The apparition of the Blessed Virgin Mary that came to be known as Our Lady of Guadalupe was a miracle. The Castilian roses that came from Tepeyac Hill in winter were a miracle. The divinely illustrated vision of Our Lady on St. Juan Diego's tilma was a miracle—as is the fact that the tilma composed of organic fibers has refused to degrade for 500 years and is still available to see to this day.
But none of those were the greatest miracle that Our Lady brought to the Americas that fateful century. Fr. Mike points out the incredible miracle that many people gloss over—but the one that makes an eternal difference.
