6 But, as we pointed out in the former books, they seize the Dispensation of the assumed manhood as a pretext to dishonour His divinity, and distort the Mystery of our salvation into an occasion of blasphemy. Had they held fast the faith of the Apostle, they would neither have forgotten that He, Who was in the form of God, took the form of a servant, nor made use of the servant's form to dishonour the form of God (for the form of God includes the fullness of divinity), but they would have noted, reasonably and reverently, the distinction of occasions and mysteries, without dishonouring the divinity, or being misled by the Incarnation of Christ.
But now, when we have, I am convinced, proved everything to the utmost, and pointed out the power of the divine nature underlying the birth of the assumed body, there is no longer room for doubt. He Who was at once man and the Only-begotten God performed all things by the power of God, and in the power of God accomplished all things through a true human nature. As begotten of God He possessed the nature of divine omnipotence, as born of the Virgin He had a perfect and entire humanity. Though He had a real body, He subsisted in the nature of God, and though He subsisted in the nature of God, He abode in a real body.
