[quote=theMutant]The short answer is none. “Tridentine” refers to the form of the mass established by Pope St. Pius V after the Council of Trent. This mass underwent various minor changes over the centuries and the last Missal of that form is that of 1962. John Paul II has asked that the bishops provide an indult (permission) for those who are attached to this mass.
I also love this mass but it is not available in my archdiocese except at sedevacantist (those who don’t accept that John Paul II is a valid pope) churches so I won’t go there. I have also participated in a Latin Mass of the 1972 missal but the huge number of options made it very difficult to follow in the Latin.
None is the right answer; if it’s an “indult” Mass it’s according to the 1962 Roman Missal. While it is often named for the Council Trent (Tridentine), the Council did not make major changes to the Latin Mass in effect prior to the Council. As I recall, it standardized the Mass, which could just as well be called Gregorian (after Pope St. Gregory the Great)…so this Mass is basically over a millenium and a half old.
Also, the Latin Mass website lists a weekly Latin Mass in the Archdiocese of Seattle:
St. Joseph Chapel/Josephinum Hotel
1902 Second Avenue
Seattle, WA 98101
Sun. 9:30 a.m.
Maybe that would work for you.
