Juan Diego, as a devout neophyte, was in the habit of regularly walking from his home to the Franciscan mission station at Tlatelolco for religious instruction and to perform his religious duties. First apparition: at dawn on Saturday December 9, 1531 while on his usual journey, he encountered the Virgin Mary who revealed herself as the ever-virgin Mother of God and instructed him to request the bishop to erect a chapel in her honour so that she might relieve the distress of all those who call on her in their need.
He delivered the request, but was told by the bishop (Fray Juan Zumárraga) to come back another day after he had had time to reflect upon what Juan Diego had told him.
Upon the arrow being withdrawn, the victim made a full and immediate recovery.
but it was not until January 1984 that the then Archbishop of Mexico, Cardinal Ernesto Corripio Ahumada, named a Postulator to supervise and coordinate the inquiry, and initiated the formal process for canonization.
Third apparition: Juan Diego returned immediately to Tepeyac and, encountering the Virgin Mary reported the bishop's request for a sign; she condescended to provide one on the following day (December 11).
By Monday, December 11, however, Juan Diego's uncle Juan Bernardino had fallen sick and Juan Diego was obliged to attend to him.
There is no firm tradition as to their marital relations.
