The more exactly we understand the riches of virginity, the more we must bewail the other life; for we realize by this contrast with better things, how poor it is. I do not speak only of the future rewards in store for those who have lived thus excellently, but those rewards also which they have while alive here; for if any one would make up his mind to measure exactly the difference between the two courses, he would find it nearly as great as that between heaven and earth.

On Virginity, Chap. 3
