Whosoever puts away his wife, and marries another, commits adultery: and whosoever marries her that is put away from her husband commits adultery.
All Commentaries on Luke 16:18 Go To Luke 16
Augustine of Hippo
AD 430
Who are we to say that someone commits adultery in taking another woman after he puts away his wife, and that another who, in doing this, does not commit adultery? The Gospel says that everyone who performs such an act commits adultery. If everyone who marries another woman after the dismissal of his wife commits adultery, this includes the one who puts away his wife without the cause of immorality and the one who puts away his wife for this reason.
