Well, there's Piers Paul Read and Torgny Lindgren. And Michael D. O'Brien.
I thought this remark, from the comments, interesting: "But seriously, a widespread reinstating of the Tridentine Mass is just going to bleed Catholic membership in most Western countries. It does seem alienating ..." Alienating? To whom? To the millions who buy CDs of Gregorian Chant or who go to see a film like Into Great Silence? Given the response I have been getting to my article yesterday, it looks to me as if a lot of people find it anything but alienating. Moreover, even if it did "bleed Catholic membership," that might not be so bad a thing. Numbers are less important than fervor.
