“Don't use words too big for the subject. Don't say infinitely when you mean very; otherwise you'll have no word left when you want to talk about something really infinite.”

“I am trying here to prevent anyone saying the really foolish thing that people often say about Him: I’m ready to accept Jesus as a great moral teacher, but I don’t accept his claim to be God. That is the one thing we must not say. A man who was merely a man and said the sort of things Jesus said would not be a great moral teacher. He would either be a lunatic — on the level with the man who says he is a poached egg — or else he would be the Devil of Hell. You must make your choice. Either this man was, and is, the Son of God, or else a madman or something worse. You can shut him up for a fool, you can spit at him and kill him as a demon or you can fall at his feet and call him Lord and God, but let us not come with any patronizing nonsense about his being a great human teacher. He has not left that open to us. He did not intend to.”

“Next to the Blessed Sacrament itself, your neighbor is the holiest object presented to your senses.”

“I thought I saw how stories of this kind could steal past a certain inhibition which had paralysed much of my own religion in childhood. Why did one find it so hard to feel as one was told one ought to feel about God or the sufferings of Christ? I thought the chief reason was that one was told one ought to. An obligation to feel can freeze feelings. And reverence itself did harm. The whole subject was associated with lowered voices; almost as if it were something medical. But supposing that by casting all these things into an imaginary world, stripping them of their stained-glass and Sunday School associations, one could make them for the first time appear in their real potency? Could one not thus steal past those watchful dragons? I thought one could.”

“The future is something which everyone reaches at the rate of sixty minutes an hour, whatever he does, whoever he is.”

“A young man who wishes to remain a sound atheist cannot be too careful of his reading.”

“Strictly speaking, there are no such things as good and bad impulses. Think...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.”

“The typical expression of opening Friendship would be something like, 'What? You too? I thought I was the only one!”

“Do not waste time bothering whether you ‘love’ your neighbor; act as if you did. As soon as we do this we find one of the great secrets. When you are behaving as if you loved someone, you will presently come to love him.”

“The sane would do no good if they made themselves mad to help madmen.”

“A moderated religion is as good for us as no religion at all—and more amusing.” 

“And as Jill gazed at its motionless bulk, she realized that she might as well have asked the whole mountain to move aside for her convenience.”

“The false religion of lust is baser than the false religion of mother-love or patriotism or art: but lust is less likely to be made into a religion.”

“Bent creatures are full of fears”

“Being in love is a good thing, but it is not the best thing. There are many things below it, but there are also things above it. You cannot make it the basis of a whole life. It is a noble feeling, but it is still a feeling. Now no feeling can be relied on to last in its full intensity, or even to last at all. Knowledge can last, principles can last, habits can last but feelings come and go. And in fact, whatever people say, the state called ‘being in love’ usually does not last. If the old fairy-tale ending ‘They lived happily ever after’ is taken to mean ‘They felt for the next fifty years exactly as they felt the day before they were married,’ then it says what probably never was nor ever would be true, and would be highly undesirable if it were. Who could bear to live in that excitement for even five years? What would become of your work, your appetite, your sleep, your friendships? But, of course, ceasing to be ‘in love’ need not mean ceasing to love. Love in this second sense — love as distinct from ‘being in love’ — is not merely a feeling. It is a deep unity, maintained by the will and deliberately strengthened by habit; reinforced by (in Christian marriages) the grace which both partners ask, and receive, from God. They can have this love for each other even at those moments when they do not like each other; as you love yourself even when you do not like yourself. They can retain this love even when each would easily, if they allowed themselves, be ‘in love’ with someone else. ‘Being in love’ first moved them to promise fidelity: this quieter love enables them to keep the promise. it is on this love that the engine of marriage is run: being in love was the explosion that started it.”
