The bishop of Rome is one of many titles held by the pope.
On his way to the St. John Lateran Basilica for the final steps to take on the role of bishop of Rome, the pope stopped at Piazza Venezia in the center of Rome to meet with the mayor of the city, Roberto Gualtieri.
Speaking before a crowd, Gualtieri said the city of Rome is ready to accompany the pontiff “to affirm the paradigm of a new politics,” and ended his speech by welcoming him: “We are happy that Rome is now your city,” as translated by Vatican News.
