Pseudo-Chrysostom
Catena Aurea · Matthäusevangelium 19
And I say unto you, Whosoever shall put away his wife, except it be for fornication, and shall marry another, committeth adultery: and whoso marrieth her which is put away doth commit adultery.
For every thing by whatsoever causes it is created, by the same is it destroyed. It is not matrimony but the will that makes the union; and therefore it is not a separation of bodies but a separation of wills that dissolves it. He then who puts away his wife and does not take another is still her husband; for though their bodies be not united, their wills are united. But when he takes another, then he manifestly puts his wife away; wherefore the Lord says not, Whoso putteth away his wife, but, Whoso marrieth another, committeth adultery.
