I'm curious. Have your ever read "Reform of the Roman Liturgy" by Msgr. Klaus Gamber (it has an introduction by Cardinal Ratzinger, in case you're worried it's schismatic). If not you might want to look into it. Lots of information about the Novus Ordo, how it was created, what came before, and how faithful the reformers were to what Vatican II called for.
Incidentally, Gamber does not reject the Novus Ordo. He simply points to problems in the way it was created, and examines the history of how it came about.
In any case it will give you some insight into the mind of those who feel the Novus Ordo reform was not the same thing as the Tridentine reform.
<>Yes, I read it when it first came out. I think I loaned it to another and I never got it back. I have lost many books that way....<>
You correctly point out that Gamber didn't reject the Novus Ordo--but you fail to mention that this was only because it would be unworkable to do so now that it was so firmly established. He abhorred it as a liturgy and cited it as a major reason for the Church's post-conciliar decline. He called it a "frightening" development.
