On July 7, 2007 Pope Benedict XVI issued as a motu proprio Summorum pontificum as well as a letter to the bishops throughout the world. In this letter the Holy Father states, “Furthermore, I invite you, dear Brothers, to send to the Holy See an account of your experiences, three years after this Motu Proprio has taken effect.”
And so, on May 13, 2011 the Pontifical Commission “Ecclesia Dei” will release a document entitled Universae ecclesiae to reaffirm the principles of Summorum ponfiticum and offer clarification on particular items.
Unlike columnists and bloggers who claim as much, I do not have a crystal ball. But we can prudently write that the document will add to the official corpus of writings which will endure time and this same document (I am led to believe) will not greatly or lightly shift the canonical or liturgical ground as did its older sister Summorum pontificum.
