If we go on to examine the discourse and narrative material, additional to that of Mark, which is found in Matthew and Luke, a similar result appears. The same standpoint is regulative throughout, showing that the additions do not consist of oral or written traditional material which has been worked into the Marcan plan, but of a literary development of certain fundamental ideas and suggestions found in the first author. These developments, as is shown by the accounts of the Sermon on the Mount and the charge to the Twelve, are not carried as far in Luke as in Matthew. The additional material in the latter seems indeed to be worked up from suggestions in the former. Luke thus forms the transition stage between Mark and Matthew. The Marcan hypothesis, accordingly, now takes on the following form. Our knowledge of the Gospel history does not rest upon any basis of tradition, but only upon three literary works. Two of these are not independent, being merely expansions of the first, and the third, Matthew, is also dependent upon the second. Consequently there is no tradition of the Gospel history, but only a single _literary source_. But, if so, who is to assure us that this Gospel history, with its assertion of the Messiahship of Jesus, was already a matter of common knowledge before it was fixed in writing, and did not first become known in a literary form? In the latter case, one man would have created out of general ideas the definite historical tradition in which these ideas are embodied. The only thing that could be set against this literary possibility, as a historical counter‐possibility, would be a proof that at the period when the Gospel history is supposed to take place a Messianic expectation really existed among the Jews, so that a man who claimed to be the Messiah and was recognised as such, as Mark represents Jesus to have been, would be historically conceivable. This presupposition had hitherto been unanimously accepted by all writers, no matter how much opposed in other respects. They were all satisfied “that before the appearance of Jesus the expectation of a Messiah prevailed among the Jews”; and were even able to explain its precise character.
