On the theological side, the question is probably more far‐reaching than is commonly supposed. Individual Christian doctrines can never be treated _in vacuo_; they are inter‐related one with another. It is often said that those who reject the Virgin Birth reject also the physical Resurrection of Jesus, the Ascension, and many of the miracles reported in the Gospels. The statement is largely true; it is possible we ought also to include in it the doctrine of the Pre‐existence of Christ. The reason is that these denials belong to the same general habit of mind; they are part of the content of what has been called a “reduced Christianity”. It is impossible, therefore, adequately to discuss the question of the Virgin Birth on its theological side, without raising the larger question, whether this so‐called “reduced Christianity” is not the true faith, as distinguished from a “full Christianity” which in reality is florid and overgrown. Sweet can scarcely be said to go too far when he writes: “In short, and this is the gist of the whole matter, in this controversy concerning the birth of Christ, two fundamentally different Christologies are groping for supremacy” (ib., p. 311). This fact has not always been recognized by those who think of the Virgin Birth, but there can be no question of its truth. The Virgin Birth is part of a larger problem; it must ultimately be established, if at all, as a corollary, not as an independent conclusion. The larger problem is whether we can still hold the Trinitarian Theology and the Two‐Nature Doctrine of the Person of Christ, or whether we must give to the Immanence of God a place greatly in excess of any it has yet held in Christian thought; whether, indeed, we can feel it adequate to speak of Christ as One in whom the Immanent God revealed and expressed Himself in an altogether unique and ultimately inexplicable way. In any case, the conflict is one of Christologies. The purely naturalistic interpretation of Jesus holds a more and more precarious place in the field. This, then, is the problem of the present and of the immediate future. It is nothing less than the problem which every age has had to face since the days of Jesus of Nazareth—the problem of the Incarnation.
