Mr. Caulfield (I like your choice of avatar, by the way),
I think everyone who has posted thus far has offered some good, solid responses as to why a Third Vatican Council to “make it more like it was at the time of the Council of Trent” or do away with certain reforms of Vatican II would not be a good course of action. Let me make it clear that I probably sympathize with a lot of your desires for how things should be in the Church as opposed to how they actually are today, for example with kneeling for Communion and wider access to the TLM. Personally, I usually only attend the Traditional Mass, and I tend to have a very traditional mindset regarding Catholic doctrines on faith and morals.
That being said, it is my firm belief, from things I’ve read on these forums and in other publications, that the Church by its very nature cannot “go back in time,” so to speak, or adjust itself to how it was in an earlier era.
The Church is constantly moving forward through history, toward her end point-Judgement Day. To take one arbitary point in history (such as the time of Trent) and absolutize it as the Perfect Catholic Age is essentially fundamentalism. Catholics are not fundamentalists. And as others have noted, the Church has its sins and its struggles in every age.
But “moving foward” does not equal “changing doctrines.” It does mean that some customs and disciplines will change or be dropped, fasts will be made more or less rigorous, etc.
For one thing, if we never moved foward, in Mass we wouldn’t have the Elevation of the Host after the Consecration! Nor would I ever want this particular part of the Mass to be done away with, because I think it so clearly expresses Catholic faith in the Real Presence of Christ among us.
But I think the proper way to view the customs or elements of the liturgy whose value we believe so strongly in is that they are so valuable not because they are the product of a particular age, but precisely because of that inherent, obvious value that makes them timeless and therefore appropriate in any age. All of the This therefore implies that there could be, at some point in the future, a change in the liturgy that more clearly brings out and visibly expresses a truth of Catholic faith. I don’t want to start suggesting changes because I don’t have any good ones; I doubt most people do.
All of the traditional priestly societies, like the FSSP, make the point that the desire to have wider access to the TLM for all the faithful is not motivated by nostalgia for a bygone era, but because we believe this Mass is part of the Church’s Living Tradition, because it is timeless.
