On December 12, 1531, a miracle happened in Mexico. A poor Indian, Juan Diego, was walking on a lonely road north of Mexico City, looking for water for his uncle. He was surprised by a vision of a beautiful woman who directed him to a spring of fresh, cool water. In the same spot a few days later, the vision appeared to Juan Diego again. This time, she told him to go Mexico City to tell the high church officials to build a church in her name on that site. But why would the ecclesiastical officials believe the poor Indian man? Surely the Virgin Mary would not appear to someone so lowly. They insisted on proof.
