Mary stored up all these things in her heart
Every year the parents of Jesus used to go to Jerusalem for the feast of the Passover. When he was twelve years old, they went up for the feast as usual. When they were on their way home after the feast, the boy Jesus stayed behind in Jerusalem without his parents knowing it. They assumed he was with the caravan, and it was only after a day’s journey that they went to look for him among their relations and acquaintances. When they failed to find him they went back to Jerusalem looking for him everywhere.
Three days later, they found him in the Temple, sitting among the doctors, listening to them, and asking them questions; and all those who heard him were astounded at his intelligence and his replies. They were overcome when they saw him, and his mother said to him, ‘My child, why have, you done this to us? See how worried your father and I have been, looking for you.’
‘Why were you looking for me?’ he replied. ‘Did you not know that I must be busy with my Father’s affairs?’ But they did not understand what he meant.
He then went down with them and came to Nazareth and lived under their authority. His mother stored up all these things in her heart.

The mysteries of Jesus’ hidden life
531 During the greater part of his life Jesus shared the condition of the vast majority of human beings: a daily life spent without evident greatness, a life of manual labor. His religious life was that of a Jew obedient to the law of God, a life in the community. From this whole period it is revealed to us that Jesus was “obedient” to his parents and that he “increased in wisdom and in stature, and in favor with God and man.”
532 Jesus’ obedience to his mother and legal father fulfills the fourth commandment perfectly and was the temporal image of his filial obedience to his Father in heaven. The everyday obedience of Jesus to Joseph and Mary both announced and anticipated the obedience of Holy Thursday: “Not my will. . .” The obedience of Christ in the daily routine of his hidden life was already inaugurating his work of restoring what the disobedience of Adam had destroyed.
533 The hidden life at Nazareth allows everyone to enter into fellowship with Jesus by the most ordinary events of daily life:
The home of Nazareth is the school where we begin to understand the life of Jesus – the school of the Gospel. First, then, a lesson of silence. May esteem for silence, that admirable and indispensable condition of mind, revive in us. . . A lesson on family life. May Nazareth teach us what family life is, its communion of love, its austere and simple beauty, and its sacred and inviolable character. . . A lesson of work. Nazareth, home of the “Carpenter’s Son”, in you I would choose to understand and proclaim the severe and redeeming law of human work. . . To conclude, I want to greet all the workers of the world, holding up to them their great pattern their brother who is God.
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.
For the leader; of David. For remembrance.
Graciously rescue me, God! Come quickly to help me, LORD!
Confound and put to shame those who seek my life. Turn back in disgrace those who desire my ruin.
Let those who say “Aha!” turn back in their shame.
But may all who seek you rejoice and be glad in you. May those who long for your help always say, “God be glorified!”
Here I am, afflicted and poor. God, come quickly! You are my help and deliverer. LORD, do not delay!
