By Catholic News Agency In 1531 a "Lady from Heaven" appeared to Saint Juan Diego, a poor Indian from Tepeyac, a hill northwest of Mexico City. She identified herself as the Mother of the True God and instructed him to have the bishop build a church on the site. As a sign for the bishop, she left an image of herself imprinted miraculously on his tilma, a poor quality cactus-cloth. The tilma shows no sign of decay.
An incredible list of miracles, cures, and interventions are attributed to Our Lady of Guadalupe. Each year an estimated 10 million people visit her Basilica, making her Mexico City home the most popular Marian shrine in the world, and the most visited Catholic church in the world after Saint Peter’s Basilica in the Vatican.
The Feast of Our Lady of Guadalupe is celebrated on Dec. 12. In 1999, Blessed John Paul II, in his homily given during the Solemn Mass at the Basilica of Our Lady of Guadalupe, declared the date of Dec. 12 as a Liturgical Holy Day for the whole continent.
