Deus exaltavit illum, et donavit illi nomen, quod est super omne nomen
What is the meaning of the name “Jesus”?
Given by the angel at the time of the Annunciation, the name “Jesus” means “God saves”. The name expresses his identity and his mission “because he will save his people from their sins” (Matthew 1:21). Peter proclaimed that “there is no other name under heaven given to men by which we can be saved” (Acts 4:12). 
Why is Jesus called “Christ”?
“Christ” in Greek, “Messiah” in Hebrew, means the “anointed one”. Jesus is the Christ because he is consecrated by God and anointed by the Holy Spirit for his redeeming mission. He is the Messiah awaited by Israel, sent into the world by the Father. Jesus accepted the title of Messiah but he made the meaning of the term clear:“come down from heaven” (John 3:13), crucified and then risen, he is the Suffering Servant “who gives his life as aransom for the many” (Matthew 20:28). From the name Christ comes our name of Christian.
In what sense is Jesus the Only Begotten Son of God?
Jesus is the Son of God in a unique and perfect way. At the time of his Baptism and his Transfiguration, the voice of the Father designated Jesus as his “beloved Son”. In presenting himself as the Son who “knows the Father” (Matthew 11:27), Jesus affirmed his singular and eternal relationship with God his Father. He is “the Only Begotten Son of God” (1 John 4:9), the second Person of the Blessed Trinity. He is the central figure of apostolic preaching. The apostles saw “his glory as of the Only Begotten of the Father” (John 1:14).
What is the meaning of the title “Lord”?
In the Bible this title regularly designates God as Sovereign. Jesus ascribed this title to himself and revealed his divine sovereignty by his power over nature, over demons, over sin, and over death, above all by his own Resurrection. The first Christian creeds proclaimed that the power, the honor, and the glory that are due to God the Father also belong to Jesus: God “has given him the name which is above every other name” (Philippians 2:9). He is the Lord of the world and of history, the only One to whom we must completely submit our personal freedom.
