Who Is Jesus Christ?
Last updated: 2026-04-13
Jesus Christ is the eternal Son of God, who became true man in order to be the one mediator between God and man. He is our only Redeemer, having saved His people from their sins through His life, death, and resurrection.
👑 The Person of Christ
Jesus Christ is uniquely both God and man. According to the Small Catechism Q.7, He is the Son of God, true God and man. This mystery of the incarnation—where the eternal Son assumed a human nature—is essential to our salvation. The Westminster Shorter Catechism Q.21 describes Him as the only Redeemer of God's elect, who continues to be God and man in two distinct natures and one person forever. As noted in Hebrews 1:1-3, He is the brightness of God's glory and the express image of His person, having purged our sins by Himself before sitting down at the right hand of the Majesty on high.

❤️ Our Only Mediator and Savior
The name 'Jesus' signifies 'Saviour,' for as the Westminster Larger Catechism Q.41 teaches, He is called Jesus because He saves His people from their sins. The Heidelberg Catechism Q.29 adds that we ought not to seek, nor can we find, salvation in any other. Because we are, by nature, dead in trespasses and unable to keep God's law, we rest entirely upon the finished work of Christ. As the Apostle Peter declares in Acts 4:12, there is none other name under heaven that is given among men, wherein we must be saved. You are more sinful than you ever dared believe, yet more loved in Christ than you ever dared hope.

The Bible teaches that Jesus Christ is the eternal Son of God, true God and true man, who serves as the sole Mediator and Redeemer. His mission was to reconcile humanity to the Father through his incarnation, substitutionary death, and glorious resurrection.
📖 The Eternal Son of God
The Scriptures affirm that Jesus Christ is the eternal Son of God, coequal and consubstantial with the Father. He is not a created being, but the Word who was with God and was God from the beginning (Second Helvetic Confession Ch. XI). As the Westminster Confession Ch. 8 §2 states, he is the second person in the Trinity, being very and eternal God. This identity is essential to our gospel hope, for if he were not true God, he could not bear the infinite weight of divine wrath on behalf of sinners.

🤝 True Man and True God
In the fullness of time, the Son of God took upon himself true human nature, being conceived by the Holy Spirit and born of the virgin Mary. This union of two distinct natures—the divine and the human—in one person is the 'hypostatic union.' As the Chalcedonian Definition teaches, he is one and the same Son, truly God and truly man, with the properties of both natures preserved without confusion or change. The Scripture captures this mystery in John 1:14: 'And the Word became flesh, and dwelt among us (and we beheld his glory, glory as of the only begotten from the Father), full of grace and truth.'

✝️ The Sole Mediator and Savior
Christ’s mission was to be the one mediator between God and man. He fulfilled this by living a life of perfect obedience, suffering death for our sins, and rising again to restore life and immortality. We are reminded by Peter: 'And in none other is there salvation: for neither is there any other name under heaven, that is given among men, wherein we must be saved' (Acts 4:12). Because we are more sinful than we dare believe, we need a Mediator who is both God and man; because we are more loved than we dare hope, he has accomplished this salvation entirely through his own finished work, calling us to rest in him alone (1689 LBCF Ch. 8).
