I will pray for you wisdom, both of you. There needs to be a comonality to Bible interpretation in the home that brings a closeness and unity. I am having kind of the same issues, not within my family, but within my church family, there are some styles of worshiop being presented that make me very uncomfortable, even though on some of the aspects they are very biblical, I feel convicted about them so it is hard to discern what is biblical and what is just "the way we have always done it", I will be in prayer for you both as I said, let the Bible speak, and where it doesn't we shouldn't either, I hope this helps, I know it is not much of an answer, but maybe at least you wont feel as if you are alone in this struggle.THank you, writing this response to your request has given mea lighter look at my own struggle.
Lord Bless,
Brad
