The Office for the Liturgical Celebrations of the Supreme Pontiff (Latin: Officium de Liturgicis Celebrationibus Summi Pontificis) is that section of the Roman Curia responsible for organizing and conducting liturgies and other religious ceremonies performed by the pope of the Catholic Church. It is headed by a "master" appointed for a term of five years.
The Office and the consultants who advise it support the pope in expressing his interpretation of the liturgical modifications instituted following the Second Vatican Council. Popes have at times supported post-Council reforms, restored earlier practices, and introduced further innovations. When Pope Francis named five new consultants in September 2013, he included none of those appointed by Pope Benedict XVI, who were known to promote a return to pre-Council liturgical practices. Benedict restored pre-Council elements to the rite for the canonization of saints and Francis removed them and further shortened the ceremony. Guido Marini, the Master when Francis instituted his changes, is known as a traditionalist, but performs to the pope's instructions. In the words of one journalist, his job is "to thread papal preferences into the pageantry". For example, he works to ensure that liturgical music is integrated into the liturgy as Francis prefers, so that participants are never forced to wait for music to conclude before proceeding.
List of Masters of Pontifical Liturgical Celebrations
As well as assisting the Pope at sacred functions the Papal Master of Ceremonies also assists Cardinals on various occasions: during Consistories, when taking possession of his Titular Church, and during solemn celebrations of Mass or other important religious services. When a Cardinal is created at a consistory, the Master of Papal Liturgical Celebrations assigns one of the Office's Masters of Ceremonies to him.
