Just went through this myself. Im a woman and a Christan..I dated an agnostic man for a little over a year and finally mutually decided to stop trying to make it work. I am pretty confident saying I will never again date anyone who is not a Christian. Sounds like she thinks like I do. My opinion is this : Don't waste her and your time. Move on.
Holy ****, move on. Also, forget sex. This might sound like me being facetious but I'm being serious if you're actually into this. Just like I wouldn't begrudge someone who's religious refusing to date me as an atheist, I also couldn't date someone who's religious. Just wouldn't be as fun, and it would always create underlying issues. Just move on.
From my prior knowledge, there is a better chance to keep a relationships going is if you both are the same religion. But that doesn't mean it can't work out.
I might use "devout" loosely. I don't recommend "faking" it. I did say lie, but that's not the best choice of words. I said what I said earlier because I am not the "thumping" type. If someone wants to be a Christ follower, they will. If they get hung up on the story of it, and it disallows them to follow, that's fine, too. Do I believe there used to be a talking snake? LOL. I'm not even gonna answer that question. I think people get too caught up in the literal translation of "the book" and overlook the principle of it all. Ie: the golden rule, forgiveness, and so on. I'm not preacher, and I'm still pretty young, so take whatever I say with a grain.
I'm starting to notice that some Christians today aren't quite the same as they were in older times and they "lose their way" more often than usual. I don't judge because I'm not perfect, but I'm finding more and more Christian gals that are pretty much willing to get to "know you" (biblically) before you put a ring on it. It's all on an individual basis.
I've learned at an early age that just because someone calls themselves religious (some are indeed "riligulous") and is in the church 3 times a week, it doesn't mean squat. I follow the majority of the Bible's principles. Do I fall short? Of course I do! Any Christian that says they haven't sinned is either lying, or just hasn't sinned, yet (better never even THINK of anal sex, lol). I'm a sinner. I repent daily for the sins I commit. Do I use the "repent" clause as a crutch? I honestly try not to. My sins aren't going out and coveting my neighbor's girl or killing anyone or even stealing from anyone. I practice anal sex with women whenever they ask for it, lol. TMI? That's not my only thing. I swear, I got drunk like 4 days ago, let's not even start on the premarital sex! Sorry for such a long post, but basically, my point is this: the "image" that God made us in (you know, "made us in his own image") is my endgoal. I'm a born sinner, and my goal is to be as righteous as possible.
My girlfriend, who just moved in with me, is a spiritual seeker of sorts. Raised as a Christian, she still identifies herself as a Christian, but is very interested in all religions as well as overall spirituality. She has been researching Buddhism as of late, and is interested in Judaism. I was raised Jewish, and still identify myself as Jewish, but I've become more secular as I've grown older. She and I have gone to Friday night services together and will do so again in a couple of weeks. I respect her spiritual search and do everything I can to assist and/or stay out of the way, and she respects my secularism (sprinkled with Rastafarian habits ). It's worked out well so far. I believe people of different religions can date/be in a relationship as long as neither party tries to force their beliefs, or lack of beliefs, on the other.
this is true for the most part. on a side note - Christians are people too. To expect them not to make mistakes or sin is expecting too much. They have the same feelings everyone else has..but we are expected to have restraint and not give in to our desires. Only through that discipline can we be more Christ-like. However, to expect a Christian to never sin is just flat unrealistic. That is why Jesus said "he who is without sin cast the first stone" and nobody threw a stone. I will say that it is definitely harder life living as a Christian than it is to live as a non-believer.
OP, you're questioning this from the get go... so... I'm willing to bet it won't work for you. Don't waste her time just to get in her pants and then breaking it off because of some dumb reason like yours. What about FUTURE knowledge?
Religious beliefs are as big or small a deal as the people in the relationship make it. If she already told you that she only dates people who share her beliefs then you have your answer. It's not really fair to you or her to fake believing, so unless there is something about this girl you like so much that you are willing to be "open minded" about religion and attend services with her to see what happens, it doesn't really matter what other people's experiences are. It's not likely she will change her mind, so being with her would depend on you fitting into her religious expectations. The stronger each person's opinion is on the subject, the more difficult it will be to make it work. Some one who is agnostic, who simply says they aren't religious, and doesn't bring up the topic unless they are asked, is going to be easier for a religious person to have a relationship with, than some one who loves to share their opinion on being agnostic and debate who is "right" or worse insult anyone who doesn't agree with their opinion. Likewise, it is easier to make a relationship work with some one of a different faith who doesn't discuss their faith on a regular basis, and much more polarizing with people who like to discuss it all the time, and who try to make unsolicited attempts to convert others to their beliefs. The more vocal either person's opinion is on their beliefs, the more they should consider finding someone who has the same beliefs.
