This view continued to prevail, almost without question or examination, till towards the end of the eighteenth century, when Biblical criticism began to exhibit the earnestness and activity which have ever since more or less characterized it. Semler first abandoned the prevalent tradition, and, after analyzing the evidence, he concluded that Marcion's Gospel and Luke's were different versions of an earlier work,(3) and that the so-called heretical Gospel was one of the numerous Gospels from amongst which the Canonical had been selected by the Church.(4) Griesbach about the same time also rejected the ruling opinion, and denied the close relationship usually asserted to exist between the two Gospels.(5) Loffler(6) and Corrodi(7) strongly supported Sender's {83} conclusion, that Marcion was no mere falsifier of Luke's Gospel, and J. E. C. Schmidt(1) went still further, and asserted that Marcion's Gospel was the genuine Luke, and our actual Gospel a later version of it with alterations and additions. Eichhorn,(2) after a fuller and more exhaustive examination, adopted similar views; he repudiated the statements of Tertullian regarding Marcion's Gospel as utterly untrustworthy, asserting that he had not that work itself before him at all, and he maintained that Marcion's Gospel was the more original text and one of the sources of Luke. Bolten,(3) Bertholdt,(4) Schleiermacher,(5) and D. Schulz(6) likewise maintained that Marcion's Gospel was by no means a mutilated version of Luke, but, on the contrary, an independent original Gospel A similar conclusion was arrived at by Gieseler,(7) but later, after Hahn's criticism, he abandoned it, and adopted the opinion that Marcion's Gospel was constructed out of Luke.(8) On the other hand, the traditional view was maintained by Storr,(9) Arneth,(10) Hug,(11) Neander,(12) and Gratz,(13) although with little originality of investigation or argument; and {84} Paulus(1) sought to reconcile both views by admitting that Marcion had before him the Gospel of Luke, but denying that he mutilated it, arguing that Tertullian did not base his arguments on the actual Gospel of Marcion, but upon his work, the "Antitheses." Hahn,(2) however, undertook a more exhaustive examination of the problem, attempting to reconstruct the text of Marcion's Gospel(3) from the statements of Tertullian and Epiphanius, and he came to the conclusion that the work was a mere version, with omissions and alterations made by the Heresiarch in the interest of his system, of the third Canonical Gospel. Olshausen(4) arrived at the same result, and with more or less of modification but no detailed argument, similar opinions were expressed by Credner,(5) De Wette,(6) and others.(7) Not satisfied, however, with the method and results of {85}
