This is because truly conjugial love is the height of chastity, as will appear below [143]; and the love opposed to it, which is called scortatory, is the height of unchastity. In so far therefore that it is purified of scortatory love, that love is chaste, for so far is its opposite, which destroys it, removed. From this it is plain that the purity of conjugial love is what is called chastity. Unchaste conjugial love can still exist without being real unchastity, as between a married couple who for various outward reasons so far refrain from expressing their wantonness as not even to think of it. Yet if that love is not purified in their spirits, it is still not chastity; it may have the form of chastity, but it lacks its essence.
