It should not be thought that because such indications are indirect they are therefore any the less certain. There is perhaps hardly a single uncanonical Christian document that is admittedly and indubitably older than Marcion; so that direct evidence there is naturally none. But neither is there any direct evidence for the antiquity of man or of the earth. The geologist judges by the fossils which he finds embedded in the strata as relics of an extinct age; so here, in the Gospel of Marcion, do we find relics which to the initiated eye carry with them their own story.
Nor, on the other hand, can it rightly be argued that because the history of these remains is not wholly to be recovered, therefore no inference from them is possible. In the earlier stages of a science like palaeontology it might have been argued in just the same way that the difficulties and confusion in the classification invalidated the science along with its one main inference altogether. Yet we can see that such an argument would have been mistaken. There will probably be some points in every science which will never be cleared up to the end of time. The affirmation of the antiquity of Marcion's Gospel rests upon the simple axiom that every event must have a cause, and that in order to produce complicated phenomena the interaction of complicated causes is necessary. Such an assumption involves time, and I think it is a safe proposition to assert that, in order to bring the text of Marcion's Gospel into the state in which we find it, there must have been a long previous history, and the manuscripts through which it was conveyed must have parted far from the parent stem.
The only way in which the inference drawn from the text of Marcion's Gospel can be really met would be by showing that the text of the Latin and Syriac translations is older and more original than that which is universally adopted by text-critics. I should hardly suppose that the author of 'Supernatural Religion' will be prepared to maintain this. If he does, the subject can then be argued. In the meantime, these two arguments, the literary and the textual—for the others are but subsidiary—must, I think, be held to prove the high antiquity of our present Gospel.
CHAPTER IX.
TATIAN—DIONYSIUS OF CORINTH.
Tatian was a teacher of rhetoric, an Assyrian by birth, who was converted to Christianity by Justin Martyr, but after his death fell into heresy, leaning towards the Valentinian Gnosticism, and combining with this an extreme asceticism.
The death of Justin is clearly the pivot on which his date will hinge. If we are to accept the conclusions of Mr. Hort this will have occurred in the year 148 A.D.; according to Volkmar it would fall not before 155 A.D., and in the ordinary view as late as 163- 165 A.D. [Endnote 238:1] The beginning of Tatian's literary activity will follow accordingly.
Tatian's first work of importance, an 'Address to Greeks,' which is still extant, was written soon after the death of Justin. It contains no references to the Synoptic Gospels upon which stress can be laid.
An allusion to Matth. vi. 19 in the Stromateis of Clement [Endnote 238:2] has been attributed to Tatian, but I hardly know for what reason. It is introduced simply by [Greek: tis (biazetai tis legon)], but there were other Encratites besides Tatian, and the very fact that he has been mentioned by name twice before in the chapter makes it the less likely that he should be introduced so vaguely.
The chief interest however in regard to Tatian centres in his so- called 'Diatessaron,' which is usually supposed to have been a harmony of the four Gospels.
