The Pope is the world leader of the Catholic Church, and, at the same time, Head of State of the Vatican City. The first document that officially attests to the existence of a Pope commanding the Catholic Church is dated to the end of the first century, written by Clement I, who was the first Apostolic Father of the Church.
Today, the Popes dedicate themselfs to ecumenism, interfaith dialogues, charitable works and the defense of human rights. The Pope has authority over canonical and liturgical matters, it is he who determines what must be believed by the faithful. The Pope can also decide on judicial matters within the Church and on the executive function and he who makes the desired appointments. The work routine of the Popes involves more than 16 hours of daily activities and sometimes travels to Christian countries to spread Catholic doctrine.
