Savage wasn't being absurd, he was just being stupid.
How does the Roman Catholic Church qualify as "the richest religion in the world"? Cash flow? There isn't a lot of that - the Vatican runs a deficit more often than a surplus. Artwork? They do have a boatload of that, but how do you liquidate it? How do you sell the Sistine Ceiling or the Bernini Altar or the Raphael Room frescoes? Property? Short of turning St. Peter's into condos then how do you generate money from that? Yes, the Vatican is the guardian of some of the most valuable art treasures in the world. But for the purposes of liquidating into cash they're pretty worthless.
I am unable to come up with the exact article that I read where all of the properties owned around the world, not to mention artworks and other tangible ownings came up with the total that the Catholic Church is wealthier than any other church or denomination!
There is such an article out there but I can't point to it right now and I'm not merely claiming that it exists - it does and is very credible as the Catholic Church validated it.
Maybe some other FRers can help me research this information.
