Yet, again, admitting these writers as witnesses, and allowing that they quote from the same Gospels, their quotations only prove that the isolated phrases they use were in the Gospels of their day, and are also in the present ones; and many such cases might occur in spite of great variations in the remainder of the respective Gospels, and would by no means prove that the Gospels they used were identical with ours. If Josephus, for instance, had ever quoted some sentences of Socrates recorded by Plato, that quotation, supposing that Josephus were reliable, would prove that Plato and Socrates both lived before Josephus, and that Plato wrote down some of the sayings of Socrates; but it would not prove that a version of Plato in our hands to-day was identical with that used by Josephus. The scattered and isolated passages woven in by the Fathers in their works would fail to prove the identity of the Gospels of the second century with those of the nineteenth, even were they as like parallel passages in the canonical Gospels as they are unlike them.
It is "important," says the able anonymous writer of "Supernatural Religion," "that we should constantly bear in mind that a great number of Gospels existed in the early Church which are no longer extant, and of most of which even the names are lost. We will not here do more than refer, in corroboration of this fact, to the preliminary statement of the author of the third Gospel: 'Forasmuch as many ([Greek: polloi]) have taken in hand to set forth a declaration of those things which are surely believed among us, etc.' It is, therefore, evident that before our third synoptic was written, many similar works were already in circulation. Looking at the close similarity of the large portions of the three synoptics, it is almost certain that many of the [Greek: polloi] here mentioned bore a close analogy to each other, and to our Gospels; and this is known to have been the case, for instance, amongst the various forms of the 'Gospel according to the Hebrews,' distinct mention of which we meet with long before we hear anything of our Gospels. When, therefore, in early writings, we meet with quotations closely resembling, or, we may add, even identical with passages which are found in our Gospels--the source of which, however, is not mentioned, nor is any author's name indicated--the similarity, or even identity, cannot by any means be admitted as evidence that the quotation is necessarily from our Gospels, and not from some other similar work now no longer extant; and more especially not when, in the same writings, there are other quotations from apocryphal sources different from our Gospels. Whether regarded as historical records or as writings embodying the mere tradition of the early Christians, our Gospels cannot for a moment be recognised as the exclusive depositaries of the genuine sayings and doings of Jesus; and so far from the common possession by many works in early times of such words of Jesus, in closely similar form, being either strange or improbable, the really remarkable phenomena is that such material variation in the report of the more important historical teaching should exist amongst them. But whilst similarity to our Gospels in passages quoted by early writers from unnamed sources cannot prove the use of our Gospels, variation from them would suggest or prove a different origin; and, at least, it is obvious that quotations which do not agree with our Gospels cannot, in any case, indicate their existence" ("Sup. Rel.," vol. i., pp. 217-219).
