the people of God, the children of the faith of Abraham. From the Old Testament he proves the divinity of the person and doctrine of Christ, and from the Ἀπομνημονεύματα τῶν ἀποστόλων (§ 36, 7) he derives his information about the historical life, teaching, and works of Jesus. The Gospel of John, although never mentioned, was not unknown to him, but it appeared to him more as a doctrinal and hortatory treatise than as a historical document, and undoubtedly his Logos doctrine is connected with that of John. He shows himself familiar with the Epistles of Paul, although he never expressly quotes from them. § 30.10. b. =Tatian=, a Greek born in Assyria (according to Zahn, a Semite) while engaged as a rhetorician at Rome, was won to Christianity by Justin Martyr, according to Harnack about A.D. 150. As the fruit of youthful zeal, he published an Apologetical Λόγος πρὸς Ἕλληνας, in which he treats the Greek paganism and its culture with withering scorn for even its noblest manifestations, and shared with his teacher the hatred and persecution of the philosopher Crescens. His later written Εὐαγγέλιον διὰ τεσσάρων (§ 36, 7) was a Gospel harmony, in which the removal of all reference to the descent of Jesus from the seed of David, according to the flesh, objected to by Theodoret, was occasioned perhaps more by antipathy to Ebionism than by any sympathy with Gnosticism. Zahn affirms, while Harnack decidedly denies, that this work was originally composed in Syriac. The exclusive use by the Syrians of the Greek name _Diatessaron_ seems to afford a strong argument for a Greek original. Its general agreement with the readings of the so-called Itala (§ 36, 8) witnesses to the West as the place of its composition. The introduction of a Syriac translation of it into church use in the East is to be explained by a longer residence of the author in his eastern home; and its neglect on the part of many of the Greek and Latin Church Fathers, and even their complete ignorance of it, may be accounted for by the fact that, while in the far East it was unsuspected, elsewhere it came to be branded as heretical (§ 27, 10).[69]
