I don’t think the Pope wants to create yet another division in the Church. I think this is a further step towards eliminating the Novus Ordo. I love the term Gregorian Mass or rite, btw, because it simply eliminates all the ambiguities over the term “Tridentine,” the description “Latin,” etc. and also takes it out of the clutches of the self-appointed monitors of orthodoxy (who, while some of them must be thanked for heroically standing up to the modernists, can also be quite bitter and nasty and would probably drive people away). We’re making a fresh start, in other words.
I think this is really exciting news. My only concern was that perhaps this wasn’t exactly what Castrillon meant to say. However, I think the Pope or somebody else at the Vatican recently used the term “Gregorian Mass,” so it’s clearly something they’re discussing.
You might be right about Benedict’s true motives. It would be a more “streamlined” approach to simply phase out the N.O. Still, making the change from “Form” to “Rite” not even a year after the promulgation of the Motu Proprio certainly allows one to think of the possibility of two Rites eventually existing side-by-side in the Western Church, with the common-sense of a better-catechized future generation left to sort out which one will prevail in the long run.
