Fr. Zuhlsdorf over at What Does the Prayer Really Say? has this poll on whether "hard core" traditionalists think the novus ordo is valid or not.
So far the obvious answer is prevailing: Yes, it is valid.
The poll is in response to the outrageous and ignorant comment of William Oddie from the Catholic Herald, who wrote: "SSPX actually demands that Rome should repudiate the Council and accept that the Mass of Paul VI is invalid, even Protestant."
This statement is so off the mark it makes one wonder why the Catholic Herald considers Mr. Oddie competent enough to comment on any thing pertaining to Catholicism, much less the SSPX or traditionalists.
I have never met an SSPX priest who thought the novus ordo was invalid. I have known some sedevacantists who held this opinion, but not among the SSPX or other traditionalists groups.
If it was invalid, then why would we care? Do we care about Lutheran services, or Anglican services, or Methodist services?
Is it Protestant? Yes and no.
The novus ordo isn't Protestant, per se. After all, it is a Catholic rite belonging to the Catholic Church. However, that does not mean it isn't Protestant in conception. In fact, it is an objective and discernible fact that it is almost a word-for-word copy of the 1959 Calvanist ritual of the Taizé community. This is what traditionalists mean when they say the novus ordo is "Protestant". Mr. Oddie, though, probably doesn't have the research skills to even look up the word "Taizé" on Google, so, of course, he wouldn't know this.
From the ignorance of the neo-cons, libera nos, Jesu!
