Yet another class of interpolations may possibly be found in certain passages in the Gospels which later conditions obtaining within the Christian Church have shaped. That later experience did interpret the words of Jesus and give the sense of them in its own terms, need not be questioned. But it should always be remembered that in any suspected case, the process may well have been complete by the time that the Evangelists wrote, and that the passage is not an interpolation at all. There are very good grounds for this opinion even in cases in which variations in rendering can be cited from patristic and other sources, as, for example, in the case of the Great Commission in Mt. xxviii. 19. This fact makes it all the more difficult to concede an interpolation where the textual record is unbroken, though again the possibility that such cases do exist may well be left open. The cases just considered help us when we come to think of _doctrinal modifications_. As regards these, it is important to draw again a distinction which has been already made. We must distinguish, on the one hand, between those instances of doctrinal modification that are due to the Evangelists themselves, and which are in no sense interpolations, and, on the other hand, those which may subsequently have been made by later scribes or readers. Cases of the former kind unquestionably occur in the Gospels. We have only to examine the way in which the First and Third Evangelists have treated the Second Gospel, which lay before them, to be assured of this. Alterations, e.g., are made out of a sense of reverence for the person of Jesus (cf. Allen, ICC., St. Mt., p. xxxi f.). Mt. xix. 17 (“Why askest thou me concerning that which is good?”), and the changes which Mk. vi. 5 f. has been subjected to, both in Mt. and Lk., will serve as illustrations.
