At work I suspect a number of use are to put it bluntly atheists. I guess it’s because we’re more highly educated. And some of us did either part of all of our education in Catholic schools.
In my case it was the first twelve years. In a co-worker’s case it was the entirety right through college. He says he doesn’t go to church, I say I gave up organized religion for Lent one year and never looked back. It injects a certain humor into it.
