Given the context, it sounds like you could get away with first correcting the person, “Would you please refrain from insulting my faith? It makes me feel uncomfortable and is very in appropriate to say in the workplace.”For those of you inquiring, it is in the US and the person is a different christian denomination.
Unless this person is psychologically unstable or prone to bullying and intimidation, this alone should put a stop to it. When the more charitable option is possible - in this case, talking directly to the co-worker before going over his/her head - it’s best to start there.
