Clement of Alexandria

Hence Paul speaks against people who are like those I have mentioned, saying: "You have then these promises, beloved; let us cleanse ourselves from all defilement of flesh and spirit, perfecting holiness in the fear of God." "For I am jealous for you with a divine jealousy, for I betrothed you to one husband to present a pure virgin to Christ." The Church cannot marry another, having obtained a bridegroom; but each of us individually has the right to marry the woman he wishes according to the law; I mean here first marriage. "I am afraid lest, as the serpent in his craftiness deceived Eve, so also your thoughts may be corrupted from the simplicity which is toward Christ," said the apostle as a very careful and conscientious teacher.
