I've already pointed out to you that Pope St. Pius X was aware of the rot back in 1907.
The rot is modernism and its spawn was VCII and the Novus Ordo. And I hope you know what "novus" means.
And the rot was a few decades older than him ... and neither he nor his successors moved effectively against it. They allowed it to fester, until it exploded in the 1960s.
We must learn from this period in our history, not just pretend it was all sweetness and light.
