In all seriousness, to flesh that out:
"I think they've been told" (re: Jews) just means that in your religion, you have a tenet that Jews were supposed to believe in Jesus, but didn't, so "officially" -- in your mind -- Judaism includes everything you imagine Christianity to encompass.
However, Judaism always has included procedures for divorce,
for any reason. (Well, at least for the man... I said we've always had divorce, not that it's been egalitarian.) Marriage itself has grown in complexity from a time when you could throw a garment over a woman who's cold, and go from there, to the time when a written contract needed to be signed for a marriage, likely introduced well prior to Christianity.
I'd be interested to see the "laws" on divorce that actually appear in the greek bible, which Christians appended to the tanakh.
I do know that Paul grudgingly wrote that getting married, while not a good thing per se, is better than "to burn." (1 Corinthians 7:8-9)
Paul of Tarsus said:
8 I say therefore to the unmarried and widows, it is good for them if they abide even as I.
9 But if they cannot contain, let them marry: for it is better to marry than to burn.
This of course reflects the historically inaccurate prediction by Jesus that he would return within the lifetime of his followers -- after all, if you believed it would be a thousand or two thousand years until the
parousia, you'd immediately establish a project to continue normal life until such time as the
parousia -- and of course, the kingdom -- came to pass; if you believed it would happen in a radically accelerated time-frame, you would have the question of whether an unmarried person should marry.
Whatever later rationalizations a given sect of Christianity came up with thereafter may be satisfying to adherents of that sect, but they do not square with the beliefs of that religion's founders. Not my problem, believe what you want to believe. But there it is.
Now what's the scripture on divorce in Christianity?
Can you quote scripture that forbids divorce in Christianity? Because Paul also allows for divorce and remarriage in cases of unfaithfulness and in cases where the spouse is not a "believer."
This does not preclude other passages saying the opposite, of course. But I'm interested in seeing the prohibitions in black and white.
