“The promise, made when I am in love and because I am in love, to be true to the beloved as long as I live, commits me to being true even if I cease to be in love. A promise must be about things that I can do, about actions: no one can promise to go on feeling in a certain way. He might as well promise to never have a headache or always to feel hungry.”

“Knowledge can last, principles can last, habits can last; but feelings come and go... 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 marriage) the grace which both partners ask, and receive, from God... "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.”

“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.”

“If people do not believe in permanent marriage, it is perhaps better that they should live together unmarried than that they should make vows they do not mean to keep. It is true that by living together without marriage they will be guilty (in Christian eyes) of fornication. But one fault is not mended by adding another; unchastity is not improved by adding perjury. The idea that 'being in love' is the only reason for remaining married really leaves no room for marriage as a contract or promise at all. If love is the whole thing, then the promise can add nothing; and if it adds nothing, then it should not be made.”

“You are told to love your neighbour as yourself. How do you love yourself? When I look into my own mind, I find that I do not love myself by thinking myself a dear old chap or having affectionate feelings. I do not think that I love myself because I am particularly good, but just because I am myself and quite apart from my character. I might detest something which I have done. Nevertheless, I do not cease to love myself. In other words, that definite distinction that Christians make between hating sin and loving the sinner is one that you have been making in your own case since you were born. You dislike what you have done, but you don't cease to love yourself. You may even think that you ought to be hanged. You may even think that you ought to go to the Police and own up and be hanged. Love is not affectionate feeling, but a steady wish for the loved person's ultimate good as far as it can be obtained.”

“I remember Christian teachers telling me long ago that I must hate a bad man's actions but not hate the bad man: or, as they would say, hate the sin but not the sinner. ...I used to think this a silly, straw-splitting distinction: how could you hate what a man did and not hate the man? But years later it occurred to me that there was one man to whom I had been doing this all my life -- namely myself. However much I might dislike my own cowardice or conceit or greed, I went on loving myself. There had never been the slightest difficulty about it. In fact the very reason why I hated the things was that I loved the man. Just because I loved myself, I was sorry to find that I was the sort of man who did those things.”

“Always' was a promise! How can you just break the promise?" "Sometimes people don't always understand the promises they're making when they make them," I said.Isaac shot me a look. "Right, of course. But you keep the promise anyway. That's what love is. Love is keeping the promise anyway. Don't you believe in true love?"I didn't answer. I didn't have an answer.But I thought that if true love did exist, that was a pretty good definition of it.”
