+ Lk 2: 41-51a
Each year his parents went to Jerusalem for the feast of Passover,
and when he was twelve years old, they went up according to festival custom.
After they had completed its days, as they were returning, the boy Jesus remained behind in Jerusalem, but his parents did not know it.
Thinking that he was in the caravan, they journeyed for a day and looked for him among their relatives and acquaintances,
but not finding him, they returned to Jerusalem to look for him.
After three days they found him in the temple, sitting in the midst of the teachers, listening to them and asking them questions,
and all who heard him were astounded at his understanding and his answers.
When his parents saw him, they were astonished, and his mother said to him, “Son, why have you done this to us? Your father and I have been looking for you with great anxiety.”
And he said to them, “Why were you looking for me? Did you not know that I must be in my Father’s house?”
But they did not understand what he said to them.
He went down with them and came to Nazareth, and was obedient to them; and his mother kept all these things in her heart.
The New American Bible
The Catechism of the Catholic Church
534 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.
Joseph (Hebrew: יוֹסֵף, translit. Yosef; Greek: Ἰωσήφ, translit. Ioséph) is a figure in the Gospels, the husband of Mary, mother of Jesus, and is venerated as Saint Joseph in the Catholic Church, Orthodox Church, Oriental Orthodox Church, Anglican Communion, Lutheranism and Methodism. Christian tradition places Joseph as Jesus’ foster father. Some historians state that Joseph was Jesus’s father. Some differing views are due to theological interpretations versus historical views.
In both Catholic and Protestant traditions, Joseph is regarded as the patron saint of workers and is associated with various feast days. Pope Pius XI declared him to be both the patron and the protector of the Catholic Church, in addition to his patronages of the sick and of a happy death, due to the belief that he died in the presence of Jesus and Mary. In popular piety, Joseph is regarded as a model for fathers and has also become patron of various dioceses and places.
