We should hardly be surprised that Satan would choose to give his best efforts at undermining the doctrine of the incarnation, for it is foundational to man’s redemption. Dr. Hick, one of the authors of The Myth of God Incarnate, is quick to draw the conclusion that once the incarnation is set aside, Christianity has no special or exclusive claim to redemption:
The problem which has come to the surface in the encounter of Christianity with the other world religions is this: If Jesus was literally God incarnate, and if it is by his death alone that men can be saved, and by their response to him alone that they can appropriate that salvation, then the only doorway to eternal life is the Christian faith. It would follow from this that the large majority of the human race so far have not been saved. But is it credible that the loving God and Father of all men has decreed that only those born within one particular thread of human history shall be saved? (p. 180).
