It might be possible for someone else to have a different interpretation of this passage…
Are you contending that Judaism and Christianity worship different beings?
I was going to ask about that overlyverbose until I decided that she had pretty explicitly stated that Christians bask in light whereas the rest of us cower in darkness and are by our very non-Christian nature covered in a haze of immorality. Although that analogy really isn’t all that controversial-when the pope went to India on Diwali once I remember the press reporting some statement he made along the lines of the fact that all the Hindus were keeping lights in the windows of their houses but had none in their heart. Stuff like that used to really, really anger me until I realised that every religious group has a certain segment of the population that truly believes everyone else is doomed.
Yay for religious tolerance! 
As someone who was raised Protestant, became “nothing”, converted to Judaism and married a Jewish man, I think there should be more relationships between people from different religious backgrounds (as long as the parties involved can work out a religious arrangement that works for them, whatever that might be). I think there’d be less religious hatred and intolerance in the world if more people were willing to take a chance on someone who isn’t from the same religious background as they are.
My relationship with my husband has not suffered even though he is religious and I am not. We’re adults. We can differ on our opinions, even debate them heatedly, without getting upset. (Hell, I wouldn’t want someone who agreed with me all the time-- I enjoy debating too much. 
) I respect his choices and he respects mine.
Any person who would refuse to have a relationship with you because you are not of their faith is not worth being with in the first place. That kind of “my way or the highway” attitude is a BIG red flag, in my opinion.
Well then it looks like you have three choices:
1)Lissa and I are both liars.
2)The verse is wrong.
3)The hand of God works in mysterious ways and His purpose in creating these two mixes has not yet been revealed.
Take your pick!
I think you shouldn’t go to her church… unless your willing to put up with it every sunday for years to come. Its one thing just trying to get to know what her life is like… its another to join it in a blase way.
Religion can be a problem in a relationship… my ex-GF never said it out loud… but it bothered her that I’m an atheist (she is a spiritist). She never tried to impose it upon me… but whenever I was curious and did give it some attention her hopes tended to fly high that I might become more religious. Naturally I didn’t.
So if it doesn’t bother you going to church … fine… but you shouldn’t be just tagging along. Either your in it for real or not. So for social sake just say that you have to be with your family on Sunday and only very ocassionaly go to church with her. Its her religion… not yours. She should understand that.
Also do make it clear that your “kids” will be raised in whatever she wants… that seems a major point with religious chicks.
Take care where you walk…
When I met my atheist husband I was clinging to the last vestiges of some sort of deism and was unsure I wanted to get involved with an atheist.
Now I’m an atheist, too.
I guess the moral of this story is: People change. And everyone has to make her own decisions about where these things fall in importance.
I’m glad I decided to hook up with my heathen boy.
I am in a mixed-religion marrage. My wife was born and raised LDS, strong practicing girl, father was a bishop and all that.
I was born and raised Roman Catholic, then went agnostic before becoming a Buddhist.
The key to a successful relationship of this nature is communication and acceptance. She needs to know your stance and if you are or are not keen on considering conversion to her faith. Before you get married (if you do one day down the line) first figure out what would happen with the kids and all.
My wife is 100% accepting of me and my choices and has had to defend me in front of people in her congregation a few times. More times than not it’s not an issue. Once her parents saw how well i treated her they got used to the idea and had no problems with it (however keep in mind parents can be the stickiest of these issues and make her life difficult if they decide not to be adult about the whole thing).
My dad and step-mom have a mixed-faith relationship. My dad is atheist, my step-mom Christian. She doesn’t go to church, and doesn’t believe in organized religion, only in Jesus and the Bible. My dad and I are strict believers in evolution, while my step-mom and step-brother are creationists. We all live peacefully in the same household. We don’t discuss religion often, but when we do, it is done with respect. I should mention that of all the women I’ve seen my dad date (and marry) throughout my lifetime, he’s truly happy for the first time with this one.
However, my step-brother has recently gotten the “gotta save people bug” and is convinced that one day, my dad and I will be saved. I have respect for anyone’s religion as long as they’re not shoving it down my throat. It now takes considerable self-control to have these discussions with him, so I avoid it whenever possible.
Watch out for that, as others have mentioned, otherwise… I don’t see the problem. Good luck!
In response to the OP:
I’d like to preface this by saying, in a nutshell, yes it’s possible (though, maybe given some provisos).
Somewhat like you, I was raised in a sort-of religious household. Over time, I’ve become fairly lapsed, and somewhat more skeptical. I’m not what many would call a religious person, but I still consider myself a theist. My girlfriend of 3 years (likely spouse in the next few years) is an apathetic agnostic - she’s not religious, but definitely not an atheist. We’ve had the requisite theological discussions several times, and I think we’ve grown a bit closer personally, as well as theologically. We’re still not of the exact same mindset, but considering we don’t really hold contradictory viewpoints, and that we’re both at least fairly apathetic and agnostic…I don’t think it will be a problem.
At least, I hope not.
I first started to post this several days ago, and since then I see several other people have posted anecdotes that support this as well. I guess in summation, I think it’s more difficult for the relationship to work the more the viewpoints differ between the partners…and also based on the degree of vehemence with which each person regards his or her position. But still I don’t think it’s impossible, it just isn’t easy.
