After being elected and choosing his name, Pope Francis's first act was bestowing the Urbi et Orbi blessing to thousands of pilgrims gathered in St. Peter's Square. Before blessing the crowd, he asked those in St. Peter's Square to pray for his predecessor, "the bishop emeritus of Rome" Pope Benedict XVI, and for himself as the new "bishop of Rome".
