"What is your faith, if you don't mind my asking?"
Yes I do mind. I have found it advisable to not disclose my personal religion here as it usually leads to many character assaults and is not productive nor germane to the conversation.
I am also not one who needs to wear my religion on my sleeve.
But if you are embarrassed or afraid I guess that's up to you.
However, if you want to subtly knock what others believe and how they want to go about running their church, it might be more forthright to admit what your religion is...if you have one.
So you do admit to wearing sleeves, then?
