It would be laughable if it weren't so pernicious.
I never thought I'd see the day when I had to argue against "Trads" who assert that the Papal Magisterium and the Church's Public worship could become corrupt and harmful to souls. It's really unbelievable to me.
We are not asserting that the papal magisterium can err, heck, you posted the authentic teachings of the Church stating the opposite - unlike you, we are the ones who actually believe it. As such, you have no grounds whatsoever to make such utterly absurd accusations.
The Church's public worship is not corrupt, never has been corrupt and can never be harmful to souls. Apparently you like making absurd accusations by the bucket full.
If you ever realize that the NO is not the Church and that it's public worship truly is a corruption of the Catholic worship, which does indeed make the NO public worship harmful to souls, then you will have accomplished something.
