Mere Christianity

by C.S. Lewis

The reader should be warned that I offer no help to anyone who is hesitating between two Christian ‘denominations’. You will not learn from me whether you ought to become an Anglican, a Methodist, a Presbyterian, or a Roman Catholic. This omission is intentional (even in the list I have just given the order is alphabetical). There is no mystery about my own position. I am a very ordinary layman of the Church of England, not especially ‘high’, nor especially ‘low’, nor especially anything else.

In the first place, the questions which divide Christians from one another often involve points of high Theology or even of ecclesiastical history, which ought never to be treated except by real experts. I should have been out of my depth in such waters: more in need of help myself than able to help others. And secondly, I think we must admit that the discussion of these disputed points has no tendency at all to bring an outsider into the Christian fold. So long as we write and talk about them we are much more likely to deter him from entering any Christian communion than to draw him into our own.

When two Christians of different denominations start arguing, it is usually not long before one asks whether such-and-such a point ‘really matters’ and the other replies: ‘Matter? Why, it’s absolutely essential.’

These, then, are the two points I wanted to make. First, that human beings, all over the earth, have this curious idea that they ought to behave in a certain way, and cannot really get rid of it. Secondly, that they do not in fact behave in that way. They know the Law of Nature; they break it. These two facts are the foundation of all clear thinking about ourselves and the universe we live in.

Strictly speaking, there are no such things as good and bad impulses. Think once again of a piano. It has not got two kinds of notes on it, the ‘right’ notes and the ‘wrong’ ones. Every single note is right at one time and wrong at another. The Moral Law is not any one instinct or set of instincts: it is something which makes a kind of tune (the tune we call goodness or right conduct) by directing the instincts.

What is the good of telling the ships how to steer so as to avoid collisions if, in fact, they are such crazy old tubs that they cannot be steered at all? What is the good of drawing up, on paper, rules for social behaviour, if we know that, in fact, our greed, cowardice, ill temper, and self-conceit are going to prevent us from keeping them?

And it would seem, at first sight, very sensible to stop before we got there, and just carry on with those parts of morality that all sensible people agree about. But can we? Remember that religion involves a series of statements about facts, which must be either true or false. If they are true, one set of conclusions will follow about the right sailing of the human fleet: if they are false, quite a different set.

Human beings judge one another by their external actions. God judges them by their moral choices.

People often think of Christian morality as a kind of bargain in which God says, ‘If you keep a lot of rules I’ll reward you, and if you don’t I’ll do the other thing.’ I do not think that is the best way of looking at it. I would much rather say that every time you make a choice you are turning the central part of you, the part of you that chooses, into something a little different from what it was before. And taking your life as a whole, with all your innumerable choices, all your life long you are slowly turning this central thing either into a heavenly creature or into a hellish creature: either into a creature that is in harmony with God, and with other creatures, and with itself, or else into one that is in a state of war and hatred with God, and with its fellow-creatures, and with itself. To be the one kind of creature is heaven: that is, it is joy and peace and knowledge and power. To be the other means madness, horror, idiocy, rage, impotence, and eternal loneliness. Each of us at each moment is progressing to the one state or the other.

I really like this

Each has done something to himself which, unless he repents, will make it harder for him to keep out of the rage next time he is tempted,

Is this what repentance is for?

When a man is getting worse he understands his own badness less and less. A moderately bad man knows he is not very good: a thoroughly bad man thinks he is all right. This is common sense, really. You understand sleep when you are awake, not while you are sleeping. You can see mistakes in arithmetic when your mind is working properly: while you are making them you cannot see them. You can understand the nature of drunkenness when you are sober, not when you are drunk. Good people know about both good and evil: bad people do not know about either.
