Okay...now we are reaching things that are really hard for me to understand. Because the anathema says, clear as day, that expressions may not be divided between the natures on the grounds that some are fit to be applied to God, and yet you are saying that St. Cyril did just that in his defense of John?
The anathema does not say that expressions may not be divided between "natures", it says:
"If anyone shall divide between two persons or subsistences those expressions which are contained in the Evangelical and Apostolical writings, or which have been said concerning Christ by the Saints, or by himself, and shall apply some to him as to a man separate from the Word of God, and shall apply others to the only Word of God the Father, on the ground that they are fit to be applied to God: let him be anathema."
Here is where Cyril defended the EOs on this account in detail: In his letter to Acacius, bishop of Melitene, Saint Cyril wrote:
But the brethren at Antioch, understanding in simple thoughts only those from which Christ is understood to be, have maintained a difference of natures, because, as I said, divinity and humanity are not the same in natural quality, but proclaimed one Son and Christ and Lord as being truly one; they say His person is one, and in no manner do they separate what has been united.
Neither do they admit the natural division as the author of the wretched inventions [Nestorius] was pleased to think, but they strongly maintain that only the sayings concerning the Lord are separated, not that they say that some of them separately are proper to the son, the Word of God the Father and others are proper to another one again, the one from a woman, but they say that some are proper to His divinity and others are proper to His humanity. For the same one is God and man. But they say that there are others which have been made common in a certain way and, as it were, look towards both, I mean both the divinity and the humanity.
This letter is from an OO Bishop's essay:

The only way to reconcile them is by saying that dividing the expressions between two forms does not mean that the two forms are separate persons.
We really need to be flexible in our thinking like Cyril was about the Antiochians in order to grasp and reconcile these kinds of distinctions.
...
It is His humanity which allowed Him to become a sacrifice for us all, so in that sense it would be appropriate to say (and is said) that He suffered according to His humanity, but "in" it?
Sure, he suffered "in" his flesh, hence "in" his humanity. I do not have mental trouble with that phrase, nor do the Coptic writers I cited.
St. Cyril writes in Letter 46
Your excellency very rightly and with complete understanding has expounded the matter concerning the Passion of our Savior, by strongly contending that the only-begotten Son of God in so far as he is known to be and is God DID NOT ENDURE THE SUFFERINGS OF THE BODY IN HIS OWN NATURE, BUT SUFFERED RATHER IN HIS EARTHLY NATURE. For it was necessary and proper to maintain with reference to the one true Son both that he did not suffer in his divinity and that it is affirmed that he suffered in his humanity, for his flesh suffered.
Would you agree that it is helpful be flexible in thinking post-incarnation mainstream dyophysite language like Cyril was?
The two natures exist by the simple fact that humanity and divinity, which our Lord is composed of, are not the same nature. They're different natures, and we do not confuse them by mixture, separation, dissolving, or any other way. So our Lord is from two natures by virtue of the fact that He is of humanity ('has his human nature', if you will) according to St. Mary His mother, and of divinity ('has his divine will') from God the Father. By Christ's existence in the flesh He has both natures. We just do not say He is 'in' two natures because again our understanding of the incarnation does not permit it without destroying the unity of the incarnation in the first place, so it's not possible.
The fact that you use "exist" in the present tense, speaking of two natures, and saying "He has both natures" are statements by you that I agree with. The ease and common sense way that you put those phrases reflect to me that Christ does in fact, as a matter of common, normal speech, "have two natures."
A big tragic problem, Dzheremi, is that this very issue has been a major dividing point between our churches.
Severus of Antioch wrote:
When we anathematise those who say Emmanuel has two natures after the union, and speak of the activities and properties of these, we are not saying this as subjecting to anathema the fact of, or naming, natures, or activities, or properties, but speaking of two natures after the union, and because consequent ly those natures...are divided completely and in everything
