"Let me now say in conclusion that this commandment demands also that every one love and esteem the spouse given him by God. For where conjugal chastity is to be maintained, man and wife must by all means live together in love and harmony, that one may cherish the other from the heart and with entire fidelity. For that is one of the principal points which enkindle love and desire of chastity, so that, where this is found, chastity will follow as a matter of course without any command. Therefore also St. Paul so diligently exhorts husband and wife to love and honor one another."
