Commentary on John 17 verses 20–23
Next to their purity he prays for their unity; for the wisdom from above is first pure, then peaceable; and amity is amiable indeed when it is like the ointment on Aaron's holy head, and the dew on Zion's holy hill. Observe,
I. Who are included in this prayer (Joh 17:20): "Not these only, not these only that are now my disciples" (the eleven, the seventy, with others, men and women that followed him when he was here on earth), "but for those also who shall believe on me through their word, either preached by them in their own day or written by them for the generations to come; I pray for them all, that they all may be one in their interest in this prayer, and may all receive benefit by it." Note, here, 1. Those, and those only, are interested in the mediation of Christ, that do, or shall, believe in him. This is that by which they are described, and it comprehends all the character and duty of a Christian. They that lived then, saw and believed, but they in after ages have not seen, and yet have believed. 2. It is through the word that souls are brought to believe on Christ, and it is for this end that Christ appointed the scriptures to be written, and a standing ministry to continue in the church, while the church stands, that is, while the world stands, for the raising up of a seed. 3. It is certainly and infallibly known to Christ who shall believe on him. He does not here pray at a venture, upon a contingency depending on the treacherous will of man, which pretends to be free, but by reason of sin is in bondage with its children; no, Christ knew very well whom he prayed for, the matter was reduced to a certainty by the divine prescience and purpose; he knew who were given him, who being ordained to eternal life, were entered in the Lamb's book, and should undoubtedly believe, Act 13:48. 4. Jesus Christ intercedes not only for great and eminent believers, but for the meanest and weakest; not for those only that are to be employed in the highest post of trust and honour in his kingdom, but for all, even those that in the eye of the world are inconsiderable. As the divine providence extends itself to the meanest creature, so does the divine grace to the meanest Christian. The good Shepherd has an eye even to the poor of the flock. 5. Jesus Christ in his mediation had an actual regard to those of the chosen remnant that were yet unborn, the people that should be created (Psa 22:31), the other sheep which he must yet bring. Before they are formed in the womb he knows them (Jer 1:5), and prayers are filed in heaven for them beforehand, by him who declareth the end from the beginning, and calleth things that are not as though they were.
II. What is intended in this prayer (Joh 17:21): That they all may be one. The same was said before (Joh 17:11), that they may be one as we are, and again, Joh 17:22. The heart of Christ was much upon this. Some think that the oneness prayed for in Joh 17:11 has special reference to the disciples as ministers and apostles, that they might be one in their testimony to Christ; and that the harmony of the evangelists, and concurrence of the first preachers of the gospel, are owing to this prayer. Let them be not only of one heart, but of one mouth, speaking the same thing. The unity of the gospel ministers is both the beauty and strength of the gospel interest. But it is certain that the oneness prayed for in Joh 17:21 respects all believers. It is the prayer of Christ for all that are his, and we may be sure it is an answered prayer - that they all may be one, one in us (Joh 17:21), one as e are one (Joh 17:22), made perfect in one, Joh 17:23. It includes three things: -
1.That they might all be incorporated in one body. "Father, look upon them all as one, and ratify that great charter by which they are embodied as one church. Though they live in distant places, from one end of heaven to the other, and in several ages, from the beginning to the close of time, and so cannot have any personal acquaintance or correspondence with each other, yet let them be united in me their common head." As Christ died, so he prayed, to gather them all in one, Joh 11:52; Eph 1:10.
2.That they might all be animated by one Spirit. This is plainly implied in this - that they may be one in us. Union with the Father and Son is obtained and kept up only by the Holy Ghost. He that is joined to the Lord in one spirit, Co1 6:17. Let them all be stamped with the same image and superscription, and influenced by the same power.
3.That they might all be knit together in the bond of love and charity, all of one heart. That they all may be one, (1.) In judgment and sentiment; not in every little thing - this is neither possible nor needful, but in the great things of God, and in them, by the virtue of this prayer, they are all agreed - that God's favour is better than life - that sin is the worst of evils, Christ the best of friends - that there is another life after this, and the like. (2.) In disposition and inclination. All that are sanctified have the same divine nature and image; they have all a new heart, and it is one heart. (3.) They are all one in their designs and aims. Every true Christian, as far as he is so, eyes the glory of God as his highest end, and the glory of heaven as his chief good. (4.) They are all one in their desires and prayers; though they differ in words and the manner of expressions, yet, having received the same spirit of adoption, and observing the same rule, they pray for the same things in effect. (5.) All one in love and affection. Every true Christian has that in him which inclines him to love all true Christians as such. That which Christ here prays for is that communion of saints which we profess to believe; the fellowship which all believers have with God, and their intimate union with all the saints in heaven and earth, Jo1 1:3. But this prayer of Christ will not have its complete answer till all the saints come to heaven, for then, and not till then, they shall be perfect in one, Joh 17:23; Eph 4:13.
III. What is intimated by way of plea or argument to enforce this petition; three things: -
1.The oneness that is between the Father and the Son, which is mentioned again and again, Joh 17:11, Joh 17:21-23. (1.) It is taken for granted that the Father and Son are one, one in nature and essence, equal in power and glory, one in mutual endearments. The Father loveth the Son, and the Son always pleased the Father. They are one in design, and one in operation. The intimacy of this oneness is expressed in these words, thou in me, and I in thee. This he often mentions for his support under his present sufferings, when his enemies were ready to fall upon him, and his friends to fall off from him; yet he was in the Father, and the Father in him. (2.) This is insisted on in Christ's prayer for his disciples' oneness, [1.] As the pattern of that oneness, showing how he desired they might be one. Believers are one in some measure as God and Christ are one; for, First, The union of believers is a strict and close union; they are united by a divine nature, by the power of divine grace, in pursuance of the divine counsels. Secondly, It is a holy union, in the Holy Spirit, for holy ends; not a body politic for any secular purpose. Thirdly, It is, and will be at last, a complete union. Father and Son have the same attributes, properties, and perfections; so have believers now, as far as they are sanctified, and when grace shall be perfected in glory they will be exactly consonant to each other, all changed into the same image. [2.] As the centre of that oneness; that they may be one in us, all meeting here. There is one God and one Mediator; and herein believers are one, that they all agree to depend upon the favour of this one God as their felicity and the merit of this one Mediator as their righteousness. That is a conspiracy, not a union, which doth not centre in God as the end, and Christ as the way. All who are truly united to God and Christ, who are one, will soon be united one to another. [3.] As a plea for that oneness. The Creator and Redeemer are one in interest and design; but to what purpose are they so, if all believers be not one body with Christ, and do not jointly receive grace for grace from him, as he has received it for them? Christ's design was to reduce revolted mankind to God: "Father," says he, "let all that believe be one, that in one body they may be reconciled" (Eph 2:15, Eph 2:16), which speaks of the uniting of Jews and Gentiles in the church; that great mystery, that the Gentiles should be fellow-heirs, and of the same body (Eph 3:6), to which I think this prayer of Christ principally refers, it being one great thing he aimed at in his dying; and I wonder none of the expositors I have met with should so apply it. "Father, let the Gentiles that believe be incorporated with the believing Jews, and make of twain one new man." Those words, I in them, and thou in me, show what that union is which is so necessary, not only to the beauty, but to the very being, of his church. First, Union with Christ: I in them. Christ dwelling in the hearts of believers is the life and soul of the new man. Secondly, Union with God through him: Thou in me, so as by me to be in them. Thirdly, Union with each other, resulting from these: that they hereby may be made perfect in one. We are complete in him.
2.The design of Christ in all his communications of light and grace to them (Joh 17:22): "The glory which thou gavest me, as the trustee or channel of conveyance, I have accordingly given them, to this intent, that they may be one, as we are one; so that those gifts will be in vain, if they be not one." Now these gifts are either, (1.) Those that were conferred upon the apostles, and first planters of the church. The glory of being God's ambassadors to the world - the glory of working miracles - the glory of gathering a church out of the world, and erecting the throne of God's kingdom among men - this glory was given to Christ, and some of the honour he put upon them when he sent them to disciple all nations. Or, (2.) Those that are given in common to all believers. The glory of being in covenant with the Father, and accepted of him, of being laid in his bosom, and designed for a place at his right hand, was the glory which the Father gave to the Redeemer, and he has confirmed it to the redeemed. [1.] This honour he says he hath given them, because he hath intended it for them, settled it upon them, and secured it to them upon their believing Christ's promises to be real gifts. [2.] This was given to him to give to them; it was conveyed to him in trust for them, and he was faithful to him that appointed him. [3.] He gave it to them, that they might be one. First, to entitle them to the privilege of unity, that by virtue of their common relation to one God the Father, and one Lord Jesus Christ, they might be truly denominated one. The gift of the Spirit, that great glory which the Father gave to the Son, by him to be given to all believers, makes them one, for he works all in all, Co1 12:4, etc. Secondly, To engage them to the duty of unity. That in consideration of their agreement and communion in one creed and one covenant, one Spirit and one Bible - in consideration of what they have in one God and one Christ, and of what they hope for in one heaven, they may be of one mind and one mouth. Worldly glory sets men at variance; for if some be advanced others are eclipsed, and therefore, while the disciples dreamed of a temporal kingdom, they were ever and anon quarrelling; but spiritual honours being conferred alike upon all Christ's subjects, they being all made to our God kings and priests, there is no occasion for contest nor emulation. The more Christians are taken up with the glory Christ has given them, the less desirous they will be of vain-glory, and, consequently, the less disposed to quarrel.
3.He pleads the happy influence their oneness would have upon others, and the furtherance it would give to the public good. This is twice urged (Joh 17:21): That the world may believe that thou hast sent me. And again (Joh 17:23): That the world may know it, for without knowledge there can be no true faith. Believers must know what they believe, and why and wherefore they believe it. Those who believe at a venture, venture too far. Now Christ here shows,
(1.)His good-will to the world of mankind in general. Herein he is of his Father's mind, as we are sure he is in every thing, that he would have all men to be saved, and to come to the knowledge of the truth, Ti1 2:4; Pe2 3:9. Therefore it is his will that all means possible should be used, and no stone left unturned, for the conviction and conversion of the world. We know not who are chosen, but we must in our places do our utmost to further men's salvation, and take heed of doing any thing to hinder it.
(2.)The good fruit of the church's oneness; it will be an evidence of the truth of Christianity, and a means of bringing many to embrace it.
[1.]In general, it will recommend Christianity to the world, and to the good opinion of those that are without. First, The embodying of Christians in one society by the gospel charter will greatly promote Christianity. When the world shall see so many of those that were its children called out of its family, distinguished from others, and changed from what they themselves sometimes were, - when they shall see this society raised by the foolishness of preaching, and kept up by miracles of divine providence and grace, and how admirably well it is modelled and constituted, they will be ready to say, We will go with you, for we see that God is with you. Secondly, The uniting of Christians in love and charity is the beauty of their profession, and invites others to join with them, as the love that was among those primo-primitive Christians, Act 2:42, Act 2:43; Act 4:32, Act 4:33. When Christianity, instead of causing quarrels about itself, makes all other strifes to cease, - when it cools the fiery, smooths the rugged, and disposes men to be kind and loving, courteous and beneficent, to all men, studious to preserve and promote peace in all relations and societies, this will recommend it to all that have any thing either of natural religion or natural affection in them.
[2.]In particular, it will beget in men good thoughts, First, Of Christ: They will know and believe that thou hast sent me, By this it will appear that Christ was sent of God, and that his doctrine was divine, in that his religion prevails to join so many of different capacities, tempers, and interests in other things, in one body by faith, with one heart by love. Certainly he was sent by the God of power, who fashions men's hearts alike, and the God of love and peace; when the worshippers of God are one, he is one, and his name one. Secondly, Of Christians: They will know that thou hast loved them as thou hast loved me. Here is, 1. The privilege of believers: the Father himself loveth them with a love resembling his love to his Son, for they are loved in him with an everlasting love. 2. The evidence of their interest in this privilege, and that is their being one. By this it will appear that God loves us, if we love one another with a pure heart; for wherever the love of God is shed abroad in the heart it will change it into the same image. See how much good it would do to the world to know better how dear to God all good Christians are. The Jews had a saying, If the world did but know the worth of good men, they would hedge them about with pearls. Those that have so much of God's love should have more of ours.
"That they all may be one; as Thou, Father, art in Me, and I in Thee, that they also may be one in Us: that the world also may believe that Thou hast sent Me. And the glory which Thou hast given Me I have given them; that they may be one, as We are one: I in them, and Thou in Me, that they may be made perfect in one."
(viii. de Trin) By this giving and receiving of honour, then, all are one. But I do not yet apprehend in what way this makes all one. Our Lord, however, explains the gradation and order in the consummating of this unity, when He adds, I in them, and Thou in Me; so that inasmuch as He was in the Father by His divine nature, we in Him by His incarnation, and He again in us by the mystery of the sacrament, a perfect union by means of a Mediator was established.
There are some … who in their desire to deny the unity of the divine substance try to make light of the love of the Father and the Son, because it is written, “You have loved them, as you have loved me.” But when they say this, what else do they do but adopt a likeness of comparison between the Son of God and human beings? Can we indeed be loved by God as the Son is, in whom the Father is well-pleased? The Son is well-pleasing in himself; we are well-pleasing through him. For those in whom God sees his own Son after his own likeness, he admits through his Son into the favor of sons [children]. As we go through likeness unto likeness, in the same way, we are called to adoption through the generation of the Son. The eternal love of God’s nature is one thing; that of grace is another. And if they start a debate on the words that are written, “And you have loved them, as you have loved me,” and think a comparison is intended, they must think that the following also was said by way of comparison, “Be merciful, as your Father who is in heaven is merciful.” It is also elsewhere said, “Be perfect, as my Father who is in heaven is perfect.” But if he is perfect in the fullness of his glory, we are but perfect according to the growth of virtue within us. The Son also is loved by the Father according to the fullness of a love that always remains in him, but in us growth in grace merits the love of God. You see, then, how God has given grace to humankind, and do you want to separate the natural and indivisible love of the Father and the Son? And do you still strive to make nothing of words, where you note the mention of a unity of majesty?
"That they may be made perfect in one, and that the world may know that Thou hast sent Me." He saith these latter words immediately after the other, to show that peace hath more power to attract men than a miracle; for as it is the nature of strife to separate, so it is that of agreement to weld together. "And I have loved them as Thou hast loved Me." Here again the "as" means, as far as it is possible for a man to be loved; and the sure proof of His love is His giving Himself for them. After having told them that they shall be in safety, that they shall not be overturned, that they shall be holy, that many shall believe through them, that they shall enjoy great glory, that not He alone loved them, but the Father also; He next telleth them of what shall be after their sojourning here, concerning the prizes and crowns laid up for them.
"I in them, and Thou in Me." "How gave He the glory?" By being in them, and having the Father with Him, so as to weld them together. But in another place He speaketh not so; He saith not that the Father cometh by Him, but, "that He and the Father come, and take up their abode with him," "there" removing the suspicion of Sabellius, "here" that of Arius.
The love, therefore, wherewith God loveth, is incomprehensible and immutable. For it was not from the time that we were reconciled unto Him by the blood of His Son that He began to love us; but He did so before the foundation of the world, that we also might be His sons along with His Only-begotten, before as yet we had any existence of our own. Let not the fact, then, of our having been reconciled unto God through the death of His Son be so listened to or so understood, as if the Son reconciled us to Him in this respect, that He now began to love those whom He formerly hated, in the same way as enemy is reconciled to enemy, so that thereafter they become friends, and mutual love takes the place of their mutual hatred; but we were reconciled unto Him who already loved us, but with whom we were at enmity because of our sin. Whether I say the truth on this, let the apostle testify, when he says: "God commendeth His love toward us, in that, while we were yet sinners, Christ died for us." He, therefore, had love toward us even when we were practising enmity against Him and working iniquity; and yet to Him it is said with perfect truth, "Thou hatest, O Lord, all workers of iniquity." Accordingly, in a wonderful and divine manner, even when He hated us, He loved us; for He hated us, in so far as we were not what He Himself had made; and because our own iniquity had not in every part consumed His work, He knew at once both how, in each of us, to hate what we had done, and to love what He had done.
(Tr. cix) When our Lord had prayed for His disciples, whom He named also Apostles, He added a prayer for all others who should believe on Him; Neither pray I for these alone, but for all others who shall believe on Me through their word.
(Tr. cix) All, i. e. not only those who were then alive, but those who were to be born; not those only who heard the Apostles themselves, but us who were born long after their death. We have all believed in Christ through their word: for they first heard that word from Christ, and then preached it to others, and so it has come down, and will go down to all posterity. We may see that in this prayer there are some disciples whom He does not pray for; for those, i. e. who were neither with Him at the time, nor were about to believe on Him afterwards through the Apostles' word, but believed already. Was Nathanael with Him then, or Joseph of Arimathea, and many others, who, John says, believed on Him? I do not mention old Simeon, or Anna the prophetess, Zacharias, Elisabeth, or John the Baptist; for it might be answered that it was not necessary to pray for dead persons, such as these who departed with such rich merits. With respect to the former then we must understand that they did not yet believe in Him, as He wished, but that after His resurrection, when the Apostles were taught and strengthened by the Holy Spirit, they attained to a right faith. The case of Paul however still remains, An Apostle not of men, or by men; (Gal. 1:1) and that of the robber, who believed when even the teachers themselves of the faith fell away. We must understand then, their word, to mean the word of faith itself which they preached to the world; it being called their word, because it was preached in the first instance and principally by them; for it was being preached by them, when Paul received it by revelation from Jesus Christ Himself. And in this sense the robber too believed their word. Wherefore in this prayer the Redeemer prays for all whom He redeemed, both present and to come. And then follows the thing itself which He prays for, That they all may be one. He asks that for all, which he asked above for the disciples; that all both we and they may be one.
(Tr. cx) We must particularly observe here, that our Lord did not say, that we may be all one, but that they may be all one, as Thou, Father, in Me, and I in Thee, are one, understood. For the Father is so in the Son, that They are one, because They are of one substance; but we can be one in Them, but not with Them; because we and They are not of one substance. They are in us, and we in Them, so as that They are one in Their nature, we one in ours. They are in us, as God is in the temple; we in Them, as the creature is in its Creator. Wherefore He adds, in Us, to show, that our being made one by charity, is to be attributed to the grace of God, not to ourselves.
(iv. de. Trin. c. ix) Or that in ourselves we cannot be one, severed from each other by diverse pleasures, and lusts, and the pollution of sin, from which we must be cleansed by a Mediator, in order to be one in Him.
(Tr. cx) But why does He say, That the world may believe that Thou hast sent Me? Will the world believe when we shall all be one in the Father and the Son? Is not this unity that peace eternal, which is the reward of faith, rather than faith itself? For though in this life all of us who hold in the same common faith are one, yet even this unity is not a means to belief, but the consequence of it. What means then, That all may be one, that the world may believe? He prays for the world when He says, Neither pray I for these alone, but for all those who shall believe on Me through their word. Whereby it appears that He does not make this unity the cause of the world believing, but prays that the world may believe, as He prays that they all may be one. The meaning will be clearer if we always put in the word ask; I ask that they all may be one; I ask that they may be one in Us; I ask that the world may believe that Thou hast sent Me.
(Tr. cx) Then our Saviour, Who, by praying to the Father, showed Himself to be man, now shows that, being God with the Father, He doth what He prays for: And the glory which Thou gavest Me, I have given them. What glory, but immortality, which human nature was about to receive in Him? For that which was to be by unchangeable predestination, though future, He expresses by the past tense. That glory of immortality, which He says was given Him by the Father, we must understand He gave Himself also. For when the Son is silent of His own cooperation in the Father's work, He shows His humility: when He is silent of the Father's cooperation in His work, He shows His equality. In this way here He neither disconnects Himself with the Father's work, when He says, The glory which Thou gavest Me, nor the Father with His work, when He says, I have given them. But as He was pleased by prayer to the Father to obtain that all might be one, so now He is pleased to effect the same by His own gift; for He continues, That all may be one, even as We are one.
(Tr. cx. 4) Nor is this said, however, as if to mean that the Father was not in us, or we in the Father. He only means to say, that He is Mediator between God and man. And what He adds, That they may be made perfect in one, shows that the reconciliation made by this Mediator, was carried on even to the enjoyment of everlasting blessedness. So what follows, That the world may know that Thou hast sent Me, must not be taken to mean the same as the words just above, That the world may believe. For as long as we believe what we do not see, we are not yet made perfect, as we shall be when we have merited to see what we believe. So that when He speaks of their being made perfect, we are to understand such a knowledge as shall be by sight, not such as is by faith. These that believe are the world, not a permanent enemy, but changed from an enemy to a friend; as it follows: And hast loved them, as Thou hast loved Me. The Father loves us in the Son, because He elected us in Him. These words do not prove that we are equal to the Only Begotten Son; for this mode of expression, as one thing so another, does not always signify equality. It sometimes only means, because one thing, therefore another. And this is its meaning here: Thou hast loved them, as Thou hast loved Me, i. e. Thou hast loved them, because Thou hast loved Me. There is no reason for God loving His members, but that He loves him. But since He hateth nothing that He hath made, who can adequately express how much He loves the members of His Only Begotten Son, and still more the Only Begotten Himself.
He did not say, “I and they are one,” although inasmuch as he is the head of the church and the church is his body, he could not only say, “I and they are one but also one person,” because the head and the body are the one Christ. But when he reveals that his own Godhead is consubstantial with the Father (for which reason he also says in another place, “I and the Father are one”30), then it is rather his will that his own in their own kind, that is to say, in the consubstantial equality of the same nature, should be one, but be one in him. For they could not be one in themselves, since they were separated from one another by conflicting inclinations, desires and unclean sins. They are, therefore, purified through the Mediator, in order that they may be one in him. And indeed [they are one] not only through the same nature in which all mortals become equal to the angels, but also [they are one] by the same will working together most harmoniously toward the same blessedness, and [they are] fused together in some way by the fire of charity into one spirit.
And had He said, That they may know that Thou hast sent me, it would be just of the same force as what He actually does say, "that the world may know." For they are the world that abideth not in enmity, as doth the world that is foreordained to damnation; but one that out of an enemy has been transformed into a friend, and on whose account "God was in Christ reconciling the world unto Himself." Therefore said He, "I in them, and Thou in me;" as if He had said, I in those to whom Thou hast sent me; and Thou in me, reconciling the world unto Thyself through me.
In close relation to these come also His further words: "And Thou hast loved them as Thou hast loved me." That is to say, in the Son the Father loveth us, because in Him He hath chosen us before the foundation of the world. For He who loveth the Only-begotten, certainly loveth also His members which, through His instrumentality, He engrafted into Him by adoption. But we are not on this account equal to the only-begotten Son, by whom we have been created and re-created, that it is said, "Thou hast loved them as [Thou hast] also [loved] me." For one does not always intimate equality when he says, As this, so also that other; but sometimes only, Because this is, so also is the other; or, That the one is, in order that the other may be also. For who could say that the apostles were sent by Christ into the world in exactly the same way as He Himself was sent by the Father? For, to say nothing of other differences, which it would be tedious to mention, they at all events were sent when they were already men; but He was sent in order that He might be man; and yet He said above, "As Thou hast sent me into the world, even so have I sent them into the world;" as if He had said, Because Thou hast sent me, I have sent them. So also in the passage before us He says, "Thou hast loved them, as Thou hast loved me;" which is nothing else than this, Thou hast loved them because that Thou hast also loved me. For He could not but love the members of the Son, seeing that He loveth the Son Himself; nor is there any other reason for loving His members, save that He loveth Himself. But He loveth the Son as regards His Godhead, because He begat Him equal with Himself; He loveth Him also in regard to what He is as man, because the Only-begotten Word was Himself made flesh, and on account of the Word is the flesh of the Word dear to Him; but He loveth us, inasmuch as we are the members of Him whom He loveth; and in order that we might be so, He loved us on this account before we existed.
And then He added: "I in them, and Thou in me, that they may be made perfect in one." Here He briefly intimated Himself as the Mediator between God and men. Nor was this said in any such way as if the Father were not in us, or we were not in the Father; since He had also said in another place, "We will come unto him, and make our abode with him;" and a little before in this present passage He had not said, "I in them and Thou in me," as He said now; or, They in me, and I in Thee; but, "Thou in me, and I in Thee, and they in us." Accordingly, when He now says, "I in them, and Thou in me," the words take this form in reference to the person of the Mediator, like that other expression used by the apostle, "Ye are Christ's, and Christ is God's." But in adding, "That they may be made perfect in one," He showed that the reconciliation, which is effected by the Mediator, is carried to the very length of bringing us to the enjoyment of that perfect blessedness, which is thenceforth incapable of further addition. Hence the words that follow, "That the world may know that Thou hast sent me," are not, I think, to be taken as if He had again said, "That the world may believe;" for sometimes, to know, is also used in the same sense as to believe, as it is in the words He uttered some time before: "And they have known truly that I came out from Thee, and they have believed that Thou didst send me." He expressed the same thing by the later words, "they have believed," as He had done by the earlier, "they have known." But inasmuch as He here speaks of the consummation, the knowledge must be taken for such, as it shall then be by sight, and not, as it now is, by faith. For an order seems to have been preserved in reference to what He said a little before, "that the world may believe;" while here it is, "that the world may know." For although He said there, "that they all may be one," and "may be one in us," yet He did not say, "they may be made perfect in one," and so subjoined the words, "that the world may believe that Thou hast sent me;" but here He said, "That they may be made perfect in one," and then added, not, "that the world may believe," but, "that the world may know that Thou hast sent me." For so long as we believe what we do not see, we are not yet made perfect, as we shall be when we have merited the sight of that which we believe. Most correctly, therefore, did He say in that previous place, "That the world may believe," and here "That the world may know;" yet both there and here, "that Thou hast sent me;" that we may know, so far as belongs to the inseparable love of the Father and the Son, that at present we only believe what we are on the way, by believing, to know.
The Son dwells in us in a corporeal sense as man, commingled and united with us by the mystery of the Eucharist. And also [he dwells with us] in a spiritual sense as God, by the effectual working and grace of his own Spirit, building up our spirit into newness of life and making us partakers of his divine nature. Christ, then, is seen to be the bond of union between us and God the Father. He is seen as human, making us, as it were, his branches, and is seen as God because he is by nature inherent in his own Father. For in no other way could that nature which is subject to corruption be elevated to incorruption, except by the coming down to it of that nature that is high above all corruption and changeability.… We have, therefore, been made perfect in unity with God the Father, through the mediation of Christ. For by receiving in ourselves (both in a corporeal and spiritual sense, as I said just now) him who is the Son by nature and who has essential union with the Father, we have been glorified and become partakers in the nature of the Most High.
For we are made one with each other after the manner already indicated, and we are also made one with God. And in what sense we are made one with Him, the Lord very clearly explained, and to make the benefit of His teaching plain, added the words: I in them, and Thou in Me, that they may be made perfected into one. For the Son dwells in us in a corporeal sense as Man, commingled and united with us by the mystery of the Eucharist; and also in a spiritual sense as God, by the effectual working and grace of His own Spirit, building up our spirit into newness of life, and making us partakers of His Divine Nature. Christ, then, is seen to be the bond of union between us and God the Father; as Man making us, as it were, His branches, and as God by Nature inherent in His own Father. For no otherwise could that nature which is subject to corruption be uplifted into incorruption, but by the coming down to it of That Nature Which is high above all corruption and variableness, lightening the burthen of ever sinking humanity, so that it can attain its own good; and by drawing it into fellowship and intercourse with Itself, well-nigh extricating it from the limitations which suit the creature, and fashioning into conformity with Itself that which is of itself contrary to It. We have, therefore, been made perfect in unity with God the Father, through the mediation of Christ. For by receiving in ourselves, both in a corporeal and spiritual sense, as I said just now, Him that is the Son by Nature, and Who has essential union with the Father, we have been glorified and become partakers in the Nature of the Most High.
When Christ desires us to be admitted to union with God the Father, He at the same time calls down upon our nature this blessing from the Father, and also declares that the power which the grace confers will be a convincing refutation of those who think that He is not from God. For what ground will there be any longer for this false accusation, if of Himself He exalts to union with the Father those who have been brought near to Him through faith and sincere love? When, then, O Father, they gain union with Thee, through Me, then the world will know that Thou didst send Me; that is, that I came to succour the earth by Thy lovingkindness, and to work out the salvation of those who err therein. Besides, none the less, He says, will they know, who have partaken of a grace so acceptable, that Thou lovedst them, even as Thou lovedst Me. For surely He that received into union with Himself Him that is Man, even as we are, that is, Christ, and deemed Him worthy of so great love (we are arguing here concerning Christ as Man), and gave to us the chance of gaining this blessing, surely He would speak of His love as dealt out to us in equal measure. And let not any attentive hearer be perplexed hereby. For it is clear beyond dispute, that the servant can never vie with his master, and that the Father will not give as full a measure of His love to His creatures, as to His own Son. But we must consider that we are here looking upon Him That is beloved from everlasting, as commencing to be loved when He became Man. What, therefore, He then, as it were, took and received, we shall find that He took not for Himself, but for us. For just as, when He lived again after subduing the power of death, He accomplished not His Resurrection for Himself, for He is the Word and God, but gave us this blessing through Himself, and in Himself (for man's nature was in Christ in its entirety, fast bound by the chains of death); in like manner we must suppose that He received the Father's love, not for Himself, because He was continually beloved of Him from the beginning, but rather He accepts it at His Hands upon His Incarnation, that He may call down upon us the Father's love. Just as, then, we shall be, nay, we are even now, as in Christ first the Firstfruits of our race, made conformable to His Resurrection and His glory, even so are we, as it were, like Him; beloved, but yielding the supremacy in all things to the Only-begotten, and justly marvelling at the incomparable mercy of God, shown towards us; Who showers, as it were, upon us the things that are His, and shares with His creatures what appertains to Himself alone.
[Responding to the question "Many people are quite unable to understand the theological differences which have caused divisions in the Christian Church. Do you consider that these differences are fundamental, and is the time now ripe for reunion?"]
The time is always ripe for reunion. Divisions between Christians are a sin and a scandal, and Christians ought at all times to be making contributions toward reunion, if it is only by their prayers. I am only a layman and a recent Christian, and I do not know much about these things, but in all the things which I have written and thought I have always stuck to traditional, dogmatic positions. The result is that letters of agreement reach me from what are ordinarily regarded as the most different kinds of Christians; for instance, I get letters from Jesuits, monks, nuns, and also from Quakers and Welsh Dissenters, and so on. So it seems to me that the "extremist" elements in every church are nearest one another and the liberal and "broad-minded" people in each body could never be united at all. The world of dogmatic Christianity is a place in which thousands of people of quite different types keep on saying the same thing, and the world of "broad-mindedness" and watered-down "religion" is a world where a small number of people (all of the same type) say totally different things and change their minds every few minutes. We shall never get reunion from them.

SUMMARY
John 17:23, a pivotal verse from Jesus' High Priestly Prayer, articulates the profound spiritual unity believers are called to share, mirroring the perfect oneness between the Father and the Son. This divine indwelling and collective maturity serve a dual purpose: to validate Jesus' divine mission to the world and to reveal the Father's boundless love for His people, a love as deep and unwavering as His love for the Son Himself. The verse underscores the missional impact of authentic Christian unity and the astonishing depth of God's affection for humanity.
CONTEXT
Literary Context: This verse is nestled within Jesus' deeply intimate and intercessory prayer to His Father, recorded in John 17. Offered in the Upper Room just hours before His betrayal and crucifixion, this prayer moves sequentially from Jesus' prayer for Himself (John 17:1-5), to His prayer for His immediate disciples (John 17:6-19), and culminates in His prayer for all future believers (John 17:20-26). Verse 23 specifically expands upon the theme of unity introduced in John 17:21-22, reiterating the desire for believers to be "one" and emphasizing the ultimate purpose of this unity as a powerful witness to the world. It is the climax of Jesus' intercession for the global church.
Historical & Cultural Context: The setting is the Passover week in Jerusalem, a time of immense spiritual and political tension. Jesus and His disciples have just shared the Last Supper, instituting the new covenant meal. The disciples are grappling with the impending departure of their Lord and the uncertainty of their future. In a culture where unity often stemmed from shared ethnicity, family, or religious tradition, Jesus' prayer for a spiritual unity transcending these boundaries would have been revolutionary. The concept of "knowing" (ginōskō) in this context often implied a deep, relational understanding, not merely intellectual assent, which was crucial for both internal cohesion and external witness in a diverse Roman-occupied world. The emphasis on being "sent" (apostéllō) by God carried significant weight, signifying divine authority and a specific mission, understood within the Jewish prophetic tradition.
Key Themes: John 17 is rich with interconnected themes, and verse 23 contributes significantly to several. The overarching theme is Unity, specifically the unity of believers reflecting the Trinitarian unity of the Father and the Son. This unity is not merely organizational but a profound spiritual indwelling, as expressed by "I in them, and thou in me." Another crucial theme is Divine Love, highlighted by the staggering statement "hast loved them, as thou hast loved me," which elevates the believer's standing in God's affection to an incomprehensible level. This love is the foundation of their unity and the driving force of their mission. Finally, the theme of Witness and Mission is paramount, as the ultimate purpose of this perfected unity and divine love is "that the world may know that thou hast sent me." This underscores the evangelistic imperative inherent in the church's very existence, demonstrating that Christian unity is not an end in itself, but a powerful apologetic for the truth of Christ's identity and mission, echoing the broader missional thrust found in passages like John 3:16-17.
EXPOSITION AND ANALYSIS
Key Word Analysis
Verse Breakdown
Literary Devices
John 17:23 masterfully employs several literary devices to convey its profound message. Parallelism is evident in the symmetrical structure of "I in them, and thou in me," which highlights the reciprocal nature of the divine indwelling and sets the stage for the mirroring of Trinitarian unity in believers. The Repetition of the concept of "love" ("hast loved them, as thou hast loved me") emphasizes the staggering and foundational nature of God's affection, drawing a direct and astonishing comparison between the Father's love for the Son and His love for believers. Furthermore, the entire verse functions as a powerful example of Purpose Clause Construction, using "that" (Greek: hina) twice to clearly delineate the two primary outcomes of unity: internal perfection and external witness. The concept of "one" (Greek: hen) serves as potent Symbolism, representing not merely numerical singularity but a profound, spiritual, and relational unity that reflects the very essence of the Godhead.
THEOLOGICAL AND THEMATIC CONNECTIONS
John 17:23 stands as a cornerstone for understanding the nature of the church, the character of God, and the missional imperative of believers. It reveals that the ultimate purpose of the church's existence is not merely internal fellowship but external witness. The unity Jesus prays for is not a superficial agreement but a profound, spiritual oneness rooted in the indwelling presence of Christ, mirroring the Trinitarian unity. This unity, perfected in love, becomes the most compelling apologetic for the truth of the gospel, demonstrating to a fragmented world the reality of God's transformative power and His boundless love. It challenges believers to pursue genuine spiritual maturity and harmonious relationships, recognizing that their collective witness is inextricably linked to the credibility of their message.
REFLECTION AND APPLICATION
John 17:23 calls us to a radical re-evaluation of our priorities as followers of Christ. If Jesus' deepest desire for us, just hours before His ultimate sacrifice, was our unity and its impact on the world, then our pursuit of unity must be more than a preference; it is a spiritual imperative. This unity is not achieved through human effort alone but flows from the divine indwelling—Christ in us, and the Father in Him. It means laying down our personal preferences, denominational distinctives, and even our perceived "rights" for the sake of a greater good: the visible demonstration of God's love and the validation of Christ's mission. When the world sees Christians, despite their diverse backgrounds, united in genuine love and purpose, it encounters a living testament to the transforming power of the Gospel. This verse challenges us to actively cultivate relationships marked by humility, forgiveness, and mutual submission, allowing the Spirit to "perfect" us in this oneness, so that our collective life becomes a beacon that draws others to the Father's astonishing love.
Questions for Reflection
FAQ
What does "made perfect in one" truly mean in John 17:23?
Answer: "Made perfect in one" (Greek: teleioō eis hen) signifies a process of being brought to spiritual maturity, completion, and ultimate fulfillment in unity. It's not about losing individual identity but about achieving a profound spiritual harmony and oneness of purpose, mind, and spirit among believers. This unity reflects the perfect, seamless unity within the Trinity—Father, Son, and Holy Spirit. It implies that as believers grow in Christ, they increasingly embody the unified nature of God, demonstrating a collective wholeness that is both spiritually profound and visibly compelling. This perfection is a dynamic process, not a static state, continually being worked out by the Holy Spirit in the lives of believers.
How does the unity of believers serve as a witness to the world?
Answer: The unity of believers acts as a powerful witness to the world by demonstrating the supernatural reality and transformative power of God. In a world often characterized by division, conflict, and self-interest, a community of diverse individuals united by a common love for Christ and for one another stands out as a tangible manifestation of God's presence. As John 13:35 states, "By this shall all men know that ye are my disciples, if ye have love one to another." When the world observes Christians living in harmony, forgiving one another, and working together despite differences, it sees a compelling apologetic for the truth of the Gospel. This visible unity validates Jesus' claim that the Father sent Him and that the Father loves humanity with an astonishing love, drawing people to inquire about the source of such a profound connection.
CHRIST-CENTERED FULFILLMENT
John 17:23 finds its ultimate fulfillment in Christ's redemptive work, which establishes the very possibility of this profound unity and unparalleled love. Jesus' incarnation, obedient life, atoning death, and glorious resurrection are the means by which believers are brought into the divine life and made "perfect in one." Through His sacrifice, the barriers of sin and separation are removed, allowing for the indwelling of the Holy Spirit, who then enables believers to live in unity with Christ and with one another, as promised in Ephesians 2:14-16. The Father's love for believers, equated with His love for the Son, is a direct result of their being "in Christ," adopted into God's family through His Son (Romans 8:15-17). Thus, the unity and love described in John 17:23 are not merely aspirational but are the fruit of Christ's accomplished work on the cross, making us new creations who can genuinely reflect the Trinitarian unity and bear witness to the world of God's sending of His Son (2 Corinthians 5:17-19).
