The French bishops of the Ecclesiastical Province of Besançon and the bishops of Strasbourg and Metz sent a snarky note to Pope Benedict XVI to communicate their complaints (the Italian daily Il Giornale called "lamentele… grumblings") about the establishment of the Bon Pasteur Institute in Bordeaux and a possible a Motu proprio to derestrict the "Tridentine" Mass. In their statement they write:
Considering as they do that the liturgy is the expression of the Church’s theology, the bishops fear that the entry into general use of the Roman Missal of 1962 will call into question the direction taken by the second Vatican Council. Such a decision also has the potential to cause harm to the unity existing between priests, no less than that between the faithful.
Am I getting something wrong here? Wasn’t the 1962 form of Mass precisely the Mass that nourished, accompanied, shaped and underpinned the Second Vatican Council? The 1962 Missale Romanum gave the Council its direction and the previous editions shaped all the the bishops of the Council. There is no discontinuity between the Council and the 1962 Mass.
This is why wider use of the old Mass will help us with the newer form of Mass and with richer understanding of the texts of the Council. There must be continuity with the past before a direction can be plotted for the future.
