347. [340.] 1) We take up marriage and adultery in particular because a person who is in a state of marriage possesses a marriage of good and truth, and a person who is in a state of adultery is in a state of evil and falsity, and because adultery encompasses every sin against the Decalogue, for anyone who engages in it engages in every evil forbidden by the Decalogue, and vice versa. Consequently, because these things are involved in and contained, so to speak, in summary form in marriage and adultery, therefore we take these up in particular. 2) Adulterous affairs are more prevalent today in the Christian world than in any other religious sphere because Christians separate good from truth, or charity from faith, and when these are separated, it is then impossible for people to know from influx any better. Therefore they defend adulterous affairs and not marriages; and consequently they do not know what married love* is. (Cite how today's faith is separated, and how it thus falsifies the Word and corrupts a person's rational faculty, giving rise to the experience of delights in adulterous affairs, and not so much in marriages.) * Or, conjugial love.
