I know what the Christian community is going to say ( I already know the difference between philos, eros, and agape), so save it. The fact that two people love each other without any regard to their beliefs (or lack of them) is possible, but are they able they live together? If they procreate would there be conflicts in the raising of the offspring? and for love's sake, could the couple stay together? Would God allow it? (He is agape after all).
