Our Lady of Fatima in 1913 asked the children in Fatima, Portugal to pray for peace. War in Europe was imminent, and it soon became World War I. War after war continued through the rest of the 20^th century and into the new millennium. Rumors of World War III are in the air. Will Mary’s children—that’s all of us—ever learn to pray and work for peace? On this memorial of Our Lady of Fatima, I need to pray most fervently for an end to war in Ukraine, Gaza, and in many other parts of the world. I need to heed Mary’s message at Fatima. Mary, my mother, teach me. Our world keeps forgetting your lesson.
