It probably depends on the pack, but in ours there is a mix of religions (and non religious) and there is no problem at all. In the handbook there is some religious wording but it is mainly couched as "your religion" not specifically Christian. We are Jewish and do not attend temple, but our sponsor is a church. I also wanted to add that at I agree in that I feel strongly in the need to respect all religions (and the choice to be non-religious) and I would have a very hard time in a heavily dogmatic situation.
