I looked it up.
One of them is sodomy.
Hmmmmmmm ....
The problem here is unbelieving Catholics (including some priests and bishops) who wanted to keep getting the perks without believing the Faith.
The Church has always taught steadfastly against sodomy, and moreover has always ruled (from the Middle Ages to the present, including a ruling in the 1960s) that homosexual tendencies (not even amounting to conduct) should bar a candidate from seminary. 1. It's a "near occasion of sin" - putting a homosexually inclined individual in close quarters with other men is a constant temptation; 2. A homosexual - unlike a normal man - is not giving up anything for the sake of Christ and His Church. He's more like Willie Sutton in a bank.
You had some priests and a few bishops in the Swinging Sixties and Seventies who decided on their own to jettison much of the Church's teaching - particularly that homosexual conduct wasn't a grave sin. That opened the door to the infestation of predatory homosexuals. A few notorious seminaries became "pink palaces" - I know personally several men who would have been great priests who quit because they couldn't stand the corruption and even persecution.
At this point, it appears that the Church has done a fairly good job of cleaning house. They may have swung too far in the opposite direction (accusation equals conviction) but that may be inevitable for awhile.
Yep. As I understand it, that list was put together from the Biblical situations where sins became go grievous that God put a stop to them through cataclysmic action. Like the oppression in Egypt that brought on the plagues and the sin of Sodom that brought on the fire and brimstone.
