Catena Aurea by St. Thomas Aguinas
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.
CHRYSOSTOM. (Hom. lxxxii) For there is no scandal so great as division, whereas unity amongst believers is a great argument for believing; as He said at the beginning of His discourse, By this shall all men know that ye are My disciples, if ye have love one to another. For if they quarrel, they will not be looked on as the disciples of a peacemaking Master. And I, He saith, not being a peacemaker, they will not acknowledge Me as sent from God.
AUGUSTINE. (Tr. cx) Then our Saviour, Who, by praying to the Father, shewed Himself to be man, now shews 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 shews His humility: when He is silent of the Father’s cooperation in His work, He shews 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.
CHRYSOSTOM. (Hom. lxxxii. 2) By glory, He means miracles, and doctrines, and unity; which latter is the greater glory. For all who believed through the Apostles are one. If any separated, it was owing to men’s own carelessness; not but that our Lord anticipates this happening.
HILARY. (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.
CHRYSOSTOM. (Hom. lxxxii) Elsewhere1 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.
AUGUSTINE. (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, shews 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.
17:24–26
24. Father, I will that they also, whom thou hast given me, be with me where I am; that they may behold my glory, which thou hast given me: for thou lovedst me before the foundation of the world.
25. O righteous Father, the world hath not known thee: but I have known thee, and these have known that thou hast sent me.
26. And I have declared unto them thy name, and will declare it: that the love wherewith thou hast loved me may be in them, and I in them.
CHRYSOSTOM. (Hom. lxxxii. 2) After He has said that many should believe on Him through them, and that they should obtain great glory, He then speaks of the crowns in store for them; Father, I will that they also whom Thou hast given Me, be with Me where I am.
AUGUSTINE. (Tr. cxi. 1) These are they whom He has received from the Father, whom He also chose out of the world; as He saith at the beginning of this prayer, Thou hast given Him power over all flesh, i. e. all mankind, That He should give eternal life to as many as Thou hast given Him. Wherein He shews that He had received power over all men, to deliver whom He would, and to condemn whom He would. Wherefore it is to all His members that He promises this reward, that where He is, they may be also. Nor can that but be done, which the Almighty Son saith that He wishes to the Almighty Father: for the Father and the Son have one will, which, if weakness prevent us from comprehending, piety must believe. Where I am: so far as pertains to the creature, He was made of the seed of David according to the flesh: He might say, Where I am, meaning where He was shortly to be, i. e. heaven. In heaven then, He promises us, we shall be. For thither was the form of a servant raised, which He had taken from the Virgin, and there placed on the right hand of God.
GREGORY. (Moral.) What means then what the Truth saith above, No man hath ascended into heaven, but He that came down from heaven, even the Son of man which is in heaven. (John 3:13) Yet here is no discrepancy, for our Lord being the Head of His members, the reprobates excluded, He is alone with us. And therefore, we making one with Him, whence He came alone in Himself, thither He returns alone in us.
AUGUSTINE. (Tr. cxi) But as respects the form of God, wherein He is equal to the Father, if we understand these words, that they may be with Me where I am, with reference to that, then away with all bodily ideas, and enquire not where the Son, Who is equal to the Father, is: for no one hath discovered where He is not. Wherefore it was not enough for Him to say, I will that they may be where I am, but He adds, with Me. For to be with Him is the great good: even the miserable can be where He is, but only the happy can be with Him. And as in the ease of the visible, though very different be whatever example we take, a blind man will serve for one, as a blind man though He is where the light is, yet is not himself with the light, but is absent from it in its presence, so not only the unbelieving, but the believing, though they cannot be where Christ is not, yet are not themselves with Christ by sight: by faith we cannot doubt but that a believer is with Christ. But here He is speaking of that sight wherein we shall see Him as He is; as He adds, That they may behold My glory, which Thou hast given Me. That they may behold, He says, not, that they may believe. It is the reward of faith which He speaks of, not faith itself.
CHRYSOSTOM. (Hom. lxxxii) He saith not, that they may partake of My glory, but, that they may behold, intimating that the rest there is to see the Son of God. The Father gave Him glory, when He begat Him.
AUGUSTINE. (Tr. cxi. 3) When then we shall have seen the glory which the Father gave the Son, though by this glory we do not understand here, that which He gave to the equal Son when He begat Him, but that which He gave to the Son of man, after His crucifixion; then shall the judgment be, then shall the wicked be taken away, that he see not the glory of the Lord: what glory but that whereby He is God? If then we take their words, That they may be with Me where I am, to be spoken by Him as Son of God, in that case they must have a higher meaning, viz. that we shall be in the Father with Christ. As He immediately adds, That they may see My glory which Thou hast given Me; and then, Which Thou gavest Me before the foundation of the world. For in Him He loved us before the foundation of the world, and then predestined what He should do at the end of the world.
BEDE. That which He calls glory then is the love wherewith He was loved with the Father before the foundation of the world. And in that glory He loved us too before the foundation of the world.
THEOPHYLACT. After then that He had prayed for believers, and promised them so many good things, another prayer follows worthy of His mercy and benignity: O righteous Father, the world hath not known Thee; as if to say, I would wish that all men obtained these good things, which I have asked for the believing. But inasmuch as they have not known Thee, they shall not obtain the glory and crown.
CHRYSOSTOM. (Hom. lxxxii) He says this as if He were troubled at the thought, that they should be unwilling to know One so just and good. And whereas the Jews had said, that they knew God, and He knew Him not: He on the contrary says, But I have known Thee, and these have known that Thou hast sent Me, and I have declared unto them Thy name, and will declare1 it, by giving them perfect knowledge through the Holy Ghost. When they have learned what Thou art, they will know that I am not separate from Thee, but Thine own Son greatly beloved, and joined to Thee. This I have told them, that I might receive them, and that they who believe this aright, shall preserve their faith and love toward Me entire; and I will abide in them: That the love wherewith Thou hast loved Me may be in them, and I in them.
AUGUSTINE. (Tr. cxi. 5) Or thus; What is to know Him, but eternal life, which He gave not to a condemned but to a reconciled world? For this reason the world hath not known Thee; because Thou art just, and hast punished them with this ignorance of Thee, in reward for their misdeeds. And for this reason the reconciled world knows Thee, because Thou art merciful, and hast vouchsafed this knowledge, not in consequence of their merits, but of thy grace. It follows: But I have known Thee. He is God the fountain of grace by nature, man of the Holy Ghost and Virgin by grace ineffable. Then because the grace of God is through Jesus Christ, He says, And they have known Me, i. e. the reconciled world have known Me, by grace, forasmuch as Thou hast sent Me. And I have made known Thy name to them by faith, and will make it known by sight: that the love wherewith Thou hast loved Me may be in them. (2 Tim. 4:7) The Apostle uses a like phrase, I have fought a good fight, by a good fight being the more common form. The love wherewith the Father loveth the Son in us, can only be in us because we are His members, and we are loved in Him when He is loved wholly, i. e. both head and body. And therefore He adds, And I in them; He is in us, as in His temple, we in Him as our Head.
Catena Aurea John 17
From: John 17:20-26The Priestly Prayer of Jesus (Continuation)
-------------------------------------------
(Jesus lifted His eyes to Heaven and said,) [20] "I do not pray for these (My disciples) only, but also for those who believe in Me through their word, [21] that they may all be one; even as Thou, Father, art in Me, and I in Thee, that they also may be in us, so that the world may believe that Thou hast sent Me. [22] The glory which Thou hast given Me I have given to them, that they may be one even as we are one, [23] I in them and Thou in Me, that they may become perfectly one, so that the world may know that Thou hast sent Me and hast loved them even as Thou hast loved Me. [24] Father, I desire that they also, whom Thou hast given Me, may be with Me where I am, to behold My glory which Thou hast given Me in Thy love for Me before the foundation of the world. [25] O righteous Father, the world has not known Thee, but I have known Thee; and these know that Thou hast sent Me. [26] I made known to them Thy name, and I will make it known, that the love with which Thou hast loved Me may be in them, and I in them."
***********************************************************************
Commentary:
20-23. Since it is Christ who is praying for the Church His prayer is infallibly effective, and therefore there will always be only one true Church of Jesus Christ. Unity is therefore an essential property of the Church. "We believe that the Church founded by Jesus Christ and for which He prayed is indefectibly one in faith, in worship and in the bond of hierarchical communion" (St Paul VI, "Creed of the People of God", 21). Moreover, Christ's prayer also indicates what the basis of the Church's unity will be and what effects will follow from it.
The source from which the unity of the Church flows is the intimate unity of the Three Divine Persons among whom there is mutual love and self-giving. "The Lord Jesus, when praying to the Father `that they may all be one...even as we are one' (John 17:21-22), has opened up new horizons closed to human reason by implying that there is a certain parallel between the union existing among the Divine Persons and the union of the sons of God in truth and love. It follows, then, that if man is the only creature on earth that God has wanted for its own sake, man can fully discover his true self only in a sincere giving of himself" (Vatican II, "Gaudium Et Spes", 24). The unity of the Church is also grounded on the union of the faithful with Jesus Christ and through Him with the Father (verse 23). Thus, the fullness of unity--"consummati in unum"--is attained through the supernatural grace which comes to us from Christ (cf. John 15:5).
The fruits of the unity of the Church are, on the one hand, the world believing in Christ and in His divine mission (verses 21, 23); and, on the other hand, Christians themselves and all men recognizing God's special love for His faithful, a love which is a reflection of the love of the Three Divine Persons for each other. And so, Jesus' prayer embraces all mankind, for all are invited to be friends of God (cf. 1 Timothy 2:4). "Thou hast loved them even as Thou hast loved Me": this, according to St. Thomas Aquinas, "does not mean strict equality of love but similarity and like-motivation. It is as if He were saying: the love with which You have loved Me is the reason and the cause of Your loving them, for, precisely because You love men do You love those who love Me" ("Commentary on St. John, in loc."). Besides noting this theological explanation, we should also ponder on how expressively Christ describes His ardent love for men. The entire discourse of the Last Supper gives us a glimpse of the depth of Jesus' feelings—which infinitely exceeds anything we are capable of experiencing. Once again all we can do is bow down before the mystery of God-made-man.
20. Christ prays for the Church, for all those who, over the course of centuries, will believe in Him through the preaching of the Apostles. "That divine mission, which was committed by Christ to the Apostles, is destined to last until the end of the world (cf. Matthew 28:20), since the Gospel, which they were charged to hand on, is, for the Church, the principle of all its life for all time. For that very reason the Apostles were careful to appoint successors in this hierarchically constituted society" (Vatican II, "Lumen Gentium", 20).
The apostolic origin and basis of the Church is what is termed its "apostolicity", a special characteristic of the Church which we confess in the Creed. Apostolicity consists in the Pope and the Bishops being successors of Peter and the Apostles, holding the authority of the Apostles and proclaiming the same teaching as they did. "The sacred synod teached that the bishops have by divine institution taken the place of the Apostles as pastors of the Church, in such wise that whoever listens to them is listening to Christ and whoever despises them despises Christ and Him who sent Christ (cf. Luke 10:15)" (Vatican II, "Lumen Gentium", 20).
21. Union of Christians with Christ begets unity among themselves. This unity of the Church ultimately redounds to the benefit of all mankind, because since the Church is one and unique, she is seen as a sign raised up for the nations to see, inviting all to believe in Christ as sent by God come to save all men. The Church carries on this mission of salvation through its union with Christ, calling all mankind to join the Church and by so doing to share in union with Christ and the Father.
The Second Vatican Council, speaking of the principles of ecumenism, links the Church's unity with her universality: "Almost everyone, though in different ways, longs for the one visible Church of God, a Church truly universal and sent forth to the whole world that the world may be converted to the Gospel and so be saved, to the glory of God" ("Unitatis Redintegratio", 1). This universality is another characteristic of the Church, technically described as "catholicity". "For many centuries now the Church has been spread throughout the world, and it numbers persons of all races and walks of life. But the universality of the Church does not depend on its geographical distribution, even though this is a visible sign and of motive of credibility. The Church was catholic already at Pentecost: it was born catholic from the wounded heart of Jesus, as a fire which the Holy Spirit enkindled.
"In the second century the Christians called the Church catholic in order to distinguish it from sects, which, using the name of Christ, were betraying His doctrine in one way or another. `We call it catholic', writes St. Cyril, `not only because it is spread throughout the world, from one extreme to the other, but because in a universal way and without defect it teaches all the dogmas which men ought to know, of both the visible and the invisible, the celestial and the earthly. Likewise because it draws to true worship all types of men, governors and citizens, the learned and the ignorant. And finally, because it cures and heals all kinds of sins, whether of the soul or of the body, possessing in addition--by whatever name it may be called--all the forms of virtue, in deeds and in words and in every kind of spiritual life' ("Catechesis", 18, 23)" (St J. Escriva, "In Love with the Church", 9).
Every Christian should have the same desire for this unity as Jesus Christ expresses in His prayer to the Father. "A privileged instrument for participation in pursuit of the unity of all Christians is prayer. Jesus Christ Himself left us His final wish for unity through prayer to the Father: `that they also may be in us, so that the world may believe that Thou hast sent Me' (John 17:21).
"Also the Second Vatican Council strongly recommended to us prayer for the unity of Christians, defining it `the soul of the whole ecumenical movement' ("Unitatis Redintegratio", 8). As the soul to the body, so prayer gives life, consistency, spirit, and finality to the ecumenical movement.
"Prayer puts us, first and foremost, before the Lord, purifies us in intentions, in sentiments, in our heart, and produces that `interior conversion', without which there is no real ecumenism. (cf. "Unitatis Redintegratio", 7).
"Prayer, furthermore, reminds us that unity, ultimately, is a gift from God, a gift for which we must ask and for which we must prepare in order that we may be granted it" (St John Paul II, "General Audience", 17 January 1979).
22-23. Jesus possess glory, a manifestation of divinity, because He is God, equal to the Father (cf. note on John 17:1-5). When He says that He is giving His disciples this glory, He is indicating that through grace He makes us partakers of the divine nature (2 Peter 1:4). Glory and justification by grace are very closely united, as we can see from Sacred Scripture: "Those whom He predestined He also called, and those whom He called He also justified, and those whom He justified He also glorified" (Romans 8:30). The change grace works in Christians makes us ever more like Christ, who is the likeness of the Father (cf. 2 Corinthians 4:4; Hebrews 1:2-3): by communicating His glory Christ joins the faithful to God by giving them a share in supernatural life, which is the source of the holiness of Christians and of the Church: "Now we can understand better how [...] one of the principal aspects of her holiness is that unity centered on the mystery of the one and triune God. `There is one body and one Spirit, just as you were called to the one hope that belongs to your call, one Lord, one faith, one baptism; one God and Father of us all, who is above all and through all and in all' (Ephesians 4:4-6)" (St J. Escriva, "In Love with the Church", 5).
24. Jesus concludes His prayer by asking that all Christians attain the blessedness of Heaven. The word He uses, "I desire", not "I pray", indicates that He is asking for the most important thing of all, for what His Father wants--that all may be saved and come to a knowledge of the truth (cf. 1 Timothy 2:4): which is essentially the mission of the Church--the salvation of souls.
As long as we are on earth we share in God's life through knowledge (faith) and love (charity); but only in Heaven will we attain the fullness of this supernatural life, when we see God as He is (cf. 1 John 3:2), face to face (cf. 1 Corinthians 13:9-12). Therefore, the Church has her sights fixed on eternity, she is eschatological: that is, by having in this world all the resources necessary for teaching God's truth, for rendering Him true worship and communicating the life of grace, she keeps alive people's hope of attaining the fullness of eternal life: "The Church, to which we are all called in Christ Jesus, and in which by the grace of God we acquire holiness, will receive its perfection only in the glory of Heaven, when will come the time of the renewal of all things (Acts 3:21). At that time, together with the human race, the universe itself, which is so closely related to man and which attains its destiny through him, will be perfectly reestablished in Christ (cf. Ephesians 1:10; Colossians 1:20; 2 Peter 3:10-13)" (Vatican II, "Lumen Gentium", 48).
25-26. God's revelation of Himself through Christ causes us to begin to share in the divine life, a sharing which will reach its climax in Heaven: "God alone can give us right and full knowledge of this reality by revealing Himself as Father, Son and Holy Spirit, in whose eternal life we are by grace called to share, here below in the obscurity of faith and after death in eternal light" (St Paul VI, "Creed of the People of God").
Christ has revealed to us all we need to know in order to participate in the mutual love of the Divine Persons--primarily, the mystery of who He is and what His mission is and, with that, the mystery of God Himself ("I made known to them Thy name"), thus fulfilling what He had announced: "No one knows the Father except the Son and any one to whom the Son chooses to reveal Him" (Matthew 11:27).
Christ continues to make known His Father's love, by means of the Church, in which He is always present: "I am with you always, to the close of the age" (Matthew 28:20).
