As far as the future of the Catholic Church is concerned, your generation is nothing more than an anomaly of the post-WW2 era that will simply be belched into oblivion within a few decades. By the time you are gone, nobody is really going to know that there ever really was a "progressive" movement in the Church.
The "new fogeys" better figure out a way to change this.
Laymen don't care what kind of attire a priest prances around in. And they are not going to be deferential to him just because he wants it.
Cocksureness is a quality of youth, whether in the Church, or in business, or elsewhere.
They'll grow out of it.
That's like saying that by the time Lenin and Stalin were dead no one would remember that there had ever been a Russian Revolution. Very unlikely, especially when there are millions of corpses to testify to the reality of what occurred. Same thing with the Catholic Church. There are tens of millions of souls that have fallen away from the faith thanks to the revolution that has occurred since 1962. This is not something to be forgotten, but something to be taught to future generations as an object lesson in the catastrophes that occur when man usurps the place of God.
