+ Jn 1: 29-34
The next day he saw Jesus coming toward him and said, “Behold, the Lamb of God, who takes away the sin of the world.
He is the one of whom I said, ‘A man is coming after me who ranks ahead of me because he existed before me.’
I did not know him, but the reason why I came baptizing with water was that he might be made known to Israel.”
John testified further, saying, “I saw the Spirit come down like a dove from the sky and remain upon him.
I did not know him, but the one who sent me to baptize with water told me, ‘On whomever you see the Spirit come down and remain, he is the one who will baptize with the holy Spirit.’
Now I have seen and testified that he is the Son of God.”
The New American Bible
Catechism of the Catholic Church
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.
The Most Holy Name of Jesus
The Catechism of the Catholic Church
430 Jesus means in Hebrew: “God saves.” At the annunciation, the angel Gabriel gave him the name Jesus as his proper name, which expresses both his identity and his mission. Since God alone can forgive sins, it is God who, in Jesus his eternal Son made man, “will save his people from their sins”. in Jesus, God recapitulates all of his history of salvation on behalf of men.
431 In the history of salvation God was not content to deliver Israel “out of the house of bondage” by bringing them out of Egypt. He also saves them from their sin. Because sin is always an offence against God, only he can forgive it. For this reason Israel, becoming more and more aware of the universality of sin, will no longer be able to seek salvation except by invoking the name of the Redeemer God.
432 The name “Jesus” signifies that the very name of God is present in the person of his Son, made man for the universal and definitive redemption from sins. It is the divine name that alone brings salvation, and henceforth all can invoke his name, for Jesus united himself to all men through his Incarnation, so that “there is no other name under heaven given among men by which we must be saved.”
433 The name of the Savior God was invoked only once in the year by the high priest in atonement for the sins of Israel, after he had sprinkled the mercy seat in the Holy of Holies with the sacrificial blood. The mercy seat was the place of God’s presence. When St. Paul speaks of Jesus whom “God put forward as an expiation by his blood”, he means that in Christ’s humanity “God was in Christ reconciling the world to himself.”
434 Jesus’ Resurrection glorifies the name of the Savior God, for from that time on it is the name of Jesus that fully manifests the supreme power of the “name which is above every name”. The evil spirits fear his name; in his name his disciples perform miracles, for the Father grants all they ask in this name.
435 The name of Jesus is at the heart of Christian prayer. All liturgical prayers conclude with the words “through our Lord Jesus Christ”. The Hail Mary reaches its high point in the words “blessed is the fruit of thy womb, Jesus.” The Eastern prayer of the heart, the Jesus Prayer, says: “Lord Jesus Christ, Son of God, have mercy on me, a sinner.” Many Christians, such as St. Joan of Arc, have died with the one word “Jesus” on their lips.
