And this is life eternal, that they might know you the only true God, and Jesus Christ, whom you have sent.

Arnobius of Sicca
Jaws of death; that they can, nevertheless, have their lives prolonged by the favour and kindness of the Supreme Ruler if only they try and study to know Him,-for the knowledge of Him is a kind of vital leaven
But this is life eternal, to know Thee the only true God and Jesus Christ whom Thou hast sent. This saying agrees exactly with what precedes. Christ gives the reason for seeking to be glorified. Because this glorification is the knowledge of God and of Christ, which is the only way to eternal life. His argument is this, "Glorify Me, that I may glorify Thee, so that by this glorifying or manifestation they may attain eternal life." For life eternal consists in knowing Thee, and Jesus Christ whom Thou hast sent, in order that they who believe in Him may be saved. For no one can be saved, except by Faith in Christ.
This is life eternal. (1.) S. Thomas (Par. i. Qust. xii4,6 , and par. iii. Qust. iii. art4 , and Contra Gentes iii. cap61 , and elsewhere), understands these words in their formal sense, and hence proves that the essence of beatitude consists in an act of the intellect, not of the will. And he thus explains it, "Glorify Me, that thus the faithful may obtain eternal life, which...
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.".
Thus, when He taught what is life eternal, He embraced the sacrament of life in a large and divine brevity, saying, "And this is life eternal, that they might know Thee, the only and true God, and Jesus Christ, whom Thou hast sent.".
Know God even late; for Christ at His coming admonishes and teaches this, saying, "This is life eternal, that they might know Thee, the only true God, and Jesus Christ, whom Thou hast sent.".
And once more: "And this is life eternal, that they may know Thee, the only and true God, and Jesus Christ, whom Thou hast sent.".
And now, do Thou glorify me with Thyself, with the glory which I had with Thee before the world was made." ...
CHAPTER V. That the Son will not be excluded from being true God, even though He named God the Father the only true God.
He defines faith as the mother of eternal life, and says that the power of the true knowledge of God will be such as to cause us to remain for ever in a state of incorruption, and blessedness, and sanctification. And we say that that is true knowledge of God, which cannot incur the reproach of turning aside to aught else, or running after things unseemly. For some have worshipped the creature rather than the Creator, and have dared to say to a block of wood: Thou art my Father; and to a stone, Thou hast begotten me. For to such abysmal ignorance did miserable men relapse, that they even gave, in all its fulness, the great Name of God, to senseless blocks of wood; and invested them with the ineffable glory of that Nature, which is over all. He calls God the Father, then, the only true God, by contrast to spurious gods, and with the intention to distinguish the true...
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 sent. 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 Spirit, 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 lat...
The only true God, He says, by way of distinction from those which are not gods; for He was about to send them to the Gentiles. But if they will not allow this, but on account of this word only reject the Son from being true God, in this way as they proceed they reject Him from being God at all. For He also says, You seek not the glory which is from the only God. John 5:44 Well then; shall not the Son be God? But if the Son be God, and the Son of the Father who is called the Only God, it is clear that He also is true, and the Son of Him who is called the Only true God. Why, when Paul says, Or I only and Barnabas 1 Corinthians 9:6, does he exclude Barnabas? Not at all; for the only is put by way of distinction from others. And, if He be not true God, how is He Truth? For truth far surpasses what is true. What shall we call the not being a true man, tell me? Shall we not call it the not being a man at all? So if the Son is not true God, how is He God? And how makes He us gods and sons,...
And since these things are so, as we have shown, it is plain that no other hope of life is set before man, except that, laying aside vanities and wretched error, he should know God.
these except God, who has proposed to us virtue itself? Therefore the sum and substance of everything is contained in the acknowledging and worship of God; all the hope and safety of man centres in this; this is the first step of wisdom, to know who is our true Father, and to worship Him alone with the piety which is due to Him, to obey Him, to yield ourselves to His service with the utmost devotedness: let our entire acting, and care, and attention, be laid out in gaining His favour.
But the second step is to perceive with the mind that there is but one Supreme God, whose power and providence made the world from the beginning, and afterwards continues to govern it. The third step is to know His Servant and Messenger, ...
