I believe in the hypostatic union of Christ

I believe in the hypostatic union of Christ because the Bible teaches that Jesus Christ is one person with two complete and distinct natures: He is fully God and fully man. The eternal Son of God did not become less than God when He took on human flesh, nor did His humanity merely appear to be real. Rather, in the incarnation, the second person of the Trinity assumed a true human nature while remaining fully divine. John 1:1 declares that “the Word was God,” and John 1:14 teaches that “the Word became flesh and dwelt among us.” These verses show that Jesus did not begin to exist at Bethlehem, but that the eternal Son entered into human history by taking on a real human body and soul. He remained what He always was—fully God—while becoming what He had not been before—fully man.

This doctrine is essential to the Christian faith because the gospel depends on Christ being both truly divine and truly human. If Jesus were not fully God, He could not reveal God perfectly, bear the full weight of divine judgment, conquer sin and death, or save sinners completely. Colossians 2:9 says that “in him the whole fullness of deity dwells bodily,” meaning that Jesus is not merely a messenger from God but God Himself in human flesh. At the same time, if Jesus were not fully man, He could not stand in our place as our representative. Hebrews 2:14 teaches that since we share in flesh and blood, Christ likewise partook of the same nature. He was born, grew, hungered, thirsted, suffered, wept, obeyed, bled, and died. His humanity was not an illusion. He became like us in every way, yet without sin, so that He could obey where Adam failed and offer Himself as the perfect sacrifice for His people.

The hypostatic union also protects the church from false views of Christ. Some have denied His deity and treated Him as a created being or merely a great teacher. Others have denied His humanity and viewed His body as only an appearance. Still others have confused His two natures or divided Him into two persons. Biblical Christianity rejects all of these errors. Jesus Christ is one person in two natures, without confusion, change, division, or separation. His divine nature remains fully divine, and His human nature remains fully human, yet both are forever united in the one person of the Son. This means the child born in Bethlehem was truly Immanuel, God with us. The One who grew tired was the Lord of creation. The One who wept at Lazarus’s tomb was the Resurrection and the Life. The One who died on the cross was the Lord of glory, suffering according to His human nature while remaining the eternal and sovereign Son of God.

Therefore, I believe in the hypostatic union because without it there is no biblical Christ, no true incarnation, no sufficient atonement, and no saving gospel. Jesus must be fully God in order to save, and He must be fully man in order to represent us. As 1 Timothy 2:5 says, “there is one mediator between God and men, the man Christ Jesus.” He alone is able to mediate between God and sinners because He shares fully in the divine nature and fully in our human nature, yet without sin. This doctrine should lead believers not merely to intellectual agreement, but to worship. The eternal Son humbled Himself, took the form of a servant, obeyed unto death, and rose again in victory. The hypostatic union reveals the glory, humility, mercy, and majesty of Christ. He is the Son of God and the Son of Man, one person with two natures, forever worthy of our faith, obedience, and worship.
