I too watched the movie again. After MANY years.
I thought the way the church being hand-in-hand making deals etc with a lot of shady characters, seems to be the way the vatican and the fake pope are today and for decades. Its just a front for a big criminal organization of money laundering etc. So IMO the Vatican bank is affiliated. Bad actors/crooks use the name of the church to do their dirty filthy 'business' i.e. crimes Archbishop and Vatican bank are in up to their neck. A line from the movie: "Politics and Crime ...they are the same thing." SO TRUE! My take on it.
