Flame meant the butcher was pagan - NOT the spouse.
For what it's worth, a lot of stuff in the Bible (in my opinion), is superfluous stuff, and not 'benchmarks for salvation'. So long as the benchmarks are met and agreed upon within our relationship, then a differing opinion on the importance of tongues, or how God created the world, or whatever, is really 'by the by' for us.
When it comes to our children, we've agreed that in these areas of the Bible where there is disagreements between denominations (ie tongues, birth control, how God created the world, etc), we will just share purely from the Bible what is said, and explain it to them in a way that they are free to make up their own mind on what they believe. I'm willing to be taught if my belief is off, and I think, that if my FH and I raise our kids to ask questions, challenge traditional belief, and to study for themselves what the Bible says, it won't be that much of a drama.
The important thing, as SK said, is HOW you resolve the issue. My partner and I don't have identical beliefs (which is great in my opinion - allows a lot of conversations!), but we don't go around trying to 'educate' each other to change their minds. We ask for explanations, and so long as their explanation can be backed up biblically, then it's all good.
Some people can't do that though, and think if their partner doesn't have an identical belief pattern as them, there is no way for a relationship to grow and flourish. I tend to think that kind of relationship is unhealthy.
