Natoma said:As far as christian churches go, it is mandatory to pay 10% of your pre-tax income in Tithes. That's a pretty hefty chunk of change, particularly when you consider that there are millions of christians in this country who tithe.
I'm sure if you looked at Christianity as a corporation, it'd be, by far, the richest company in the world many times over.
I've noticed this tithing requirement isn't consistently implemented across denominations and between churches. At least that's how it looked from the ones I've run across.
As for denominations being corporations, it really depends. I think the Catholic church does pretty well, especially with its self-funded convention centers and golf courses. (Actually, I think these might generate income in some cases.)
If one considers the primary Mormon denomination christian, then LDS is wildly wealthy. They encourage a bit more than 10%, I think.
