Am I not here, who is your Mother?

"Hear me and understand well, my son the least, that nothing should frighten or grieve you. Let not your heart be disturbed. Do not fear that sickness, nor any other sickness or anguish. Am I not here, who is your Mother? Are you not under my protection? Am I not your health? Are you not happily within my fold? What else do you wish? Do not grieve nor be disturbed by anything. Do not be afflicted by the illness of your uncle, who will not die now of it. be assured that he is now cured."

The Blessed Virgin Mary's words to St. Juan Diego as recounted in the Nican Mopohua, the first historical documentation of Our Lady of Guadalupe. The Nican Mopohua was written in the language of the Aztecs, Nahuatl, by one of the first Aztec converts educated in Bishop Zumarraga's schools, Don Antonio Valeriano, in 1540. An illustration of the apparition event with the signature of Don Antonio Valeriano and the date 1548 was recently uncovered in a private collection in 1995, now referred to as the Codex 1548. The Codex 1548 has been scientifically studied and determined to be genuine, and substantiates the historical basis of the apparition of Guadalupe.
