The finding of Jesus in the temple is the only event that breaks the silence of the Gospels about the hidden years of Jesus.Here Jesus lets us catch a glimpse of the mystery of his total consecration to a mission that flows from his divine sonship: "Did you not know that I must be about my Father's work?"
Mary and Joseph did not understand these words, but they accepted them in faith.
Mary "kept all these things in her heart" during the years Jesus remained hidden in the silence of an ordinary life.
