If you don’t know anything about apparitions of Mary, you may not know about some powerful stories. Inevitably, the “certified” visions appear only to children or people who have no power in society. As an example, Our Lady of Lourdes appeared to a young girl who was illiterate, yet was able to repeat what the lady said, that she was the “Immaculate Conception.” There was no way that young Bernadette, far removed from the theologians of her day, could possibly have known they were all kicking around the idea of Mary’s immaculate conception and whether or not it was true. No one in the village really knew about that going on. Later, in Fatima, Portugal, “a lady” appeared to three shepherd children. One day, she made the sun dance. The weirdest part about the sun dancing was that not everyone there saw it, which seemed to make it even more believable as divine (Bible stories inevitably have unbelievers seem to not see a thing).
But the big common denominator inevitably is: a silenced voice sees a lady (the viewer or viewers rarely call her Mary, but eventually they figure it out or someone else will eventually decide it is she).
Today is the celebration of Our Lady of Guadalupe, Our Lady of the Americas (not just Mexico, as some might believe).
