Believe you not that I am in the Father, and the Father in me? the words that I speak unto you I speak not of myself: but the Father that dwells in me, he does the works.

Believest thou not that I am in the Father and the Father in Me?
"I indeed, O Philip," He would say, "in depicting in Myself the nature of My Father, am the Image of His essence, moulded as that implies after His likeness, not (as might be supposed) by the bestowal of glories that once were not Mine, nor even by the reflected brilliancy of Divine endowments that once were unfamiliar but have been granted from without: but rather in My own nature are contained the qualities peculiar to My Father; and whatsoever He may be, that in very truth am I, in regard to sameness in essence. To this thou wilt surely reply: for it seems thou didst not go on to realise that I am in the Father, and the Father in Me. And yet the force of my words shall constrain thee henceforth, even in spite of thyself, to acknowledge thy assent to this. Therefore, whatsoever I say is spoken as the words of the Father; and whatsoever I do, is done by the Father also." And Christ says this, not as one making use of the words of another, nor even as speaking in the office and capacity of a prophet to interpret the commands that came from the Father above: for the prophets ever spake, not their own words, but the words which they received by inspiration from God. Again, He attributes to His Father the successful performance of His miracles, not implying that He works His wonders by a power not His own, as did for instance those Apostles who said to the people: "Give not heed to us, as though by our own power or godliness we had healed the sick man." For the saints are wont to use no power of their own in working their miracles, but rather the power of God: for they appear as ministers and servants, showing forth the words and also the works of God. But since the Son is Consubstantial with the Father, differing from Him in no respect except as to distinct personality, He says that His own words are those of the Father, since the Father could in no wise make use of words differing from those of the Son. And further, thou wilt understand the same to be signified in the majesty of His works. For since the Father could never by any possibility carry into effect any work without the Son's knowledge and co-operation, Christ attributes His works to His Father. For consider Him as saying more clearly this: "I am in all respects like to Him Who begat Me, and an Image of His essence; not merely adorned with the outward appearance of a glory that is not Mine, but, owing to the identity of essence, containing within Myself My Father in all His fulness."
