Augustine: “You must not have wives whose former husbands are living; nor may you, women, have husbands whose former wives are living. Such marriages are adulterous, not by the law of the courts, but by the law of Heaven. Nor may a woman who by divorce has withdrawn from her husband become your wife while her husband lives. Only because of fornication may one dismiss an adulterous wife; but in her lifetime you may not marry another. Neither to you, O women, is it granted to find husbands in those men whose wives have quitted them by divorce: such are adulteries, not marriages.”
Origen:
[1] But now, contrary to what was written, even some of the rulers of the church have permitted a woman to marry—even when her husband was living doing contrary to what was written. For it is said, ‘A wife is bound so long as her husband lives.'”

[2] “A woman is an adulteress—even though she seems to be married to a man—if the former husband is still living Likewise also, the man who seems to marry the woman who has been put away, does not so much marry her as commit adultery with her—according to our Saviour.”
