Though I speak with the tongues of men and of angels, and have not charity, I am become as sounding brass, or a tinkling cymbal. And though I have the gift of prophecy, and understand all mysteries, and all knowledge; and though I have all faith, so that I could remove mountains, and have not charity, I am nothing. And though I bestow all my goods to feed the poor, and though I give my body to be burned, and have not charity, it profiteth me nothing.
Charity never faileth: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away. For we know in part, and we prophesy in part. But when that which is perfect is come, then that which is in part shall be done away.
When I was a child, I spoke as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things. For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known.
And now abideth faith, hope, charity, these three; but the greatest of these is charity.
Note that the King James Version (1 Corinthians 13) uses both the words charity and love to translate the idea of caritas / ἀγάπη: sometimes it uses one, then sometimes the other, for the same concept. Most other English translations, both before and since, do not; instead throughout they use the same more direct English word love, so that the unity of the teaching should not be in doubt. Love can have other meanings in English, but as used in the New Testament it almost always refers to the virtue of caritas.
