Pope Leo XIV led a Rosary for peace with children at the Grotta della Madonna di Lourdes in the Giardini Vaticani on October 1, 2026. The event launched the "Un milione di bambini recita il Rosario" initiative organized by Aiuto alla Chiesa che Soffre.
The Pope invited children worldwide to pray for those living in conflicts and difficulties. He described the effort as fifty million Ave Maries intended to unite all continents, races, and nations. He also recommended accompanying prayer with gestures of love and good works.
