For those interested, here are some of Justin's Trypho's challenges to Justin over the Christ found in the Scriptures:
Prove from Scriptures that Christ had to be crucified:
And when I had ceased, Trypho said, "These and such like Scriptures, sir, compel us to wait for Him who, as Son of man, receives from the Ancient of days the everlasting kingdom. But this so-called Christ of yours was dishonourable and inglorious, so much so that the last curse contained in the law of God fell on him, for he was crucified."
Then I replied to him, "If, sirs, it were not said by the Scriptures which I have already quoted...
...
Then he replied, "Let these things be so as you say--namely, that it was foretold Christ would suffer, and be called a stone; and after His first appearance, in which it had been announced He would suffer, would come in glory, and be Judge finally of all, and eternal King and Priest. Now show if this man be He of whom these prophecies were made."
And I said, "As you wish, Trypho, I shall come to these proofs which you seek in the fitting place; but now you will permit me first to recount the prophecies...
...
And Trypho said, "Sir, it were good for us if we obeyed our teachers, who laid down a law that we should have no intercourse with any of you, and that we should not have even any communication with you on these questions. For you utter many blasphemies, in that you seek to persuade us that this crucified man was with Moses and Aaron, and spoke to them in the pillar of the cloud; then that he became man, was crucified, and ascended up to heaven, and comes again to earth, and ought to be worshipped."
Then I answered, "I know that, as the word of God says, this great wisdom of God, the Maker of all things, and the Almighty, is hid from you. Wherefore, in sympathy with you, I am striving to the utmost that you may understand these matters which to you are paradoxical; but if not, that I myself may be innocent in the day of judgment.
Prove from Scriptures that the man who was crucified and ascended to heaven is the Christ of God:
And Trypho replied, "Now, then, render us the proof that this man who you say was crucified and ascended into heaven is the Christ of God. For you have sufficiently proved by means of the Scriptures previously quoted by you, that it is declared in the Scriptures that Christ must suffer, and come again with glory, and receive the eternal kingdom over all the nations, every kingdom being made subject to Him: now show us that this man is He."
Prove from Scriptures that this Christ pre-existed as God and then chose to be born as a man:
And Trypho said, "We have heard what you think of these matters. Resume the discourse where you left off, and bring it to an end. For some of it appears to me to be paradoxical, and wholly incapable of proof. For when you say that this Christ existed as God before the ages, then that He submitted to be born and become man, yet that He is not man of man, this[assertion] appears to me to be not merely paradoxical, but also foolish."
Prove that the spirit of Elijah was in John the Baptist:
And Trypho said, "This statement also seems to me paradoxical; namely, that the prophetic Spirit of God, who was in Elijah, was also in John."
Prove that the Scriptures say that Christ submitted to be born of a Virgin:
And Trypho said, "You seem to me to have come out of a great conflict with many persons about all the points we have been searching into, and therefore quite ready to return answers to all questions put to you. Answer me then, first, how you can show that there is another God besides the Maker of all things; and then you will show,[further], that He submitted to be born of the Virgin."
...
And Trypho said, "This point has been proved to me forcibly, and by many arguments, my friend. It remains, then, to prove that He submitted to become man by the Virgin, according to the will of His Father; and to be crucified, and to die. Prove also clearly, that after this He rose again and ascended to heaven." I answered, "This, too, has been already demonstrated by me in the previously quoted words of the prophecies, my friends...
...
And Trypho answered, "The Scripture has not, 'Behold, the virgin shall conceive, and bear a son,' but, 'Behold, the young woman shall conceive, and bear a son,' and so on, as you quoted. But the whole prophecy refers to Hezekiah, and it is proved that it was fulfilled in him, according to the terms of this prophecy. Moreover, in the fables of those who are called Greeks, it is written that Perseus was begotten of Danae, who was a virgin; he who was called among them Zeus having descended on her in the form of a golden shower. And you ought to feel ashamed when you make assertions similar to theirs, and rather[should] say that this Jesus was born man of men. And if you prove from the Scriptures that He is the Christ, and that on account of having led a life conformed to the law, and perfect, He deserved the honour of being elected to be Christ,[it is well]; but do not venture to tell monstrous phenomena, lest you be convicted of talking foolishly like the Greeks."
Prove from Scriptures that God endured to be born and become man:
And Trypho said, "You endeavour to prove an incredible and well-nigh impossible thing;[namely], that God endured to be born and become man."
"If I undertook," said I, "to prove this by doctrines or arguments of man, you should not bear with me. But if I quote frequently Scriptures, and so many of them, referring to this point, and ask you to comprehend them, you are hard-hearted in the recognition of the mind and will of God
Prove that some of the Scriptures have been completely cancelled:
Here Trypho remarked, "We ask you first of all to tell us some of the Scriptures which you allege have been completely cancelled."
Prove that the Psalm of David refer to the Christian's Christ:
Then Trypho said, "We know that you quoted these because we asked you. But it does not appear to me that this Psalm which you quoted last from the words of David refers to any other than the Father and Maker of the heavens and earth. You, however, asserted that it referred to Him who suffered, whom you also are eagerly endeavouring to prove to be Christ."
Prove using the Scriptures that the angels revolted from God:
On this, Trypho, who was somewhat angry, but respected the Scriptures, as was manifest from his countenance, said to me, "The utterances of God are holy, but your expositions are mere contrivances, as is plain from what has been explained by you; nay, even blasphemies, for you assert that angels sinned and revolted from God."
Prove that Isaiah shows Christ to be pre-existent:
Hereupon Trypho, after I had spoken these words, said, "Do not now suppose that I am endeavouring, by asking what I do ask, to overturn the statements you have made; but I wish to receive information respecting those very points about which I now inquire. Tell me, then, how, when the Scripture asserts by Isaiah, 'There shall come forth a rod from the root of Jesse; and a flower shall grow up from the root of Jesse; and the Spirit of God shall rest upon Him, the spirit of wisdom and understanding, the spirit of counsel and might, the spirit of knowledge and piety: and the spirit of the fear of the Lord shall fill Him:' (now you admitted to me," continued he, "that this referred to Christ, and you maintain Him to be pre-existent God, and having become incarnate by God's will, to be born man by the Virgin:) how He can be demonstrated to have been pre-existent, who is filled with the powers of the Holy Ghost, which the Scripture by Isaiah enumerates, as if He were in lack of them?"
Then I replied, "You have inquired most discreetly and most prudently, for truly there does seem to be a difficulty; but listen to what I say, that you may perceive the reason of this also. The Scripture says that these enumerated powers of the Spirit have come on Him...
Prove using Scriptures that the Christ was to suffer the suffering cursed in the Law:
Then Trypho remarked, "Be assured that all our nation waits for Christ; and we admit that all the Scriptures which you have quoted refer to Him. Moreover, I do also admit that the name of Jesus, by which the the son of Nave (Nun) was called, has inclined me very strongly to adopt this view. But whether Christ should be so shamefully crucified, this we are in doubt about. For whosoever is crucified is said in the law to be accursed, so that I am exceedingly incredulous on this point. It is quite clear, indeed, that the Scriptures announce that Christ had to suffer; but we wish to learn if you can prove it to us whether it was by the suffering cursed in the law."
I replied to him, "If Christ was not to suffer, and the prophets had not foretold that He would be led to death on account of the sins of the people...
