I have already answered this previously. But for your sake, I shall answer again.
If Jesus was ONLY Divinity, then the crucifixion would not have been possible because it would be impossible to have Him killed.
There must therefore be a human portion of Jesus for Him to suffer the same pains as we do, which as what I have been telling you is that which was crucificied and is that which is not divinity.
What is physical therefore is not divine.
I have given this analogy many times. God is a Spirit. Think of it as a balloon with hydrogen in it. God is the hydrogen, Jesus is that Balloon that is filled with hydrogen. I am a balloon maker, not hydrogen maker…hydrogen came from the air/nature which I did not create.
.
Jesus = DIVINE PERSON = Fully GOD and fully human = what IS physical IS Divine.
After the fall, no human could make up for what happened, God tired to reconile through Noah who got drunk, Abraham who took a mistress, Moses who disobeyed…the ONLY way God could reconcile humankind to Himself was BY Himself.
Consider the following - reference at the end…
Every single action of Christ was the action of the Second Person of the Blessed Trinity, and this includes every action done by him in his human nature. For natures are sources of action-, but not doers. It is always the person who does them, and in his human nature there was but one single person, and that person was God. There was no human person, for that would have made him two people, each with his own distinct nature. His human nature was complete, but it was united to a divine person, not a human person.
We may make this clearer by glancing at two great Christian truths: Mary was the mother of God, and God died upon the cross.
Our Blessed Lady did exist before the Second Person of the Trinity was born into human nature; that this one Son already existed in his divine nature does not alter the truth that it was in her womb that he was conceived as man, from her womb born into our world. His eternal existence as Son of his heavenly Father does not by one jot diminish what she gave him. There is nothing received by any human being from his mother that he did not receive from her.
It was God the Son who died—not, of course, in his divine nature, which cannot know death and which holds the universe in existence, but in the human nature which was so utterly his. Death, remember, does not for any one of us mean annihilation. It means the separation of soul and body, a separation that at the last judgment will be ended. Upon Calvary, the body that was God the Son’s was separated from the soul that was likewise his. And on the third day they were united again. In his human nature God the Son rose from the death that in his human nature had been his.
In our reading of the Gospels, it is vital that we should never forget that every word uttered and every action performed by Christ is uttered and performed by God the Son. With the words, perhaps even more than with actions, we shall find sayings we are often tempted to call hard. The one Person said I, in the divine nature and in the human nature, in an infinite nature and a finite nature. He could say, “I and the Father are one”; he could say, “The Father is greater than I”; it is the same Person, uttering the truth of distinct natures, but asserting each nature as truly his own.
