Christ's Revelation

Tertullian's Argument: Tertullian argues that Marcion's Christ came "before the Father's profession" and "before the authority of the sender" (Chapter 4.1), which he finds problematic. He claims that the Creator should have revealed His own Christ first, following divine order.

Irenaeus's Similar Argument: Irenaeus, in Adversus Haereses III.16.1, argues similarly, stating that Christ must be understood as coming from the Creator God and that the order of revelation is crucial. Both authors assert that Christ's coming must align with the established plan of the Creator.

Irenaeus citation: “Christ was revealed by the will of the Father, not by chance, but according to the plan of salvation.”

The Creator's Patience and Christ's Arrival

Tertullian's Argument: Tertullian criticizes Marcion's idea that the Creator waited too long to reveal His Christ. He claims that if Marcion’s god was truly patient, he should have waited until after the Creator’s Christ to reveal his own (Chapter 4.2). This aligns with the idea of a divinely ordered progression.

Irenaeus's Similar Argument: Irenaeus makes a similar point in Adversus Haereses III.11.8, where he argues that Christ’s coming was foretold long before and fulfilled in due time, following the Creator’s design.

Irenaeus citation: “All things were foretold concerning the coming of Christ by the Creator’s prophets, and were brought to pass in their proper time.”

The Delay in Revelation

Tertullian's Argument: Tertullian criticizes Marcion’s concept that his Christ came “too late” after the Creator’s work was already established (Chapter 4.3). He argues that this renders Marcion’s Christ ineffective since the Creator’s Christ had already been revealed.

Irenaeus's Similar Argument: Irenaeus addresses a similar issue in Adversus Haereses III.21.4, asserting that the true Christ had been consistently prophesied and that any later "Christ" would be a false claimant.

Irenaeus citation: “The Creator’s Christ was prophesied and revealed according to God’s plan. Any other so-called Christ would be a deceiver.”

Chapter 5:

Prophetic Announcements

Tertullian's Argument: Tertullian highlights how the Creator’s scriptures (i.e., the Old Testament) announced Christ’s coming and role. He emphasizes that Marcion’s Christ was never prophesied, making his coming implausible (Chapter 5.2).
Irenaeus's Similar Argument: Irenaeus argues in Adversus Haereses III.10.5 that the Creator’s prophets clearly foretold the coming of Christ, and that only the Creator’s Christ could fulfill these prophecies.

Irenaeus citation: “Christ is the fulfillment of the law and the prophets, proclaimed by the Creator’s servants.”

Figurative Language in Prophecy

Tertullian's Argument: Tertullian points to the use of figurative language in the prophets, where future events are sometimes described as if they have already occurred (Chapter 5.2). He uses this to explain how the prophets foretold Christ's coming, which was part of the Creator's plan.

Irenaeus's Similar Argument: Irenaeus, in Adversus Haereses IV.26.1, also emphasizes the use of figurative language in prophecy, arguing that these prophecies were fulfilled in Christ.

Irenaeus citation: “The prophets spoke in figurative terms about the coming Christ, and their words were fulfilled in the incarnation of Jesus.”

Allegory in Scripture

Tertullian's Argument: Tertullian argues that many of the prophecies were allegorical and should be interpreted figuratively. He mentions examples from Isaiah, where allegorical language points to Christ’s suffering (Chapter 5.3).

Irenaeus's Similar Argument: Irenaeus, in Adversus Haereses IV.20.1, also stresses the importance of interpreting prophecies allegorically, especially those regarding Christ’s suffering and redemption.

Irenaeus citation: “The sufferings of Christ were foretold in the prophets, often through allegory and parable, to be fully revealed in His coming.”

Chapter 6:

Jewish Misunderstanding of Christ

Tertullian's Argument: Tertullian claims that the Jews failed to recognize Christ, despite the clear prophecies about Him, because their understanding had been darkened by their own disobedience (Chapter 6.4). This aligns with his broader argument that the Creator’s Christ was always the one foretold, but that human error led to His rejection.

Irenaeus's Similar Argument: Irenaeus, in Adversus Haereses III.21.2, argues that the Jewish rejection of Christ was a fulfillment of prophecy, and that their blindness was foretold as part of God’s plan.

Irenaeus citation: “The prophets foretold that Christ would be rejected by His own people, but this was part of God’s greater plan for salvation.”

The Jews' Failure to Recognize the Creator's Christ

Tertullian's Argument: Tertullian asserts that the Jews did not recognize the true Christ because they were blinded by their sins (Chapter 6.6). He uses this to argue against Marcion's claim that the Jews were correct in rejecting Christ because He was not the true Messiah.

Irenaeus's Similar Argument: Irenaeus, in Adversus Haereses IV.2.3, makes a similar point, noting that the Jewish leaders failed to understand the prophecies concerning Christ due to their own hardness of heart.
Irenaeus citation: “The Jews did not recognize Christ because their hearts were hardened, fulfilling the very prophecies that they did not understand.”

Summary of Specific Citations

Tertullian's arguments in this passage exhibit significant parallels to those of Irenaeus, especially concerning the canonical Gospel of Luke and the letters of Paul. Both writers:

• Emphasize the importance of prophecy in affirming Christ’s role as the Creator’s Messiah.
  Argue that the Creator's Christ was foretold, while Marcion's alleged Christ lacked any prophetic foundation.
  Use both figurative and literal interpretations of prophecy to support the continuity between the Old Testament and the Gospel.
  Highlight the Jewish failure to recognize Christ as part of a divine plan that fulfills the Creator’s will, not as evidence of an alternative deity or Christ.

These specific citations illustrate how Tertullian may have reused an original treatise by Irenaeus to combat Marcion’s claims, drawing heavily on both the Gospel of Luke and Paul’s letters to defend the Creator's Christ.

Chapter 7:

Two Advents of Christ

Tertullian's Argument: Tertullian discusses the two advents of Christ—first in humility, and then in glory. He claims the Jews misunderstood and expected only the glorious coming of Christ, which led them to reject Him during His first advent.

Connection to Irenaeus: In Adversus Haereses III.16.2, Irenaeus makes a similar argument, stating that the Jews expected a glorious, conquering Messiah and failed to recognize Christ's humble first advent. Both argue that the failure to understand the prophetic nature of Christ's humility led to the Jews’ rejection of Jesus.

Irenaeus citation: "They did not know that He who was in a humble condition... was also to be the glorious one."
Connection to Luke and Paul: Luke 24:26 reflects the same message, where Jesus explains that the Messiah had to suffer before entering His glory. Paul in Philippians 2:6-11 speaks of Christ's humility followed by exaltation, which fits with Tertullian's and Irenaeus' two-stage understanding of Christ's coming.

Chapter 8:

Refuting the Docetic View of Christ’s Flesh

Tertullian's Argument: Tertullian attacks Marcion’s docetic Christology, which claimed that Christ's physical form was an illusion. He insists that Christ's suffering, death, and resurrection were real and essential to the Christian faith (III.8).

Connection to Irenaeus: Irenaeus also strongly opposes docetism, as seen in Adversus Haereses III.22.1, where he argues that the reality of Christ's flesh and suffering is crucial to the doctrine of salvation. Both reject the idea that Christ’s body was only an illusion.
Irenaeus citation: "The Word became flesh... He truly suffered and rose again, not in appearance, but in reality."

Connection to Luke and Paul: Luke’s Gospel emphasizes the physical reality of Christ’s resurrection, particularly in Luke 24:39, where Jesus tells His disciples to touch His flesh and bones. Paul in 1 Corinthians 15:3-4 stresses that Christ's death and resurrection are foundational truths for salvation, directly opposing the docetic view.

Chapter 9:

Angels and True Humanity

Tertullian's Argument: Tertullian argues against the notion that angels appearing in human form (such as in the story of Abraham) were merely phantasms. He insists that their flesh was real, as was Christ’s (III.9).

Connection to Irenaeus: Irenaeus also discusses the nature of angels and Christ’s humanity in Adversus Haereses IV.7.2, where he argues that Christ’s incarnation was not an illusion but a true manifestation of God in human flesh. Both stress that the reality of Christ’s human form is essential.

Irenaeus citation: "He became man and dwelt among us, and His form was real."

Connection to Luke and Paul: In Luke 20:36, Jesus mentions that in the resurrection, people will be like angels. This supports Tertullian’s argument that if angels can assume real human form, so can Christ. Paul in 1 Corinthians 15:49 speaks of the transformation into the likeness of the heavenly man, further supporting the idea of true, embodied existence in resurrection.

Other Supporting Evidence from the Chapters:

Luke and Prophecy: In Chapter 7, Tertullian refers to the suffering servant prophecies from Isaiah (Isaiah 53), which are fulfilled in Christ. This aligns with Luke 24:44, where Jesus explains that everything written about Him in the Law of Moses, the Prophets, and the Psalms must be fulfilled. Both Tertullian and Irenaeus (III.16.3) use this framework to argue that Christ's advent was prophesied.

Irenaeus citation: “He Himself declared that the things written concerning Him in the Law, the Prophets, and the Psalms were to be fulfilled.”

Paul’s Letters on Resurrection: Tertullian uses Paul’s argument from 1 Corinthians 15 (III.8) to affirm the bodily resurrection of Christ. Irenaeus also relies on this Pauline teaching to refute the docetic view, pointing out that if Christ did not truly rise, there would be no resurrection for believers.

Irenaeus citation: “If the Lord’s body was not real, then neither will we rise in reality.”

Summary of Specific Citations:

• Chapter 7: Tertullian reuses Irenaeus’ argument that the Jews misunderstood the prophecies of Christ’s two advents (III.16.2).
  Chapter 8: Tertullian draws on Irenaeus’ argument against docetism (III.22.1), asserting the real suffering, death, and resurrection of Christ, citing Paul’s letters.
  Chapter 9: Tertullian parallels Irenaeus in arguing for the reality of angelic and human flesh, citing both Luke and Paul on resurrection and the transformation of the body (IV.7.2).

This analysis demonstrates how Tertullian, while not having access to Marcion's alleged falsified texts, repurposed Irenaeus’ original arguments based on canonical texts, particularly Luke and Paul’s letters, to refute Marcion.

Chapter 10:

Rejection of the Flesh as Earthly

Tertullian's Argument: Tertullian argues against Marcion's claim that Christ did not come in true flesh but only in a likeness of human flesh (10.1). He insists that Christ’s flesh had to be real for the Incarnation to have meaning, dismissing the idea that God would use an inferior, earthly body as a mere illusion.

Connection to Irenaeus: In Adversus Haereses III.22.2, Irenaeus likewise rejects docetism, arguing that the Incarnation was real and that Christ truly became flesh. Both argue against the idea of a “phantom” Christ.

Irenaeus citation: "He truly took upon Himself human flesh, that through it He might defeat death."

Luke’s Gospel: Tertullian’s reference to Christ’s true human form echoes Luke 24:39, where the resurrected Jesus proves His physical reality by asking the disciples to touch His hands and feet.

Chapter 11:

Marcion’s Fear of Christ’s Humanity

Tertullian's Argument: Tertullian points out that Marcion rejected the idea of Christ’s physical birth because acknowledging Christ’s birth would imply He belonged to the Creator’s world (11.1). He argues that Christ’s human birth, as evidenced by various gospel stories, cannot be denied without undermining the truth of the Incarnation.

Connection to Irenaeus: Irenaeus, in Adversus Haereses III.16.2, also addresses Marcion’s denial of Christ’s human birth, arguing that the Gospels (especially Luke’s Gospel) clearly show Christ’s human origins. Both Tertullian and Irenaeus claim that rejecting Christ’s birth leads to denying the full reality of His redemptive work.

Irenaeus citation: "He was born as a man, so that by this means the birth and suffering of Christ could save humanity."

Luke’s Gospel: Tertullian references stories such as Luke 11:27 (the woman proclaiming “Blessed is the womb that bore you”) and Luke 8:19-21 (Jesus’ mother and brothers) to emphasize Christ’s human birth and family ties, which contradict Marcion's belief in a purely divine, non-physical Christ.

Chapter 12:

Isaiah’s Prophecies and Christ as "Emmanuel"

Tertullian's Argument: Tertullian explains that the prophecy of Isaiah 7:14, which refers to Emmanuel ("God with us"), applies to Christ. He refutes Marcion’s claim that this prophecy has no relevance to Christ, arguing that “God with us” was fulfilled in Christ’s incarnation (12.1).

Connection to Irenaeus: Irenaeus also uses Isaiah 7:14 in Adversus Haereses III.16.3, where he defends the prophecy of Emmanuel as being fulfilled in Christ. Both Tertullian and Irenaeus use this prophecy to assert the truth of Christ’s incarnation and His identity as the true Son of God.

Irenaeus citation: "For He was truly 'God with us,' fulfilling the prophecy of Isaiah, that a virgin shall conceive."

Luke’s Gospel: Tertullian connects the prophecy of Emmanuel to Christ’s mission in Luke 1:32-33, where Jesus is described as the Son of the Most High, whose kingdom will never end—an echo of the prophecy of Emmanuel being the sign of God's presence with His people.

Chapter 13:

Christ’s Childhood and the Prophecy of Damascus

Tertullian's Argument: Tertullian tackles the prophecy from Isaiah 8:4, which Marcion misinterprets as a military prophecy. Tertullian argues that the prophecy symbolically refers to Christ’s early childhood and His spiritual conquest of Damascus, not through war but through divine intervention, fulfilled by the visit of the Magi.

Connection to Irenaeus: Irenaeus in Adversus Haereses III.21.4 similarly interprets Old Testament prophecies symbolically, applying them to Christ’s life and mission. Both Irenaeus and Tertullian use allegorical methods to explain prophecies about Christ’s early life and the role of the Magi.

Irenaeus citation: "The visit of the Magi... fulfilled the prophecy of the coming King."

Luke’s Gospel: The visit of the Magi, which Tertullian references, is echoed in the broader birth narrative of Christ in Luke’s Gospel, where Jesus’ infancy is marked by prophetic declarations and signs of His divine mission.

Specific Citations Summary:

• Chapter 10: Tertullian draws from Irenaeus’s argument that the Incarnation involved a true body, not a mere image, and uses Luke 24:39 to argue for the physical reality of Christ’s flesh.
  Chapter 11: Tertullian reuses Irenaeus’s argument that Christ’s human birth is attested in the Gospels (Luke 11:27, 8:19-21) and cannot be denied without rejecting Christ’s entire mission.
  Chapter 12: Tertullian echoes Irenaeus in interpreting Isaiah 7:14 (Emmanuel) as a prophecy of Christ’s incarnation, connecting it to Luke 1:32-33.
  Chapter 13: Tertullian builds on Irenaeus’s approach to allegorical prophecy, using Isaiah 8:4 to refer to Christ’s childhood, paralleling the fulfillment seen in Luke’s infancy narrative.

This analysis reveals that Tertullian reused themes and specific scriptural arguments from Irenaeus, particularly from the canonical Gospel of Luke and the letters of Paul, in his refutation of Marcion, without directly referencing Marcion’s alleged falsified texts.

Chapter 14:

Allegorical Interpretation of the "Sword"

Tertullian's Argument: Tertullian interprets the "sword" mentioned in Psalm 45:3 and Revelation 1:16 allegorically as the Word of God rather than a literal weapon, stating that Christ is a spiritual warrior. He links the sword to the teachings of Christ and the two testaments (the Law and the Gospel), using the sword to fight spiritual battles (14.3).

Connection to Irenaeus: In Adversus Haereses III.22.4, Irenaeus also interprets the sword as a spiritual metaphor, arguing that Christ's "warfare" is one of truth and wisdom, not physical violence. Both reject literal interpretations of martial language.
Irenaeus citation: "The Word of God is sharper than any two-edged sword."

Luke’s Gospel: The reference to the sword connects to Luke 12:51, where Jesus says, "Do you think I came to bring peace on earth? No, I tell you, but division." Tertullian interprets this "sword" as the spiritual division caused by Christ's teachings.

Chapter 15:

The Name "Christ"

Tertullian's Argument: Tertullian insists that the name "Christ" belongs exclusively to the Creator’s Son and cannot be shared by any other deity, especially not Marcion’s god. He uses Paul’s writings in 1 Corinthians 8:5 to argue that while many gods may be named, the title "Christ" is reserved for the one anointed by the Creator (15.2).

Connection to Irenaeus: Irenaeus makes a similar argument in Adversus Haereses III.16.8, where he discusses the uniqueness of the name "Christ" and its link to the anointing by God. Both Tertullian and Irenaeus emphasize that "Christ" is not a general title but one with specific divine significance.

Irenaeus citation: "The name 'Christ' belongs to the one who is truly anointed by the Creator."
Paul’s Letters: Tertullian’s argument relies heavily on Paul's theology, particularly passages like Philippians 2:9-11, where Paul emphasizes that God gave Jesus the name above all names, making "Christ" a unique and exalted title.

Chapter 16:

The Name "Jesus"

Tertullian's Argument: Tertullian addresses Marcion's reluctance to acknowledge the name "Jesus," arguing that the name was divinely ordained. He refers to the story of Joshua (originally named Hoshea) being renamed by Moses in Numbers 13:16 as a type of Christ, showing that the name "Jesus" had prophetic significance (16.3-4).

Connection to Irenaeus: Irenaeus also sees the renaming of Joshua as a prefiguration of Jesus in Adversus Haereses III.16.3. Both stress that the name "Jesus" was not an arbitrary choice but was laden with meaning and purpose, particularly as it pertains to the salvation of God’s people.

Irenaeus citation: "The name Joshua, which was given by Moses, prefigures Jesus, the Savior of the world."
Luke’s Gospel: Tertullian’s discussion of the name "Jesus" connects to Luke 1:31, where the angel tells Mary that she will name her son Jesus because "He will save His people from their sins," further cementing the divine origin of the name.

Chapter 17:

Christ’s Humble Appearance

Tertullian's Argument: Tertullian argues that Christ’s humble, unattractive appearance, as described in Isaiah 53:2-3, matches the depiction of Christ in the Gospels. He points out that Christ's lack of worldly glory is a fulfillment of the prophecy, making Him the true Messiah of the Creator (17.1-2).

Connection to Irenaeus: Irenaeus uses the same prophecy in Adversus Haereses III.16.1 to argue that Christ’s humility and suffering were foretold and that these characteristics confirm His identity as the Creator’s Son. Both Tertullian and Irenaeus use Isaiah’s depiction of a suffering servant to counter Marcion’s claim of a purely divine Christ.

Irenaeus citation: "He was without beauty or majesty, despised and rejected by men."

Luke’s Gospel: The humility of Christ connects to Luke 2:7, where Jesus is born in a manger, and Luke 9:58, where Jesus says, "The Son of Man has nowhere to lay his head." Tertullian emphasizes that Christ’s lowly status on earth is in line with the Creator’s plan, as shown in the Gospel.

Specific Citations Summary:

• Chapter 14: Tertullian’s allegorical interpretation of the "sword" draws from Irenaeus’s spiritual reading of martial language (cf. Adversus Haereses III.22.4) and Paul’s use of the "armor of God" in Ephesians 6:14-17.
  Chapter 15: Tertullian’s defense of the name "Christ" parallels Irenaeus’s assertion of its divine uniqueness (cf. Adversus Haereses III.16.8) and aligns with Paul’s theology of Christ’s exalted name in Philippians 2:9-11.
  Chapter 16: Tertullian’s discussion of the name "Jesus" is rooted in the typology of Joshua and mirrors Irenaeus’s view of the name’s prophetic significance (cf. Adversus Haereses III.16.3).
  Chapter 17: Tertullian’s use of Isaiah 53:2-3 to describe Christ’s humble appearance reflects Irenaeus’s reliance on the same passage to argue for the authenticity of Christ’s humanity and suffering (cf. Adversus Haereses III.16.1).

This analysis demonstrates that Tertullian’s arguments in this section of Adversus Marcionem closely follow themes and scriptural interpretations found in Irenaeus’s earlier writings, particularly from the canonical Gospel of Luke and the letters of Paul. Both authors reject Marcion’s portrayal of Christ as a purely divine figure, emphasizing the truth of His incarnation and His role as the fulfillment of Old Testament prophecies.

Chapter 18:

Prefiguration of Christ’s Passion and the Cross

Tertullian's Argument: Tertullian addresses Marcion's denial of the cross, arguing that the crucifixion was prefigured throughout the Old Testament. He begins by discussing the figure of Isaac carrying the wood for his sacrifice (Gen 22:6) as a prefiguration of Christ bearing the cross (18.2).

Connection to Irenaeus: Irenaeus in Adversus Haereses IV.5.4 similarly argues that Isaac's carrying the wood prefigures Christ carrying the cross, showing how Old Testament types foreshadow New Testament events.

Irenaeus citation: "Isaac, who was led by his father to be sacrificed, was a type of Christ, who carried His own cross."
Paul's Letters: Tertullian also references Deuteronomy 21:23, which Paul interprets in Galatians 3:13 to explain that Christ became a curse by hanging on a tree. Tertullian uses this interpretation to argue that the type of death—crucifixion—was always part of God's plan, despite its association with a curse.

Joseph as a Type of Christ: Tertullian interprets Joseph’s persecution by his brothers (Gen 37) as another prefiguration of Christ’s suffering (18.3). He also interprets the blessing of Joseph in Deuteronomy 33:17, where his "horns" (strength) are likened to the cross (18.4). This, Tertullian argues, points to Christ’s dual role as judge and savior.

Connection to Irenaeus: Irenaeus also identifies Joseph as a type of Christ in Adversus Haereses IV.21.1, where he explains how Joseph’s suffering and subsequent exaltation foreshadows Christ’s death and resurrection.

Irenaeus citation: "Joseph’s experiences prefigured those of Christ, who would suffer but then be exalted over all."
Chapter 19: The Cross and Resurrection Foretold in Prophecy
Tertullian's Argument: Tertullian points to Psalm 96:10 (LXX), "The Lord reigns from the tree," as a prophetic reference to Christ reigning from the cross (19.1). He also references Isaiah 9:6 to explain how Christ’s government rests on His shoulder, symbolizing the weight of the cross (19.2).

Connection to Irenaeus: Irenaeus similarly interprets these passages in Adversus Haereses III.6.4, where he argues that the prophecy of the government on Christ’s shoulders is fulfilled in His crucifixion. Both Tertullian and Irenaeus use the same prophetic texts to argue that the crucifixion was foretold.

Irenaeus citation: "The prophecy of the government on His shoulder is realized in Christ, who bears the cross as a sign of His kingship."
Jeremiah’s Prophecy: Tertullian references Jeremiah 11:19, where the prophet speaks of throwing "wood into his bread," interpreting this as a prophecy of Christ’s body, which He later calls "bread" during the Last Supper (19.3). This connects to Luke 22:19, where Christ institutes the Eucharist.

Connection to Irenaeus: Irenaeus makes a similar connection in Adversus Haereses IV.17.5, arguing that the bread and wine are symbolic of Christ’s body and blood, prefigured in Old Testament types.

Irenaeus citation: "He proclaimed the cup and the bread as His body and blood, foreshadowed by the prophets."

Psalm 22 and Crucifixion: Tertullian cites Psalm 22:16, which describes the piercing of hands and feet, as a prophecy of the crucifixion (19.5). He also refers to the plea for deliverance from the "horns of the unicorn" (19.6), interpreting this as a reference to the shape of the cross.

Connection to Irenaeus: Irenaeus in Adversus Haereses III.16.9 also cites Psalm 22 as a clear prophecy of the crucifixion, particularly the piercing of Christ’s hands and feet.

Irenaeus citation: "The Psalm clearly predicts the sufferings of Christ, especially His crucifixion, where His hands and feet were pierced."

Chapter 20:

Christ’s Universal Reign

Tertullian's Argument: Tertullian moves to the post-crucifixion reign of Christ, citing Psalm 2:7-8, where God declares to His Son, "Ask of me, and I will give you the nations as your inheritance" (20.3). He argues that this prophecy is fulfilled in Christ’s reign over all nations through the spread of the Gospel.

Connection to Irenaeus: Irenaeus in Adversus Haereses III.6.1 similarly argues that Christ's universal reign was foretold in the Psalms, and this reign is realized through His death and resurrection, which leads to the conversion of the nations.

Irenaeus citation: "Christ, who was given dominion over the nations, is the fulfillment of the Psalms and the prophets."

Isaiah’s Prophecy of Light to the Nations: Tertullian also cites Isaiah 42:6 and 55:4, where Christ is described as a light to the nations and a leader for the people (20.4-5). He argues that Christ’s mission to open the eyes of the blind and free the captives is fulfilled in His redemptive work.

Connection to Irenaeus: Irenaeus draws on the same passages in Adversus Haereses III.20.4 to explain Christ’s role as the liberator and the light for the Gentiles, noting how the Gentiles have turned to Christ in fulfillment of these prophecies.

Irenaeus citation: "The prophets foretold that Christ would be a light to the nations and a redeemer for the people, fulfilled in the spread of the Gospel."

Specific Citations Summary:

• Chapter 18: Tertullian’s use of the Isaac and Joseph narratives as types of Christ (cf. Gen 22, Gen 37, and Deut 33) echoes Irenaeus’s typological readings in Adversus Haereses IV.5.4 and IV.21.1, both using Old Testament figures to prefigure Christ’s crucifixion.
  Chapter 19: Tertullian’s argument about the crucifixion foretold in Psalm 96, Isaiah 9, and Psalm 22 parallels Irenaeus’s use of these same passages (cf. Adversus Haereses III.6.4 and III.16.9) to argue for the necessity and prophecy of Christ’s death on the cross.
  Chapter 20: Tertullian’s references to the universal reign of Christ (Psalm 2 and Isaiah 42) align closely with Irenaeus’s explanation of Christ’s kingship and role as a light to the nations (cf. Adversus Haereses III.6.1 and III.20.4).

This analysis demonstrates that Tertullian was reusing and building upon arguments made by Irenaeus, who relied on canonical scriptures, particularly the Gospel of Luke and the letters of Paul, to argue against Marcion’s heretical views. Both authors reject Marcion’s version of Christ, emphasizing instead the fulfillment of Old Testament prophecies in the canonical accounts of Christ’s passion, death, and resurrection.

Chapter 21:

The Nations and Christ’s Universality

Argument from Isaiah: Tertullian begins by arguing that the calling of the nations to Christ was foretold by Isaiah (Isa. 42:4). He connects this prophecy to the fulfillment of Christ’s message, showing how the nations—Gentiles—were prophesied to be drawn to the Creator's Christ, refuting the Marcionite claim that their "better" Christ was meant to save all of humanity.

Connection to Irenaeus: Irenaeus also uses the same prophecies in Adversus Haereses III.22.4, where he cites Isaiah to show that Christ was destined to call all nations. Both Tertullian and Irenaeus draw from Isaiah to argue that the Creator’s Christ was intended to be the savior of all people, not just the Jewish population.

Irenaeus citation: “Isaiah said, ‘And in his name, the nations shall hope,’ demonstrating the universality of the Creator’s Christ.”
Argument from Luke and Paul: Tertullian references the mission of the apostles, whose feet are described as "beautiful" in carrying the message of peace to the nations (Isa. 52:7). He uses Paul’s language from Romans 10:15 to connect the fulfillment of this prophecy to the work of the apostles.

Connection to Irenaeus: Irenaeus similarly argues from Isaiah and Paul’s letters in Adversus Haereses III.16.3, where he states that the apostles were the messengers of Christ who brought the gospel to the nations. Both authors see the apostles’ mission as the fulfillment of prophecy.

Irenaeus citation: "The apostles were the messengers sent by the Creator, as Isaiah declared, bringing the good news to all nations."

Critique of Marcion’s Two Christs: Tertullian directly critiques Marcion’s division of Christ into two separate figures—one for the Jews and one for the Gentiles. He counters this with the fact that the Creator’s Christ came for all, as evidenced by the early Christian movement, which was already calling all nations to the Creator’s kingdom before Marcion.

Connection to Irenaeus: In Adversus Haereses III.11.8, Irenaeus refutes Marcion’s division of Christ, emphasizing the continuity between the Old and New Testaments and the universality of Christ’s mission. Tertullian echoes this same line of reasoning.
Irenaeus citation: "There is only one Christ, sent by the Creator, for both Jews and Gentiles alike, as all prophecy and the apostles demonstrate."

Chapter 22:

The Apostles’ Fulfillment of Prophecy

Apostolic Preaching as Fulfillment: Tertullian asserts that the apostles fulfilled Old Testament prophecies, such as Psalm 19:4, which speaks of their message going to the ends of the earth. He emphasizes that the apostles preached the law from Zion and the word from Jerusalem, a fulfillment of Isaiah 2:3.

Connection to Irenaeus: Irenaeus makes a similar point in Adversus Haereses III.13.1, where he argues that the apostles’ preaching fulfilled the same prophecies from Isaiah and the Psalms. Both authors view the spread of the Gospel by the apostles as a direct continuation of the Creator’s plan.

Irenaeus citation: "The apostles, by their preaching, fulfilled the ancient prophecies, carrying the word of the Creator to the ends of the earth."

Isaiah’s Call to Depart: Tertullian references Isaiah 52:11, where the prophet calls on the people to "depart" and be separate, referring to the apostles’ separation from the synagogue. He interprets this as a command to break away from the old Jewish traditions and embrace the new covenant in Christ.

Connection to Irenaeus: Irenaeus also cites this verse in Adversus Haereses III.21.4, explaining how the apostles were called to separate themselves from the old covenant and bring the message of Christ to the nations. This highlights the shared use of prophetic texts to argue for the legitimacy of the apostles’ mission.

Irenaeus citation: "The apostles, following Isaiah’s call, separated from the synagogue to bring the message of the Creator’s Christ to all nations."

Chapter 23:

The Rejection and Punishment of the Jews

Rejection of Christ by the Jews: Tertullian argues that the rejection of Christ by the Jews was foretold in Isaiah and the Psalms. He cites Isaiah 1:7 to explain how the Jewish people, by rejecting Christ, brought desolation upon their own land and cities, leading to their eventual dispersion.

Connection to Irenaeus: Irenaeus, in Adversus Haereses IV.4.1, similarly argues that the destruction of Jerusalem and the dispersion of the Jews were prophesied as a result of their rejection of Christ. Both Tertullian and Irenaeus use Isaiah to show that the Jewish nation’s punishment was part of the Creator’s plan.

Irenaeus citation: "Isaiah foretold that the Jewish nation would be desolated for rejecting the Messiah, as we now see fulfilled in the destruction of Jerusalem."

Psalm 59: Dispersion of the Jews: Tertullian references Psalm 59:13, where David prays for the dispersion of the enemies of God. He interprets this as a prophecy of the Jewish people’s dispersion following their rejection of Christ.

Connection to Irenaeus: Irenaeus uses the same psalm in Adversus Haereses IV.30.1 to argue that the dispersion of the Jews was a divine judgment for their opposition to Christ. Both authors use this psalm to explain the Jewish diaspora as a fulfillment of prophecy.

Irenaeus citation: "The psalmist’s prayer for the dispersion of God’s enemies was fulfilled when the Jews were scattered after rejecting the Creator’s Christ."

Christ’s Crucifixion and Its Consequences: Tertullian further argues that the crucifixion of Christ was prophesied and that the Jews’ rejection of Him led to their eventual downfall. He connects this to Jeremiah 11:19 and Isaiah 50:11, showing how the Jewish leaders plotted against Christ, but their plans ultimately led to their own destruction.

Connection to Irenaeus: Irenaeus in Adversus Haereses IV.34.1 explains how the rejection and crucifixion of Christ fulfilled Old Testament prophecies, leading to the desolation of Jerusalem. Both Tertullian and Irenaeus emphasize the consequences of rejecting the Creator’s Christ.

Irenaeus citation: "The prophets foretold that the rejection of the Creator’s Christ would bring about the destruction of those who opposed Him, as we see in the fall of Jerusalem."

Summary of Specific Citations:

• Chapter 21: Tertullian’s use of Isaiah (42:4, 2:2) and Paul’s letters (Rom 10:15) to argue for the universality of Christ’s mission aligns with Irenaeus’s similar use of these texts (Adversus Haereses III.16.3, III.22.4). Both argue against Marcion’s division of Christ.
  Chapter 22: Tertullian’s argument that the apostles’ preaching fulfilled Old Testament prophecy (Isa. 52:7, Psalm 19:4) mirrors Irenaeus’s use of the same prophecies (Adversus Haereses III.13.1). They both argue that the apostles continued the Creator’s plan.
  Chapter 23: Tertullian’s use of Isaiah (1:7, 50:11) and the Psalms (59:13) to explain the rejection and dispersion of the Jews parallels Irenaeus’s interpretation of these prophecies (Adversus Haereses IV.4.1, IV.30.1). Both view the Jewish rejection of Christ as part of a prophesied divine plan.

Tertullian’s arguments in these chapters reflect his reliance on the same scriptural interpretations as Irenaeus, particularly in using the canonical Gospel of Luke and the letters of Paul to counter Marcion’s claims. Both writers share a unified theological framework that does not depend on Marcion’s alleged falsified texts but instead on the canonical tradition of the Church.

Chapter 24:

Tertullian’s Argument Regarding the Kingdom of God and the Afterlife

Earthly and Heavenly Promises: Tertullian begins by criticizing the Marcionite view of Christ’s promise of a purely heavenly and eternal kingdom, while contrasting it with the Jewish expectation of a restored earthly kingdom and Abraham's bosom (Luke 16:22-23). He mocks the idea that God, having taken away earthly blessings in anger, would now restore them in mercy. Tertullian insists that both earthly and heavenly promises come from the same Creator.

Connection to Irenaeus: Irenaeus makes a similar distinction between earthly and heavenly promises in Adversus Haereses V.32.1, where he emphasizes that both the material and spiritual blessings belong to the same Creator and are part of the divine economy. Like Tertullian, he contrasts Marcion’s rejection of the material world with the promises of both earthly and heavenly rewards made by the Creator.

Irenaeus citation: “The Creator promised both an earthly inheritance and a heavenly one, and in both the material and the spiritual He manifests His goodness.”
The Promise of the Heavenly Jerusalem: Tertullian references the promise of the heavenly Jerusalem, drawing from Paul's description in Galatians 4:26 and Revelation 21:2. He stresses that this heavenly city is the ultimate fulfillment of the Creator's promise, which includes both spiritual and material blessings for the saints after the resurrection.

Connection to Irenaeus: Irenaeus also refers to the heavenly Jerusalem in Adversus Haereses V.35.2, where he speaks of the final restoration of all things in the heavenly city after the resurrection. Both Irenaeus and Tertullian see the promise of the heavenly Jerusalem as part of the Creator’s plan, contrasting it with Marcion’s rejection of the material.
Irenaeus citation: “The heavenly Jerusalem, as foretold by John and Paul, is the culmination of the Creator’s promises, uniting the material and the spiritual in perfect harmony.”

The Reign of Christ for a Thousand Years: Tertullian emphasizes the reign of Christ for a thousand years in the heavenly city (Rev. 20:4-6). He interprets this as the fulfillment of the Creator's promise, with the saints being rewarded with spiritual abundance and resurrection.

Connection to Irenaeus: Irenaeus also emphasizes the millennial reign in Adversus Haereses V.33.4, where he interprets it as part of the Creator’s promise of earthly and heavenly blessings. Both argue against Marcion’s denial of a future earthly kingdom, focusing instead on the Creator’s plan for a new heaven and a new earth.

Irenaeus citation: “The millennial reign of Christ on earth is the promise of the Creator, who will reward the saints with both spiritual and material blessings after the resurrection.”
The Promise of Heaven and Earth: Tertullian stresses that the Creator’s promise includes both heaven and earth, citing the dual blessings promised to Jacob in Genesis 27:28 and 27:39, where Isaac blesses his sons with both the dew of heaven and the fatness of the earth. He interprets this as a model for understanding how the Creator offers both earthly and heavenly rewards.

Connection to Irenaeus: Irenaeus similarly uses the blessings of Isaac in Adversus Haereses IV.10.2, where he argues that the Creator’s plan includes both material and spiritual blessings. Both authors use the Old Testament blessings to support the idea that the same God provides for both heaven and earth.

Irenaeus citation: “The blessings given to Jacob and Esau, combining the dew of heaven and the fatness of the earth, show that the Creator offers both spiritual and material rewards to His people.”

Further Specific Citations of Reused Arguments:

Heavenly and Earthly Blessings through Christ: Tertullian uses Luke 12:31, “Seek first the kingdom of God, and these things will be added unto you,” to show that Christ’s promise includes both spiritual and earthly blessings. He contrasts this with the Marcionite view that Christ only offers heavenly rewards.

Connection to Irenaeus: Irenaeus also cites this passage in Adversus Haereses V.32.2, arguing that Christ’s teachings include both material and spiritual rewards, which are given by the Creator. Both writers emphasize the continuity between the promises of the Old Testament and Christ’s teachings.

Irenaeus citation: “Seek first the kingdom of God, and the other blessings will be added. Thus, Christ teaches that the Creator’s promises encompass both the material and the spiritual.”

Jacob’s Ladder as a Symbol of Heaven’s Access: Tertullian interprets Jacob’s dream of the ladder in Genesis 28:12-17 as a symbol of Christ being the way to heaven, with the angels ascending and descending as a metaphor for judgment. He points to Christ as the gateway to heaven, refuting Marcion’s idea of a different god offering heavenly access.

Connection to Irenaeus: Irenaeus similarly uses Jacob’s ladder in Adversus Haereses IV.20.2, interpreting it as a symbol of the connection between heaven and earth made possible by Christ. Both authors argue that the vision of Jacob prefigures Christ’s role as the bridge between the material and spiritual worlds.

Irenaeus citation: “The ladder in Jacob’s vision represents Christ, the mediator between heaven and earth, who makes access to the Father possible.”

Christ's Role in the Heavenly Kingdom: Tertullian interprets Amos 9:6, where God is said to build His ascension to heaven, as a prophecy of Christ’s role in bringing the saints into the heavenly kingdom. He emphasizes that this ascension is not for Christ alone but for all who follow Him.

Connection to Irenaeus: Irenaeus in Adversus Haereses V.36.3 also interprets the same passage as referring to Christ’s ascension and His role in leading the saints to heaven. Both see the fulfillment of this prophecy as part of the Creator’s plan to redeem humanity.

Irenaeus citation: “Christ’s ascension, foretold by Amos, is the fulfillment of the Creator’s promise to bring His people into the heavenly kingdom.”

Conclusion:

Chapter 24 of Adversus Marcionem shows Tertullian reusing key theological arguments found in Irenaeus’s Adversus Haereses. Both authors argue from the canonical Gospel of Luke, the letters of Paul, and Old Testament prophecy to refute Marcion's idea of a separate, higher god and to assert that the promises of the Creator include both earthly and heavenly blessings. Specific citations and examples include the promises to Jacob, the vision of Jacob’s ladder, and Christ’s role in fulfilling both material and spiritual blessings.

I see that this question continues to be not addressed:

StephenGoranson wrote: ↑Fri Sep 06, 2024 10:14 am If Tertullian used some arguments that Irenaeus used, does that, by itself, show they are wrong?

What am I supposed to say? When Goranson made his comment I was midway through Book 4. Surely at some point the volume is the argument. There has to be a threshold for reasonable people. When I double check my work if what I have culled stands, I've reached the reasonable threshold.

Scripture: Luke 4:18-19

Chapter 3

Scripture: Galatians 1:6-9

("The argument must be settled by an appeal to time, giving authority to that which will be found to be older, and establishing the falsification of that which will be shown to be later").
Irenaeus: Adversus Haereses 3.1.1 – Irenaeus frequently appeals to antiquity, arguing that the canonical gospels, including Luke, are older and thus more authentic than Marcion’s version.
Scripture: Luke 1:1-4

Tertullian: "Si enim id evangelium quod Lucae refertur penes nos... ipsum est quod Marcion per Antitheses suas arguit ut interpolatum"
("For if the gospel attributed to Luke, which we possess, is the same one Marcion attacks in his Antitheses as having been interpolated...").

Scripture: Luke 16:17

Tertullian: "Certe Antitheses non modo fatentur Marcionis, sed et praeferunt... quod Lucae refertur"

Scripture: Luke 6:40

Tertullian: "In quantum enim falsum corruptio est veri, in tantum praecedat necesse est veritas falsum"

("In attempting to correct it, he confirms both our earlier version and his later one").
Irenaeus: Adversus Haereses 1.27.4 – Irenaeus asserts that Marcion’s alterations confirm the existence of an unaltered earlier version.
Scripture: Galatians 1:11-12

Chapter 5

Tertullian: "In summa, si constat id verius quod prius, id prius quod et ab initio, id ab initio quod ab apostolis, pariter utique constabit id esse ab apostolis traditum quod apud ecclesias apostolorum fuerit sacrosanctum"
("In sum, if that which is earlier is more true, that which was from the beginning is earlier, and that which was from the beginning is from the apostles; it will be agreed that what was handed down by the apostles is that which has been held as sacred in the churches of the apostles").
Irenaeus: Adversus Haereses 3.1.1 – Irenaeus uses a similar argument regarding the apostolic origin of the canonical gospels, contending that the older gospel traditions were transmitted by the apostles and deviations, like Marcion’s alterations, are later corruptions.
Scripture: Luke 1:1-4

Tertullian: "Dico itaque apud illas, nec solas iam apostolicas, sed apud universas quae illis de societate sacramenti confoederantur, id evangelium Lucae ab initio editionis suae stare quod cum maxime tuemur, Marcionis vero plerisque nec notum, nullis autem notum ut non eadem damnat."
("I say, therefore, that among those churches, not only the apostolic ones but also all those united in the sacrament of faith, the Gospel of Luke has stood from the beginning; Marcion’s version is known to few, and none know it without condemning it").
Irenaeus: Adversus Haereses 3.11.7 – Irenaeus accuses Marcion of editing Luke’s gospel to suit his theological views, omitting material tying Jesus to the Old Testament prophets. Tertullian follows this by emphasizing Marcion's gospel's lesser known and condemned status.
Scripture: Luke 16:17

Tertullian: "Nam et Lucae digestum Paulo adscribere solent... Lucae autem, quod est secundum nos, adeo congruit regulae eorum ut cum illis apud ecclesias maneat, iam et Lucae constat integrum decucurrisse usque ad sacrilegium Marcionis."
("For Luke’s account is generally attributed to Paul... Luke’s gospel, which we hold, is so consistent with their rule that it remains in the churches, and it is clear that Luke’s gospel remained intact until Marcion’s sacrilege").
Irenaeus: Adversus Haereses 3.11.7 – Irenaeus asserts that Marcion corrupted Luke’s original gospel, which had been passed down intact by the apostles. Tertullian echoes this, emphasizing Luke's gospel’s integrity prior to Marcion's changes.
Scripture: Luke 24:44-45

Tertullian:
"Nam et Lucae digestum Paulo adscribere solent... Capit magistrorum videri quae discipuli promulgarint."
("For Luke’s account is generally attributed to Paul... The things which the disciples have promulgated seem to reflect their teachers").
Irenaeus: Adversus Haereses 3.1.1 – Irenaeus stresses apostolic authority in defending the canonical gospels. Tertullian similarly defends Luke’s gospel by linking it to Paul, reinforcing its apostolic foundation.

Scripture: Acts 16:10

Tertullian: "In quantum ergo emendasset quae fuissent emendanda, si fuissent corrupta, in tantum confirmavit non fuisse corrupta quae non putavit emendanda."
("Thus, in so far as Marcion would have corrected what needed to be corrected if it had been corrupt, he confirmed that what he did not think needed to be corrected was not corrupt").

Irenaeus: Adversus Haereses 3.11.7 – Irenaeus argues that Marcion’s alterations are evidence that the original gospel remained intact before his manipulations. Tertullian agrees, stating that Marcion’s failure to correct parts proves their integrity.
Scripture: John 17:17

Tertullian: "Denique emendavit quod corruptum existimavit. Sed nec hoc merito, quia non fuit corruptum."
("Finally, he corrected what he believed to be corrupt. But not rightly, because it was not corrupt").
Irenaeus: Adversus Haereses 3.11.7 – Irenaeus accuses Marcion of selectively modifying the original gospel. Tertullian follows this by asserting that Marcion’s edits were unnecessary as the original text of Luke was not corrupt.
Scripture: Galatians 1:11-12

Chapter 6

Tertullian: "Certe enim totum quod elaboravit etiam Antitheses praestruendo in hoc cogit, ut veteris et novi testamenti diversitatem constituat, proinde Christum suum a creatore separatum, ut dei alterius, ut alienum legis et prophetarum."
("Certainly, everything Marcion worked on, including his Antitheses, was intended to establish a division between the Old and New Testaments, so that his Christ would be separated from the Creator, as the Son of a different God, alien to the Law and the Prophets").
Irenaeus: Adversus Haereses 3.11.7 – Irenaeus argues that Marcion attempted to separate Christ from the Creator God by rejecting the Old Testament and its prophecies. Both Tertullian and Irenaeus assert that Marcion introduced a radical disjunction between the Old and New Testaments.
Scripture: Matthew 5:17-18

Tertullian: "Certe propterea contraria quaeque sententiae suae erasit, conspirantia cum creatore, quasi ab assertoribus eius intexta: competentia autem sententiae suae reservavit."

Irenaeus: Adversus Haereses 3.11.7 – Irenaeus accuses Marcion of selectively editing the Gospel of Luke to remove references connecting Jesus to the Creator. Both Tertullian and Irenaeus assert that Marcion manipulated the text to support his theological division between Christ and the Creator.
Scripture: Luke 4:17-21

Tertullian: "Ex his mihi probatio sufficit. Si enim id evangelium quod Lucae refertur penes nos ipsum est quod Marcion per Antitheses suas arguit ut interpolatum... non potuisset arguere nisi quod invenerat."
("From this, I derive sufficient proof. For if the gospel attributed to Luke, which we possess, is the same one that Marcion criticizes in his Antitheses as having been interpolated... then surely he could not have argued against it unless he had found it").
Irenaeus: Adversus Haereses 3.11.7 – Irenaeus also focuses on Marcion’s use of the Antitheses to justify his alterations to Luke's Gospel. Both argue that Marcion’s critique presupposes the existence of the original text, which he altered.
Scripture: Galatians 1:8

Tertullian: "Constituit Marcion alium esse Christum... quantam inter iustum et bonum, quantam inter legem et evangelium, quantam inter Iudaismum et Christianismum."
("Marcion established that there was a different Christ... as much difference as there is between justice and goodness, between law and gospel, between Judaism and Christianity").
Irenaeus: Adversus Haereses 3.25.3 – Irenaeus critiques Marcion’s dichotomy between the God of the Old Testament (justice) and the God of the New Testament (goodness). Tertullian’s language of division mirrors Irenaeus’s argument, particularly the contrast between the Law (justice) and the Gospel (goodness).
Scripture: Romans 3:31

Tertullian: "Christum creatoris pronuntiandum... si repraesentaverit promissiones eius, si restauraverit virtutes eius, si sententias reformaverit."
("Christ must be declared the Creator’s if He fulfills His promises, restores His virtues, and reforms His judgments").
Irenaeus: Adversus Haereses 3.11.7 – Irenaeus argues that Christ came to fulfill, not abolish, the Creator’s Law and the Prophets. Tertullian echoes Irenaeus’s defense of the continuity between the Old and New Testaments, asserting that Christ’s mission was to fulfill the Creator’s promises.
Scripture: Matthew 5:17

Chapter 7

Tertullian: "Anno quintodecimo principatus Tiberiani proponit eum descendisse in civitatem Galilaeae Capharnaum, utique de caelo creatoris, in quod de suo ante descenderat."
("In the fifteenth year of Tiberius' reign, he descended into the city of Capernaum in Galilee, surely from the Creator's heaven, the one he had previously descended into").
Irenaeus: Adversus Haereses 3.16.3 – Irenaeus emphasizes the fulfillment of Old Testament prophecies by Christ, in accordance with the Creator's plan. Tertullian echoes this by affirming Christ’s descent from "the Creator’s heaven."
Scripture: Luke 4:31

Tertullian: "Hoc enim Marcion ut additum erasit."
("For Marcion erased this as an addition").
Irenaeus: Adversus Haereses 3.11.7 – Irenaeus accuses Marcion of omitting passages from Luke that connect Christ with the Creator. Tertullian echoes this charge, asserting that Marcion erased passages that did not fit his theological agenda.
Scripture: Luke 4:32

Tertullian: "Certe enim totum quod elaboravit etiam Antitheses praestruendo in hoc cogit, ut veteris et novi testamenti diversitatem constituat."
("Certainly, everything Marcion worked on, including his Antitheses, was intended to establish a division between the Old and New Testaments").
Irenaeus: Adversus Haereses 3.16.2 – Although Irenaeus does not mention Marcion’s Antitheses explicitly, he critiques Marcion’s attempt to divide the Old and New Testaments. Tertullian builds on this critique by directly referencing Marcion’s Antitheses.
Scripture: Matthew 5:17

Tertullian: "Et loco et illuminationis opere secundum praedicationem occurrentibus Christo iam eum prophetatum incipimus agnoscere."
("By the place and the act of illumination, in accordance with prophecy, we begin to recognize Him as the foretold one").
Irenaeus: Adversus Haereses 3.11.7 – Irenaeus frequently stresses that Christ fulfilled the Old Testament prophecies. Tertullian follows this by arguing that Christ’s actions fulfilled the prophetic promises, recognizing Him as the one foretold by the prophets.
Scripture: Isaiah 9:1-2, Matthew 4:14-16

Tertullian: "Ecce venit in synagogam; certe ad oves perditas domus Israelis."
("Behold, He comes to the synagogue; surely to the lost sheep of the house of Israel").
Irenaeus: Adversus Haereses 3.21.3 – Irenaeus emphasizes that Christ’s mission was first to Israel, fulfilling the promises made to the patriarchs. Tertullian similarly argues that Christ’s mission to Israel demonstrates continuity with the Creator’s promises.
Scripture: Matthew 15:24, Matthew 10:6

Tertullian: "Stupebant autem omnes ad doctrinam eius. Quoniam, inquit, in potestate erat sermo eius, non quoniam adversus legem et prophetas docebat."
("And they were amazed at His teaching. For, He says, His words were spoken with authority, not because He taught against the Law and the Prophets").

Irenaeus: Adversus Haereses 3.11.7 – Irenaeus argues that Christ’s teachings did not contradict the Law and the Prophets but fulfilled them. Tertullian mirrors this by stressing that Christ’s authority did not stem from opposition to the Law but rather from its fulfillment.
Scripture: Matthew 7:28-29, Matthew 5:17

Tertullian: "Exclamat ibidem spiritus daemonis, Quid nobis et tibi est Iesu? venisti perdere nos: scio qui sis, sanctus dei."
("The demon there cries out, ‘What have we to do with You, Jesus? Have You come to destroy us? I know who You are, the Holy One of God’").
Irenaeus: Adversus Haereses 3.11.7 – Irenaeus emphasizes that the demons recognized Christ’s divine authority. Tertullian uses the same example of the demon acknowledging Christ as the "Holy One of God" to further undermine Marcion’s theology.
Scripture: Luke 4:33-34

Tertullian: "Atquin, inquis, increpuit illum Iesus. Plane, ut invidiosum... non ob mendacium increpitus."
("But, you will say, Jesus rebuked him. Clearly, He rebuked him not because of a lie, but because of envy").
Irenaeus: Adversus Haereses 3.10.3 – Irenaeus highlights Christ’s authority over demons. Tertullian builds on this by interpreting Christ’s rebuke of the demon not as a denial of the demon’s truth, but as a rejection of its malicious intent.
Scripture: Luke 4:35

Chapter 8

Tertullian: "Nazaraeus vocari habebat secundum prophetiam Christus creatoris... Nam et sumus de quibus scriptum est: Nazaraei exalbati sunt super nivem."
("Christ, the Creator’s, was supposed to be called a Nazarene according to prophecy... And we are those of whom it is written: ‘The Nazarites were whiter than snow’").
Irenaeus: Adversus Haereses 3.16.3 – Irenaeus frequently emphasizes the fulfillment of Old Testament prophecy in relation to Christ’s identity as the Messiah. Tertullian highlights the Nazarene prophecy, showing Christ’s fulfillment of the Creator’s promises, countering Marcion’s denial.
Scripture: Matthew 2:23

Tertullian: "Christum Marcionis oportuerat omne commercium eierasse etiam locorum familiarium Christi creatoris."
("Marcion’s Christ should have severed all association with locations familiar to the Creator’s Christ").
Irenaeus: Adversus Haereses 3.11.8 – Irenaeus critiques Marcion for disconnecting Christ from the Creator’s covenant with Israel. Tertullian expands this by emphasizing Marcion’s attempt to erase geographical ties, like Christ’s association with Nazareth.
Scripture: John 1:46

Tertullian: "Non possit phantasma credi qui contactum et quidem violentia plenum detentus et captus et ad praecipitium usque protractus admiserit."
("He cannot be believed to be a phantom if He admitted to being seized, held, and dragged to the cliff").
Irenaeus: Adversus Haereses 3.22.4 – Irenaeus critiques Marcion’s docetic tendencies, denying Christ’s physicality. Tertullian similarly argues that Christ’s physical interactions, like being seized and dragged, prove His real, physical body, countering Marcion’s phantom-like Christ.
Scripture: Luke 4:29

Tertullian:"Ipse igitur est Christus Esaiae, remediator valetudinum."
("He is therefore the Christ of Isaiah, the healer of infirmities").

Scripture: Isaiah 53:4

Tertullian: "Proinde enim Christus ab hominibus, non a spiritibus immundis, volebat se filium dei agnosci."
("For Christ wanted to be recognized as the Son of God by men, not by unclean spirits").
Irenaeus: Adversus Haereses 3.11.7 – Irenaeus emphasizes that Christ’s true recognition comes from fulfilling the Creator’s promises, not from demonic testimony. Tertullian builds on this by noting that Christ rejects the acknowledgment of unclean spirits.
Scripture: Luke 4:35

Tertullian: "Oportet me, inquit, et aliis civitatibus annuntiare regnum dei."
("He says, 'I must preach the kingdom of God in other cities as well'").
Irenaeus: Adversus Haereses 3.11.8 – Irenaeus emphasizes that Christ’s mission began with Israel but extended to the nations. Tertullian reflects this view by focusing on Christ’s preaching of the kingdom to other cities, fulfilling the Creator’s promise to Israel and the nations.
Scripture: Luke 4:43

Tertullian: "Et daemonia timore utique cedebant... filium confitebantur."
("And the demons certainly fled in fear... confessing Him as the Son").

Scripture: Luke 4:41

Chapter 9

Tertullian: Tertullian argues that if Marcion’s Christ were truly a phantom, He would not have been affected by physical contact. Tertullian opposes Marcion’s docetic Christology, which portrays Christ as not having a real body.
Irenaeus: Adversus Haereses 3.22 – Irenaeus refutes the idea that Christ was merely a phantom and emphasizes that Christ's incarnation and suffering were real. Both Tertullian and Irenaeus argue against docetism, which denies Christ's true humanity.
Scripture: Luke 5:12-13

Tertullian: Tertullian highlights Jesus's healing of the leper as fulfilling the law. He emphasizes how Jesus instructed the healed leper to go to the priests as a testimony, proving His continuity with the Creator’s commands. He criticizes Marcion for not acknowledging that Christ came to fulfill, not abolish, the law.
Irenaeus: Adversus Haereses 4.9 – Irenaeus similarly argues that Christ fulfilled the law, particularly in relation to Old Testament prefigurations. Tertullian builds upon this argument, using the specific example of healing the leper to show how Christ's actions align with the Creator's law.
Scripture: Leviticus 14:2-32, Matthew 5:17

Tertullian: Tertullian claims that Jesus fulfilled Old Testament prophecies by healing and restoring the unclean, demonstrating His fulfillment of the Creator's promises.
Irenaeus: Adversus Haereses 4.10 – Irenaeus frequently uses Old Testament prophecy to demonstrate Christ’s legitimacy, particularly against Marcion's argument that the Old Testament God is different from the New Testament God. Both authors argue that Christ fulfilled prophecy and established continuity with the law and prophets.
Scripture: Isaiah 53:4, Matthew 11:5

Tertullian: Tertullian accuses Marcion of erasing parts of the gospel that demonstrate Jesus fulfilling the law, particularly references to the Old Testament.
Irenaeus: Adversus Haereses 3.11 – Irenaeus accuses Marcion of selectively altering the texts to fit his theology, including omitting parts of Luke that reference Christ’s fulfillment of the law. Both Tertullian and Irenaeus criticize Marcion for his selective editing of scripture.
Scripture: Luke 4:16-21

Chapter 10

Jesus's Healing of the Paralytic

Tertullian:
“Curatur et paralyticus, et quidem in coetu, spectante populo. Videbit enim, inquit Esaias, populus sublimitatem domini et gloriam dei."
("The paralytic is healed, indeed in a gathering, before the people. For Isaiah says, 'The people will see the glory of the Lord and the majesty of God.'")

Irenaeus:
Adversus Haereses 3.10 – Irenaeus emphasizes Christ as the fulfillment of Old Testament prophecies, including healing the sick. While Irenaeus does not mention Isaiah directly here, the emphasis on Jesus as the fulfillment of prophecy aligns with Irenaeus’s broader theme.

Scripture:
Isaiah 35:5-6, Mark 2:1-12

Forgiveness of Sins by Christ

Tertullian:
“Christum recognosce apud eundem prophetam: Quoniam, inquit, in plurimis dimittet delicta eorum, et delicta nostra ipse aufert."
("Recognize Christ in the same prophet: 'For He will forgive the sins of many and He will take away our sins.'")

Irenaeus:
Adversus Haereses 3.18 – Irenaeus discusses Christ’s authority to forgive sins, asserting Jesus's divinity. Both Tertullian and Irenaeus argue against Marcion’s denial of Christ's ability to forgive sins as the Son of God.

Scripture:
Isaiah 53:4-5, Mark 2:5

Connection to Old Testament Figures (e.g., David, Achab)

Tertullian:
“Lego et Nathan prophetam agnoscenti David delictum suum in Uriam dixisse, Et dominus circumduxit delictum tuum et non morieris."
("I read that the prophet Nathan said to David after he acknowledged his sin with Uriah, 'The Lord has taken away your sin, and you will not die.'")

Irenaeus:
Adversus Haereses 4.16 – Irenaeus uses Old Testament figures, like David, to show the continuity between God’s mercy in the Old Testament and Christ's role in the New Testament. Tertullian mirrors this by referencing David to demonstrate Christ’s role in forgiving sins.

Scripture:
2 Samuel 12:13

Jesus as the "Son of Man"

Tertullian:
“De filio hominis duplex est nostra praescriptio... neque mentiri posse Christum, ut se filium hominis pronuntiaret si non vere erat."
("Our argument concerning the Son of Man is twofold... Christ could not lie by declaring Himself the Son of Man if He truly wasn’t.")

Irenaeus:
Adversus Haereses 3.19 – Irenaeus uses the title "Son of Man" to assert Jesus's real humanity, countering docetic claims. Tertullian follows this line by emphasizing that Jesus truly had human nature, as seen in His self-identification as the "Son of Man."

Scripture:
Daniel 7:13, Luke 5:24

Tertullian: “Ex matre autem virgine quia non ex patre homine, hic erit Christus Esaiae quem concepturam virginem praedicat."
("From a virgin mother, not a human father, this is the Christ whom Isaiah predicted the virgin would conceive.")
Irenaeus: Adversus Haereses 3.21 – Irenaeus frequently emphasizes the prophecy of the virgin birth from Isaiah (Isaiah 7:14) as key evidence for the incarnation of Christ. Tertullian similarly uses the prophecy to refute Marcion’s denial of the incarnation.
Scripture: Isaiah 7:14, Matthew 1:23

Tertullian: “Phantasma enim inquinari non posset... Phantasma enim inquinari non posset." ("A phantom could not be defiled... A phantom could not be defiled.")
Irenaeus: Adversus Haereses 4.33 – Irenaeus challenges Marcion’s idea that Christ was a phantom. Tertullian uses a similar argument to refute Marcion’s docetic Christology, emphasizing that Christ’s body was real and not an illusion.
Scripture: Luke 24:39

Tertullian: “Hoc dixi sufficere potuisse de nominatione prophetica circa filium hominis..."
("I said this could have sufficed regarding the prophetic naming of the Son of Man...")
Irenaeus: Adversus Haereses 3.22 – Irenaeus frequently refers to Christ’s fulfillment of the prophecy about the "Son of Man" in Daniel, who would judge the nations. Tertullian similarly uses this prophecy to assert Christ’s identity as the Son of God.
Scripture: Daniel 7:13-14, John 5:27

Chapter 12

The Inclusion of a Tax Collector (Publicanus)

Tertullian: "Publicanum adlectum a domino in argumentum deducit, quasi ab adversario legis adlectum, extraneum legis et Iudaismi profanum."
("He draws a tax collector, called by the Lord, as an argument, as if he were called by an adversary of the law, one who is foreign and profane to the law and Judaism.")
Irenaeus: Adversus Haereses 4.3 – Irenaeus discusses how Christ calls people outside the Jewish law, demonstrating His inclusive mission. Both authors emphasize that Christ’s calling of outsiders, like tax collectors, challenges Marcion’s exclusivity between the Creator and Jesus.
Scripture: Luke 5:27-32

The Role of Jesus as a Healer and Physician

Connection with John the Baptist

Tertullian: "Ut demonstrem et Ioannem Christo et Christum Ioanni convenire, utique prophetae creatoris, qua Christum creatoris."
("So that I may show that both John and Christ are connected, certainly a prophet of the Creator and Christ of the Creator.")
Irenaeus: Adversus Haereses 3.10 – Irenaeus emphasizes John the Baptist as the precursor to Christ, fulfilling Old Testament prophecy.

The New and Old Wine Metaphor

Tertullian: "Nam et vinum novum is non committit in veteres utres qui et veteres utres non habuerit, et novum additamentum nemo inicit veteri vestimento." ("For no one puts new wine into old wineskins, nor does anyone put a new patch on an old garment.")
Irenaeus: Adversus Haereses 4.9 – Irenaeus discusses the relationship between the old and new covenants, showing that Christ fulfills rather than abolishes the law. Tertullian uses the same metaphor of new wine in old wineskins to show the harmony between the law and the gospel.
Scripture: Luke 5:36-39

The Separation of Law and Gospel

Tertullian: "Itaque si in hoc dirigebat similitudinem, ut ostenderet se evangelii novitatem separare a legis vetustate."
("So if He directed the parable to show the newness of the gospel as separate from the oldness of the law.")

Changing Simon’s Name to Peter

Tertullian: "Mutat et Petro nomen de Simone, quia et creator Abrahae et Sarae et Auseae nomina reformavit."

Irenaeus: Adversus Haereses 3.16 – Irenaeus compares the renaming of Simon to Peter with the Creator changing names in the Old Testament, such as Abram to Abraham. Tertullian makes the same comparison, reinforcing the continuity between the Old and New Testaments.
Scripture: Genesis 17:5, Genesis 17:15, Hosea 1:4, Matthew 16:18

The Multitude Coming from Various Regions

Tertullian: "Conveniunt a Tyro et ex aliis regionibus multitudo etiam transmarina." ("A multitude comes from Tyre and from other regions, even across the sea.")
Irenaeus: Adversus Haereses 4.23 – Irenaeus highlights the universality of Christ’s mission, mentioning people gathering from distant lands. Tertullian uses similar language to refer to Old Testament prophecies, such as Isaiah 43:6, where people come from afar. Both argue that this gathering fulfills prophecy.
Scripture: Isaiah 43:6, Luke 6:17-19

Christ as the Fulfillment of the Prophets

Tertullian: "Hic erit Christus non prophetarum?" ("Is this not the Christ foretold by the prophets?")

Irenaeus: Adversus Haereses 3.9 – Irenaeus refers to prophecies in Isaiah about the Messiah bringing people from distant lands. Tertullian uses the same prophecy to argue that Christ’s mission was foretold by the Creator. Both authors emphasize Christ's role in fulfilling the prophecies of the Old Testament.
Scripture: Isaiah 43:5-6, Matthew 8:11

Secret Alias wrote: ↑Fri Sep 06, 2024 9:47 am To provide specific evidence that Tertullian was reusing or heavily influenced by Irenaeus’s treatise in his arguments against Marcion—particularly regarding their use of the canonical Gospel of Luke and assumptions about Marcion’s "falsified Luke"—let’s examine several key points of similarity between their works. These parallels suggest that Tertullian may have adapted Irenaeus’s arguments rather than developing them independently.

I may be missing the point, but: so what? It's clear that the early heresioligists had access to earlier works and worked from them. Tertullian writes in "Against the Valentinians", Chap 5, how he has read the works of "holy and excellent men" who had written refutations against the heresiarchs and names them:
https://www.earlychristianwritings.com/ ... ian14.html


Irenaeus refers to an earlier work by Justin Martyr against Marcion:
https://www.earlychristianwritings.com/ ... book4.html


Justin Martyr himself refers to a work he composed -- while Marcion was still alive -- against the heretics of his time:
https://www.earlychristianwritings.com/ ... ology.html


The options are:

1. Tertullian had a copy of Marcion's canon in front of him when writing his refutation
2. Tertullian had read Marcion's canon but was working from memory
3. Tertullian hadn't read Marcion's canon but was working from previous works by Irenaeus and others

Does it really matter which one of those options are correct? Tertullian claims he is working from authors who were contemporaries or near-contemporaries to the heresiarchs. Taking from one source is called "plagiarism". Taking from many sources is called "research". So does it even matter if Tertullian hadn't read Marcion's works for himself? The question is (at least for me): what did Tertullian get wrong, and how do we know he got it wrong?

Does it really matter which one of those options are correct?

One notable difference between (1) and the other two options is that (1) make more plausible that Tertullian is preserving information about the order of things in Marcion's gospel, while under (2) and (3) it would be unreasonable to assume that Tertullian isn't just giving items in Luke's order (given that there is at most one significant deviation from Luke's order), since under (2) and (3) Tertullian would be able to reference Luke for information on order but not Marcion's gospel.

Also again under (1) it would be more plausible to assume that Tertullian had not ever (or rarely) been confused with any readings that are not necessarily in Marcion's gospel (many claim that Tertullian was reading directly from Marcion's gospel and no other text), while some confusion would be expected under (2) and (3).

What you seem to be giving insufficient credit to is how extremely conservative (by your own standards of open mindedness on these options) prior scholarship has been in terms of giving high credence to Tertullian's Against Marcion book 4 and all its details, including its order, based on the assumption that it is a first hand report being produced in close tandem with a reading of Marcion's gospel set out before him.

With these kinds of considerations, it could be the difference of moving from a default position of Tertullian's accuracy (which is what most scholarship takes for granted) to giving no credence to Tertullian regarding order and accepting Tertullian's statements only when there is more explicit or implicit indication that Marcionites used a reading (which is an approach that I tried to follow).

You make some compelling points.

But it would be nice if you could sift through this to find out which points were truly convincing.

To kill something you have to actually kill something. Killing something is a difficult process.
