So this is an interesting topic. There's training classes I frequent south of Atlanta. The lead instructor is also the head of security of some mega church. They've approved CCW in their churches (I think there are two large campuses), if the CCW holders take his class (with a discount of course).
I'm a deacon at our church in a more rural area. The current law is just a misdemeanor with a $100 fine, if charges are filed by the church. Several of us carry concealed on Sunday and when the deacon board pursued granting CCW permission, they found out it was more of an insurance hassle than taking no stance.
Our church won't press charges if there's legal use of a firearm for one's self-defense or stopping another from committing gun violence on our church property. All other legal protections are the responsibility of the shooter. This is a win-win in my assessment. They're not giving anybody permission to carry, but they won't press charges or have any issues if you are legally carrying on their church property. This probably helps to dissuade open-carry...not that I'm against it, but CCW is more respectable to those not comfortable around firearms in their local church.
