>> I don't think it's "all" about money, but certainly that is a big part of it.
OK, so maybe that's a little harsh but consider the size of the bureaucracy here. The USCCB has an annual budget of over $130M and duplicates many of the functions of a large diocese. Bishops often live in splendor (how else to describe it).
The Ecclesiastic process is shrouded in secrecy.
Summary: an exclussive club atmosphere, lot's of money, and an unaccountable process leads to abuses. No suprises here.
