Pope Leo XIV's inauguration Mass will be held on May 18th at 10 a.m. in St. Peter's Square. Key changes from Pope Francis' inauguration include representatives of the people of God pledging obedience instead of cardinals. The ceremony will feature prayer at St. Peter's tomb, a procession with the pallium and fisherman's ring, the Gospel read in Greek and Latin, and the Pope's first homily outlining his ministry. The Mass symbolizes the start of his service as successor of St. Peter and Bishop of Rome.
