It looks to me that Tertullian had Marcion to say Jesus' disciples composed gMarcion. And Paul found that gospel:When Marcion complains that apostles are suspected (for their prevarication and dissimulation) of having even depraved the gospel, he thereby accuses Christ, by accusing those whom Christ chose. If, then, the apostles, who are censured simply for inconsistency of walk, composed the [Marcionite?] Gospel in a pure form, but false apostles interpolated their true record [in order to compose the other gospels?]; and if our own copies have been made from these, where will that genuine text of the apostle's writings be found which has not suffered adulteration? [Tertullian thought the Marcionite gospel should show at the core of the other gospels?] Which was it that enlightened Paul, and through him Luke? It is either completely blotted out, as if by some deluge--being obliterated by the inundation of falsifiers--in which case even Marcion does not possess the true Gospel; or else, is that very edition which Marcion alone possesses the true one, that is, of the apostles? AM IV, III
However, for Tertullian, and according to Marcion, other apostles (the false ones) interpolated it (in order to compose the other gospels, such as gLuke, gMatthew & gJohn). But if it is the case, these other gospels should look like gMarcion plus interpolations.... that Gospel which St. Paul found in existence, to which he yielded his belief, and with which he so earnestly wished his own to agree, that he actually on that account went up to Jerusalem to know and consult the apostles, "lest he should run, or had been running in vain;" in other words, that the faith which he had learned, and the gospel which he was preaching, might be in accordance with theirs. Then, at last, having conferred with the (primitive) authors, and having agreed with them touching the rule of faith, they joined their hands in fellowship, and divided their labours thenceforth in the office of preaching the gospel, so that they were to go to the Jews, and St. Paul to the Jews and the Gentiles. AM, IV, II
That's certainly can be argued for gLuke, but not for the others. And Tertullian emphasized the latter point ("completely blotted out" ... "obliterated")
Unfortunately, we don't know for certain if Tertullian knew what Marcion complained about or said, because the twosome did not live in the same generation. But if Tertullian knew, that would be from oral tradition (only one intermediary would be necessary, being young in the times of Marcion and old in the times of Tertullian). Otherwise that would only be a literary device by Tertullian in order to make points against gMarcion.
But the argument has some merit: If gMarcion was the first gospel, then the others should look drawn from it.
That may be the case for gLuke, but not for the others. As a matter of fact, it is gMark which seems to have been the one which other gospels drew from.
And it looks here that Marcion knew about these other gospels.Well, but Marcion, finding the Epistle of Paul to the Galatians (wherein he rebukes even apostles) for "not walking uprightly according to the truth of the gospel," as well as accuses certain false apostles of perverting the gospel of Christ), labours very hard to destroy the character of those Gospels which are published as genuine and under the name of apostles
Any comments?
