vatican II is the counter church and new religion.
It should all be condemned.
And that's basically what Archbishop Vigano says in this letter. He says it should be blotted out completely, the whole thing, and its whole "spirit", and that we should revert to Tradition ... not just have a few propositions condemned or revised.
This is the same argument Bishop Williamson has long made against +Fellay, that +Fellay is wrong that only 5% of the Council is bad, that the entire thing is polluted. Archbishop Vigano here agrees with this. Leaving that abomination on the books as an official Church Council would be a blight on the Catholic Church from which the Church's holiness, indefectibility, and Magisterial reliability could never recover. How could any Catholic really take the Magisterium seriously ever again?
