You mean like some of the liturgical reforms made by Pius X? He made a few of them.
St. Pius X’s reforms did not come from a growing movement of theologians who, despite papal warnings, continue to push ideas of ecumenism and modernism. His reforms, whatever you think of them, were based on different ideals entirely. The major players (not behind the scenes, but actual major players in the Consilium that made major changes to the liturgy) like Bugnini, Bouyer, Jungman, Braga, and so on, very expressly stated that the new ecumenism of removing things distinctly Catholic was part of their goal. They also wanted to (and mostly succeeded in removing) negative things like sin, death, judgment, hell, and so on.
Yet it was all ratified, and the Form of Mass is now the Ordinary. Our last two Popes signed off on the V2 documents, as did a certain French Archbishop. There is nothing in V2 which is contrary to Catholic teaching, Rome has said so.
People can say what they want, and make their commentaries. Including commentaries that misquote people.
I acknowledge V2 is not actually heretical. But it’s problematic. I could take Aquinas’ Summa and take out everything on hell, transubstantiation, judgment, heresy, and other things that are too distintively Catholic or too negative. Then I could re-write maybe 60% of the stuff on God’s Love and the Trinity, replacing it with simpler, or even extremely simple, drivel that isn’t wrong but leaves out majesty, leaves out beauty, but makes things very accesible to all, even with no education, no experience, and even for non-Catholics. I could add a few nice little things about sharing and caring.
That would an “OF” equivalent to the Summa. By my description, there would be no heresy in it. But it would no longer fight heresy as the Summa does, and it would not meet the real needs of the faithful.
The architects of the new Mass also frequently talked about the needs of “contemporary man” to justify removing things from the TLM about corporal mortification, hell, sin, dangers of heresy, enemies of the Church and so on. Well first of all the psychological approach is a problem because the Mass isn’t about psychology but secondly, the psychology is wrong. It is precisely because “contemporary man” isn’t interested in or thinking about those subjects that he needs to be confronted with them.
In the Mass, yes. But also the Vatican 2 documents make it easy to justify such changes.
Given what was happening in the world, we actually needed another Trent-like council, that recodified and strengthened and clarified and implemented the vision of Trent, and Vatican I which was interrupted. We didn’t get that :-(.
