And where does that 8% go to after that?
Where does the Vatican get its funds? Banking?
And no, I’m not being snarky; I’m genuinely curious in this case.
Much comes from direct donations, some is from tourism, some is from the annual Peter’s Pence collection.
Keep in mind the Vatican is self-supporting. It is a country... yet also global. It’s not the executive function of a huge corporation or charity, as many people suppose. It is not a pyramid but a circle.
The 8% from the parishes goes to the Diocese and is used therein by bishop for chancery and programs. It does not “go” anywhere else.
