瑪利亞遂說： 「我的靈魂頌揚上主，我的心神歡躍於天主， 我的救主。」
在1531年12月9日，聖母在墨西哥城的台培亞的 (Tepeyac) 小山上顯現給一個57歲貧苦的印第安人；他名叫若望迪戈 (Juan Diego)，是當地少數的天主教徒。
Mary set out and traveled to the hill country in haste to a town of Judah, where she entered the house of Zechariah and greeted Elizabeth. When Elizabeth heard Mary's greeting, the infant leaped in her womb, and Elizabeth, filled with the Holy Spirit, cried out in a loud voice and said, “Most blessed are you among women, and blessed is the fruit of your womb. And how does this happen to me, that the mother of my Lord should come to me? For at the moment the sound of your greeting reached my ears, the infant in my womb leaped for joy. Blessed are you who believed that what was spoken to you by the Lord would be fulfilled.”
And Mary said: “My soul proclaims the greatness of the Lord; my spirit rejoices in God my savior.”
Although there had been Franciscan missionaries ministering to the Mexican locals in the sixteenth century, Christianity was not that popular among the locals at first. The locals worshiped idols and even practiced human sacrifices.
On December 9th, 1531, the Blessed Virgin Mary appeared to a poor Indian farmer Juan Diego on Tepeyac Hill while he was on his way to Mass to celebrate Mass. He was a humble man and one of the first baptized Indians.
In order to help the bishop believe what this humble farmer said about her apparition, and to have them build her a church, Mary showed them a number of miracles, including blossoming roses and flowers on a barren hill, and printed her portrait on the tilma that Juan used to carry the roses to the bishop. Juan's seriously ill uncle was also miraculously healed, and told Juan that a beautiful lady appeared to him and told him her name: Guadalupe.
Words about these miracles spread quickly; within a short time six million Indians were baptized, which very soon made Catholic the dominant religion in Mexico. It is still so today.
The portrait on Juan's tilma is still being displayed in the Basilica of Our Lady of Guadalupe, making it the most visited Marian shrine in the world. In 2002, Pope John Paul II set December 12 as the Feast of Our Lady of Guadalupe.
Through the Blessed Virgin Mary's apparitions, God is again showing His love for all people, and continue to transform the hearts of those who believe.
