Returning home, the Indian found his uncle ill, and the next day, he had to stay at his bedside to take care of him. As the illness got worse, the uncle asked his nephew to go look for a priest. At dawn on Tuesday, December 12, Juan Diego started on the road to the city. Approaching Tepeyac Hill, he thought it best to make a detour so as not to meet the Lady. But suddenly, he perceived her coming to meet him. Embarrassed, he explained his situation and promised to come back when he had found a priest to administer last rites to his uncle. "My dear little one," replied the Apparition, "do not be distressed about your uncle's illness, because he will not die from it. I assure you that he will get well... Go to the top of the hill, pick the flowers that you will see there, and bring them to me." When he had arrived at the top of the hill, the Indian was stunned to find a great number of flowers in bloom, Castillian roses that gave off a very sweet fragrance. Indeed, in the winter, the cold allows nothing to survive, and besides, the place was too dry for flowers to grow there. Juan Diego gathered the roses, enfolded them in his cloak, or tilma, then went back down the hill. "My dear son," said the Lady, "these flowers are the sign that you are to give the bishop... This will get him to build the church that I have asked of him."

Juan Diego ran to the bishop. When he arrived, the servants made him wait for hours. Amazed at his patience, and intrigued by what he was carrying in his tilma, they finally informed the bishop, who, although with several people, had him shown in immediately. The Indian related his adventure, unfolded his tilma, and let the flowers, which were still shining with dew, scatter to the floor. With tears in his eyes, Bishop Zumárraga fell to his knees, admiring the roses from his country. All of a sudden, he perceived, on the tilma, the portrait of Our Lady. MARY's image was there, as though printed on the cloak, very beautiful and full of gentleness. The bishop's doubts gave way to a sure faith and a hope filled with wonder. He took the tilma and the roses, and placed them respectfully in his private oratory. The next day he went with Juan Diego to the hill where the apparitions had taken place. After having examined the sites, he let the seer return to his uncle's house. Juan Bernardino had been completely cured. His cure had taken place at the very hour when Our Lady appeared to his nephew. He told him, "I have also seen her. She even came here and talked to me. She wants a church to be built on Tepeyac Hill and wants her portrait to be called 'Saint MARY of Guadalupe.' But she didn't explain to me why." The name "Guadalupe" is well known by the Spanish, because in their country there is a very old sanctuary dedicated to Our Lady of Guadalupe.
