Not necessarily. Popes and several bishops, including your own, have spoken against the “rupture of continuity” that has been created since the council. The rupture is not a trademark of the FSSPX, nor of the FSSP or any of diocesan priests who celebrate the EF, for that matter.
If you want to argue this rupture started long before the council, I will not disagree with you there.
You hit upon a salient point.
It is beyond simplistic to label it all Modernism, as Modernism at its heart is atheism disguised. Most of what went on after Vatican 2 had a lot more to do with the cultural changes going on in Europe and North America. In part, it was a reaction to what was widely seen as oppressive authoritarianism, both in the secular world and the Church. Looking at the movements that sprang up in society, including the rash of (IMHO brainless) theories in some areas of psychology, as well as politics, and the downward spiral of sexual morality all had an impact not only on those sitting in the pews, but also in the priesthood. Experimentation became the mind set; all the “old” was going to be thrown off and the “new” was the exciting adventure. Academia had its share of blame.
People prefer to take shortcuts. That is nothing new in history; it is part of the human reaction to just about anything. A tremendous number of people never actually read the documents of Vatican 2; but they talked with one another; met in groups, followed the newest “guru” and took mental and emotional shortcuts rather than doing the hard work.
Those who blame the documents are beyond narrow sighted, as they only look at Western Europe and North America as exemplifying how the documents “shook up the Church”. I would posit that a tremendous amount of the rupture was driven by culture and a combination of economic and political freedom.
Why? Look at Poland. The Church there was under siege from the Communists. And yet a “progressive” came back from the Vatican 2 meetings, and proceeded to lead the clergy, and through them, the laity, to a much more effective and far faster actual implementation of the documents. People are rapid to blame the “progressives” of Vatican 2 for the chaos; but a leading “progressive” lead a country in a way that avoided all of the chaos.
The milieu in Poland was vastly different in almost all aspects, as compared to Europe and North America. We had freedoms Poles only could dream of; but, I would submit, we abused those freedoms, both secular and religious, to no end. The Poles had no such “luxury”.
Secularism, hedonism, and all the other “isms” afoot in the 60’s, 70’s and beyond, had far, far more to do with how members of the clergy, and the laity, reacted to Vatican 2, and in particular as a supposed indicator of Church direction (absent any reading of the actual documents), than did the actual documents, the thought and impetus that lead to the calling of the Council, and the desires of the Church Fathers - bishops and Cardinals and the Pope.
John 23rd, and Paul 6th had no intention of reinventing the Church. However, a large number of clergy and behind them, laity, did decide, absent any questions, that those two Popes and the bishops of the world did. Any reading would indicate that those societies were inventing something out of whole cloth.
And thus we get a reaction, about as mindless as the reaction of the pseudo progressives in Europe and North America, to overthrow Vatican 2.
Neither side has the common sense to come in out of the rain, let alone slow down and actually see what the 2 Popes and the bishops of the world were trying to accomplish.
