Our lady of Guadalupe
Today's Feast remembers Our Lady's appearance to St. Juan Diego, and as she is Patroness of Americas, particularly Mexico. The miraculously blooming roses found by the now-Sainted Juan Diego were "Castilian Roses" (also called "Damascus Roses"), or Rosa damascena, which didn't grow in Mexico .
After the conquest, the Spanish rule of the natives was so severe that a bloody revolt was imminent. Bishop Zummaraga prayed for Our Lady to intervene to prevent an uprising, to reconcile the Spanish and the natives and to bring peace. It is believed that he asked that he would receive roses native to his homeland of Castile Spain as a sign that his prayer would answered.
On December 9, 1531, Our Lady appeared to Saint Juan Diego who was a recently converted Catholic. She asked him to go to the Bishop and request him to build a church for her on the barren hill of Tepeyac that is now part of Mexico City. Our Lady wanted to show her merciful love to all of her children. The prudent Bishop asked Juan to ask the Lady for a sign. Juan did so and Our Lady promised to give him the sign.
On December 12, Our Lady again appeared to Juan on Tepeyac Hill and told him to pick the Castilian roses which miraculously appeared there and bring them to the Bishop as a sign for him to believe her request. Juan gathered the roses into his tilma and brought them to the Bishop.
Juan opened the tilma to show them and, to everyone's astonishment, the Image of Our Lady appeared on it. The Bishop then built the church as Our Lady had requested and nine million natives were converted to the one, true faith within the next nine years. Human sacrifice ended in Mexico forever. Our Lady of Guadalupe, means Crusher of the stone serpent.
