Individuals should be endowed with this virtue according to their state in life: for some it will mean virginity or celibacy consecrated to God, which is an eminent way of giving oneself more easily to God alone with an undivided heart.[²⁷] For others it will take the form determined by the moral law, according to whether they are married or single. But whatever the state of life, chastity is not simply an external state; it must make a person's heart pure in accordance with Christ's words: "You have learned how it was said: You must not commit adultery. But I say this to you: if a man looks at a woman lustfully, he has already committed adultery with her in his heart."[²⁸]
