His Holiness Pope Benedict XVI issued today (Saturday, July 7, 2007) a motu proprio — entitled Summorum Pontificum — permitting the universal celebration of pre-Vatican II Mass, also known as the Tridentine Mass. (“Tridentine” is the adjective form of “Trent” and the Mass is so called because it was promulgated by the Council of Trent.)
This is seen as a major triumph by Catholic conservatives/traditionalists and those who love the pomp and ceremony of Tridentine Masses.
More commentary after I read the document. (For more information now, I encourage one to visit the blog Whispers in the Loggia.)
