Most of what was in the actual Vatican II documents consisted of either meaningless feel-good re-statements of existing doctrine or vague but high-sounding statements that people probably thought would have no impact on anything. After all, Vatican II was NOT a doctrinal council, but a “pastoral council.”
It was just this very vagueness and the very fact that it was not a doctrinal council and hence did not have the rigorousness or authority of such a thing that gave the evil people in the Church their opening to take it over and use it as they wished. Unfortunately, a lot of their thoughts and actions were accepted (or imposed) as reflecting the authentic meaning of the Council.
I think a lot of what is being done now is an attempt to sort out what was actually part of the Council (very little, in the end, I’ll wager) and what has been its conscious and wilfull misstatement for over 40 years.
Personally, I think the only thing that will finally have to go is the Novus Ordo mass. That was a last-minute, completely unexpected imposition by the Bugnini forces, and I think everybody realizes that it has significant theological weaknesses. I don’t think the Pope is going to reinstate the old Mass, but I do think the influence of the SSPX and others, even the entering Anglicans, is going to give him the ability to confront at the thing that has symbolically and actually been the problem for 40 years - the Novus Ordo mass.
It was not only unsatisfactory in itself and its theology and history, but it gave rise to many abuses and carried them on throughout time.
It depends what it stands for. SSPX is correct in asking to clarify that. If the Novus Ordo stands for diluted fuzzy at the edges Catholic ecclesiology, indifferentist ecumenism and bottom-up redesign of the flow of authority in the Church, then those underlying errors have to be exposed as well. If, on the other hand, the Novus Ordo Mass is merely an unfortunate set of rubrics, then it will fade away by itself now that the traditional forms are encouraged.
