Mere Christianity - C. S. Lewis [61]
In other words, Theology is practical: especially now. In the old days, when there was less education and discussion, perhaps it was possible to get on with a very few simple ideas about God. But it is not so now. Everyone reads, everyone hears things discussed. Consequently, if you do not listen to Theology, that will not mean that you have no ideas about God. It will mean that you have a lot of wrong ones—bad, muddled, out-of-date ideas. For a great many of the ideas about God which are trotted out as novelties today are simply the ones which real Theologians tried centuries ago and rejected. To believe in the popular religion of modern England is retrogression—like believing the earth is flat.
For when you get down to it, is not the popular idea of Christianity simply this: that Jesus Christ was a great moral teacher and that if only we took His advice we might be able to establish a better social order and avoid another war? Now, mind you, that is quite true. But it tells you much less than the whole truth about Christianity and it has no practical importance at all.
It is quite true that if we took Christ’s advice we should soon be living in a happier world. You need not even go as far as Christ. If we did all that Plato or Aristotle or Confucius told us, we should get on a great deal better than we do. And so what? We never have followed the advice of the great teachers. Why are we likely to begin now? Why are we more likely to follow Christ than any of the others? Because He is the best moral teacher? But that makes it even less likely that we shall follow Him. If we cannot take the elementary lessons, is it likely we are going to take the most advanced one? If Christianity only means one more bit of good advice, then Christianity is of no importance. There has been no lack of good advice for the last four thousand years. A bit more makes no difference.
But as soon as you look at any real Christian writings, you find that they are talking about something quite different from this popular religion. They say that Christ is the Son of God (whatever that means). They say that those who give Him their confidence can also become Sons of God (whatever that means). They say that His death saved us from our sins (whatever that means).
There is no good complaining that these statements are difficult. Christianity claims to be telling us about another world, about something behind the world we can touch and hear and see. You may think the claim false, but if it were true, what it tells us would be bound to be difficult—at least as difficult as modern Physics, and for the same reason.
Now the point in Christianity which gives us the greatest shock is the statement that by attaching ourselves to Christ, we can ‘become Sons of God’. One asks ‘Aren’t we Sons of God already? Surely the fatherhood of God is one of the main Christian ideas?’ Well, in a certain sense, no doubt we are sons of God already. I mean, God has brought us into existence and loves us and looks after us, and in that way is like a father. But when the Bible talks of our ‘becoming’ Sons of God, obviously it must mean something different. And that brings us up against the very centre of Theology.
One of the creeds says that Christ is the Son of God ‘begotten, not created’; and it adds ‘begotten by his Father before all worlds’. Will you please get it quite clear that this has nothing to do with the fact that when Christ was born on earth as a man, that man was the son of a virgin? We are not now thinking about the Virgin Birth. We are thinking about something that happened before Nature was created at all, before time began. ‘Before all worlds’ Christ is begotten, not created. What does it mean?
We don’t use the words begetting or begotten much in modern English, but everyone still knows what they mean. To beget is to
