Without detriment therefore to the properties of either nature and substance which then came together in one person, majesty took on humility, strength weakness, eternity mortality: and for the paying off of the debt belonging to our condition inviolable nature was united with possible nature, so that, as suited the needs of our case, one and the same Mediator between God and men, the Man Christ Jesus, could both die with the one and not die with the other. Thus in the whole and perfect nature of true man was true God born, complete in what was His own, complete in what was ours.

And by “ours” we mean what the Creator formed in us from the beginning and what He undertook to repair. For what the Deceiver brought in and man deceived committed, had no trace in the Saviour. Nor, because He partook of man's weaknesses, did He therefore share our faults. He took the form of a slave without stain of sin, increasing the human and not diminishing the divine: because that emptying of Himself whereby the Invisible made Himself visible and, Creator and Lord of all things though He be, wished to be a mortal, was the bending down of pity, not the failing of power.

Accordingly He who while remaining in the form of God made man, was also made man in the form of a slave. For both natures retain their own proper character without loss: and as the form of God did not do away with the form of a slave, so the form of a slave did not impair the form of God. For inasmuch as the Devil used to boast that man had been cheated by his guile into losing the divine gifts, and bereft of the boon of immortality had undergone sentence of death, and that he had found some solace in his troubles from having a partner in delinquency, and that God also at the demand of the principle of justice had changed His own purpose towards man whom He had created in such honour: there was need for the issue of a secret counsel, that the unchangeable God whose will cannot be robbed of its own kindness, might carry out the first design of His Fatherly care towards us by a more hidden mystery; and that man who had been driven into his fault by the treacherous cunning of the devil might not perish contrary to the purpose of God.
