John 14:7

The Son reveals the knowledge of the Father through his own manifestation. For the manifestation of the Son is the knowledge of the Father, since all things are manifested through the Word.

And again, the Lord replied to Philip, who wished to behold the Father, "Have I been so long a time with you, and yet thou hast not known Me, Philip? He that sees Me, sees also the Father; and how sayest thou then, Show us the Father? For I am in the Father, and the Father in Me; and henceforth ye know Him, and have seen Him."

Wherefore? Because "I came forth from the Father, and am come into the world" and, "I am the way: no man cometh unto the Father, but by me; " and, "No man can come to me, except the Father draw him; " and, "All things are delivered unto me by the Father; " and, "As the Father quickeneth (the dead), so also doth the Son; " and again, "If ye had known me, ye would have known the Father also." For in all these passages He had shown Himself to be the Father's Commissioner, through whose agency even the Father could be seen in His works, and heard in His words, and recognised in the Son's administration of the Father's words and deeds.

(vii. de Trin) Or thus: When it is said that the Son is the way to the Father, is it meant that He is so by His teaching, or by His nature? We shall be able to see from what follows: If ye had known Me, ye should have known My Father also. In His incarnation asserting His Divinity, He maintained a certain order of sight and knowledge: separating the time of seeing from that of knowing. For Him, who He saith must be known, He speaks of as already seen: that henceforward they might from this revelation have knowledge of the Divine Nature which they had all along seen in Him.

How can knowledge of him be knowledge of the Father? For the apostles see him wearing the aspect of that human nature that belongs to him. But God is not encumbered with body and flesh and is unrecognizable by those who dwell in our weak and fleshly body. The answer is given by the Lord, who asserts that under the flesh that, in a mystery, he had taken, his Father’s nature dwells within him.… He makes a distinction between the time of seeing and the time of knowing. He says that from this time onward they shall know him whom they had already seen and so shall possess, from the time of this revelation onward, the knowledge of that nature on which, in him, they had gazed for so long.

It was not the carnal body that he had received by birth from the Virgin that could manifest to them the image and likeness of God. The human aspect that he wore could be no aid toward the mental vision of the incorporeal God. But God was recognized in Christ by those who recognized Christ as the Son on the evidence of the powers of his divine nature. And a recognition of God the Son produces a recognition of God the Father. For the Son is in such a sense the image as to be one in kind with the Father and yet in a way that indicates that the Father is his origin.

(Hom. lxxiii. 2) If the Jews, who wished to be separated from Christ, asked whither He was going, much more would the disciples, who wished never to be separated from Him, be anxious to know it. So with much love, and, at the same time, fear, they proceed to ask: Thomas saith unto Him, Lord, we know not whither Thou goest; and how can we know the way?

(Hom. lxxiii. 2) For if, He says, ye have Me for your guide to the Father, ye shall certainly come to Him. Nor can ye come by any other way. (c. 6:44) Whereas He had said above, No man can come to Me, except the Father draw him, now He says, No man cometh unto the Father but by Me, thus equalling Himself to the Father. The next words explain, Whither I go ye know, and the way ye know. If ye had known Me, He says, ye should have known My Father also; i. e. If ye had known My substance and dignity, ye would have known the Father's. They did know Him, but not as they ought to do. Nor was it till afterwards, when the Spirit came, that they were fully enlightened. On this account He adds, And from henceforth ye know Him, know Him, that is, spiritually. And have seen Him, i. e. by Me; meaning that he who had seen Him, had seen the Father. They saw Him, however, not in His pure substance, but clothed in flesh.

Connecting, therefore, His previous words with those that follow, He proceeded to say, "If ye had known me, ye should certainly have known my Father also." This conforms to His previous words, "No man cometh unto the Father but by me." And then He adds: "And from henceforth ye know Him, and have seen Him." But Philip, one of the apostles, not understanding what he had just heard, said, "Lord, show us the Father, and it sufficeth us." And the Lord replied to him, "Have I been so long time with you, and yet have ye not known me, Philip? he that seeth me, seeth also the Father."

Already, therefore, they knew the Son, if not all of them, those at least to whom it is said, "And whither I go ye know, and the way ye know;" for He is Himself the way. But they knew not the Father, and so have also to hear, "If ye have known me, ye have known my Father also;" that is, through me ye have known Him also. For I am one, and He another. But that they might not think Him unlike, He adds, "And from henceforth ye know Him, and have seen Him." For they saw His perfectly resembling Son, but needed to have the truth impressed on them, that exactly such as was the Son whom they saw, was the Father also whom they did not see. And to this points what is afterwards said to Philip, "He that seeth me, seeth also the Father." Not that He Himself was Father and Son, which is a notion of the Sabellians, who are also called Patripassians, condemned by the Catholic faith; but that Father and Son are so alike, that he who knoweth one knoweth both. For we are accustomed to speak in this way of two who closely resemble each other, to those who are in the habit of seeing one of them, and wish to know what like the other is, so that we say, In seeing the one, you have seen the other. In this way, then, is it said "He that seeth me, seeth also the Father." Not, certainly, that He who is the Son is also the Father, but that the Son in no respect disagrees with the likeness of the Father. For had not the Father and Son been two persons, it would not have been said, "If ye have known me, ye have known my Father also."

(Tr. lxix. 1) Our Lord had said that they knew both, Thomas says that they knew neither. Our Lord cannot lie; they knew not that they did know. Our Lord proves that they did: Jesus saith unto Him, I am the way, the truth, and the life.

(de Verb. Dom. s. liv) As if He said, I am the way, whereby thou wouldest go; I am the truth, whereto thou wouldest go; I am the life, in which thou wouldest abide. The truth and the life every one understands (capit); but not every one hath found the way. Even the philosophers of the world have seen that God is the life eternal, the truth which is the end of all knowledge. And the Word of God, which is truth and life with the Father, by taking upon Him human nature, is made the way. Walk by the Man, and thou wilt arrive at God. For it is better to limp on the right way, than to walk ever so stoutly by the wrong.

(Tr. lxix. 2) They knew then the way, because they knew He was the way. But what need to add, the truth, and the life? Because they were yet to be told whither He went. He went to the truth; He went to the life. He went then to Himself, by Himself. But didst Thou leave Thyself, O Lord, to come to us? (c. 3.). I know that Thou tookest upon Thee the form of a servant; by the flesh Thou camest, remaining where Thou wast; by that Thou returnedst, remaining where Thou hadst come to. If by this then Thou camest, and returnedst, by this Thou wast the way, not only to us, to come to Thee, but also to Thyself to come, and to return again. And when Thou wentest to life, which is Thyself, Thou raisedst that same flesh of Thine from death to life. Christ therefore went to life, when His flesh arose from death to life. And since the Word is life, Christ went to Himself; Christ being both, in one person, i. e. Word-flesh. Again, by the flesh God came to men, the truth to liars; for God is true, but every man a liar. When then He withdrew Himself from men, and lifted up His flesh to that place in which no liar is, the same Christ, by the way, by which He being the Word became flesh, by Himself, i. e. by His flesh, by the same returned to Truth, which is Himself, which truth, even amongst the liars He maintained unto death. Behold I myself, if I make you understand what I say, do in a certain sense go to you, though I do not leave myself. And when I cease speaking, I return to myself, but remain with you, if ye remember what ye have heard. If the image which God hath made can do this, how much more the Image which God hath begotten? Thus He goes by Himself, to Himself and to the Father, and we by Him, to Him and to the Father.

We have now the opportunity, dearly beloved, as far as we can, of understanding the earlier words of the Lord from the later, and His previous statements by those that follow, in what you have heard was His answer to the question of the Apostle Thomas. For when the Lord was speaking above of the mansions, of which He both said that they already were in His Father's house, and that He was going to prepare them; where we understood that those mansions already existed in predestination, and are also being prepared through the purifying by faith of the hearts of those who are hereafter to inhabit them, seeing that they themselves are the very house of God; and what else is it to dwell in God's house than to be in the number of His people, since His people are at the same time in God, and God in them? To make this preparation the Lord departed, that by believing in Him, though no longer visible, the mansion, whose outward form is always hid in the future, may now by faith be prepared: for this reason, therefore, He had said, "And if I go away and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also. And whither I go ye know, and the way ye know."

In reply to this "Thomas saith unto Him, Lord, we know not whither Thou goest: and how can we know the way?" Both of these the Lord had said that they knew; both of them this other declares that he does not know, to wit, the place to which, and the way whereby, He is going. But he does not know that he is speaking falsely; they knew, therefore, and did not know that they knew. He will convince them that they already know what they imagine themselves still to be ignorant of. "Jesus saith unto him, I am the way, and the truth, and the life." What, brethren, does He mean? See, we have just heard the disciple asking, and the Master instructing, and we do not yet, even after His voice has sounded in our ears, apprehend the thought that lies hid in His words. But what is it we cannot apprehend? Could His apostles, with whom He was talking, have said to Him, We do not know Thee? Accordingly, if they knew Him, and He Himself is the way, they knew the way; if they knew Him who is Himself the truth, they knew the truth; if they knew Him who is also the life, they knew the life. Thus, you see, they were convinced that they knew what they knew not that they knew.

What is it, then, that we also have not apprehended in this discourse? What else, think you, brethren, but just that He said, "And whither I go ye know, and the way ye know"? And here we have discovered that they knew the way, because they knew Him who is the way: the way is that by which we go; but is the way the place also to which we go? And yet each of these He said that they knew, both whither He was going, and the way. There was need, therefore, for His saying, "I am the way," in order to show those who knew Him that they knew the way, which they thought themselves ignorant of; but what need was there for His saying, "I am the way, and the truth, and the life," when, after knowing the way by which He went, they had still to learn whither He was going, but just because it was to the truth and to the life He was going? By Himself, therefore, He was going to Himself. And whither go we, but to Him, and by what way go we, but by Him? He, therefore, went to Himself by Himself, and we by Him to Him; yea, likewise both He and we go thus to the Father. For He says also in another place of Himself, "I go to the Father;" and here on our account He says, "No man cometh unto the Father but by me." And in this way, He goeth by Himself both to Himself and to the Father, and we by Him both to Him and to the Father.

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.

If ye had known Me, ye would have known My Father also.

Some may perchance say and think that the Son is here speaking of His own accord, and at His own suggestion. But it is not so. For He never uttered anything in an uncalled-for, or merely casual way; though He does occasionally repeat Himself in a most instructive manner, especially because of the utter inability of some to follow His teaching. But in the present instance His words are most profitable to us in connection with what He had said just before. For when Thomas questioned Him, asking: "Whither wilt Thou depart; or how can we know the way, if we know not whither Thou wilt go?" He thereupon answered him most effectively in the words: I am the Way, and the Life, and the Truth; and again: No man cometh unto the Father but by Me; thereby showing that if any one willed to know the way which would lead to eternal life, he would strive with all diligence to know Christ. But since it was likely that some, who had been trained in Jewish rather than in Evangelic doctrine, might suppose that a confession of faith in and a knowledge of One Person only out of all was sufficient for a right belief, and that it was needless to learn the doctrine concerning the Holy and Consubstantial Trinity; Christ seems to absolutely exclude those who hold this opinion from a true knowledge concerning God, unless they would also accept Himself. For it is through the Son that we must draw near to God the Father. For in a manner analogous to our acceptance of the Offspring, we shall arrive at our belief in the Parent also. For it is utterly impossible to doubt that a belief in the sonship of Son, as begotten of the essence of the Father, will certainly lead to a knowledge of the Father.

According then to the simpler and more obvious interpretation, He must be supposed to have spoken with this meaning: but if any one believes that He is employing subtle ideas so as to penetrate to the very root of the whole matter, he will find once more that the Son is teaching truth. The Divine Nature, indeed, is utterly incomprehensible by any human intellect; and to claim for oneself to have fully discovered Who and What in very essence the Creator of the universe is, would involve a display of absolute folly. Still, it is not impossible for us, though in a shadowy and uncertain manner, to obtain some kind of knowledge by holding up as a mirror to our mind's eye the catalogue of Divine attributes which are inherent by nature in the Son. For from a knowledge of what Christ is in Himself, and of the works He has wrought when He became Incarnate as well as before His Incarnation, one might afterwards ascend by analogous reasoning to a contemplation of the Father Who begat Him. Behold, I pray thee, the glory and the power that were His: gaze on His authority, that extended without hindrance over all. Tell me, is there anything conceivable or inconceivable that He does not appear to have achieved with perfect success at His own free will, both before and since His Incarnation? Nay, more, He Who showed Himself to us so mighty by the evidence of His works, says expressly: I and the Father are One, and: He that hath seen Me hath seen the Father. We must therefore, in reliance on what we have just quoted, pass onward from the Likeness to the Archetype, and from the Very Image to the full realisation of Him Whom the Very Image represents. We do not say, as some of the heterodox would have us say, that the Son is fashioned after the Father's likeness by means of certain attributes bestowed upon Him from without; nor even would we admit, as some in error suppose, that He is styled the Image of God the Father as possessing His glory, His power, and His wisdom, although being Himself really of a different nature: these are the foolish babblings of the heretics, sheer nonsense delicately veiled, or rather absolute impiety, designed according to their unholy and ungodly object to overthrow and destroy the doctrine of the Son's Consubstantiality with the Father. But Christ is a Son in very truth, begotten ineffably and incomprehensibly of the essence of God the Father, and as such is the Very Image and Likeness and Effulgence of Him, bearing innate within Himself the proper characteristics of His Father's essence, and possessing in all their beauty the attributes that are naturally the Father's. For we will not imitate the heretics in their extravagant madness, and degrade our own minds to such a depth of foolishness as to say that Christ in any respect differs from a Being Who is in very nature God, or to deny that He is begotten of the essence of God the Father, and so refuse to attribute to Him the glory of God; neither would we allow that any nature which was created and brought into existence out of nothing could ever, without undergoing change, be endowed with the Divine power and wisdom, or ever be such as the Divine and ineffable nature of God the Father may be imagined to be. For else, what distinction could any longer exist between the Creator and the creature; or what could intervene or sever, that is to say, between the thing made and Him Who made it, in regard to identity and essence? For if a creature possesses glory and power and wisdom exactly to the same degree as God the Father, I should be utterly unable to say, and I conceive the heretics would be in the same perplexity, wherein God's superiority can possibly consist, or how He can be greater than we or than His creature. Therefore we maintain that the Son is in no wise fashioned so as to resemble the Father by the addition of attributes from without, nor is He like a representation in a picture, adorned by us with merely ideal colours which gloss over and falsely indicate the royal dignity; but He is truly the Very Image and Likeness of His Father, displaying to us the Father's nature in clearest light by the graces that are His own by nature. And this is why Christ pronounces it impossible for any to have fully known the Father without first knowing Himself, that is, the Son.

How can our Lord say, If ye had known Me, ye should have known My Father also; when He has just said, Whither I go ye know, and the way ye know? We must suppose that some of them knew, and others not: among the latter, Thomas.
