You have to understand that Trid refuses to admit that doctrine can change. I gave him the obvious example of Pope Pius IX saying that the idea that "every man can worship as he pleases" is "an insanity"; while the Vatican II document Dignitatis Humanae says that freedom of religion is a right of all humanity. Trid claims that because DH does not say it is an absolute right, then the two statements do not contradict each other. This shows the absurd lengths Trid will go to defend his idea that doctrine cannot change.
