The pope is assisted by the Papal Master of ceremonies who is almost always by the pope's side during liturgies. The current holder (2013) is Monsignor Guido Marini. The Master of Ceremonies is apponted by the pope for a 5 year term.
The Master of ceremonies is an official of the Papal Court responsible for the proper and smooth conduct of the elegant and elaborate rituals involving the Pope and the sacred liturgy. He may also be an official involved in the proper conduct of protocols and ceremonials involving the Roman Pontiff, the Papal Court, and other dignitaries and potentates. Examples of official liturgical books prescribing the rules and regulations of liturgical celebrations are Ceremoniale Romanum and Ceremoniale Episcoporum.
Pope John XXIII convened the Council and Pope Paul VI made the changes to the Mass.
The pope says mass daily, usually in his private chapel.
If you are present in the Vatican City during an address by the Pope, he will sometimes bless rosaries and other religious items you have with you. However, the Pope does not do a "mass-blessing" of rosaries to be sold in stores or online.
The Pope has allowed priests to celebrate three Masses on Christmas Day, the first Mass is at midnight, then one at dawn, and one during the day. The Mass at midnight is the very first Mass of Christmas.
Pope John XXIII was pope during 1962. He passed away the following year.
The pope's death removes him. There is no pope during the conclave that elects a pope.
Palestrina
The Latin mass officially was changed from Latin to the vernacular during the papacy of Pope Paul VI [September 26, 1897-August 6, 1978]. Paul VI reigned as Pope of the Roman Catholic Church and as Sovereign of Vatican City for 15 years, from 1963 to 1978. He approved the New Order of the Mass in the vernacular in April 1969. The changes were carried out the following year, in 1970.
The Easter blessing is given during the mass in St. Peter's Basilica in Rome that is celebrated by the Pope. He begins the mass by venerating the symbol of the Risen Christ.
His inauguration mass was held on April 24, 2005.
