LS, that is a very interesting question indeed.

Even if your child never leaves your religion they can still take paths that are, well, bizarre. I was thinking something similar the other day, I know a Christian woman whose husband fell into the hands of a Christian cult. They started off appearing helpful and nice but soon started telling them how to live their life and turned him into a controlling, verbally abusive man. The advice she got from all her Christian friends? Leave him, now! Unfortunately she didn't as her beliefs are very anti divorce or separation. How would I handle that if this were my daughter? I would become the interfering MIL everybody hates. I couldn't just sit back and watch even if she claimed that supporting her husband in this made her happy. I would be in there with books, tracts and Bible verses to convince her that the Christianity this group preaches is not the same as that of the Bible. I would be offering real, physical assistance (he took away her car). And, of course, praying A LOT.
