A selected quote from the Catechism of the Catholic Church in honor of the Year of Faith (October 11, 2012 - November 24, 2013)
425 The transmission of the Christian faith consists primarily in proclaiming Jesus Christ in order to lead others to faith in him. From the beginning, the first disciples burned with the desire to proclaim Christ: "We cannot but speak of what we have seen and heard."' And they invite people of every era to enter into the joy of their communion with Christ:
That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon and touched with our hands, concerning the word of life - the life was made manifest, and we saw it, and testify to it, and proclaim to you the eternal life which was with the Father and was made manifest to us- that which we have seen and heard we proclaim also to you, so that you may have fellowship with us; and our fellowship is with the Father and with his Son Jesus Christ. And we are writing this that our joy may be complete.427 In catechesis "Christ, the Incarnate Word and Son of God,. . . is taught - everything else is taught with reference to him - and it is Christ alone who teaches - anyone else teaches to the extent that he is Christ's spokesman, enabling Christ to teach with his lips. . . Every catechist should be able to apply to himself the mysterious words of Jesus: 'My teaching is not mine, but his who sent me.'"
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.
436 The word "Christ" comes from the Greek translation of the Hebrew Messiah, which means "anointed". It became the name proper to Jesus only because he accomplished perfectly the divine mission that "Christ" signifies. In effect, in Israel those consecrated to God for a mission that he gave were anointed in his name. This was the case for kings, for priests and, in rare instances, for prophets. This had to be the case all the more so for the Messiah whom God would send to inaugurate his kingdom definitively. It was necessary that the Messiah be anointed by the Spirit of the Lord at once as king and priest, and also as prophet. Jesus fulfilled the messianic hope of Israel in his threefold office of priest, prophet and king.
441 In the Old Testament, "son of God" is a title given to the angels, the Chosen People, the children of Israel, and their kings. It signifies an adoptive sonship that establishes a relationship of particular intimacy between God and his creature. When the promised Messiah-King is called "son of God", it does not necessarily imply that he was more than human, according to the literal meaning of these texts. Those who called Jesus "son of God", as the Messiah of Israel, perhaps meant nothing more than this.
446 In the Greek translation of the Old Testament, the ineffable Hebrew name YHWH, by which God revealed himself to Moses, is rendered as Kyrios, "Lord". From then on, "Lord" becomes the more usual name by which to indicate the divinity of Israel's God. The New Testament uses this full sense of the title "Lord" both for the Father and - what is new - for Jesus, who is thereby recognized as God Himself.
447 Jesus ascribes this title to himself in a veiled way when he disputes with the Pharisees about the meaning of Psalm 110, but also in an explicit way when he addresses his apostles. Throughout his public life, he demonstrated his divine sovereignty by works of power over nature, illnesses, demons, death and sin.
