Quoheleth,
it amazes me that churches don't bother to actually consider what kind of problem scenarios can occur and plan for them. While it's one thing to want to save someone's soul, it's entirely another to stand by and allow them to commit murder in the congregation.
Churches, like businesses, have to provide a safe place to work... and a lack of security at my office is no less a problem if I'm sitting in the pew listening to your sermon and happen to work at the church. It's surprising how many people have been killed in churches in recent years, and while the community outrage is always great, it's also "after the fact"... where a little planning would have the perp's friends and family grieving instead of the congregation.
I have an 8th degree in jujutsu, and have been training for almost 45 years, but whether or not I could wrest a firearm from a determined killer before the mayhem occurred is questionable, depending on both how skilled they were, and how much distance was between us. If I had my gun... the distance problem goes away, and there's no question that I would stop him. Unlike the shooting at Virginia Tech, where "duck and cover" was the only option, shooting back cures a lot of situations before they get out of hand. It's harder to shoot innocent people when you're dodging gunfire yourself.
The most innocuous firearm cover you can imagine is a Bible cover... and I have a friend who carries two Bibles to church... one with the word, and one with the 9x18 Makarov. It's a trick he learned in Russia. He has a hollowed out book with his firearm inside.
I don't suggest that you turn your church into an armed camp, but there's nothing wrong with having the flock protected. Our church has "foot patrols" that tour our parking lots because we've had people break into cars and church buildings while services were going on... and it's only one step up to having it turn into a violent encounter.
Unfortunately, in South Carolina, you have to have the church's permission to concealed carry in the building... but anyone who's actually up on what's going on in America these days should lean toward having some armed help in the congregation rather than trying to duck and cover. Our church family is elderly, and many of them would probably never move out of the way.
It's a ticklish situation, whether the pastor is packin' or the "flock"... but somebody better be these days.
