Chastity is a virtue. A very important virtue. To be chaste is to have self-mastery, to be in control of your passions and sexuality. Contrary to what many people think, a person who exercises chastity is not repressing or rejecting the beauty of human sexuality. On the contrary, chastity preserves the human heart and body for authentic self-giving. All people, no matter their vocation in life, are called to chastity. Chastity is the virtue that prevents us from being slaves to our passions and acting like irrational animals.
