As Pope Leo XIV is formally inaugurated, he vows to work for unity so the church becomes a sign of peace in the world, with leaders including Vice President JD Vance and Ukrainian President Volodymyr Zelensky in attendance.

Pope Leo XIV has taken the reins as leader of the Catholic Church, and on Friday, May 9, started his first full day as Pontiff with a mass at the Sistine Chapel, during which he called his election both a cross and a blessing.
