The comparison shows Wendling's analysis to be much more complex than von Soden's. This results from his separation of his groundwork into two strands. It also shows that Wendling assigns considerably more to M1 and M2 than von Soden to his Petrine source. This Wendling can afford to do, since he supposes two documents instead of one. The matter assigned by von Soden to the Petrine source is in part assigned by Wendling to M1 and in part to M2. E.g., i, 4-11, is assigned by von Soden to the Petrine source, and by Wendling to M2; but i, 16-39, is assigned to the Petrine source, and (with the exception of two parts of verses) to M1. The passage ii, 1-28, is assigned by von Soden to the Petrine source, by Wendling to M1 (again with exception of a few parts of verses). Of the one hundred and seventy-seven verses assigned by von Soden to his Petrine source, up to and including xiii, 37 (after which he so assigns nothing), Wendling assigns about one hundred and twenty-four to his M1, and only ten to M2. Tho he assigns some verses to M1 which von Soden does not give to the Petrine source, and omits some (assigning them to the redactor) which von Soden does so assign, up to xiii, 37, the M1 of Wendling agrees very closely with the Petrine source of von Soden. The material assigned to M1 and M2 after xiii, 37, is about equally divided between them. Wendling makes no claims for the Petrine origin of his M1 or M2, but after these are subtracted from the whole Gospel there is a smaller amount left for the work of his redactor than remains after the Petrine source is subtracted. Since Wendling distinguishes between two sources and the work of the redactor, and von Soden only between the Petrine tradition and other matter, this result also is what would be expected. The relatively great agreement of the results of these two investigations seems to prove that it is possible to distinguish an earlier and a later tradition in the Gospel. Beyond this, the difference between von Soden and Wendling is that the former makes no assertions concerning the identity of the final editor with the writer who recorded the Petrine tradition, while the latter asserts that the redactor is quite another person than the writer of either M1 or M2. Is this latter position of Wendling's susceptible of proof or disproof?
