The office of the Master of Ceremonies itself is very old. The Master of Ceremonies is an official of the
Papal household 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
Cæremoniale Romanum and
Cæremoniale Episcoporum. The role of the master of ceremonies is outlined in the
Ceremonial of Bishops, Nos. 34–36. According to the
Catholic Encyclopedia, the most ancient ceremonials and rituals of the Catholic Church are the
Ordines Romani. Names of Masters of Ceremonies are known since the late Middle Ages (15th century) and the
Renaissance (16th century). However, copies of books prescribing the forms of rituals, rites and customs of pontifical ceremonies are known to have been given to
Charles Martel in the 8th century. The rules and rituals themselves are known to have been compiled or written by the pontifical masters of ceremonies, dating back to the time of
Pope Gelasius I (492–496) with modifications and additions made by
Pope Gregory the Great (590–604). According to the
General Instruction of the Roman Missal, "It is desirable, at least in cathedrals and in larger churches, to have some competent minister or master of ceremonies, to see to the appropriate arrangement of sacred actions and to their being carried out by the sacred ministers and lay faithful with decorum, order, and devotion." The Master of Ceremonies may also have responsibility for the physical security of the place of worship during the liturgy, and be familiar with appropriate procedures in case of a medical emergency. The Master of Ceremonies coordinates with any concelebrating priests, deacons, altar servers and sometimes the lectors and music ministers to ensure each knows when and how to perform their liturgical functions. At major festivities such as Christmas and Easter, when the liturgies are long and complex, the Master of Ceremonies plays a vital role in ensuring that everything runs smoothly. The current (2021-2026) papal Master of Pontifical Liturgical Celebrations is Archbishop
Diego Giovanni Ravelli, who succeeded Bishop
Guido Marini. (See the
