This passage from C.S. Lewis’s Miracles is one of my favorites on the miracle of the incarnation. I love the clarity and adoration. Merry Christmas.
“When St Joseph discovered that his fiancée was going to have a baby, he not unnaturally decided to repudiate her. Why? Because he knew just as well as any modern gynecologist that in the ordinary course of nature women do not have babies unless they have lain with men. No doubt the modern gynecologist knows several things about birth and begetting which St Joseph did not know. But those things do not concern the main point-that a virgin birth is contrary to the course of nature. And St Joseph obviously knew that. In any sense in which it is true to say now, “The thing is scientifically impossible,” he would have said the same: the thing always was, and was always known to be, impossible unless the regular processes of nature were, in this particular case, being overruled or supplemented by something from beyond nature.
When St Joseph finally accepted the view that his fiancée’s pregnancy was due not to unchastity but to a miracle, he accepted the miracle as something contrary to the known order of nature. All records of miracles teach the same thing. In such stories the miracles excite fear and wonder (that is what the very word miracle implies) among the spectators, and are taken as evidence of supernatural power. If they were not known to be contrary to the laws of nature how could they suggest the presence of the supernatural? How could they be surprising unless they were seen to be exceptions to the rules? And how can anything be seen to be an exception till the rules are known? If there ever were men who did not know the laws of nature at all, they would have no idea of a miracle and feel no particular interest in one if it were performed before them.
Nothing can seem extraordinary until you have discovered what is ordinary. Belief in miracles, far from depending on an ignorance of the laws of nature, is only possible insofar as those laws are known. We have already seen that if you begin by ruling out the supernatural you will perceive no miracles. We must now add that you will equally perceive no miracles until you believe that nature works according to regular laws. If you have not yet noticed that the sun always rises in the East you will see nothing miraculous about his rising one morning in the West.”
