Where does the authority of the pope come from for the catholic?

The authority of the pope in the Catholic Church is believed to stem from the apostolic succession, which traces back to Saint Peter, one of Jesus' apostles, whom Catholics regard as the first pope. This authority is reinforced by the belief that, through the Holy Spirit, the pope serves as the spiritual leader and teacher of the global Church, guiding its doctrines and practices. Additionally, the pope's role is supported by the tradition and teachings of the Church, asserting his position as the successor of Peter and the visible head of the Church on earth.
