The Hypostatic Union is a doctrinal phrase used in theology that refers to the uncompromised and undiluted unity between Jesus’ divine and human nature. It answers the question, “Was Jesus 100 percent man, or 100 percent God?” The answer is He was both. Christ in all his humanity never ceased being 100 percent God, and Christ in all his divinity never ceased being 100 percent man. This relationship between the two natures in a single subsistence is what we refer to as the Hypostatic Union.
While there is no one scripture we can point to that singularly describes both natures in one body, God still reveals his true nature to us when we compare compare scriptures that show both natures.
Scriptures that show Christ Deity:
He was Eternal: “He is before all things, and in him all things hold together. (Colossians 1:17)”
He was Omnipotent: “who, by the power that enables him to bring everything under his control, will transform our lowly bodies so that they will be like his glorious body. (Philippians 3:21)”
He was Omnipresent: “Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age. (Matthew 28:18-20)”
He was Omniscient: “Now we can see that you know all things and that you do not even need to have anyone ask you questions. This makes us believe that you came from God. (John 16:30)”
He was called God: “Now all this is come to pass, that it might be fulfilled which was spoken by the Lord through the prophet, saying, Behold, the virgin shall be with child, and shall bring forth a son, and they shall call his name Immanuel; which is, being interpreted, God with us. (Matthew 1:22-23)”; “Theirs are the patriarchs, and from them is traced the human ancestry of the Messiah, who is God over all, forever praised! Amen. (Romans 9:5)”
He was credited with Creation: “Through him all things were made; without him nothing was made that has been made. (John 1:3)”
He had authority over death: “When he had said this, Jesus called in a loud voice, ‘Lazarus, come out!’ The dead man came out, his hands and feet wrapped with strips of linen, and a cloth around his face. Jesus said to them, ‘Take off the grave clothes and let him go.’ (John 11:43-44)”
Scriptures that show Christ Humanity:
He was born: “And she gave birth to her firstborn son and wrapped him in swaddling cloths and laid him in a manger, because there was no place for them in the inn. (Luke 2:7)”
He grew: “And the child grew and became strong, filled with wisdom. And the favor of God was upon him. (Luke 2:40)”
He became tired: “Jacob’s well was there, so Jesus, wearied as he was from his journey, was sitting beside the well. It was about the sixth hour. (John 4:6)”
He felt thirst and hunger: “After this, Jesus, knowing that all was now finished, said (to fulfill the scripture), ‘I thirst.’ (John 19:28)”; “And after fasting forty days and forty nights he was hungry. (Matthew 4:2)”
He had human flesh: “See my hands and my feet, that it is I myself. Touch me, and see. For a spirit does not have flesh and bones as you see that I have. (Luke 24:39)”
He felt sorrow: “Now is my soul troubled. And what shall I say? ‘Father, save me from this hour’? But for this purpose, I have come to this hour. (John 12:27)”
He cried and felt fear: “In the days of his flesh, Jesus offered up prayers and supplications, with loud cries and tears, to him who was able to save him from death, and he was heard because of his reverence. (Hebrews 5:7)”
He had his own will: “I have come down from heaven, not to do my own will but to do the will of him who sent me. (John 6:38)”
Christ was in all ways human: “Therefore, he had to be made like his brothers in every respect, so that he might become a merciful and faithful high priest in the service of God, to make propitiation for the sins of the people. (Hebrews 2:17)”
Scriptures that indicate both natures:
Other scripture verses that evidence the hypostatic union are: “And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth. (John 1:1)”; “For in him the whole fullness of deity dwells bodily (Colossians 2:9)”; “For there is one God, and there is one mediator between God and men, the man Christ Jesus (1 Timothy 2:5)”; “Since therefore the children share in flesh and blood, he himself likewise partook of the same things, that through death he might destroy the one who has the power of death, that is, the devil, (Hebrews 2:14).”
Therefore, if Jesus is undoubtedly God and man then he is uniquely the God-man – both deity and humanity in one body – and that is what is meant by the Hypostatic Union.
