The canonization of Francisco and JacintaPopularity of the Fatima apparitions spread, and the cause for canonization of Francisco and Jacinta was opened in 1946. Much of what is known about their life and holiness is known through Lucia’s memoirs.
“People may ask: ‘These children died so young, what do we know about them and their lives of faith?’ But a lot was related by Sr. Lucia and the witnesses of the apparitions. Francisco had a devotion to the Eucharist, and Jacinta wanted to help those who were suffering, that was her charism or focus after the apparition. Those are details most of us don’t really know about,” O’Neill said.
Francisco and Jacinta became the youngest non-martyr children to be beatified, on May 13, 2000, the 83rd anniversary of the first apparition. St. John Paul II presided over the Mass.
