My foreign fiancee and I have different Religious Beliefs, will that present problems?

From a U.S. Immigration standpoint, couples who do not share same religious beliefs do stand a possibility of being denied during a U.S. Embassy Interview? Though it is rare, Interviewers may ask the K1 Applicant if he or she shares the same religious beliefs as their U.S. fiance? Even though there are many Christian faiths, the best answer to give is yes we both are Christians and leave it at that.
