In the interesting Italian newssite L’Occidentale there is a piece by Pietro de Marco about why Pope Benedict XVI would want to derestrict the older form of Mass.
It is as if this fellow had been reading my articles. Actually, the similiarity between his ideas and mine are probably due to the fact that we are working from the same sources, which are certainly, knowledge of the older liturgy and the writings of Papa Ratzinger.
Here is a brief summary of the reasons de Marco thinks Pope Benedict would want to derestrict the older Mass. They are fleshed out with my own observations. I have other reasons beyond de Marco’s, but here are de Marco’s with my own additions.
a) An uncommon language gives an impression of the rite’s antiquity. In turn this supports a perception of continuity with the past.
b) Prayer "turned toward the Lord", because of the operating principle lex orandi lex credendi will stimulate relfection about what is sacred and redirect us to the first condition of Mass, namely, that it be a sacrificium. It is not the behavior of the congregation that counts. The High Priest is the one who is in action. This reattachment to the sense of mysterium will work against the pragmatic and activist liturgical attitude prevalent today. Mass is mystery and sacrifice, not spectaculum.
c) The Blessed Sacrament is at the center. Recovering this sense of presence will aid a dialogue with the "God with us", which has long been a point of reflection for Joseph Ratzinger in years past, and today.
Again, these are de Marco’s reasons supplimented with my own thought.
I have a couple other reasons which I am working to formulate for an upcoming article.
