The Old Testament foretold that the promised Redeemer would be God (Is7, 14). Isaiah said, “The Lord Himself will give you this sign: the Virgin shall be with child and bear a Son, and you shall name Him Immanuel” (This word means “God is with us”) .
In the New Testament Simon Peter confesses Jesus as the “Messiah, the Son of the living God”. Jesus said to Him in reply, “Flesh and blood has not revealed this to you but my Father who is in heaven" (Matthew 16: 16-17).
Jesus Christ is Man.
Jesus Christ is man because He is the son of the Virgin Mary and He has a body and a soul like ours. Although Christ’s conception and birth were miraculous, He, like other men, came into the world as an infant, having Mary for His Mother. Since His origin from the Blessed Virgin is true generation, Mary is the Mother of Jesus Christ, who is God, and she is therefore truly the Mother of God. Christ, like other men, ate, drank, slept and walked. Christ as man was the most perfect of all men. He had human intelligence and free will; but He was free from ignorance and error, from sin and imperfection. The human soul of Christ could suffer as well as His body. For example, Christ was sorrowful. In the garden of Gethsemane He said to His disciples: “My soul is sad, even unto death. Wait here and watch with me” (Matt. 26:38).
Christ Declared Himself to be God
He said, “The Father and I are one” (John 10:30). In Saint Matthew’s Gospel we read, “Then the high priest said to Him, ‘I order you to tell us under oath before the living God whether You are the Messiah.' Jesus said to him in reply ‘you have said so. But I tell you: from now on you will see the Son of Man seated at the right hand of the Power and coming on the clouds of heaven’. The High Priest tore his robes and said, ‘‘He has blasphemed’” (Matt. 26: 63-64). The blasphemy was that Jesus declared himself to be God.
Christ has Two Natures
Jesus Christ has the nature of God and the nature of man. There is a difference between person and nature. Person answers the question “who” and Nature answers the question “what”. Human nature is composed of body and soul. Each human person has its own human nature. Christ is a divine Person who has the divine nature and has taken a human nature.
Was the Son of God always Man?
The Son of God was not always man. He became man by His Incarnation in the womb of the Blessed Virgin Mary. At that time the Son of God, retaining His divine nature, took to himself a human nature, that is, a body and a soul like ours. The union of the second Person of the Blessed Trinity with human nature is called the hypostatic union. Hypostatic union is the union of two natures in the one person. Again, Jesus is one person, the second person of the Blessed Trinity and he has two natures, he is really God, with a divine nature and he is truly man with a human nature. The hypostatic union means that the two natures are united in the one person-Jesus.
Jesus' Mission to the World
Jesus' whole mission, his entire life, his sufferings, death, and resurrection are built on the knowledge that we are called to live in happiness with God for eternity. The Lord Jesus Christ lived and died to purchase for us the right to call ourselves adopted children of God, with new life
