Oklahoma is working on adding churches to the "Castle Domain" which simply means one would have the "Right" to Defend oneself, family and friends while attending church. Currently I am not aware of any ban on CC in Oklahoma churches. The only ban in Oklahoma is Government property and educational property or any establishment that properly posts a "No Weapons" sign on their front door. We have one restaurant that has a sign inside that says you cannot bring a gun into their place of business because they serve beer/alcohol. Since food is their primary business and there is no legal posting on the entrance door, this sign is basically worthless.. Of course if properly concealed..nuff said. I carry at church. Statistically one is more likely to be injured by violence in church than by fire and every public place is required to have working and inspected fire extinguishers. Go figure. Also look up "Gatekeepers" in Ezekiel.
