The Pope is the head of the Roman Catholic Church in the Toaru Majutsu no Index series.

His name is currently unknown but what is known about him is that he was a friend and a former disciple of Fiamma of the Right before becoming Pope. Unlike a lot of popes in the real world this pope feels that he's disconnected from the people outside the chapel and wonders why's that so. When the magic world learns of the existence of Touma and his powers, Fiamma convinced the Pope that Touma is a heretic and his powers are a threat to the world, The Pope declares him a Heretic that must be eliminated. When the Pope later learns that Fiamma had manipulated him all this time, Fiamma casts a powerful spell to destroy the Vatican but the Pope manages to divert the spell onto himself to save the city. After his recovery he sets out to stop Fiamma and his plans.
