And I say unto you, Whosoever shall put away his wife, except it be for fornication, and shall marry another, commits adultery: and whoever marries her who is put away does commit adultery.
All Commentaries on Matthew 19:9 Go To Matthew 19
Augustine of Hippo
AD 430
De Conjug. Adult., ii, 9: For a reunion of the wedlock, even after actual commission of adultery, is neither shameful nor difficult, where there is an undoubted remission of sin through the keys of the kingdom of heaven; not that after being divorced from her husband an adulteress should be called back again, but that after her union with Christ she should no longer be called an adulteress.
