I used to think it was the Catholic church...perhaps whimsically based on perception.....just because they had the most elaborate cathedrals and were the oldest of religions. But I think they have lost quite a bit of money with legal settlements and have lost a lot of membership over the past few years.
I wonder what the various religions are doing to make money? Surely they don't depend on tithes...that's a mere pittance.
Big stock portfolios? real estate? Swiss banks? Any ideas?
What do the various churches do to increase their wealth now?
Which religion do you think has the most money?
