347. [340] Marriage and adultery must be treated of especially, because he who is in marriage is in the conjunction of good and truth but he who is in adultery is in evil and falsity. And because adultery is all sin against the Decalogue, for he who is in that is in all the evil of the Decalogue and vice versa; and because these are involved and as it were contained in marriage and adultery in summaries, therefore they must be treated of especially. (2) At this day in the Christian world adulteries are more prevalent than in any other religion, because they separate good from truth or charity from faith; and when these are separated, then from influx it cannot be otherwise. Therefore they confirm adulteries and not marriages; and therefore it is not known what conjugial love is, it must be shown how the faith of the present day separates and thus falsifies the Word, then how it perverts man's rational, thence adulteries are delightful, but not so marriages.
