As authentic Marian apparitions go, many of the aspects of our Lady’s appearances to the three shepherd children in Fatima a century ago seem commonplace: Mary asks the seers to pray and do penance for the conversion of sinners, calls them to daily devotion to the Rosary, advocates for peace in the world, requests the children to return on specific dates, and entrusts them with secrets.
What has never ceased to surprise me, on the other hand, is what she revealed to the children after she had showed them a very vivid vision of hell.
