From Marcion we now turn to Tatian, another so-called heretic leader. Tatian, an Assyrian by birth,(1) embraced Christianity and became a disciple of Justin Martyr(2) in Rome, sharing with him, as it seems, the persecution excited by Crescens the Cynic(3) to which Justin fell a victim. After the death of Justin, Tatian, who till then had continued thoroughly orthodox, left Rome, and joined the sect of the Encratites, of which, however, he was not the founder,(4) and became the leading exponent of their austere and ascetic doctrines.(5) The only one of his writings which is still extant is his "Oration to the Greeks"[------]. This work was written after the death of Justin, for in it he refers to that event,(6) and it is generally dated between {145} a. d. 170-175. (l) Teschendorf does not assert that there is any quotation in this address taken from the Synoptic Gospels;(2) and Canon Westcott only affirms that it contains a clear reference" to "a parable recorded by St. Matthew," and he excuses the slightness of this evidence by adding: "The absence of more explicit testimony to the books of the New Testament is to be accounted for by the style of his writing, and not by his unworthy estimate of their importance."(3) This remark is without foundation, as we know nothing whatever with regard to Tatian's estimate of any such books. The supposed "clear reference" is as follows: "For by means of a certain hidden treasure [------] he made himself lord of all that we possess, in digging for which though we were covered with dust, yet we give it the occasion of falling into our hands and abiding with us."(4) This is claimed as a reference to Matt. xiii. 44: "The kingdom of heaven is like unto treasure hidden [------] in the field, which a man found and hid, and for his joy he goeth and selleth all that he hath and buyeth that field." So faint a similarity could not prove anything, but it is evident that there are decided differences here. Were the probability fifty times greater than it is that Tatian had in his mind the parable, which is reported in our first Gospel, nothing could be more unwarrantable than the deduction that he must have derived it from our Matthew, and not from any other of the numerous Gospels which we know to have early been in circulation. Ewald ascribes the parable in Matthew originally to the "Spruchsammlung" or collection of Discourses, the second of the four works out of which he considers our first Synoptic to have been compiled.(1) As evidence even for the existence of our first canonical Gospel, no such anonymous allusion could have the slightest value.
