152. (10) Chastity cannot be ascribed to people who do not believe that adultery is an evil against religion, and still less to those who do not believe that adultery is harmful to society. Chastity cannot be ascribed to people like this because they do not know what chastity is, nor even that it is possible. For chastity has to do with marriage, as we showed under the first heading here; and although religion in married partners makes marriage chaste, people who do not believe that adultery is an evil against religion also regard marriage as unchaste. Thus nothing to them is chaste. Consequently it is pointless to speak to them of chastity. People like this are deliberate adulterers. On the other hand, people who do not believe that adultery is harmful to society know even less than the first kind of people what chastity is or that it is possible. For they are purposeful adulterers. If they say that marriage is less unchaste than adultery, they say it with the lips but not with the heart, because marriages in their case are cold. And people who speak from this state of coldness about a state of chaste warmth cannot have any idea of the chaste warmth in conjugial love. What these people are like, and the ideas of their thought, and therefore the interior ideas in their speech, will be seen in Part Two on the insanities of adulterers.
