Inter-religion relationships are only difficult if the both of you are active within your religious affiliations. My father raised me in strict muslim household. Staying out of hell was your main goal in life. Anyone that is raised in this type of environment is usually torn when it comes to accepting the faiths of others. Allah is the only God I have ever known. I remember calling my father and asking him about going to a non-denominational church and he told it was okay because I know who God is. The thing about religion is that we all tend to have the same religious beliefs as our fathers. As I got older I stopped practicing an organized religion but the majority of the teachings have stayed with me. I married a Catholic but it was never an issue because he was non-practicing. I didn't want to have my son christened because I didn't see the importance of it. It's almost as if I thought I would be putting a curse on him in some way. This is what organized religion does to your thinking. As I have gotten older I have come to believe that religion can sometimes be a monkey on our backs...a way of controlling our minds. I would suggest that you explore her beliefs and she explore yours. Most of the fundamental beliefs are the same in all organized religions. There is such a thing as right and wrong. Raise your child to be a God fearing person. Having strong ties to one religion does not guarantee a "purity" of the soul. I have had so many people try to shove their beliefs down my throat that it's ridiculous. Just do you and let your woman do her because if you two are decent God fearing people your child will hopefully grow up to be the same way and in the end that is all that matters, not the "label" that you give the child.
