Report from Catholic World News:
Informed sources at the Vatican have confirmed reports that the Holy Father regularly celebrates Mass using the 1962 Roman Missal.
In his motu proprio Summorum Pontificum the Pope says that the older form-- the form in universal use before the liturgical changes that followed Vatican II-- was never abrogated.
Since becoming Roman Pontiff, Benedict XVI has always used the new ritual-- which he identifies in Summorum Pontificum as the "ordinary form" of the Roman rite-- for public celebrations of the Eucharistic liturgy. However few people have witnessed the Pope celebrating his private daily Mass.
I'd like to spontaneously ask the Holy Father to be able to attend.
