When I first read the story of Our Lady of Guadalupe in Mexico, and learned about St Juan Diego, what most struck me about him was that once the spernatural nature of the image and message of Our Lady was recognsied, Juan Diego dedicated himself to that image and message, becoming as it were, the first guardian and catechist of the new Shrine of Our Lady on Tepeyac Hill. For the rest of his life he lived in a small room behind the new chapel - effectively, in the sacristy - and gave himself to welcoming visitors to the chapel and in speaking about Our Lady to them. He became a catechist of the Mystery of Christ, being an agent of that Mystery in the first shrine of Our Lady of Guadalupe.
Yesterday, on his feast day, I asked his prayers for those who will be chosen to be the new guardians of the Shrine of Our Lady of Walsingham. Since the Marist Fathers will be departing the shrine soon, it seems to me that the prayers of this humble servant of Our Lady of Guadalupe should be sought. England's Nazareth will soon need new guardians - to welcome pilgrims, to pray with them and to lead them deeper into the Mystery of Christ.
The pattern of St Juan Diego's life after Our Lady appeared to him, is a tremedous model for any shrine's guardians to seek to follow.
