So far, I think I'm the only poster from the ONLY state not to have CC... I carry anyway, because, luckily I'm a sworn officer. I always carry (period). That includes church and other places (correctional settings and federal facilities are the only prohibited places for me).
I've never been asked and never told anyone at church. Among our congregation are a couple correctional officers, a couple retired city police officers, myself, and a Dpty Sheriff, who happens to have killed a man who was begining to cut the throat of an infant he was holding when the dpty shot him. We all know one-another, and the pastor and a lot of the church family know what we do. I don't know if they wonder if we're carrying, but I know they'd look to us to take care of a bad situation developed...
A couple years ago, a mentally-disturbed man came to church. I knew him quite well from past dealings -knew him by name. I made a mental note that I'd never seen him here before and kept an eye on him. The Dpty wasn't there that service, so I was pretty much on my own. Right at the beginning of the sermon he stood up and asked the pastor if he could speak. It was quite an uncompfortable situation, but the pastor said, "sure." I got up quietly and moved around behind the guy, but the pastor looked at me and shook his head negatively, which I took to mean 'don't do anything, but keep standing ready.'. The guy said his piece and sat down, and we went on with services. We never spoke of the incident again, but I think the pastor appreciated prepared help that also let him continue to be in charge of the service.
The info about the United Methodists really shocked me, and I looked up my church's position and found they don't have one. A survey of the pastors of the church shows they're pretty neutral to leaning pro-gun, and very conservative (including pro-death penalty at a 70% rate!). About 70% were pro-gun and 15% neutral. Not bad. The survey was run on some other denominations, and it looks like the most anti-gun was the Mennonites. Interestingly, they also had the widest spectrum (pretty evenly spread actually) of political beliefs too, which implied to me they are the least politically-activist within the church...
