(2) _To what point, then, can we trace this tradition?_ We have argued that the Virgin Birth tradition first began to gain currency in the circles in which St. Luke moved at the time when the Third Gospel was being written. We have also seen that the tradition was already known to the readers of the First Gospel. If these conclusions are valid, it is evident that the relative order in which the two Gospels were written will determine the farthest point to which we can trace the Virgin Birth tradition as publicly known. What, then, is the order of composition in the case of Mt. and Lk.? We may frankly admit that if priority must be assigned to Mt., it becomes difficult to understand how St. Luke could have no knowledge of the Virgin Birth at the time when he first took up his pen. For, on this view, we ask, Must not the tradition have already reached the circles in which he was moving at the time? It would certainly be more favourable to our theory if we could assign priority to the Third Gospel. In this case we should have a very simple account to give of the history of the tradition. We should discover it emerging for the first time in St. Luke’s Gospel, and we should have a ready explanation (in the fact of the interval between the two works) for the apologetic note in the later Gospel. But the priority of the two Gospels is not a question to be decided simply by the attitude which the Evangelists display towards the Virgin Birth. Mt. and Lk. must be compared throughout. When this is done there do not appear to be sufficient grounds for giving a vote in either direction (cf. Stanton, GHD., ii, p. 368). All that we can say is that the two Gospels are independent works, and must have been written about the same time. If there was an interval, it cannot have been great, for there are no sufficient signs that either writer was acquainted with the work of the other. It is especially difficult to think that St. Luke would have neglected the First Gospel, if it had been accessible to him (cf. Lk. i. 1‐4). If, however, we accept, as a working hypothesis, the view that the two Gospels were written independently of each other, and more or less simultaneously,(104) it will still follow that the Virgin Birth tradition was already known in at least one influential primitive Christian community (that to which the First Gospel was addressed) while it was unknown to St. Luke.(105) Is this a fatal objection, or does such a position represent what may well have been the actual situation? We do not think that the difficulty is too great. The tides by which traditions flow in different places are not simultaneous; they differ in time, in height, and in volume. No practice could be more mischievous than the habit of dating the relative spread of early beliefs simply by the dates of contemporary documents. Regard must be paid to local conditions.
