This is actually an old Native American Indian tradition practiced in the tribes of northern Michigan back in French missionary days.
Call me when they start using real guns and bullets. Til then, give it a rest.
BTW, more Europeans dies each year from summer heat than Americans die from guns.
During the Hajj, muslims go to a special site to literally throw stones at 3 pillars which represent Satan and the way he tempts us.
Wonder if the jack-a-hoos complaining about the imagery used, complain about ubiquitous violence on news, tv, movies, video games. If they did, they would die of exhaustion.
I think the Pastor might want to present biblical ways to resist the devil. Jesus quoted scripture. We are instructed to submit to God, and to resist the devil, Guns are symbolic but not very biblical. Maybe use whips, slings, spears, and swords! Trusting in God is better, but sadly, much harder to do. IMHO.
