This topic is about Jesus Christ. Let’s use the Question and Answer format for clarity and conciseness.
The hypostatic union says two natures (deity and humanity) are united in one person—the person of Jesus Christ. Two natures united in one person is called the hypostatic union, or one-person union.
Don’t feel frustrated if you don’t get this at first and you have to read it several times. Sooner or later, things will “click.” It’s a profound mystery, after all!

1.. What is a more formal definition of the hypostatic union?
Here is one from the Evangelical Dictionary of Theology:
… The union of two natures (duo physeis) of deity and humanity in the one hypostasis or person of Jesus Christ. In the incarnation of the Son of God, a human nature was inseparably united forever with the divine nature, yet with the two natures remaining distinct, whole, and unchanged, without mixture or confusion, so that the one person, Jesus Christ, is truly God and truly human (p. 410).
That definition is based on the Creed of Chalcedon in 451 AD. The three major branches of the church, with almost all of their subdivisions or denominations, believe it: Protestant, Catholic, and Eastern Orthodox.

4.. If Jesus is fully human, did he have a sin nature?
No, because man with a sin nature is not fully human; he is less than that. Man is degraded in his essence, because it is tainted by sin.
5.. Is there an illustration to clarify it?
Yes, two imperfect ones.
The first illustrates how one person can have the physical and nonphysical and yet remain one person. We humans are soul and matter.
My body moves and types these words—my fingers and hands (material) type them, but the mind (immaterial) is also involved. I don’t say that my fingers or toes had nothing to do with it, or my mind typed it. Instead we simply affirm that I did that. Matter and soul did this together, but they are distinct. Yet one person—body and soul—did it.
As Renewal theologian J. Rodman William insightfully says, “One possible help in understanding this paradox [of two natures in one person] is to reflect on the operation of God’s grace in a Christian’s life” (vol. 1, p. 344). 2 Pet. 1:4 says that we “partake of the divine nature.” So now the born-again believer has two natures—human and (partly) divine.
Of course the illustration is imperfect (Millard Erickson notes its limitations, p. 669), because our human nature is tainted with sin, and we received a divine nature at one point in time. Jesus, on the other hand, never received his fully divine nature, for he always had in eternity past. And his human nature was not tainted with sin. But it illustrates two natures living in one person—you.
6.. Are the two natures united in one person forever?
Yes, right now Christ has those two natures, and even in a body, but on his resurrection it has been transformed into an immortal, incorruptible body that lives forever. One can see the nail wounds or scars in his hands and feet, but his body will never decompose, but will go on forever—ours too, after we die.
7.. Isn’t all this just made up by the later church and unintelligible?
Jesus Christ is the one and only, unique person whoever walked the globe, for he was the theanthropos—the God-man. It is a profound mystery, and a mystery is not irrational.
It is not unintelligible; maybe we’re just unintelligent—not intelligent enough. As noted at Question 5, we have the divine nature living in us, so the whole thing may not be clear in its details, but it is not beyond our experience.
And as noted, Scripture everywhere affirms his full humanity and his full divinity. We ignore those verses to our doctrinal peril. At the Chalcedonian Council, the creed which the councilors produced summarized all those verses into one succinct document. There is nothing wrong with writing up a creed.
6.. Is there an image that can clarify the hypostatic union?
Wayne Grudem has this one (p. 558).
It shows God (Father, Son, and Holy Spirit) in the one big circle. The person of Christ (dotted circle) has two natures: Human (stick figure), which is outside the “God Circle,” and the divine, which is inside the “God Circle.” Two natures (human and divine) in one person, Jesus the Son.
With the human nature outside of the “God Circle” it is easy to understand why the people of Jesus’ time, who saw him in person, and modern scholars see only his human nature and miss his divine nature—the human nature is most visible to them.
7.. Can you show how the two natures worked in the one person of Jesus the Messiah?
In his human nature he ascended into heaven (John 16:28 and Acts 1:9-11), but in his divine nature he was everywhere present (Matt. 18:20 and 28:20; John 14:23). Both things are true about the person of Christ. So it is correct to say “Jesus returned to heaven, and Jesus is here with us right now.” The first is true of his human nature, and the second is true of his divine nature—two natures contained in his one person named Jesus.
Jesus was about thirty years old when he began his ministry (Luke 3:23) in his human nature, but he eternally existed in his divine nature (John 1:1-2; 8:58). Both are true about the person of Jesus. So it is correct to say, “Jesus began his ministry at about thirty, and Jesus existed from eternity past.” The first is true of his human nature, the second is true of his divine nature—two natures contained in his one person called Jesus.
When Jesus was a baby in the cradle, did he hold the universe together (Col. 1:17) and sustain it by the word of his power (Heb. 1:3)? His human nature could not do that, but his divine nature could and did. Each nature did what was unique to itself. So it is correct to say, “In his (baby) human nature he did not do that, but in his divine nature he did.” Either way, it is correct to say that Jesus always held up the universe.
The reader already understands where this is going in respect to God “dying” at Jesus’s crucifixion.
In his human nature he died, but in his divine nature he did not die. So, no, God did not die. But it is correct to say that Jesus died in his human nature and natural body, but Jesus was always alive in his divine nature and his new, transformed, incorruptible body.
8.. Was his divine nature hidden during his earthly ministry?
Mostly yes, because Jesus had two wills, divine and human. He surrendered both to his Father in heaven, who told him to live like a man in every way possible, yet without sin. However, by his Father’s permission, sometimes his divine nature burst forth in miracles like calming the storm, walking on water, at his baptism when the Father, Son and Holy Spirit appeared or made their presence known (Matt. 3:16-17), or at the Mount of Transfiguration, when he shone in glory (Matt. 17:1-5).
9.. Why did the Father tell him to live like a man (without sin)?
Heb. 4:15 answers it: “For we do not have a high priest unable to empathize with our weaknesses, but we have one who has been tempted in every way, just as we are—yet without sin.”
In other words, the Father sent his Son to redeem the world and show us the Father empathizes with human suffering. That’s how much he loves us.
So how can I get to know Jesus more deeply?
You now have clarity. He is two natures (divine and human) in one person.
Wayne Grudem summarizes this wonderful doctrine of the hypostatic union:
At the end of this long discussion, it may be easy for us to lose sight of what is actually taught in Scripture. It is by far the most astounding miracle of the entire Bible—far more amazing than the resurrection and more amazing than the creation of the universe. The fact that the infinite, omnipotent, eternal Son of God could become man and join himself to a human nature forever, so that infinite God became one person with finite man, will remain for eternity the most profound miracle and the most mystery in all the universe. (p. 563)
In Jesus Christ’s full humanity, God the Father can relate to us. In Jesus Christ’s full deity, the Father can redeem us from our sins.
This doctrine goes right to our salvation and our eternal life and our relation with the Father, the Son, and the Holy Spirit.
