I have a hard time understanding what you are saying. For starters, Christ promised that the Holy Spirit would always be with the Church, protecting it from error. I learned that in the 1950’s from the Baltimore Catechism.
If we take one of the documents - the Constitution on the Liturgy - the final vote on it was 2,147 bishops in favor of it, and 4 opposed.
So I find it a bit hard to think that the vast majority of the bishops of the world were grossly mislead and deceptive, or they did not know how to vote (the matter had been voted on in part multiple times), or that there is confusing wording ( I have read it more than once and don’t find it confusing), or that, with the vast majority of bishops voting to adopt it as the official document of the Church, that it was not a TRUE Catholic Teaching. And it has been set forth as TRUE Catholic Teaching by 4 popes; Paul 6th, John Paul 2, Benedict 16 and Francis (I am leaving out John Paul 1 as he was not around long enough to express anything on the matter).
The alternative is to say that the vast majority of bishops, and 4 Popes, and the vast majority of Catholics have abandoned the TRUE Catholic teachings and are all in heresy, and that there is an extremely small remnant of Catholics who know the TRUTH. That sounds a little bit too much like Gnosticism.
