The "great wealth" of which you speak, has been accumulated over centuries, and much of it is illiquid. Selling St. Peter's Basillica to Walmart--so they can have a Vatican City presence--would hurt more Catholics than it would help.
Why do you not also look at the charitible institutions provided by the Church? The hospitals, the orphanages, the ministries in foreign, inhospitable lands? India, Africa, South and Central America?
The Catholic church does good things as do most Christian denominations. But I know of no other Church (not cult) that has accUmulated anywhere near the assets of the Catholics. Again, I don’t care how much they own - I am just pointing out the contradiction of fighting for “social justice” while sitting on the largest fortune in the world. Not all could be liquidated but some of it certainly could.
