Keep the Faith

Interfaith relationships are very interesting to me. Probably because its an example of why you don't need to take your particular denomination too seriously. One glaring example of this is Jewish/Christian couples.  So the foundation of Christianity is the belief that Christ was God on Earth and you can only achieve salvation by accepting him as your savior. Isn't that in rather stark contrast to the belief he was a heretic and a phony? Christmas sort of highlights this.  I suppose it's a bit of an Abrahamic Romeo and Juliette sort of situation.
