A red mozzetta was just delivered to the Vatican today, ordered in a hurry just this morning at the famous Gammarelli's Church Tailor of Rome.
Tomorrow is expected the Mass for the "beginning of the Petrine Ministry of the Bishop of Rome" and in all likelihood (the only way to explain the rush order), ushering in the use of the mozzetta presumably in the ceremony that will receive the vows of obedience of the cardinals.
Some might think that we are making a big deal out of nothing, but at a more substantial level, we are reassured by the fact that Monsignor Guido Marini has been confirmed in his functions for this "opening" ceremony, coordinating the Franciscan friars of La Verna called to serve at the altar.
The Mass was preceded by the Laudes Regiae, will be in Latin, except the homily (in Italian), readings, responsorial psalm and prayers of the faithful, will be alternately in assorted languages, while the Gospel will be sung exclusively in Greek instead of in two sacred languages, as is normal in the most solemn papal ceremonies, it seems out of a desire to shorten the time of the ceremony and avoid redundancy. For the same purpose of brevity and simplicity, the offertory procession will be abolished (and this is good, considering the masquerades to which that ritual has given rise in the past).
The Offertory will have a four-voice motet by Palestrina, written for the coronation of the Popes: Tu es ovium pastor.
The singing of the Te Deum finally will close the liturgy.
