That's a lot of taxes which are not payed.

Not that big of a deal, considering at one time The Vatican owned large chunks of the continent, it's still headquartered in Italy, most cardinals and such end up in Italy at some point. With a billion alleged members of the Church that breaks down to 1 property for every 200,000 members, it says that 14% of the property is rented at market rate and the rest at cut rate to Church employees, I'd view it very much in line with what other Churches like the United Methodist Church do, providing housing(Parsonage) for ministers. I mean the Church investment/real estate scandal is a big deal, but at the same time owning property across the planet when they have allegedly billions of people in their care, not out of the realm of probability, how many properties do other Governments own.... probably similar.
