Poor Cardinal Gregory! He is afraid to mention that nearly 90% of the participants at the recent World Youth Day want the TLM to be left alone.
Reading the Concilium document that was the basis for Monsignor Bugnini and his attempt to create a new mass, the Latin Mass, the Latin language for the mass, and the Gregorian Chant at mass were NORMATIVE. Even Archbishop Lefebvre voted in favor of that document. The Novis Ordo mass was to be the EXTRAORDINARY mass. Mass in the vernacular came about in part because one country requested the use of the vernacular. When that was granted by Paul VI, many countries then made the request, and Paul VI granted each request, then declared the vernacular could be applied with papal permission. Both Popes Saint John Paul II and Benedict XVI called (erroneously in my opinion) the TLM mass the Extraordinary form of the mass.
One final point. While the Bugnini effort was underway, the Catholic pariti were able to meet, when out of the official sessions, with six Protestant “pariti,” from Methodist, Episcopalian, Anglican, Luthern, and Calvinist rites, the results of whose efforts we see today in the Novis Ordo mass. Their participation was memorialized with an article together with a picture of the six with Pope Paul VI in the L’Ossevatore Romano of April 23, 1970.
