communicated by the Apostles” directly from our Synoptic Gospels, but from a εὐαγγέλιον τοῦ κυρίου which presented a text of Matthew enriched by additions from Luke. The Diatessaron of Tatian (§ 30, 10) shows that soon after this the gospel of John, which was not regarded by Justin or the author of the Didache as a source for the evangelical history, although there are not wanting in both manifold references to it, came to be regarded as a work to be read in combination with these. It was only after a New Testament Canon had been in the Old Catholic Age gradually established, and from the vast multitude of books on gospel history, which even Luke had found existing (i. 1) and which had been multiplied to an almost incalculable extent both in the interests of heresy and of church doctrine, our four gospels were universally recognised as alone affording authentic information of the life and doctrines of the Lord, that the eclectic gospels hitherto in use had more and more withdrawn from them the favour of the church. =Tatian’s Diatessaron= maintained its place longest in the Syrian Church. Theodoret, † A.D. 457, testifies that in his diocese he had found and caused to be put away about two hundred copies. Aphraates (about A.D. 340, § 47, 13) still used it as the text of his homilies. At the time of publication of the _Doctrina Addæi_ (§ 32, 6) it was still used in the church of Edessa, and Ephraim Syrus in A.D. 360 refers to a commentary in the form of scholia on it in an Armenian translation, in which the passages commented on are literally reproduced, Theodoret’s charge against it of cutting out passages referring to the descent of Christ after the flesh from David, especially the genealogies of Matthew and Luke, is confirmed by these portions thus preserved. Otherwise however, it is free from heretical alterations, though not wholly without apocryphal additions. All the four gospels are in brief summary so skilfully wrought into one another that no joining is ever visible. What cannot be incorporated is simply left out, and the whole historical and doctrinal material is distributed over the one working year of the synoptists.
