On the Feast of Saint Augustine, his words on the wedding at Cana:
Even setting aside any mystical interpretation, the fact that the Lord was pleased to be asked, and to go to a marriage, showeth plainly enough that He is the Author and Blesser of marriage. There were yet to be those of whom the Apostle hath warned us as forbidding to marry; who say that marriage is a bad thing in itself, and a work of the devil. Yet we read in the Gospel that when the Lord was asked, Is it lawful for a man to put away his wife for every cause? He answered that it was not lawful, except it were for fornication. In which answer ye will remember that He used these words: What God hath joined together, let not man put asunder.They who are well instructed in the Catholic religion know that God is the Author and Blesser of marriage; and that, whereas joining together in marriage is of God, divorce is of the devil.
