> A normal person according to Christianity is closer to having two natures in the way you describe, because their body is mortal while their soul isn't.

AH, THERE'S YOUR PROBLEM! Cartesian dualism isn't the best lens to view human nature through and it makes talking about Christ's nature harder than it needs to be. The human person is a being whose nature is body+soul. The separation of the soul and the body at death is an evil brought about by sin. Put another way, death is injurious to human beings, not natural to them. (See https://www.newadvent.org/summa/3164.htm#article1).

Jesus is fully man. His human nature is body+soul. His human soul is immortal, as all human souls are. Unlike other human beings (other than Adam and Eve before they sinned) He was not subject to death as a punishment for sin, but He accepted it on our behalf. When He died, he really died. His soul and His body were separated and for three days He could be spoken of as "not a man". See https://www.newadvent.org/summa/4050.htm#article4 for the details. Follow that up with https://www.newadvent.org/summa/1075.htm#article4 for how that relates to us. One particularly striking quote - "[c]onsequently, to say that Christ was a man during the three days of His death simply and without qualification, is erroneous. Yet it can be said that He was "a dead man" during those three days."

Jesus is also fully God. His divine nature is perfect and unchanging. His divine nature is immutable (not merely immortal) and was not subject to death. Thus Jesus was subject to death in His human nature not in His divine nature.

I'm not going to respond to any arguments that rest on the veracity of mythology (such as the garden of Eden). I'm only interested in the internal consistency of Christian doctrine.

>Jesus is also fully God. His divine nature is perfect and unchanging. His divine nature is immutable (not merely immortal) and was not subject to death. Thus Jesus was subject to death in His human nature not in His divine nature.

This is maddening. Okay, so these are the logical relationships between the terms,

* Jesus is fully God.

* God is immutable.

* Something immutable is also immortal (and by contraposition, something mortal is not immutable).

* Jesus is fully man.

* Jesus is mortal and died.

Correct? None of this is in dispute, I assume, since it's what you said. Alright. To this I answer: if Jesus is mortal then he is not immutable, and if he's not immutable then he's not fully God. If you insist he is God then that's a contradiction by the terms you yourself laid out. The supposed two natures don't matter if they lead to this conclusion.

To give a simple analogy, you can make a sword that's sharp only halfway along its length and is blunt the rest of the way. The statements "the sword is sharp" and "the sword is blunt" are both simultaneously true. What you can't do is make a sword that's both sharp and blunt all throughout its length. You can say, "well, God can do the logically impossible". Fine. But then you're telling me that I'm right, that Christian theology does contain contradictions.

[svieira]

Yep - you're still missing the distinction. Jesus is the person. This person has two natures (we've been working with the "being a judge and a doctor" analogy here and both can be operative together, as when the judge is hearing a case where his knowledge of medicine has bearing on his ability to judge the situation). One nature is immutable, the other is mutable. Nothing contradicts there. "Jesus, in His human nature, changes. God the Son (His divine nature) does not change." But you can make it sound contradictory, just as you could say (if we make "The doctor does not judge, but the judge does" sound contradictory if we say "Susan does not judge but Susan judges!") It is not a logical contradiction for two distinct things to be distinct.

[fluoridation]

Like I've said more than enough times already, Susan is not wholly a judge nor wholly a doctor. If every part of her was simultaneously judge and doctor in equal parts and completely, then it would be false to say "Susan does not judge in a medical capacity, she judges in a judicial capacity", because she would not be able to compartmentalize those two aspects of her self. Everything she does would be in both capacities, because she is wholly those things.

You are both a eukaryote and three-dimensional. Everything you do is in the capacity of a three-dimensional eukaryote and there's no way for you to momentarily abandon one of those natures while you do something. Not without fundamentally changing what you are.

Jesus' must be equally and inextricably imbued by these natures if he is to be said "wholly" human and divine. More so, in fact, because at least your atoms are not eukaryotic. So if Jesus changes, God the Son also changes, because Jesus is God the Son. They're two names for the same thing. If they're not the same thing, if Jesus does not completely overlap with God the Son, then Jesus is not wholly divine. There are parts of him that are not divine. That's a tenable position, but it's not the position of the church.

[svieira]

Actually, that _is_ the position of the Church, funnily enough. Jesus is both God and man. These natures are distinct in Him, while being entire and wholly what they are (the God-nature is not diminished or changed by admixture and human-nature is not absorbed by the totality of divinity). One person, two natures.

[fluoridation]

No, that's very much not the position of the church. There are no parts of Jesus that are not divine, nor parts of Jesus that are not human. That's what "wholly" means, and that's where the contradiction stems from. Without necessarily falling into a contradiction, Jesus could be partly divine and partly human, or wholly divine and wholly non-human, or wholly human and wholly non-divine. It's him being both things wholly that is nonsense.

[svieira]

Without distinction, which you're ignoring, you are correct. But "wholly" means several things depending on what you're referring to. You could mean:

1. Everything that is (in the "esse" sense) of Jesus must be both. This seems to be your position. This is also an immediate contradiction since then either God changed or Jesus' humanity always was. Variations of this position (since it has several) have been defined heresy for literally 1,500 years. 2. Jesus is both God and man completely (not "the appearance of man" or "a man apart from God, divinized by God at a later point"). This is the position of the Church.

> 464 The unique and altogether singular event of the Incarnation of the Son of God does not mean that Jesus Christ is part God and part man, nor does it imply that he is the result of a confused mixture of the divine and the human. He became truly man while remaining truly God. Jesus Christ is true God and true man. During the first centuries, the Church had to defend and clarify this truth of faith against the heresies that falsified it.

> 465 The first heresies denied not so much Christ's divinity as his true humanity (Gnostic Docetism). From apostolic times the Christian faith has insisted on the true incarnation of God's Son "come in the flesh".87 But already in the third century, the Church in a council at Antioch had to affirm against Paul of Samosata that Jesus Christ is Son of God by nature and not by adoption. the first ecumenical council of Nicaea in 325 confessed in its Creed that the Son of God is "begotten, not made, of the same substance (homoousios) as the Father", and condemned Arius, who had affirmed that the Son of God "came to be from things that were not" and that he was "from another substance" than that of the Father.88

> 466 The Nestorian heresy regarded Christ as a human person joined to the divine person of God's Son. Opposing this heresy, St. Cyril of Alexandria and the third ecumenical council, at Ephesus in 431, confessed "that the Word, uniting to himself in his person the flesh animated by a rational soul, became man."89 Christ's humanity has no other subject than the divine person of the Son of God, who assumed it and made it his own, from his conception. For this reason the Council of Ephesus proclaimed in 431 that Mary truly became the Mother of God by the human conception of the Son of God in her womb: "Mother of God, not that the nature of the Word or his divinity received the beginning of its existence from the holy Virgin, but that, since the holy body, animated by a rational soul, which the Word of God united to himself according to the hypostasis, was born from her, the Word is said to be born according to the flesh."90

> 467 The Monophysites affirmed that the human nature had ceased to exist as such in Christ when the divine person of God's Son assumed it. Faced with this heresy, the fourth ecumenical council, at Chalcedon in 451, confessed: Following the holy Fathers, we unanimously teach and confess one and the same Son, our Lord Jesus Christ: the same perfect in divinity and perfect in humanity, the same truly God and truly man, composed of rational soul and body; consubstantial with the Father as to his divinity and consubstantial with us as to his humanity; "like us in all things but sin". He was begotten from the Father before all ages as to his divinity and in these last days, for us and for our salvation, was born as to his humanity of the virgin Mary, the Mother of God.91

And here is the kicker:

> We confess that one and the same Christ, Lord, and only-begotten Son, is to be acknowledged in two natures without confusion, change, division or separation. the distinction between the natures was never abolished by their union, but rather the character proper to each of the two natures was preserved as they came together in one person (prosopon) and one hypostasis.92
