The Office of Pope, also known as the Papacy, is the highest authority in the Catholic Church. It is held by the Bishop of Rome, who is considered to be the successor of Saint Peter and the Vicar of Christ on Earth. The Pope has the authority to make decisions on matters of faith and morals, and to appoint bishops and cardinals. He is also the head of the College of Cardinals, which is responsible for electing a new Pope when the current one dies or resigns.
