“Love is a decision, it is a judgment, it is a promise. If love were only a feeling, there would be no basis for the promise to love each other forever. A feeling comes and it may go. How can I judge that it will stay forever, when my act does not involve judgment and decision.”

“The importance of falling in love lies not in how it feels, but in what it perceives. And as always with our feelings, the key moral issue is how truthful the perception is... Falling in love is a sign that this might be someone with whom you could make a good marriage. Still, it's not enough, because the feeling is not always as perceptive as it should be... So falling in love is not the basis for a good marriage. It's not even a requirement. Marriage does not depend on falling in love; it depends on the promises you make to each other in your wedding vows and then spend a lifetime keeping. As many people have pointed out, you can't promise how you'll feel. But you can promise to cultivate a virtue, such as the virtue of love.”

“The immature conscience is not its own master. It simply parrots the decisions of others. It does not make judgments of its own; it merely conforms to the judgments of others. That is not real freedom, and it makes true love impossible, for if we are to love truly and freely, we must be able to give something that is truly our own to another. If our heart does not belong to us, asks Merton, how can we give it to another?”

“Genuine love is volitional rather than emotional. The person who truely loves does so because of a decision to love. This person has made a commitment to be loving whether or not the loving feeling is present. ...Conversely, it is not only possible but necessary for a loving person to avoid acting on feelings of love.”

“I promise to love you forever - every single day of forever.”

“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.”
