Pope Paul VI said, rather explicitly, that the 1970 Missal is not a “New Mass”:
Yes, there is a twinge of “hopeless optimism” in this Address by the Holy Father. But I think the gist of it is true: the
Missa Normativa is not, in and of itself, essentially different from the
Missa Tridentina.
I would agree that it is flawed
only insofar as 1) there is way too much room for variation; 2) vernacular translations stink; 3) related to [1], Latin and Gregorian chant are only “highly reccomended options.”
When celebrated in a traditional manner, it’s still the same Mass.
And yes, the word “Tridentine Mass” is a misnomer; the difference is Novus Ordo has begun to acquire some negative connotations, so more and more people seem to be using the phrase
Missa Normativa, as the Cantians do in their Rule.
