Can I, someone born into a Jewish family but adopted and raised catholic, take my partner to church to clear up some misconceptions he has?

Hi there,

I converted from Catholicism to Judaism at the start of college. My partner, a Buddhist, was raised in the deep south and was raised that church was singing and dancing and all of that. I, on the other hand, went through the ritual of sit stand sit stand kneel, and it confuses him. Would it be appropriate to take him to observe a mass? Thanks
