AUGUSTINE . (Tr. cviii) They had not yet experienced these sufferings which they afterwards met with; but, after His custom, He puts the future into the past tense. Then He gives the reason why the world haled them; viz. Because they are not of the world. This was conferred upon them by regeneration; for by nature they were of the world. It was given to them that they should not be of the world, even as He was not of the world; as it follows; Even as I am not of the world. He never was of the world; for even His birth of the form of a servant He received from the Holy Ghost, from Whom they were born again. But though they were no longer of the world, it was still necessary that they should be in the world: I pray not that Thou shouldest take them out of the world.
BEDE . As if to say, The time is now at hand, when I shall be taken out of the world; and therefore it is necessary that they should be still left in the world, in order to preach Me and Thee to the world. But that Thou shouldest keep them from the evil; every evil, but especially the evil of schism.
AUGUSTINE . (Tr. cviii) He repeats the same thing again; They are not of the world, even as I am not of the world.
CHRYSOSTOM . (Hom. lxxxii. 1) Above, when He said, Them whom Thou gavest Me out of the world, He meant their nature; here He means their actions. They are not of the world; because they have nothing in common with earth, they are made citizens of heaven. Wherein He shews His love for them, thus praising them to the Father. The word as when used with respect to Him and the Father expresses likeness of nature; but between us and Christ there is immense distance. Keep them from the evil, i. e. not from dangers only, but from falling away from the faith.
AUGUSTINE . (Tr. cviii) Sanctify them through Thy truth: for thus were they to be kept from the evil. But it may be asked, how it was that they were not of the world, when they were not yet sanctified in the truth? Because the sanctified have still to grow in sanctity, and this by the help of God’s grace. The heirs of the New Testament are sanctified in that truth, the shadows of which were the sanctification of the Old Testament; they are sanctified in Christ, Who said above, I am the way, the truth, and the life. (c. 14:6) It follows, Thy discourse is truth. The Greek is λόγος, i. e. word. The Father then sanctified them in the truth, i. e. in His Word the Only-Begotten, them, i. e. the heirs of God, and joint-heirs with Christ.
CHRYSOSTOM . (Hom. lxxxii) Or thus: Sanctify them in Thy truth; i. e. Make them holy, by the gift of the Holy Spirit, and sound doctrines: for sound doctrines give knowledge of God, and sanctify the soul. And as He is speaking of doctrines, He adds, Thy word is truth, i. e. there is in it no lie, nor any thing typical, or bodily. Again, Sanctify them in Thy truth, may mean, Separate them for the ministry of the word, and preaching.
GLOSS . As Thou hast sent Me into the world, even so have I also sent them into the world. For what Christ was sent into the world, for the same end were they; as saith Paul, God was in Christ reconciling the world unto Himself; and hath given to us the word of reconciliation. (2 cor. 5:19) As does not express perfect likeness between our Lord and His Apostles, but only as much as was possible in men. Have sent them, He says, according to His custom of putting the past for the future.
AUGUSTINE . (Tr. cviii) It is manifest by this, that He is still speaking of the Apostles; for the very word Apostle means in the Greek, sent. But since they are His members, in that He is the Head of the Church, He says, And for their sakes I sanctify Myself; i. e. I in Myself sanctify them, since they are Myself. And to make it more clear that this was His meaning, He adds, That they also might be sanctified through the truth, i. e. in Me; inasmuch as the Word is truth, in which the Son of man was sanctified from the time that the Word was made flesh. For then He sanctified Himself in Himself, i. e. Himself as man, in Himself as the Word: the Word and man being one Christ. But of His members it is that He saith, And for their sakes I sanctify Myself, i. e. them in Me, since in Me both they and I are. That they also might be sanctified in truth: they also, i. e. even as Myself; and in the truth, i. e. Myself.
CHRYSOSTOM . (Hom. lxxxii) Or thus: For their sakes I sanctify Myself, i. e. I offer Myself as a sacrifice to Thee; for all sacrifices, and things that are offered to God, are called holy. And whereas this sanctification was of old in figure, (a sheep being the sacrifice,) but now in truth, He adds, That they also might be sanctified through the truth; i. e. For I make them too an oblation to Thee; either meaning that He who was offered up was their head, or that they would be offered up too: as the Apostle saith, Present your bodies a living sacrifice, holy. (Rom. 12:1)
17:20–23
20. Neither pray I for these alone, but for them also which shall believe on me through their word;
21. 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 may believe that thou hast sent me.
22. And the glory which thou gavest me I have given them; that they may be one, even as we are one:
23. I in them, and thou in me, that they may be made perfect in one: and that the world may know that thou hast sent me, and hast loved them, as thou hast loved me.
AUGUSTINE . (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.
CHRYSOSTOM . (Hom. lxxxii) Another ground of consolation to them, that they were to be the cause of the salvation of others.
AUGUSTINE . (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.
CHRYSOSTOM . (Hom. lxxxii) And with this prayer for unanimity, He concludes His prayer; and then begins a discourse on the same subject: A new commandment I give unto you, that ye love one another.
HILARY . (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.
CHRYSOSTOM . (Hom. lxxxii) This as again does not express perfect likeness, but only likeness as far as it was possible in men; as when He saith, Be ye merciful, even as your Father, which is in heaven, is merciful. (Luke 6:36)
AUGUSTINE . (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 shew, that our being made one by charity, is to be attributed to the grace of God, not to ourselves.
AUGUSTINE . (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.
HILARY . (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 meaning1 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.
AUGUSTINE . (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.
HILARY . (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.
