You worship here, I worship there

Here's a line you hear everyday in the club: What church do you go to and how often?

Well, maybe not.

The other day, I was watching an episode of My Wife and Kids where the oldest daughter dates a Bible-thumping teenager. She, of course, is a beautiful, hormonally-charged female. He is always in conflict between his lust and his religious upbringing, often acting as if a kiss is the most sinful thing.

While these two are portraying teenagers, they are also bringing up an issue that can affect adult relationships. Religion can have a great impact on your relationship. When the person attends church services on a nightly basis and serves on several deacon boards and you haven't stepped inside a church since you were christened, it may prove problematic. Or if you have answered a calling to become a minister and your significant other is an atheist, that could also go awry.

However, I have also seen couples of different religions and denominations have happy, fulfilling relationships through a lot of understanding. I've even witnessed people have children and opt to expose the children to both sides.
Do you believe the type or degree of religion automatically affects a relationship? Is someone being of the same religion a factor when you select a mate?
