Awgee, forgive my ignorance, but what other kind of churches are there besides Christian ones? If you're Muslim you call it a mosque, and if you're Jewish you go to temple or synagogue. Did you mean to use the word "church" as a generic term, like "Kleenex" for "tissues"? If so, I'm no expert, but I'm thinkin' that might be something lots of people would indeed find offensive.
