Currently, my husband and I are mostly on the same page as far as religion goes.... but I have dated people in the past of differing religions.

I don't believe that if you're going to have a romantic relationship it's necessary that the two people involved are the same religion, but on the same token I also believe that being on the same page religion-wise tends to make things easier..... and if you are going to persue some sort of lifelong commitment to someone of another faith, absolutely discuss the impact with your partner that it will have.... Especially in regard to what you're going to do about raising children.
