Read the Catechism: Day 78
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.
536 The baptism of Jesus is on his part the acceptance and inauguration of his mission as God's suffering Servant. He allows himself to be numbered among sinners; he is already "the Lamb of God, who takes away the sin of the world". Already he is anticipating the "baptism" of his bloody death. Already he is coming to "fulfill all righteousness", that is, he is submitting himself entirely to his Father's will: out of love he consents to this baptism of death for the remission of our sins. The Father's voice responds to the Son's acceptance, proclaiming his entire delight in his Son. The Spirit whom Jesus possessed in fullness from his conception comes to "rest on him". Jesus will be the source of the Spirit for all mankind. At his baptism "the heavens were opened" — the heavens that Adam's sin had closed — and the waters were sanctified by the descent of Jesus and the Spirit, a prelude to the new creation.
537 Through Baptism the Christian is sacramentally assimilated to Jesus, who in his own baptism anticipates his death and resurrection. The Christian must enter into this mystery of humble self-abasement and repentance, go down into the water with Jesus in order to rise with him, be reborn of water and the Spirit so as to become the Father's beloved son in the Son and "walk in newness of life":
Let us be buried with Christ by Baptism to rise with him; let us go down with him to be raised with him; and let us rise with him to be glorified with him.
Everything that happened to Christ lets us know that, after the bath of water, the Holy Spirit swoops down upon us from high heaven and that, adopted by the Father's voice, we become sons of God.
