Seriously Nick, Paulcc1 brings up an EXCELLENT point. Aside from worshiping the Lord, church is BIG, BIG business. In fact, it's so big it's terrifying. Even around here, in rural Alberta, these guys are all packing Martins, and the congregation will do whatever Pastor Dude says. Personally, I've never hit that market as I have a thing about using God for personal gain or benefit, but obviously there's a whole stack of people who have no such reservations.
Now, being a shyster aside. When we have dealt with religion and sold them stuff they actually did need, the cheque NEVER bounces...then again, in God we Trust, everyone else pays cash, card, or debit.
