"The Virgin Birth cannot be understood in abstraction from the triumphant consummation of Christ’s life in his resurrection, for it is there that the mystery of his Person is revealed.
In fact the birth of Jesus of the Virgin Mary and the resurrection of Jesus from the virgin tomb (wherein no human being had ever been laid) are the twin signs which mark out the mystery of Christ, testifying to the continuity and the discontinuity between Jesus Christ and (fallen time and) our fallen humanity.
... The empty tomb points to the revelation of the secret of Christ and as such is the authentication of the Virgin Birth; it is the unveiling of what was veiled, the resurrection out of our mortality of what was inserted into (time) it and recreated within it. But such a resurrection: of true Man and true God points back to the Virgin Birth of Jesus as a union of true God and true Man... Thus the mystery of the Virgin Birth is the basis of the mystery of the resurrection. By the mystery of the resurrection the mystery of the Virgin Birth becomes effective and understandable. Here we have a closed circle; to deny the Virgin Birth involves a denial of the resurrection, and vice versa."
