In a festive St Peter’s Square, Pope Leo XIV led his first Regina Coeli, urging prayers for vocations, peace in Ukraine and Gaza, and honoring Mother’s Day with warm wishes to all mothers. Entrusting it all to Mary, Queen of Peace, he renewed the plea: “Never again war.”

Pope Leo XIV has urged journalists to be peacemakers, rejecting prejudice and anger in their reporting.
