If you had known me, you would have known my Father also: and from henceforth you know him, and have seen him.
All Commentaries on John 14:7 Go To John 14
Cyril of Alexandria
AD 444
And from henceforth ye know Him, and have seen Him.
Wonderful, it seems to me, is the gracious intention and the unspeakably profound purpose that underlies this saying also. For after having just said: If ye had known Me, ye would have known My Father also, and seeming thus to reproach His disciples for their ignorance of truths so essential, He immediately passes on to comfort them with the assurance: From henceforth ye know Him and have seen Him. For since they were destined to become rulers of the Churches throughout the world, in obedience to the Saviour's commission: Go ye and make disciples of all nations, for this reason above all others, as I think, He first utters a most useful truth of universal reference to all time, that whosoever knoweth the Son will most assuredly also know God the Father of Whom the Son is begotten; and then in His kindness He goes on to testify that His disciples possess this knowledge: not speaking at all by way of compliment, for He could never utter aught but truth, but inasmuch as they really knew Him and had most fully acknowledged Him. For that they knew and had believed that the Lord was really Son of God can by no means be a matter of doubt to right-minded persons. For how came it that Nathaniel the Israelite, when he heard Christ say: Before that Philip called thee, when thou wast under the fig-tree, I saw thee, immediately put forth his full confession of faith, saying: Rabbi, Thou art the Son of God, Thou art the King of Israel? Moreover, when the sea was marvellously and supernaturally calmed, how was it that those who were in the ship worshipped Him, saying: Truly Thou art the Son of God? Will any one maintain that this saying was uttered by men who did not know that He was God and begotten of God the Father? Surely such an one would give a most convincing proof of his want of intelligence. When, in the district of Caesarea Philippi, they were asked by Christ Himself: Who do men say that I the Son of Man am? did not they first of all give the opinions of others? Some, they say, think Thou art Elijah, and others Jeremiah, or one of the prophets. But Who they themselves said that He was, they shrank not from telling Him plainly, all speaking by the mouth of their chief, and that was Peter, affirming positively: Thou art the Christ, the Son of the Living God. Yet when Christ says: If ye had known Me, ye would have known My Father also, do not suppose that the saying is uttered entirely for the sake of the disciples: it is rather a general declaration laid down for all, the holy disciples being taken as representatives of all mankind.
Notice carefully then how clearly we shall find that they have not been ignorant that He is God and the Son of God; but when He spoke of Himself as "the Way" of God, then they did not understand what seemed to be spoken enigmatically: and this will comprise the full extent of any charge of ignorance that can be brought against them. For this reason surely, having briefly refuted the idea of their inability to understand what was told them indirectly, and then grounded on this a declaration affecting all men, teaching plainly that whosoever knows not the Son will also lose his knowledge of the Father; He then most justly testifies to the disciples' knowledge of Him, inasmuch as they had already made open confession of their faith: and this He does in the words: From henceforth ye know Him and have seen Him. And He uses the word "henceforth," not with reference to that hour or that day on which He was uttering His teaching on these matters: but He uses the word in order to contrast with the days of the old and first dispensation the new and recently-arisen season of His own presence, whereby the knowledge of the Father as seen through the Son has been made clearer for all men throughout the world. Therefore also in the Book of Psalms, as speaking to God the Father, He says: The knowledge of Thee has been greatly magnified by Me. For having seen the Son excelling in deeds incredibly marvellous, and with God-befitting authority easily accomplishing His own good pleasure, we have been led on thereby to accept in reverent admiration the knowledge of the Father, believing it to be no other than the knowledge of the Son Who came forth from Him. From henceforth, therefore, ye know Him and have seen Him. For through the Son we have been led, as I said just now, to know Who the Father is, and not only have we known, but we have also beheld or seen. For knowledge indicates that mental contemplation at which one may very well arrive concerning the Divine and ineffable nature that is above all, and through all, and in all. But to have seen the Truth signifies the fulfilment of our knowledge by the vision of the miraculous works. For we have not simply known the bare fact that the Father is in His nature Life; nor have we had within ourselves the knowledge of the matter ideally and theoretically only: we have seen the truth carried out by the Son, in giving life to the dead, and restoring to existence those who had seen corruption. We have not simply known the fact that the God and Father of all is in His nature Life, and has the whole creation in subjection beneath His feet; and that He rules in sovereign authority over all things made by Him, so that, as it is written: All His works shake and tremble at Him, we have seen evidence of the truth in the action of the Son, when, in rebuking the sea and the winds, He said with all authority, Peace, be still.
Since therefore He was intending to say that "you have not only known, but have even seen the Father," He considered it essential to prefix the word "henceforth;" and why so? The reason was this: the law of Moses declared to the children of Israel, The Lord thy God is one Lord, and never offered the doctrine concerning the Son to the men of old time; it was content with driving them away from the worship of many gods and calling them to adore One, and One only: but our Lord Jesus the Christ by His Incarnation made known to us the Father through Himself by many signs and mighty works, and has shown that the nature of the Godhead which we believe to be contained in the Holy Trinity is in truth One. And so He does well to say "henceforth," on account of the imperfection of knowledge possessed by those who walk after the law, and order their lives in that system. And we must note well that in saying that He Himself and not the Father has been seen, He in no way denies the real and individual existence of the God and Father from Whom He is; nor does He even say that He Himself is the Father, inasmuch as He claims to have come to represent the Father's Person. But since He is Consubstantial with the Father, He says that His Father is seen in His Person; just as if an ordinary man's son, wishing to indicate plainly the nature of his father, were to point to himself and say to any chance inquirer in the matter: "In me thou hast seen my father." Here again, however, the Godhead will entirely transcend the power of the example to illustrate.
