This is the way I deal with this issue:

My religious faith is very important to me. In fact, it is the most important thing I have, and the most important quality I possess. I would not enter into a relationship where I could not share this important part of my life with the other person. The one time I dated someone with beliefs significantly different than mine, it ended in heartbreak. I did fall in love with him, but knew it wouldn't go anywhere because I had no intent of marrying him. It wasn't fair to him or myself to continue dating him when I realized it was getting serious and I still had no intent of marrying him.

It does not make you mean to want to marry someone that shares your religous beliefs. It makes you smart. If he is talking about a relationship, I would end the "dating" phase of your friendship, and keep a friendship that will most certainly expand your horizons and your understanding of another culture.
