Decades ago, I was a member of a local CoC. One Sunday, just a few seats from us, a visitor raised his hands in worship. No noise, just raising his hands.... not even waving them or anything like that. Someone nearer to him leaned over and informed him. "We don't do that here."
As far as I know, the man never darkened our door again. I think he recognized a Spiritual graveyard when he saw one.
