Haydock's commentary
This is life everlasting; that is, the way to life everlasting, that they may know thee, the only true God, and Jesus Christ, whom thou hast sent2. The Arians, from these words, pretended that the Father only is the true God. St. Augustine and divers others answer, that the sense and construction is, that they may know thee, and also Jesus Christ thy Son, whom thou hast sent to be the only true God. We may also expound them with St. Chrysostom and others, so that the Father is here called the only true God, not to exclude the Son, and the Holy Ghost, who are the same one true God with the Father; but only to exclude the false gods of the Gentiles. Let the Socinians take notice, that (1 John v. 20.) the Son of God, Jesus Christ, is expressly called the true God, even with the Greek article, upon which they commonly lay so much stress. (Witham)
Life everlasting. Both the life of glory in heaven, and of grace here, consisteth in the knowledge of God; the former in perfect vision, the latter in faith working by charity. For knowledge of God, without keeping his commandments, is not true knowledge, but unprofitable knowledge. (1 John xi.[ii.?])

The Fathers on this verse
St John Chrysostom Catena Aurea on verses 1-5
After having said, In the world you shall have tribulation, our Lord turns from admonition to prayer; thus teaching us in our tribulations to abandon all other things, and flee to God.
St Bede Catena Aurea on verses 1-5
These things spoke Jesus, those things that He had said at the supper, partly sitting as far as the words, Arise, let us go hence; and thence standing, up to the end of the hymn which now commences, And lifted up His eyes and said, Father, the hour is come; glorify Your Son.
St John Chrysostom Catena Aurea on verses 1-5
He lifted up His eyes to heaven to teach us intentness in our prayers: that we should stand with uplifted eyes, not of the body only, but of the mind.
St Augustine Catena Aurea on verses 1-5
Our Lord, in the form of a servant, could have prayed in silence had He pleased; but He remembered that He had not only to pray, but to teach. For not only His discourse, but His prayer also, was for His disciples’ edification, yes and for ours who read the same. Father, the hour is come, shows that all time, and every thing that He did or suffered to be done, was at His disposing, Who is not subject to time. Not that we must suppose that this hour came by any fatal necessity, but rather by God’s ordering. Away with the notion, that the stars could doom to death the Creator of the stars.
St Hilary of Poitiers Catena Aurea on verses 1-5
He does not say that the day, or the time, but that the hour is come. An hour contains a portion of a day. What was this hour? He was now to be spit upon, scourged, crucified. But the Father glorifies the Son. The sun failed in his course, and with him all the other elements felt that death. The earth trembled under the weight of our Lord hanging on the Cross, and testified that it had not power to hold within it Him who was dying. The Centurion proclaimed, Truly this was the Son of God. The event answered the prediction. Our Lord had said, Glorify Your Son, testifying that He was not the Son in name only, but properly the Son. Your Son, He said. Many of us are sons of God; but not such is the Son. For He is the proper, true Son by nature, not by adoption, in truth, not in name, by birth, not by creation. Therefore after His glorifying, to the manifestation of the truth there succeeded confession. The Centurion confesses Him to be the true Son of God, that so none of His believers might doubt what one of His persecutors could not deny.
St Augustine Catena Aurea on verses 1-5
But if He was glorified by His Passion, how much more by His Resurrection? For His Passion rather showed His humility than His glory. So we must understand, Father, the hour is come, glorify Your Son, to mean, the hour is come for sowing the seed, humility; defer not the fruit, glory.
St Hilary of Poitiers Catena Aurea on verses 1-5
But perhaps this proves weakness in the Son; His waiting to be glorified by one superior to Himself. And who does not confess that the Father is superior, seeing that He Himself said, The Father is greater than I? But beware lest the honor of the Father impair the glory of the Son. It follows: That Your Son also may glorify You. So then the Son is not weak, inasmuch as He gives back in His turn glory for the glory which He receives. This petition for glory to be given and repaid, shows the same divinity to be in both.
St Augustine Catena Aurea on verses 1-5
But it is justly asked, how the Son can glorify the Father, when the eternal glory of the Father never experienced abasement in the form of man, and in respect of its own Divine perfection, does not admit of being added to. But among men this glory was less when God was only known in Judea; and therefore the Son glorified the Father, when the Gospel of Christ spread the knowledge of the Father among the Gentiles. Glorify Your Son, that Your Son also may glorify You; i.e. Raise Me from the dead, that by Me You may be known to the whole world. Then He unfolds further the manner in which the Son glorifies the Father; As You have given Him power over all flesh, that He should give eternal life to as many as You have given Him. All flesh signifies all mankind, the part being put for the whole. And this power which is given to Christ by the Father over all flesh, must be understood with reference to His human nature.
St Hilary of Poitiers Catena Aurea on verses 1-5
For being made flesh Himself, He was about to restore eternal life to frail, corporeal, and mortal man.
St Hilary of Poitiers Catena Aurea on verses 1-5
If Christ be God, not begotten, but unbegotten, then let this receiving be thought weakness. But not if His receiving of power signifies His begetting, in which He received what He is. This gift cannot be counted for weakness. For the Father is such in that He gives the Son remains God in that He has received the power of giving eternal life.
St John Chrysostom Catena Aurea on verses 1-5
He said, You have given Him power over all flesh, to show that His preaching extended not to the Jews only, but to the whole world. But what is all flesh? For all did not believe? So far as lay with Him, all did. If they did not attend to His words, it was not His fault who spoke, but theirs who did not receive.
St Augustine Catena Aurea on verses 1-5
He said, As You have given Him power over all flesh, so the Son may glorify You, i.e. make You known to all flesh which You have given Him; for You have so given it to Him, that He should give eternal life to as many as You have given Him.
St Hilary of Poitiers Catena Aurea on verses 1-5
And in what eternal life is, He then shows: And this is life eternal, that they might know You, the only true God. To know the only true God is life, but this alone does not constitute life. What else then is added? And Jesus Christ whom You have sent.
St Hilary of Poitiers Catena Aurea on verses 1-5
The Arians hold, that as the Father is the only true, only just, only wise God, the Son has no communion of these attributes; for that which is proper to one, cannot be partaken of by another. And as these are as they think in the Father alone, and not in the Son, they necessarily consider the Son a false and vain God.
St Hilary of Poitiers Catena Aurea on verses 1-5
But it must be clear to every one that the reality of any thing is evidenced by its power. For that is true wheat, which when rising with grain and fenced with ears, and shaken out by the winnowing machine, and ground into corn, and baked into bread, and taken for food, fulfills the nature and function of bread. I ask then wherein the truth of Divinity is wanting to the Son, Who has the nature and virtue of Divinity. For He so made use of the virtue of His nature, as to cause to be things which were not, and to do every thing which seemed good to Him.
St Hilary of Poitiers Catena Aurea on verses 1-5
Because He says, You the only, does He separate Himself from communion and unity with God? He does separate Himself, but that He adds immediately, And Jesus Christ Whom You have sent. For the Catholic faith confesses Christ to be true God, in that it confesses the Father to be the only true God; for natural birth did not introduce any change of nature into the Only-Begotten God.
St Augustine Catena Aurea on verses 1-5
Dismissing then the Arians, let us see if we are forced to confess, that by the words, That they may know You to be the only true God, He means us to understand that the Father only is the true God, in such sense as that only the Three together, Father, Son, and Holy Ghost, are to be called God? Does our Lord’s testimony authorize us to say that the Father is the only true God, the Son the only true God, and the Holy Ghost the only true God, and at the same time, that the Father, Son, and Holy Ghost together, i.e. the Trinity, are not three Gods, but one true God?
St Augustine Catena Aurea on verses 1-5
Or is not the order of the words, That they may know You and Jesus Christ, Whom You have sent, to be the only true God? the Holy Spirit being necessarily understood, because the Spirit is only the love of the Father and the Son, consubstantial with both. If then the Son so glorifies You as You have given Him power over all flesh, and You have given Him the power, that He should give eternal life to as many as You have given Him, and, This is life eternal, to know You, it follows that He glorifies You by making You known to all whom You have given Him. Moreover, if the knowledge of God is life eternal, the more advance we make in this knowledge, the more we make in life eternal. But in life eternal we shall never die. Where then there is no death, there will then be perfect knowledge of God; there will God be most glorified, because His glory will be greatest. Glory was defined among the ancients to be fame accompanied with praise. But if man is praised in dependence on what is said of him, how will God be praised when He shall be seen? as in the Psalm, Blessed are they who dwell in Your house: they will be always praising You. There will be praise of God without end, where will be full knowledge of God. There then shall be heard the everlasting praise of God, for there will there be full knowledge of God, and therefore full glorifying of Him.
St Augustine Catena Aurea on verses 1-5
What He said to His servant Moses, I am that I am; this we shall contemplate in the life eternal.
St Augustine Catena Aurea on verses 1-5
For when sight has made our faith truth, then eternity shall take possession of and displace our mortality.
St Augustine Catena Aurea on verses 1-5
But God is first glorified here, when He is proclaimed, made known to, and believed in, by men: I have glorified You on the earth.
St Hilary of Poitiers Catena Aurea on verses 1-5
This new glory with which our Lord had glorified the Father, does not imply any advancement in Godhead, but refers to the honor received from those who are converted from ignorance to knowledge.
St John Chrysostom Catena Aurea on verses 1-5
, He says, on the earth; for He had been glorified in heaven, both in respect of the glory of His own nature, and of the adoration of the Angels. The glory therefore here spoken of is not that which belongs to His substance, but that which pertains to the worship of man: wherefore it follows, I have finished the work which You gave Me to do.
St Augustine Catena Aurea on verses 1-5
Not You command Me, but, You gave Me, implying evidently grace. For what has human nature, even in the Only-Begotten, what it has not received? But how had He finished the work which had been given Him to do, when there yet remained His passion to undergo? He says He has finished it, i.e. He knows for certain that He will.
St John Chrysostom Catena Aurea on verses 1-5
Or, I have finished, i.e. He had done all His own part, or had done the chief of it, that standing for the whole; (for the root of good was planted:) or He connects Himself with the future, as if it were already present.
St Hilary of Poitiers Catena Aurea on verses 1-5
After which, that we may understand the reward of His obedience, and the mystery of the whole dispensation, He adds, And now glorify Me with the glory with Your own Self, with the glory which I had with You before the world was.
St Augustine Catena Aurea on verses 1-5
He had said above, Father, the hour is come: glorify Your Son, that Your Son also may glorify You: the order of which words shows that the Son was first to be glorified by the Father, that the Father might be glorified by the Son. But now He says, I have glorified You; and now glorify Me, as if He had first glorified the Father, and then asked to be glorified by Him. We must understand that the first is the order in which one was to succeed the other, but that He afterwards uses a past tense, to express a thing future; the meaning being, I will glorify You on the earth, by finishing the work you have given Me to do: and now, Father, glorify Me, which is quite the same sentence with the first one, except that He adds here the mode in which He is to be glorified; with the glory which I had before the world was, with You. The order of the words is, The glory which I had with you before the world was. This has been taken by some to mean, that the human nature which was assumed by the Word, would be changed into the Word, that man would be changed into God, or, to speak more correctly, be lost in God. For no one would say that the Word of God would by that change be doubled, or even made at all greater. But we avoid this error, if we take the glory which He had with the Father before the world was, to be the glory which He predestined for Him on earth: (for if we believe Him to be the Son of man, we need not be afraid to say that He was predestined.) This predestined time of His being glorified, He now saw was arrived, that He might now receive what had been aforetime predestined, He prayed accordingly: And now, Father, glorify Me, &c. i.e. that glory which I had with you by your predestination, it is now time that I should have at your right hand.
St Hilary of Poitiers Catena Aurea on verses 1-5
Or He prayed that that which was mortal, might receive the glory immortal, that the corruption of the flesh might be transformed and absorbed into the incorruption of the Spirit.
Pseudo-Ignatius Epistle to the Antiochians, Chapter IV. Continuation
The Evangelists, too, when they declared that the one Father was “the only true God,” did not omit what concerned our Lord, but wrote: “In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made by Him, and without Him was not anything made that was made.” And concerning the incarnation: “The Word,” says [the Scripture], “became flesh, and dwelt among us.” And again: “The book of the generation of Jesus Christ, the son of David, the son of Abraham.” And those very apostles, who said “that there is one God,” said also that “there is one Mediator between God and men.” Nor were they ashamed of the incarnation and the passion. For what says [one]? “The man Christ Jesus, who gave Himself” for the life and salvation of the world.
St Cyprian The Epistles of Cyprian, Epistle LXXII
17. For whereas in the Gospels, and in the epistles of the apostles, the name of Christ is alleged for the remission of sins; it is not in such a way as that the Son alone, without the Father, or against the Father, can be of advantage to anybody; but that it might be shown to the Jews, who boasted as to their having the Father, that the Father would profit them nothing, unless they believed on the Son whom He had sent. For they who know God the Father the Creator, ought also to know Christ the Son, lest they should flatter and applaud themselves about the Father alone, without the acknowledgment of His Son, who also said, “No man cometh to the Father but by me.” But He, the same, sets forth, that it is the knowledge of the two which saves, when He says, “And this is life eternal, that they might know Thee, the only true God, and Jesus Christ, whom thou hast sent.” Since, therefore, from …
St Cyprian Treatise IV
28. What wonder is it, beloved brethren, if such is the prayer which God taught, seeing that He condensed in His teaching all our prayer in one saving sentence? This had already been before foretold by Isaiah the prophet, when, being filled with the Holy Spirit, he spoke of the majesty and loving-kindness of God, “consummating and shortening His word,” He says, “in righteousness, because a shortened word will the Lord make in the whole earth.” For when the Word of God, our Lord Jesus Christ, came unto all, and gathering alike the learned and unlearned, published to every sex and every age the precepts of salvation, He made a large compendium of His precepts, that the memory of the scholars might not be burdened in the celestial learning, but might quickly learn what was necessary to a simple faith. …
St Cyprian Treatise V
23. Look, therefore, while there is time, to the true and eternal salvation; and since now the end of the world is at hand, turn your minds to God, in the fear of God; nor let that powerless and vain dominion in the world over the just and meek delight you, since in the field, even among the cultivated and fruitful corn, the tares and the darnel have dominion. Nor say ye that ill fortunes happen because your gods are not worshipped by us; but know that this is the judgment of God’s anger, that He who is not acknowledged on account of His benefits may at least be acknowledged through His judgments. …
St Cyprian Treatise XI, Chapter II
“As it is written, Thou shalt worship the Lord thy God, and Him only shalt thou serve.” Also in Exodus: “Thou shalt have none other gods beside me.” Also in Deuteronomy: “See ye, see ye that I am He, and that there is no God beside me. I will kill, and will make alive; I will smite, and I will heal; and there is none who can deliver out of mine hands.” In the Apocalypse, moreover: “And I saw another angel fly in the midst of heaven, having the everlasting Gospel to preach over the earth, and over all nations, and tribes, and tongues, and peoples, saying with a loud voice, Fear God rather, and give glory to Him: for the hour of His judgment is come; and worship Him that made heaven and earth, and the sea, and all that therein is.” So also the Lord, in His Gospel, makes mention of the first and second commandment, saying, “Hear, O Israel, The Lord thy God is one God;” and, “Thou shalt love …
St Cyprian Three Books of Testimonies Against the Jews, That Christ is the First-born, and that He is the Wisdom of God, by whom all things were made
In Solomon in the Proverbs: “The Lord established me in the beginning of His ways, into His works: before the world He founded me. In the beginning, before He made the earth, and before He appointed the abysses, before the fountains of waters gushed forth, before the mountains were settled, before all the hills, the Lord begot me. He made the countries, and the uninhabitable places, and the uninhabitable bounds under heaven. When He prepared the heaven, I was present with Him; and when He set apart His seat. …
Novatian A Treatise of Novatian Concerning the Trinity, Chapter XVI
If Christ was only man, how is it that He Himself says, “And every one that believeth in me shall not die for evermore?” And yet he who believes in man by himself alone is called accursed; but he who believes on Christ is not accursed, but is said not to die for evermore. Whence, if on the one hand He is man only, as the heretics will have it, how shall not anybody who believes in Him die eternally, since he who trusts in man is held to be accursed? Or on the other, if he is not accursed, but rather, as it is read, destined for the attainment of everlasting life, Christ is not man only, but God also, in whom he who believes both lays aside all risk of curse, and attains to the fruit of righteousness. …
Novatian A Treatise of Novatian Concerning the Trinity, Chapter XXVI
But from this occasion of Christ being proved from the sacred authority of the divine writings not man only, but God also, other heretics, breaking forth, contrive to impair the religious position in Christ; by this very fact wishing to show that Christ is God the Father, in that He is asserted to be not man only, but also is declared to be God. For thus say they, If it is asserted that God is one, and Christ is God, then say they, If the Father and Christ be one God, Christ will be called the Father. Wherein they are proved to be in error, not knowing Christ, but following the sound of a name; for they are not willing that He should be the second person after the Father, but the Father Himself. And since these things are easily answered, few words shall be said. …
The Apostolic Constitutions Book V, Sec. III. On Feast Days and Fast Days
XVI . See how the people provoked the Lord by not believing in Him! Therefore He says: “They provoked the Holy Spirit, and He was turned to be their enemy.” For blindness is cast upon them, by reason of the wickedness of their mind, because when they saw Jesus they did not believe Him to be the Christ of God, who was before all ages begotten of Him, His only-begotten Son, God the Word, whom they did not own through their unbelief, neither on account of His mighty works, nor yet on account of the prophecies which were written concerning Him. …
The Apostolic Constitutions Book VI, Sec. IV. Of the Law
XXIII . For He did not take away the law of nature, but confirmed it. For He that said in the law, “The Lord thy God is one Lord;” the same says in the Gospel, “That they might know Thee, the only true God.” And He that said, “Thou shalt love thy neighbour as thyself,” says in the Gospel, renewing the same precept, “A new commandment I give unto you, that ye love one another.” He who then forbade murder, does now forbid causeless anger. He that forbade adultery, does now forbid all unlawful lust. He that forbade stealing, now pronounces him most happy who supplies those that are in want out of his own labours. He that forbade hatred, now pronounces him blessed that loves his enemies. He that forbade revenge, now commands long-suffering; not as if just revenge were an unrighteous thing, but because long-suffering is more excellent. …
Origen Origen's Commentary on the Gospel of John, Chapter II
We next notice John’s use of the article in these sentences. He does not write without care in this respect, nor is he unfamiliar with the niceties of the Greek tongue. In some cases he uses the article, and in some he omits it. He adds the article to the Logos, but to the name of God he adds it sometimes only. He uses the article, when the name of God refers to the uncreated cause of all things, and omits it when the Logos is named God. Does the same difference which we observe between God with the article and God without it prevail also between the Logos with it and without it? We must enquire into this. As the God who is over all is God with the article not without it, so “the Logos” is the source of that reason (Logos) which dwells in every reasonable creature; the reason which is in each creature is not, like the former called par excellence The Logos. …
St Augustine On the Holy Trinity, The Texts of Scripture Explained Respecting the Subjection of the Son to the Father, Which Have Been Misunderstood. Christ Will Not So Give Up the Kingdom to the Father, as to Take It Away from Himself. The Beholding Him is the Promised End of All Actions. The Holy Spirit is Sufficient to Our Blessedness Equally with the Father
17. For this contemplation is held forth to us as the end of all actions, and the everlasting fullness of joy. For “we are the sons of God; and it doth not yet appear what we shall be: but we know that, when He shall appear, we shall be like Him; for we shall see Him as He is.” For that which He said to His servant Moses, “I am that I am; thus shalt thou say to the children of Israel, I Am hath sent me to you;” this it is which we shall contemplate when we shall live in eternity. For so it is said, “And this is life eternal, that they might know Thee, the only true God, and Jesus Christ, whom Thou hast sent.” This shall be when the Lord shall have come, and “shall have brought to light the hidden things of darkness;” when the darkness of this present mortality and corruption shall have passed away. …
29 more passages of the Fathers cite this verse. The Motif Searcher in the palace lists them all.
The Fathers are given as they wrote. Where a passage lays the Passion on the Jewish people, the Church teaches that it cannot be charged against all the Jews then living, nor against the Jews of today, and that all sinners were its authors (CCC 597, 598).
