From sede vacante to conclave: Key terms to know at the start of a papal transition

The start of a papal interregnum brings many terms that may not be familiar to many people, including many Catholics. Here are some of the key words and phrases that will be used throughout the interregnum, especially the conclave to elect the new pope.

Apostolic See or Holy See: The earthly heart of the Church is often referred to as the Apostolic See or Holy See. A see is a seat of authority, from the Latin “sede” for “chair.” Jesus said the Pharisees sat on the chair of Moses. Judges sit on a bench, representing the authority of the state. Professors hold chairs of academic authority. And in the Church bishops possess chairs of spiritual authority, which is why in part their dioceses are called sees. The Roman Diocese has been called the Apostolic See, or Holy See, from ancient times, as it is the seat of authority of the chief apostle Peter, who has Christ’s authority over holy things. The expression applies not only to the pope but also to those in Rome who assist him in governing the universal Church.

camerlengo: The camerlengo, or chamberlain, of the holy Roman Church has the key role of organizing the process during the vacancy of the Apostolic See, the interregnum. It is the camerlengo, assisted by the master of papal liturgical celebrations and other officials who certify the death of the pope. During the period of vacancy the camerlengo, assisted by the vice camerlengo, gathers reports from the departments of the Curia so that the College of Cardinals can manage the ordinary affairs of the Holy See until a new pope is elected. This is necessary since virtually all department heads lose their offices when a pope dies, except for the camerlengo, the major penitentiary, and the almoner of his holiness.
