445. (i) Fornication is a product of sexual love.
We say that fornication is a product of sexual love because it is not sexual love, but arises from it. Sexual love is like a spring from which both conjugial love and scortatory love can be drawn; and they can be drawn by fornication, or without it. For everyone has sexual love in him, and it either emerges or it does not. If it emerges before marriage in relations with a woman of loose morals, it is called fornication; but if it does not emerge until he has a wife, it is called marriage. If it occurs with another woman after marriage, it is called adultery. Therefore, as stated, sexual love is like a spring from which a rivulet of chaste as well as unchaste love can flow. But it will be revealed in the following pages how much caution and how much prudence is needed for chaste love to develop through fornication, and how much imprudence for unchaste or scortatory love to develop through it. Can anyone draw this conclusion, that a person who has fornicated cannot be more chaste when he is married?
