Pope Leo XIV celebrated his first Easter Mass as pontiff with a call Sunday to lay down arms and seek peace to global conflicts through dialogue. He departed, however, from a tradition of listing the world's woes by name in the Urbi et Orbi blessing from the loggia of St. Peter’s Basilica. Leo, the first U.S.-born pope, emphasized Easter’s message of hope as a celebration of Jesus’ resurrection after being crucified, in both the blessing and his homily.
