Catholic Truths are like the set of mathematical truths; they are absolutely immutable. The proposition 2+2=4 will always be true, no matter what the most famous, intelligent, internationally renowned physicist, mathematician, etc., would claim (the Timmy Turner episode notwithstanding!). In general, the axioms of arithmetic, geometry, etc., are absolute. A triangle on a flat surface will have its interior angles always sum to 180 degrees. This is absolute and unchangeable.
The same is true of Catholic dogma, both the extraordinary and ordinary Magisterium of the Church. That which is infallible is just that; all else is error to one degree or another, no matter who is promulgating it, the Pope included, and please note that this observation in no way discounts valid theological opinions. That which is infallible, even if portions of it are still not completely understood, still forms a set of immutable truths.
While I am certainly bothered by what Pope Benedict and his immediate predecessors have said and done, I do not get "too bent out of shape" over it. In some respects, I don't really care. It's enough for me that there are bishops, priests, and religious brothers and sisters who are professing the true Faith, those immutable truths.
With Vatican II, one can bend it to make it fit with Catholic Tradition, but the point is that one does not have to. We are certainly seeing this in the area of "religious liberty," ecumenism, etc. That is the problem with the documents; they are ambiguous so that conservatives could read them one way, liberals another, with each side claiming "victory." But, does it matter, if there really are immutable truths?
Does Rome really care about traditional Catholics and priests? In one sense, not really. We make up such a small minority in the Catholic (sic) world. What they do care about, I think, is our presence on the Internet, because anyone with partial brain function can see for himself/herself that what the Church is teaching (or at least practicing) now is not what the Church taught in times past. "If you were right then, we are right now; if you were wrong then, you are wrong now," a great quote expressing the existence of immutable truths.
What the Vatican does care about is traditional Catholics causing problems, ruining the "progressive" agenda of those who wish to advance ecumenism, religious liberty, fraternity, or any of the other modernistic heresies which liberals take from their "reading" of Vatican II. Traditional Catholics are like the wild horses on the American plains, "raising hell" for the established ranchers. They want us "penned up" in the fold where we can have "our reading" of Vatican II while they continue to advance their modernistic heresies. Eventually, if we cooperate, they will use a "divide and conquer" strategy, eliminating us one by one. But, does it matter if we do not give in no matter how small (or large) we become, especially if we continue to believe, profess, and especially, preach those immutable truths.
Does it all matter? In a sense, no; just because Pope John Paul II or Pope Benedict XVI may end-up in Hell does not mean that any of us have to join them there, does it? So, they are free to practice and spread their heretical ideas, and we will continue to practice and spread the Catholic Faith. I am content with that; I guess that it's the best that I can do, because, in the end, I firmly believe that there are immutable truths.
Ultimately, what does matter is that there is Truth, and in the end, Truth will prevail.
