Not wishing to possibly upset anyone, I have only alluded to what I see as the actual teaching concerning a second marriage and adultery, but here it is from the Douay-Rheims translation from the Vulgate:
“But I say to you, that whosoever shall put away his wife, excepting for the cause of fornication, maketh her to commit adultery: and he that shall marry her that is put away committh adultery.” --Matthew 5:32
“And I say to you, that whosoever shall put away his wife, except it be for fornication, and shall marry another, committeth adultery; and he that shall marry her committeth adultery.” Matthew 19:9
“And he saith to them: Whosoever shall put away his wife and marry another, committeth adultery against her. And if the wife shall put away her husband, and be married to another, she committeth adultery.” Mark 10:11-12
“Every one who putteth away his wife and marrieth another, committeth adultery: and he that marrieth her that is put away from her husband, committeth adultery.” Luke 16:18
The sole reference to the one “put away” committing adultery is found in Matthew 5:32, and here the husband who puts her away “maketh her to commit adultery”. Look carefully at the wording in both Matthew 19:9 and Luke 16:18 in particular. What might this really mean?
