Greetings Mr. Sin,
I'd like to start with a reading from the 'good' book.
Deuteronomy 22:10 - Thou shalt not plow with an ox and an ass together.
Most of any religious holy book is hog wash. But even a blind dog gets lucky every once in a while, and a broken clock is right twice a day.
I'd recommend that you either find an agnostic, or one with not much religion to start with, and turn them into an atheist with honest discourse and debate. If you can't then I wouldn't bother with them. Think about how much trouble there would be 10-15 years down the road when they are dragging your children to crazy churches to save their soul.
It wouldn't be so bad if you married someone that doesn't believe in a hell. But the problem with most of them is that they are so darn self-righteous & holier-than-thou.
I recently married an Agnostic (I'm an Atheist, and yes there's a difference). Now, we're expecting a child. I can't imagine the fights we would be having if she was a faith-head.
Sincerely,
Green Magi
