And I have declared unto them your name, and will declare it: that the love with which you have loved me may be in them, and I in them.

Cyril of Alexandria
AD 444
He says that knowledge of God the Father was at once in Him and in the disciples who attended Him. And, lest any man should be beguiled into gross extravagances of opinion, and think that His disciples had this knowledge in an equal degree with Himself, Christ at once distinguishes between them and Himself, and makes the difference very clear, showing that He revealed God unto them, while they, through Him, received knowledge. For our Lord Jesus Christ, as He is the Word, and Counsel, and Wisdom of the Father, intuitively knows what is in Him, and concerns Himself about His Father's most secret thoughts; just as, indeed, the mind of a man knows what is in him, and as nothing that is in our hearts is hidden from our human understanding. The inspired disciples, on the other hand, do not enjoy, as the fruit of their own understanding, the ability to form any conception about God; but, through the light of the Spirit, lay hold of the true meaning of the mysteries of the Son, and so are enabled to know the Father. Very appropriately, then, and to our profit, Christ added the words: And I made known unto them Thy Name, and will make it known.
Observe, too, how Both Persons, I mean the Father and the Son, effectually work together to make the Godhead comprehensible to men. For the Father makes us wise by revealing to us His own Son, and none the less also the Son makes us wise by revealing to us the Father. To the blessed Peter, moreover, He spake these words, about the parts of Caesarea called Philippi: Blessed art thou, Simon Bar-jona; for flesh and blood hath not revealed it unto thee, but My Father Which is in heaven. For the disciple confessed and maintained his belief that He was Christ, the Son of the living God. And now He says, concerning Himself: I made known unto them Thy Name, and will make it known. For the Only-begotten ceaseth not to reveal unto us the meaning of the mystery concerning Himself, as He revealed it to His first followers at the beginning; and this He doeth continually, implanting in each of us the light of the Spirit, and guiding those that love Him to knowledge of those things which pass their understanding and conception. What His purpose is, and what kind of benefit He will confer on us by His declaration that He had already revealed the Father unto the disciples, and would also make Him known to their successors, He pointed out to us, when He said, that the love wherewith Thou lovedst Me may be in them, and I in them. For they who have been able, by purity of thought, to know God the Father, and have been throughly instructed in the knowledge of the mystery that is in Christ, will wholly gain and indisputably enjoy the perfect love of the Father, like unto the Son. For the Father loves His Son with a perfect love; and Christ also Himself abideth in Him, through the Holy Spirit, uniting, through Himself, into spiritual fellowship with God the Father him that knows Him, and is in travail, as it were, with the unperverted word of Divine Truth. He makes known to us the Name of the Father by declaring to us Himself, Who is His Son. For hand in hand with the knowledge of Him That was begotten will be closely linked the knowledge of Him That begat Him, just as the converse is also true. And if the saying is true, and to be accepted without question, that the conception of the Son is necessarily implied in that of the Father, and so also the conception of the Father in that of the Son, and the knowledge of One is contained in the knowledge of the Other; how can the Son any more be a creature, as some impious men say? For if a man speak of the Son, he thereby instils the idea of a Father in his hearers; while if he were to call Him a creature, he leads them on to the conception of a maker. But as the Son calls God Father, not Maker or Creator, He is clearly conscious that He is Himself in fact a Son. Therefore the Son is deemed, and is, a Son, and not a creature, as they say, which would imply that He That made Him was His Creator, and not His Father. And the force of the argument will be no whit damaged by the fact, that the title of child or son is accounted human. For the attributes which peculiarly and especially belong to Him, as being by Nature the Son of God His Father, these were brought down even to us; Holy Writ often so applying them on occasion, and at times investing those who are sons by adoption with the attributes of a son by nature. And it is no marvel, if we also have obtained the title of son, and that God has thus chosen to honour us in His loving-kindness, as He has even called those gods who are avowedly sprung from the earth.
