It really comes down to a worldview issue. The Christian worldview is so drastically different from any other that it becomes incompatible. Just a few of the things that could cause major problems in a marriage:
- I believe that God is in charge of my life, and therefore, what he tells me to do, I will do. What if God asks me to do some specific thing with my life, and my spouse will not support it because he doesn't recognize God's leading? Then I have to disobey God in order to maintain relationship with my spouse. Not good.
- I believe that God wants me to raise my children to follow him. What if my spouse is against this? How can our children be raised in the way I think is right if one parent disagrees?
- I believe that all things in life must be dealt with through prayer and the Christian community. If my spouse is not a Christian, I lose the most vital prayer partner I could ever have. Who will support me if my faith wavers? Who will help me make the tough decisions when it comes to God's will for us and our family? I would end up turning to outside people for support and advice, instead of to my spouse. Again, not good.
- How will we cope with things like death and sickness? Our worldviews again preclude us from agreeing, or from fully being able to support each other emotionally and *spiritually*, which is vital for me.
- What about finances? I want to give money to my church and to Christian causes. What if my spouse doesn't?
- Most importantly, we would be missing the spiritual bond which is the sweetest thing God ever invented for human relationships. There is nothing better than being connected with someone emotionally, physically, intellectually, AND spiritually. This means that a non-Christian would make a second-rate spouse for me compared to a Christian, with whom I could share *everything*.
As for marrying a Christian from a different denomination, that is much less of a problem since one person can easily switch. The only hindrance there is that many of us are attached to our specific congregation--emotionally, spiritually, socially, etc--so a switch would be tough. But it would be worth it for the right guy.
