The present work is, in part, a foot‐note to, or illustration of, this principle. We may therefore be pardoned for a further reference to it in a passage from F. C. Burkitt’s _Gospel History and its Transmission_, in which it finds an almost classic statement: “Our belief or disbelief in most of the Articles in the Apostles’ Creed does not ultimately rest on historical criticism of the Gospels, but upon the general view of the universe, of the order of things, which our training and environment, or our inner experience, has led us severally to take. The Birth of our Lord from a virgin and His Resurrection from the dead—to name the most obvious Articles of the Creed—are not matters which historical criticism can establish” (p. 350 f.). It is clear, then, that if further advance is to be made, we must enter the realms of doctrine. What doctrinal purpose, we must ask, does the Virgin Birth serve? Does it explain the sinlessness of Jesus? Is it necessary to the doctrine of the Incarnation? Is it congruous with the doctrine of the Person of Christ? It is not contended that an answer to these questions in the affirmative would prove the event to have happened. Nevertheless, such an answer would unquestionably invest the New Testament tradition with a yet higher probability, sufficiently great, in our judgement, to make belief in its historical character reasonable. If, however, we have to answer the doctrinal questions in the negative, then the historical character of the tradition receives a fatal blow. The opinion, so frequently expressed, that, in any case, the Virgin Birth is not a doctrine of essential importance, is one that calls for scrutiny. If it means that a man may be a sincere follower of our Lord, whether he believes the doctrine or not, it is, of course, a truism. But if it means that the doctrine is of no importance in relation to the Incarnation and the Person of Christ, that is perhaps the strongest argument that can be adduced _against_ the credibility of the miracle. What is doctrinally irrelevant is not likely to be historically true. It does not fall in with the scope of this work to enter fully into the theological question. Our purpose has been to examine the historical and critical questions and to show where the real problem lies. Criticism cannot solve that problem. Nevertheless, its contribution is not barren. It can discuss interpolation theories; it can treat of the literary form which the tradition has assumed in the Gospels. It can date—imperfectly it is true—the time when the belief became current. It can apply broad tests of credibility. We ourselves believe that it can say the miracle may have transpired. But it cannot say more. The last word is with Theology.
