Are you SURE she had no Biblical grounds for divorce? Do you have absolute knowledge of what went on in that house? Or are you ASSuming she had no Biblical grounds for divorce? Lots of nasty stuff happens behind closed doors, and just because a person goes to church a lot and says all the right words doesn't mean they're a real Christian. Maybe he's an abuser, maybe he's a philander, maybe he's just an all around scumbag... or maybe she's the problem. Some divorces are a good thing, because some people should have been left at the altar but their spouse doesn't find out until too late. Make sure you get the facts before you pass judgement, because if it turns out there was a Biblical reason going on behind closed doors one of the two of them is going to need support from every friend they've got.
Can you find the verses where Christ allowed divorce for any reason EXCEPT for adultery?
Can you find any place that allows one to marry another while the divorced spouse is still alive?
Can you name someone who contemplated divorce in the NT but then didn't? What was divorce really considered by that person (what was his marital status when he thought of divorcing?)?
Yes I do. PERIOD
