I see no need for you to bring it up...
If they do bring up the argument, like... "time to go to church" and you just say "I'd rather not, you see... I don't believe in those things anymore"... that could be cool... or it could bring up a shitstorm, since you say your mom could be easily offended...
Ultimately, it's your call.
