even if a multitude of parishioners leave the church is won't affect it one bit - I'm not so sure about that...Take Boston, for example - after SPOTLIGHT was broadcast (I saw the movie btw, and it was excellent!), many CC properties in MA had to be sold off for lack of $$$ support. And the younger generation does not feel the need to join organized religions.
I read recently the Pope will soon visit Ireland - the CC is losing it's grip on Ireland, witnessed by Ireland's recent vote to end the ban on abortions... IRELAND VOTES TO END ABORTION BAN, IN REBUKE TO CATHOLIC CONSERVATISM https://www.nytimes.com/2018/05/26/world/europe/ireland-abortion-yes.html
