And this comes from the latest edition of the "ultra-Progressive" French weekly Golias (tip to our friends at Messa in Latino), among other information we and MiL had already reported regarding the instruction on the implementation of the motu proprio Summorum Pontificum:
We have learned, from a direct Roman source, that this decree of application has indeed undergone a double correction. At the beginning, it has ben prepared by Mgr. Guido Pozzo, secretary of the Pontifical Commission « Ecclesia Dei », in charge of the matter. Subsequently, Cardinal Levada and his faithful adviser, Mgr. Charles J. Scicluna, a Maltese, had strongly amended the text in a restrictive sense. With the agreement of Cardinal Cañizares Llovera, Prefect of the Congregation for Divine Worship! Our recent information had thus been precise. [Rorate adds: so had ours.]
Once it had been modified by Levada, the document arrived at the Pope's office. And the latter would not have been pleased with the about-turn that had taken place. It [the draft] was thus replaced, more or less, by the document as it had originally been written by Guido Pozzo. [That is,] In a sense that is more favorable to Traditionalists.
So many things make sense in Golias's account - and dovetail perfectly with what we know - that we give it great credence, though it is still a collection of internal rumors almost impossible to verify with certainty. Our thanks to all who have prayed for this and signed the Petition.
