I know of only one actual flesh & blood case, in my years of connection to my congregation, where a lady broke up her marriage because of some variant of the MDR idiocy. Fortunately, her kids were grown & out of the house by then.
The funny thing is, I'm not sure I recall her going back & marrying the previous, OK-by-the-elders husband. I think she ended up marrying some other guy altogether, and moving about 4,000 miles away.
In the only other case where I know the people, a divorce had already taken place. There were tentative relationships starting up between various members, the new-Christian ex-husband, and the ex-wife who visited our gatherings frequently (because ex-hubby brought their children).
As I recall, without much of an attempt to build connections, pray & study together, or anything like that, the divided couple were told they could never marry anyone else, and they'd go to Hell if they did... and the wife was told she was, anyway, (a) because she had remarried and (b) because she wasn't a Christian (in that order). That really
made the ex-wife interested in the Lord and the Bible and His church, yes sir, yup!
Both of these situations (one when I wasn't a Christian yet, the other when we were attending elsewhere) show us that it will surely happen again, sometime, somehow, and that we will have to be ostracized for standing up for the people involved.
No way we'll be quiet if people are told to bust up families for a religious principle that's not black-and-white plainly spelled out. I don't even mean \"for an incorrect religious principle\". I mean that, if it were
correct, it would be by virtue of being built up out of a pile of cut & pasted Scriptures, all crocheted together, and requiring a scaffold of logical thought and inferences to be understood.
You don't go around hanging people's salvation on a hook of them
coming to the same conclusions you
found after stacking up a lacy Babel-tower of Scriptures. Even if you are right
, they don't see it for themselves, but they're going along with you, and are basing their salvation on the fruits of your mind
. That's not good enough, and won't last longer than your hold over the poor convert anyway.
