CS Lewis - Sexual Morality

I'm aware CS Lewis' theology is often called into question. And I'm not saying I agree with every word the man's ever said, but I do want to share the following excerpts from a text of his. A friend posted these, and I think these words are very important in today's world.

Chastity is the most unpopular of the Christian virtues. There is no getting away from it: the Christian rule is, ‘Either marriage, with complete faithfulness to your partner or else total abstinence.’ Now this is so difficult and so contrary to our instincts, that obviously either Christianity is wrong or our sexual instinct, as it now is, has gone wrong. One or the other. Of course, being a Christian, I think it is the instinct which has gone wrong.

You can get a large audience together for a striptease act – that is, to watch a girl undress on the stage. Now suppose you come to a country where you could fill a theatre by simply bringing a covered plate on to the stage and then slowly lifting the cover so as to let every one see, just before the lights went out, that it contained a mutton chop or a bit of bacon, would you not think that in that country something had gone wrong with the appetite for food? And would not anyone who had grown up in a different world think there was something equally queer about the state of the sex instinct among us?

[Y]ou and I, for the last twenty years, have been fed all day long on good solid lies about sex. We have been told, till one is sick of hearing it, that sexual desire is in the same state as any of our other natural desires and that if only we abandon the silly old Victorian idea of hushing it up, everything in the garden will be lovely. It is not true. The moment you look at the facts, and away from the propaganda, you see that it is not.

They tell you sex has become a mess because it was hushed up. But for the last twenty years it has not been. It has been chattered about all day long. Yet it is still in a mess. If hushing up had been the cause of the trouble, ventilation would have set it right. But it has not. I think it is the other way round. I think the human race originally hushed it up because it had become such a mess. Modern people are always saying, ‘Sex is nothing to be ashamed of.’ They may mean two things. They may mean `There is nothing to be ashamed of in the fact that the human race reproduces itself in a certain way, nor in the fact that it gives pleasure.’ If they mean that, they are right. Christianity says the same. It is not the thing, nor the pleasure, that is the trouble. The old Christian teachers said that if man had never fallen, sexual pleasure, instead of being less than it is now, would actually have been greater. I know some muddle-headed Christians have talked as if Christianity thought that sex, or the body, or pleasure, were bad in themselves. But they were wrong. Christianity is almost the only one of the great religions which thoroughly approves of the body - which believes that matter is good, that God Himself once took on a human body, that some kind of body is going to be given to us even in Heaven and is going to be an essential part of our happiness, our beauty, and our energy. Christianity has glorified marriage more than any other religion: and nearly all the greatest love poetry in the world has been produced by Christians. If anyone says that sex, in itself, is bad, Christianity contradicts him at once. But, of course, when people say, ‘Sex is nothing to be ashamed of,’ they may mean ‘the state into which the sexual instinct has now got is nothing to be ashamed of’.

If they mean that, I think they are wrong. I think it is everything to be ashamed of. There is nothing to be ashamed of in enjoying your food: there would be everything to be ashamed of if half the world made food the main interest of their lives and spent their time looking at pictures of food and dribbling and smacking their lips. I do not say you and I are individually responsible for the present situation. Our ancestors have handed over to us organisms which are warped in this respect: and we grow up surrounded by propaganda in favour of unchastity. There are people who want to keep our sex instinct inflamed in order to make money out of us. Because, of course, a man with an obsession is a man who has very little sales-resistance. God knows our situation; He will not judge us as if we had no difficulties to overcome. What matters is the sincerity and perseverance of our will to overcome them.
