The Press Office releases a video message by Pope Leo XIV ahead of the 100th World Mission Day, to be celebrated on 18 October 2026 on the theme "One in Christ, united in mission". The Pope thanks God for the fruits of the Day instituted a hundred years ago by Pius XI and recalls his own personal experience as a missionary in Peru, stating that "the prayers and offerings of the faithful encouraged and sustained" his missionary work. He renews his invitation to support the Pontifical Mission Societies generously and to contribute, each according to his or her own vocation, to the Church's evangelizing mission toward the poorest.
