Pope Leo is installed as Bishop of Rome in Basilica of St. John Lateran

On Sunday, Pope Leo XIV assumed his role as Bishop of Rome by taking possession of the Saint John Lateran Basilica, the cathedral or throne of the Diocese of Rome.

By completing the final ceremony, the Pope completed the symbolic "taking possession" of four basilicas that signify full papal authority within Rome.

During evening Mass on the same day, the pontiff declared, "I am Roman."

He also highlighted the importance of listening and collaboration within the Church.

Pope Leo, the first American-born pontiff, has now completed the formalities to become the bishop of Rome after succeeding Pope Francis on May 8.
