Pope

=== Residence and jurisdiction ===
The pope's [[cathedra|official seat]] is in the [[Archbasilica of Saint John Lateran]], considered the cathedral of the Diocese of Rome, and his official residence is the [[Apostolic Palace]]. He also possesses [[Papal Palace of Castel Gandolfo|a summer residence]] at [[Castel Gandolfo]], situated on the site of the ancient city of [[Alba Longa]].

The names "Holy See" and "[[Apostolic See]]" are ecclesiastical terminology for the [[ordinary jurisdiction]] of the bishop of Rome (including the Roman Curia); the pope's various honours, powers, and privileges within the Catholic Church and the international community derive from his Episcopate of Rome in lineal succession from the Saint Peter, one of the twelve apostles.<ref>see [[Apostolic succession]]</ref> Consequently, Rome has traditionally occupied a central position in the Catholic Church, although this is not necessarily so. The pope derives his pontificate from being the bishop of Rome but is not required to live there; according to the Latin formula ''ubi Papa, ibi Curia'', wherever the pope resides is the central government of the Church. As such, between 1309 and 1378, the popes lived in Avignon, France,<ref>see [[Avignon Papacy]]</ref> a period often called the "Babylonian captivity" in allusion to the [[Bible|Biblical]] narrative of Jews of the ancient [[Kingdom of Judah]] living as captives in [[Babylonia]].

Though the pope is the diocesan bishop of Rome, he delegates most of the day-to-day work of leading the diocese to the [[cardinal vicar]], who assures direct episcopal oversight of the diocese's pastoral needs, not in his own name but in that of the pope. The current cardinal vicar is [[Angelo De Donatis]], who was appointed to the office in June 2017.
