yes, divine and human by nature, not by Person.
There is no such thing as nature without corresponding hypostasis any more than there is such a thing as species without specimens. It's like having a blanket dyed red and saying, "The blanket's redness is red, but the blanket itself is not red." That's Platonist gobbledygook. Human nature
doesn't exist except as humans.
yes, He became man, but our hymns over and over again say that this was not by any change to what He was before.
That is correct, his divinity did not change. The manhood was an addition to his divinity, not an alteration of his divinity.
not to mention, St Cyril flat out rejects in the Formula of Reunion that the Person of the Word changed. the addition of humanity is with no change to the Logos.
The Person of the Word didn't change in terms of his divinity being altered or transformed. He only "changed" in the sense of taking on humanity in addition. This is not an alteration to what the Word is eternally and was before, but is rather a temporal
incorporation which does not compromise the
integrity of the divine word.
yeah, that is not what this is about. we are talking about the qualities of being Divine. which St John says the Son has exactly like the Father. so the Person of the Word is unchanging, as is the Person of the Father and the Spirit. St Leo's Tome also affirms this, that whatever property the Logos had in both Divinity and humanity, He maintained. so the Divine Person does not change. yes, assumes humanity and becomes what He was not, but this is not by any alteration to His Person or to Divinity,
This depends on how you are defining alteration. There was absolutely not alteration the sense of the integrity of the Word of God and the Word's divinity being compromised. If you are saying there was not alteration in the sense that the Word did not become man, that the Word
isn't man as truly as He is God, then I don't agree with that and neither does John of Damascus. John says his
person itself is compound, that is,
comprised of two elements. If the Word is not human, then his person would NOT be compound, but simple; we'd only be talking about his natures. But, again, nature does not exist without hypostasis. Hypostasis IS existence; if Christ's humanity doesn't have a hypostasis (the Word), then it literally
doesn't have an existence. You are saying Christ's nature is human and divine, but his
existence is only divine; this doesn't make any sense. A nature unless it has existence is purely imaginary...like munchkin nature, which has no hypostases.
