The Feast of Our Lady of Guadalupe
According to tradition, Mary appeared to a simple man named Juan Diego, in an area of Mexico on December 9, 1531. During her first apparition she requested that a shrine to her be built on the spot where she appeared, Tepeyac Hill (near what is now known as Mexico City). The bishop demanded a sign before he would approve construction of a church, however. Mary then appeared a second time to Juan Diego on December 12, 1531 and ordered him to collect roses. In a second audience with the bishop, Juan Diego opened his cloak, letting dozens of roses fall to the floor and revealing the image of Mary imprinted on the inside of the cloak—the image that is now venerated in the Basilica of Guadalupe.
