It does not indeed follow that documents or chapters not quoted or utilized by the Fathers were in their day non-existent. The letters of Paul, supposing them to be genuine, would in any case be only gradually made common property. All the evidence goes to show that the early Christians were for the most part drawn from the illiterate classes; and the age of abundant manuscripts would begin only with the age of educated converts. But what is inconceivable is that one so placed as Paul should never once cite the teachings of the founder, if such teachings were current in his day in any shape; and what is extremely improbable is that one so placed as Clement, or one forging or interpolating in his name, should possess Paul's First Epistle to the Corinthians as it now stands, and yet should barely mention it in a letter to the same church dealing with almost the same problems. In the first case, we are almost forced to conclude that the gospel narratives were non-existent for the writer or writers of the Pauline epistles up to the point of the two interpolations which allege an accepted tradition; and, in the second, that the Pauline epistles themselves are nowhere to be taken as certainly genuine. [4] Such irremovable doubt is the Nemesis of the early Christian habits of forgery and fiction. There emerges, however, the residual fact that Paul ranked in the second century as a historical and natural personage, in whose name it was worth while to forge. For Paul's period, again, Jesus was possibly a historical personage, since he was not declared to be supernaturally born, though credited with a supernatural resurrection. Broadly speaking, the age of an early Christian document is found to be in the ratio of its narrative bareness, its lack of biographical myth, its want of relation to the existing gospels. As between the shorter and the longer form of the Ignatian epistles, the question of priority is at once settled by the frequent citations from the gospels and from Paul in the latter, and the lack of them in the former. But all the documents alike appear to point to a movement which remotely took its rise among the Jews long before the destruction of the temple of Jerusalem by Titus in the year 70, and subsisted in Jewry long afterwards; and, as the Jewish environment lacked many of the forces of change present in the Gentile, it is to the Jewish form of the cult that we must first look if we would trace its growth. § 2.
