Yeah... we know that’s not infallible now, and neither are outright bans.
It’s like the adage about what the most dangerous part of a car is. It’s the nut behind the wheel.
I am a spiritual nut myself, and would certainly caution against sweeping moves based on infrequent incidents. What does this need to do to the overall social balance around laws pertaining to firearms? It might need to do nothing. Churches might stand to get more guards, however. The bouncer is a valid church ministry. Even those, however, being prepared with a mixture of measures, to be able to exercise deadly force (as a secular citizen under the 2nd Amendment) and yet as a Christian seek to forego it if something else to subdue an attack is yet possible. Since Christian faith may call for martyrdom in the attempt to save an enemy, any approach that rules this possibility out will be less than Christian.
As a deacon in the church it is my scriptural calling to provide for the physical needs of the church. I view physical security as one of those needs. It is a matter of stewardship of what God has entrusted to us, whether it be family, the church, or society in general.
