authority of his own Gospel.(1) We have shown(2) how unwarrantable it is to affirm from such data that Marcion knew, and deliberately repudiated, the four canonical Gospels. The Fathers, with uncritical haste and zeal, assumed that the Gospels adopted by the Church at the close of the second and beginning of the third centuries must equally have been invested with canonical authority from the first, and Tertullian took it for granted that Marcion, of whom he knew very little, must have actually rejected the four Gospels of his own Canon. Even Canon Westcott admits that: "it is uncertain whether Tertullian in the passage quoted speaks from a knowledge of what Marcion may have written on the subject, or simply from his own point of sight."(3) There is not the slightest evidence that Marcion knew the fourth Gospel,(4) and if he did, it is perfectly inexplicable that he did not adopt it as peculiarly favourable to his own views.(5) If he was acquainted with the work and, nevertheless, rejected it as false and adulterated, his testimony is obviously opposed to the Apostolic origin and historical accuracy of the fourth Gospel, and the critical acumen which he exhibited in his selection of the Pauline Epistles renders his judgment of greater weight than that of most of the Fathers. We have now reached an epoch when no evidence regarding the fourth Gospel can have much weight, {372} and the remaining witnesses need not detain us long. "We have discussed at length the Diatessaron of Tatian,(1) and shown that whilst there is no evidence that it was based upon our four Gospels, there is reason to believe that it may have been identical with the Gospel according to the Hebrews, by which name, as Epiphanius(2) states, it was actually called. We have only now briefly to refer to the address to the Greeks [------], and to ascertain what testimony it bears regarding the fourth Gospel. It was composed after the death of Justin, and scarcely dates earlier than the beginning of the last quarter of the second century. No Gospel and no work of the New Testament is mentioned in this composition, but Tischendorf(3) and others point out one or two supposed references to passages in the fourth Gospel. The first of these in order, is one indicated by Canon Westcott,(4) but to which Tischendorf does not call attention: "God was in the beginning, but we have learned that the beginning is the power of Reason [------]. For the Lord of the Universe [------] being himself the substance [------] of all, in that creation had not been accomplished was alone, but inasmuch as he was all power, and himself the substance of things visible and invisible, all things were with him [------]. With him by means of rational power the Reason [------] itself also which was in him subsisted. But by the will of his simplicity, Reason [------] springs forth; but the Reason [------] not {373}
