And the glory which you gave me I have given them; that they may be one, even as we are one:

CHAPTER XII. That the Son is by Nature One with God His Father, though He says that He received, as by way of grace, His being One with the Father.
We say, and therein we are justified, that the Only-begotten hath an essential and natural unity with His Father, insomuch as He was both in the true sense begotten, and from Him proceeds, and is in Him: and though He seem in His own Person to have a separate and distinct Being, yet that He is accounted, by reason of His innate identity of Substance, as One with the Father. But since, in His Incarnation, on our behalf, in order to save our souls, He abdicated, as it were, that place which was His at the beginning, I mean His equality with God the Father, and appears to have been in some sort so far removed therefrom as to have stepped outside His invisible glory, for this is what is meant by the expression, He made Himself of no reputation, He that of old and from the very beginning was enthroned with the Father, receives this as a gift when in the Flesh; His earthy and mortal frame and human form, which was actually part of His Nature, of necessity requiring as a gift that which was His by Nature; for He was and is in the form of the Father, and in equality with Him. Though, therefore, the flesh from a woman's womb, that temple wherewith the Virgin endowed Him, was not in any wise consubstantial with God the Father, nor of like Nature with Him; yet, when once received into the Body of the Word, henceforth it was accounted as One with Him. For Christ is One, and the Son is One, even when He became Man. In this aspect of His Person He is conceived of as taken into union with the Father, being admitted thereto even in the Flesh, which originally enjoys not union with God. And, to speak more concisely and clearly, the Only-begotten says, that that which was given unto Him was given to His Flesh; given too, of course, wholly by the Father, through Himself, in the Spirit. For in no other way than this can union with God be effected, even in the case of Christ Himself, so far as He manifested Himself as, and indeed became, Man. The flesh, that is, was sanctified by union with the Spirit, the twain coming together in an ineffable way; and so unconfusedly attains to God the Word, and through Him to the Father, in habit of mind, that is, and not in any physical sense. This favour and glory then, He says, given unto Me, O Father, by Thee, that is, the glory of being One with Thee, I have given unto them, that they may be one, even as We are One.
