Settlements have been handled by each diocese and their own insurance, etc. A quick word about Church organization. A diocese is operationally and financially independent of Rome. So, when a new school or seminary needs to be built, those monies must come from the diocese and its donors, not from Rome.
While the story of abuse by priests has been large, and the victims numerous, it has also involved cases that are sometimes 40+ years old, and outside of the statute of limitations, therefore, no settlements. In other words, there are more stories than settlements.
The Roman Catholic Church is not a monolith. It is composed of 23 autonomous churches (think Eastern), and 2795 diocese (Vatican, Annuario Pontificio 2009, p. 1172).
Finally, what would it matter if Pope requested, and received additional monies? Perhaps it would mean more food for the starving, medicine for the sick, care for the aged, education for the ignorant. Would you be opposed to such things?
I appreciate your even-tempered and fact-rich answer, and I’ll think on it.
Thanks and FRegards
