I would not like to think that there was not someone(s) in the congregation that were not legally able to carry in order to protect themselves and the rest of us from an insane person intending on committing a hate crime in the church.
A youth pastor friend of my in KY tells me that his Sr. Pastor encourages his people to carry in church. At coffee some time ago they talked about asking people as the came in if they were packing and if not then have some loaner guns to give them. Not an original idea but novel none the less. There are a lot of us Pistol Packing Preachers who do it legal.
