The State of GA doesn’t allow weapons on church property...
But, why does The State have any say in the matter at all? (Nevermind any constitutional (including from the state’s constitution) RKBA that such a measure would abrogate.)
The State of Florida does not list churches as a “prohibited zone” for CC.
We go to a large church, with multiple services, and there is a “security” detail at each service. These are people in the congregation who volunteer for it and have their CCP. Also many of the staff have CCPs, and I’m sure some of them carry.
