Dialogus de unione personali duarum in Christo naturarum secundum mentem Sacrae Scripturae, Ecclesiae, atque Augustanae Confessionis adversus eos qui genuinam horum sententiam pervertunt

not a divine property but a human one. For the human nature kept its own properties), we would not call it a verbal communication in the person without impiety. For it is not mere words, but the very truth, that God died, the son of man is the creator, eternal, and the son of the living God, Matt 16:16.

But in the natures, not even a verbal communication of essentials can be established. For Humanity can no more become God through some communication of divine properties than the Deity can die. For the properties of neither nature go beyond their own subjects; and therefore the Deity could no more communicate infinite Omnipotence, αὐτουσίαν self-existence, or Eternity (for these are essential properties of the divine nature) to the Humanity than the human nature could communicate Passion to the Deity; nor can something be made either omnipotent or infinite (for Infinity and Omnipotence cohere, etc.) any more than something can become an accidental God.

Damascenus, Book 3, Chapter 3: How could one nature be the receiver of contrary substantial differences? For how is it possible for the same nature, according to the same respect, to be created and uncreated, mortal and immortal, circumscribed and uncircumscribed?

ERIST. Sacred Scripture indicates to us a distinction in the communication of properties. For when it speaks of the human nature, it attributes to it what is its own, as when Peter says Christ died in the flesh: 1 Pet. 3:18, but does not say Christ is with us by his Deity, as if the human nature ought to be excluded. This, therefore, is to be understood concerning both natures; and the communicatio idiomatum will not be reciprocal.

ORTH. On the contrary, that the communication of properties is mutual or reciprocal, that is, that Christ is Man in no other reason than God is Man, and that the Deity communicated divine properties to the Humanity no more than the Humanity communicated human ones to the Deity (which you deny), I will prove with examples from Scripture and
