John 17:21

(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.

They quote the prayer of our Lord for the salvation of the nations who should believe in Him: "Neither for these only do I pray, but for them also that shall believe on Me through their Word; that they all may be one; even as Thou, Father, art in Me, and I in Thee, that they also may be in Us," to shew that since men cannot, so to speak, be fused back into God or themselves coalesce into one undistinguished mass, this oneness must arise from unity of will, while all perform actions pleasing to God, and unite one with another in the harmonious accord of their thoughts, and that thus it is not nature which makes them one, but will.

(vii de Trin) And this unity is recommended by the great example of unity: As Thou, Father, art in Me, and I in Thee, that they also may be one in Us, i. e. that as the Father is in the Son, and the Son in the Father, so, after the likeness of this unity, all may be one in the Father and in the Son. (viii. de Trin) Heretics endeavouring to get over the words, I and My Father are one, as a proving unity of nature, and to reduce them to mean a unity simply of natural love, and agreement of will, bring forwards these words of our Lord's as an example of this kind of unity: That they may be all one, as Thou, Father, art in Me, and I in Thee. But though impiety can cheat its own understanding, it cannot alter the meaning of the words themselves. For they who are born again of a nature that gives unity in life eternal, they cease to be one in will merely, acquiring the same nature by their regeneration: but the Father and Son alone are properly one, because God, only-begotten of God, can only exist in that nature from which He is derived. (viii. de Trin) Or, the world will believe that the Son is sent from the Father, for that reason, viz. because all who believe in Him are one in the Father and the Son.

Our Lord Jesus Christ, then, prays not for the twelve Apostles alone, but rather for all who were destined in every age to yield to and obey the words that exhort those who hear to receive that sanctification that is through faith, and to that purification which is accomplished in them through partaking of the Spirit.… What, then, is the manner of His prayer? *That,* He says, *they may be one; even as Thou, Father, art in Me, and I in Thee, that they also may be one in Us.* He asks, then, for a bond of love, and concord, and peace, to bring into spiritual unity those who believe; so that their unitedness, through perfect sympathy and inseparable harmony of soul, might resemble the features of the natural and essential unity that exists between the Father and the Son.… The Only-begotten, then, proceeding from the very Substance of God the Father, and having entirely in His own Nature Him That begat Him, became Flesh according to the Scripture, blending Himself, as it were, with our nature by an unspeakable combination and union with this body that is earthy; and thus He That is God by Nature became, and is in truth, a Man from heaven… in order that, uniting as it were in Himself things widely opposed by nature, and averse to fusion with each other, He might enable man to share and partake of the Nature of God. For even unto us has reached the fellowship and abiding Presence of the Spirit, which originated through Christ and in Christ first, when He is in fact become even as we are, that is, a Man, receiving unction and sanctification, though He is by Nature God, insomuch as He proceeded from the Father Himself, sanctifying with His own Spirit the temple of His Body as well as all the creation that to Him owes its being, and to which sanctification is suitable.

But let these things which were done by Stephen be passed by for the present, lest, while we remember his audacity and pride, we bring a more lasting sadness on ourselves from the things that he has wickedly done. And knowing, concerning you, that you have settled this matter, concerning which there is now a question, according to the rule of truth and the wisdom of Christ; we have exulted with great joy, and have given God thanks that we have found in brethren placed at such a distance such a unanimity of faith and truth with us. For the grace of God is mighty to associate and join together in the bond of charity and unity even those things which seem to be divided by a considerable space of earth, according to the way in which of old also the divine power associated in the bond of unanimity Ezekiel and Daniel, though later in their age, and separated from them by a long space of time, to Job and Noah, who were among the first; so that although they were separated by long periods, yet by divine inspiration they felt the same truths. And this also we now observe in you, that you who are separated from us by the most extensive regions, approve yourselves to be, nevertheless, joined with us in mind and spirit. All which arises from the divine unity. For even as the Lord who dwells in us is one and the same, He everywhere joins and couples His own people in the bond of unity, whence their sound has gone out into the whole earth, who are sent by the Lord swiftly running in the spirit of unity; as, on the other hand, it is of no advantage that some are very near and joined together bodily, if in spirit and mind they differ, since souls cannot at all be united which divide themselves from God's unity.

After having thus spoken concerning their salvation, and their being sanctified by faith and the Sacrifice, He afterwards speaketh of concord, and finally closeth his discourse with this, having begun with it and ended in it. For at the beginning He saith, "A new commandment I give unto you"; and here, "That they all may be one, as Thou, Father, art in Me and I in Thee." Here again the "as" doth not denote exact similarity in their case, (for it was not possible for them in so great a degree,) but only as far as was possible for men. Just as when He saith "Be ye merciful, as your Father."

But what is, "In Us"? In the faith which is on Us. Because nothing so offends all men as divisions, He provideth that they should be one. "What then," saith some one, "did He effect this?" Certainly He effected it. For all who believe through the Apostles are one, though some from among them were torn away. Nor did this escape His knowledge, He even foretold it, and showed that it proceeded from men's slack-mindedness. "That the world may believe that Thou hast sent Me." As He said in the beginning, "By this shall all men know that ye are My disciples, if ye love one another," And how should they hence believe? "Because," He saith, "Thou art a God of peace." If therefore they observe the same as those of whom they have learnt, their hearers shall know the teacher by the disciples, but if they quarrel, men shall deny that they are the disciples of a God of peace, and will not allow that I, not being peaceable, have been sent from Thee. Seest thou how, unto the end, He proveth His unanimity with the Father?

Elsewhere He says of Himself and the Father, We will come and make Our abode with Him; by the mention of two persons, stopping the mouths of the Sabellians. Here by saying that the Father comes to the disciples through Him, He refutes the notion of the Arians.

"As we are Father, Son and Holy Spirit, one God," [Jesus might say], "so may they be one people in themselves, that is, like dear children and partakers of the divine nature." Call the church what you will—bride, sister, mother—its assembly is but one and never lacks husband, brother or son. [The church's] faith is one, and it is not defiled by variety of doctrine or divided by heresies. [The church] continues a virgin. Wherever the Lamb goes, it follows him. It alone knows the song of Christ.

But that God is good, all willingly admit; and that the same God is just, I require not many more words to prove, after adducing the evangelical utterance of the Lord; He speaks of Him as one, "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." God is one, and beyond the one and above the Monad itself.

And since He has sufficiently committed them to the Father, that He might sanctify them by faith and offered the holy sacrifice for them for the truth, He speaks, finally, again about unity of mind, and with what He began, that is, with love, with …

That they may be one, through conformity of love, as you, Father, are in me, and I in you, that is, as we are one, that they also may be one in us; Galatians 3: "You are all one in Christ Jesus." This unity is …

He prays for a perfect unity when he says, that they may all be one. First, he mentions the unity he is asking for; secondly, he gives an example of it, and its cause, as you, Father, are in me; thirdly, he gives the fruit …

As thou art in me - This also is to be understood in a way of similitude, and not of sameness or equality. That the world may believe - Here Christ prays for the world. Observe the sum of his whole prayer, 1.

That they all may be one,.... Among themselves.

While there is life, there is hope, and room for prayer. Whom he did pray for; not for angels, but for the children of men. He prays for those that were given him, meaning primarily the disciples that had attended him in this regeneration; but it is doubtless to be extended further, to all who come under the same character, who receive and believe the words of Christ,

That they all may be one - This prayer was literally answered to the first believers, who were all of one heart and of one soul: Act 4:32. And why is it that believers are not in the same spirit now? Because they neither attend to the example nor to the truth of Christ. That the world may believe - are have already seen that the word, κοσμος, world, is used in several parts of this last discourse of our Lord to signify the Jewish people only.

These wonderful verses form a fitting conclusion of the most wonderful prayer that was ever prayed on earth —the last Lord's prayer after the first Lord's Supper. They contain three most important petitions which our Lord offered up in behalf of His disciples. On these three petitions let us fix our attention. Passing by all other things in the passage, let us look steadily at these three points. We should mark, first, how Jesus prays that His people may be sanctified. "Sanctify them," He says, "through your truth—Your word is truth."

But the Spirit of Christ, illuminating, transforming, and reigning in the hearts of the genuine disciples of Christ, drawing them to each other as members of one family, and prompting them to loving co-operation for the good of the world--this is what, when sufficiently glowing and extended, shall force conviction upon the world that Christianity is divine.

Neither pray I for these alone--This very important explanation, uttered in condescension to the hearers and readers of this prayer in all time, is meant not merely of what follows, but of the whole prayer. them also which shall believe--The majority of the best manuscripts read "which believe," all future time being viewed as present, while the present is viewed as past and gone.

Passing by all other things in the passage, let us look steadily at these three points. We should mark, first, how Jesus prays that His people may be sanctified. "Sanctify them," He says, "through your truth—Your word is truth." We need not doubt that, in this place at any rate, the word "sanctify" means "make holy." It is a prayer that the Father would make His people more holy, more spiritual, more pure, more saintly in thought and word and deed, in life and character. Grace had done something for the disciples already—called, converted, renewed, and changed them. The great Head of the Church prays that the work of grace may be carried higher and further, and that His people may be more thoroughly sanctified and made holy in body, soul, and spirit—in fact more like Himself. Surely we need not say much to show the matchless wisdom of this prayer. More holiness is the very thing to be desired for all servants of Christ. Holy living is the great proof of the reality of Christianity. Men may refuse to see the truth of our arguments, but they cannot evade the evidence of a godly life. Such a life adorns religion and makes it beautiful, and sometimes wins those who are not "won by the Word." Holy living trains Christians for heaven. The nearer we live to God while we live, the more ready shall we be to dwell forever in His presence when we die. Our entrance into heaven will be entirely by grace, and not of works; but heaven itself would be no heaven to us if we entered it with an unsanctified character. Our hearts must be in tune for heaven if we are to enjoy it.

FOR several years I have thankfully received the text of the first Sabbath in the year from a venerable clergyman of a parish in the suburbs of our city. Spared by a gracious Providence, my good Brother has sent me, with his Christian salutations, these two verses for my subject.

FOR several years I have thankfully received the text of the first Sabbath in the year from a venerable clergyman of a parish in the suburbs of our city. Spared by a gracious Providence, my good Brother has sent me, with his Christian salutations, these two verses for my subject. As we have enjoyed together for several years a true communion of spirit in the things of God, I can only hope, that until one or the other of us shall be taken up to dwell above, we may walk together in holy service, loving each other fervently with a pure heart. The most tender and touching prayer of the Master contained in this chapter opens up to us His inmost heart. He was in Gethsemane and His passion was just commencing. He stood like a victim at the altar where the wood was already laid in order and the fire was kindled to consume the sacrifice. Lifting up His eyes to Heaven, with true filial love gazing upon His Father's Throne, and resting in humble confidence upon Heaven's strength, He looked away for a moment from the strife and resistance unto blood which was going on below. He asked for that upon which His heart was most fully set. He opened His mouth wide that His God might fill it. This prayer, I take it, was not only the casual expression of the Savior's desire at the last, but is a sort of model of the prayer which is incessantly going up from Him to the Eternal Throne. There is a difference in the mode of its offering. With sighs and tears He offered up His humble suit below—but with authority He now pleads enthroned in Glory! But the plea is the same—that which He desired while still below is that which His soul pants after now that He is taken up and is glorified above.
