The term "Papal" refers to anything related to the Pope, the leader of the Roman Catholic Church. The Pope is considered the spiritual head of Catholics worldwide and has significant influence over church doctrine and practices. Papal authority is derived from the belief in the Pope's role as the successor to Saint Peter, one of Jesus Christ's apostles. Papal decisions and teachings are often communicated through official documents known as encyclicals or apostolic letters. These writings address various issues, including morality, social justice, and faith. The Papal office also plays a role in international diplomacy and interfaith dialogue, promoting peace and understanding among different religions.
