Interesting excerpts of an interview granted by the Master of Papal Liturgical Ceremonies, Mons. Guido Marini, to Italian daily Il Tempo (Sunday edition):
When shall we see Pope Benedict celebrating the Latin Mass according to the extraordinary Roman Rite, that of Saint Pius V? I personally viewed the 'motu proprio' as an act of liberality, of openness, not of closemindedness.[G.Marini:] "I do not know. Many faithful have availed themselves of this possibility. The Pope will decide, if he considers it appropriate."[...] The Pope, a year ago, celebrated Mass in the Sistine Chapel with his back turned to the people. Who it was who proposed it to him?[G. Marini:] "It was I who proposed it to him. The Sistine Chapel is a treasure chest. It seemed a strained effort to alter its beauty b y building an artificial, made-up stage. In the ordinary rite, this celebration 'with the back turned to the people' is a foreseen position. Yet I underline: the back is not turned to the faithful, but the celebrant and the faithful are turned towards the only point that counts, which is the Crucifix."
