A chronological list of Popes in order from Pope John VI to Pope Leo III, with attached portraits. During this time, Pope Constantine would be the last Pope to visit Greece until the year 2001. Reigning from the Vatican as the head of the Roman Catholic Church and the Bishop of Rome, it is the Pope's God-given duty to spread the gospel of Jesus throughout the Holy See and interpret God's divine will so Catholics may enter the Kingdom of Heaven. Many Popes were granted sainthood and are celebrated to this day.
