36 He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him.
[AD 108] Ignatius of Antioch on John 3:36
Do ye, beloved, be careful to be subject to the bishop, and the presbyters and the deacons. For he that is subject to these is obedient to Christ, who has appointed them; but he that is disobedient to these is disobedient to Christ Jesus. And "he that obeyeth not the Son shall not see life, but the wrath of God abideth on him." For he that yields not obedience to his superiors is self-confident, quarrelsome, and proud. But" God," says [the Scripture] "resisteth the proud, but giveth grace to the humble ; " and, "The proud have greatly transgressed." The Lord also says to the priests, "He that heareth you, heareth Me; and he that heareth Me, heareth the Father that sent Me. He that despiseth you, despiseth Me; and he that despiseth Me, despiseth Him that sent Me."

[AD 202] Irenaeus on John 3:36
And for this reason, "he that believeth in Him has eternal life while he who believeth not the Son hath not eternal life, but the wrath of God shall remain upon him."

[AD 258] Cyprian on John 3:36
That it is impossible to attain to God the Father, except by His Son Jesus Christ. In the Gospel: "I am the way, and the truth, and the life: no one cometh to the Father but by me." Also in the same place: "I am the door: by me if any man shall enter in, he shall be saved." Also in the same place: "Many prophets and righteous men have desired to see the things which ye see, and have not seen them; and to hear those things which ye hear, and have not heard them." Also in the same place: "He that believeth on the Son hath eternal life: he that is not obedient in word to the Son hath not life; but the wrath of God shall abide upon him." Also Paul to the Ephesians: "And when He had come, He preached peace to you, to those which are afar off, and peace to those which are near, because through Him we both have access in one Spirit unto the Father." Also to the Romans: "For all have sinned, and fail of the glory of God; but they are justified by His gift and grace, through the redemption which is in Christ Jesus." Also in the Epistle of Peter the apostle: "Christ hath died once for our sins, the just for the unjust, that He might present us to God." Also in the same place: "For in this also was it preached to them that are dead, that they might be raised again." Also in the Epistle of John: "Whosoever denieth the Son, the same also hath not the Father. He that confesseth the Son, hath both the Son and the Father."

[AD 380] Apostolic Constitutions on John 3:36
By believing in Him you shall live, but by disbelieving you shall be punished. For "he that is disobedient to the Son shall not see life, but the wrath of God abideth on him."

[AD 397] Ambrose of Milan on John 3:36
The wrath that remains on him certainly had its beginning from some offence, in other words, first of all, that he did not believe. When, then, anyone believes, the wrath of God departs and life arrives. To believe, then, in Christ is to gain life, for “He who believes in him is not judged.”

[AD 407] John Chrysostom on John 3:36
(Hom. xxxi. 1) He means not here, that to believe on the Son is sufficient to gain everlasting life, for elsewhere He says, Not every one that saith unto Me, Lord, Lord, shall enter into the kingdom of heaven. (Matt. 7) And the blasphemy against the Holy Ghost is of itself sufficient to send into hell. But we must not think that even a right belief on Father, Son, and Holy Ghost, is sufficient for salvation; for we have need of a good life and conversation. Knowing then that the greater part are not moved so much by the promise of good, as by the threat of punishment, he concludes, But He that believeth not the Son, shall not see life; but the wrath of God abideth on him. See how He refers to the Father again, when He speaketh of punishment. He saith not, the wrath of the Son, though the Son is judge; but maketh the Father the judge, in order to alarm men more. And He does not say, in Him, but on Him, meaning that it will never depart from Him; and for the same reason He says, shall not see life, i. e. to show that He did not mean only a temporary death.

[AD 407] John Chrysostom on John 3:36
"Is it then enough," saith one, "to believe on the Son, that one may have eternal life?" By no means. And hear Christ Himself declaring this, and saying, "Not every one that saith unto Me, Lord, Lord, shall enter into the kingdom of heaven"; and the blasphemy against the Spirit is enough of itself to cast a man into hell. But why speak I of a portion of doctrine? Though a man believe rightly on the Father, the Son, and the Holy Ghost, yet if he lead not a right life, his faith will avail nothing towards his salvation. Therefore when He saith, "This is life eternal, that they may know Thee the only true God," let us not suppose that the knowledge spoken of is sufficient for our salvation; we need besides this a most exact life and conversation. Since though he has said here, "He that believeth on the Son hath eternal life," and in the same place something even stronger, (for he weaves his discourse not of blessings only, but of their contraries also, speaking thus: "He that believeth not the Son shall not see life, but the wrath of God abideth on him";) yet not even from this do we assert that faith alone is sufficient to salvation. And the directions for living given in many places of the Gospels show this. Therefore he did not say, "This by itself is eternal life," nor, "He that doth but believe on the Son hath eternal life," but by both expressions he declared this, that the thing doth contain life, yet that if a right conversation follow not, there will follow a heavy punishment. And he did not say, "awaiteth him," but, "abideth on him," that is, "shall never remove from him." For that thou mayest not think that the "shall not see life," is a temporary death, but mayest believe that the punishment is continual, he hath put this expression to show that it rests upon him continually.

[AD 430] Augustine of Hippo on John 3:36
“Whoever believes in the Son has eternal life.” Why? Because he has done the work of God, seeing that this is the work of God that you should believe in the one whom he has sent. “But whoever does not believe in the Son will not have life, but the wrath of God remains on him”; not “will come upon him” but “remains on him.” He is abandoned, not healed.

[AD 430] Augustine of Hippo on John 3:36
Carnal thought does not apprehend what I say: let it defer understanding, and begin by faith; let it hear what follows: "He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him." He has not said, The wrath of God cometh to him; but, "The wrath of God abideth on him." All that are born mortals have the wrath of God with them. What wrath of God? That wrath which Adam first received. For if the first man sinned, and heard the sentence, "Thou shalt die the death," he became mortal, and we began to be born mortal; and we have been born with the wrath of God. From this stock came the Son, not having sin, and He was clothed with flesh and mortality. If He partook with us of the wrath of God, are we slow to partake with Him the grace of God? He, then, that will not believe the Son, on the same "the wrath of God abideth." What wrath of God? That of which the apostle says, "We also were by nature the children of wrath, even as the rest." All are therefore children of wrath, because coming of the curse of death. Believe on Christ, for thee made mortal, that thou mayest receive Him, the immortal; and when thou shalt have received His immortality, thou shalt no longer be mortal. He lived, thou wast dead; He died that thou shouldst live. He has brought us the grace of God, and has taken away the wrath of God. God has conquered death, lest death should conquer man.

[AD 430] Augustine of Hippo on John 3:36
(Tr. xiv. c. 13) Nor does He say, The wrath of God cometh to him, but, abideth on him. For all who are born, are under the wrath of God, which the first Adam incurred. The Son of God came without sin, and was clothed with mortality: He died that thou mightest live. Whosoever then will not believe on the Son, on him abideth the wrath of God, of which the Apostle speaks, We were by nature the children of wrath. (Eph. 2:3)

[AD 444] Cyril of Alexandria on John 3:36
and he that believeth not the Son shall not see life.

Doth then (will haply some one say) the Baptist preach to us another opinion, and corrupt the doctrine of the resurrection, saying that he that believeth shall be quickened, wholly asserting that he that doth not shall not see life? We shall not all, it seems, rise; his word introducing to us this distinction. Whither then will that pass away, that is said absolutely and as it were to all, The dead shall be raised? What is Paul too about, saying, For we must all appear before the judgement seat of Christ, that every one may receive the things done in his body, according to that he hath done, whether it be good or bad? I suppose then that he that is eager after learning ought to be praised, nevertheless most accurate scrutiny must be made in Holy Scripture. For see clearly, I pray you, the distinction between the things said. For of the believer he says that he shall have everlasting life, of the unbeliever, the word hath a different significance. For he does not say that he shall not have life: for he shall be raised by the common law of the resurrection; but he says that he shall not see life, that is, he shall not so much as arrive at the bare sight of the life of the saints, he shall not touch their blessedness, he shall remain untasting of their life passed in bliss. For that is indeed life. But to exist in punishment is bitterer than all death, holding the soul in the body only for the sensation of sufferings. Some such difference in life Paul also brings forward. Hear what he says to those who are dead to evil for Christ's sake, For ye are dead, and your life is hid with Christ in God; when Christ, your life, shall appear, then shall ye also appear with Him in glory. Seest thou how he calls appearing in glory with Christ the life of the saints? But what when the Psalmist too sings to us, saying, What man is he that desireth life, and loveth many days, that he may see good? Keep thy tongue from evil. Shall we not say that herein is signified the life of the saints? but it is, I think, evident to all. For he does not, forsooth, bid some to refrain from evil, that they may obtain the resurrection of the flesh hereafter (for they will rise again even if they do not cease from evil), but he rouses them rather to that life, wherein they may wholly see good days, passing an endless life in bliss and glory.

[AD 444] Cyril of Alexandria on John 3:36
He that believeth on the Son hath everlasting life.

Not simply, nor without examination doth the most wise Baptist testify that to them that believe in Christ is life set forth, as their Reward, but he brings forth to us the proof of it from the very quality so to speak of things. For the Only Begotten is by Nature Life: for in Him we live and move and are. But He is introduced into us of a surety through faith, and dwelleth in us through the Holy Ghost: and the blessed John the Evangelist will testify saying in his epistles Hereby know we that He dwelleth in us, because He hath given us of His Spirit. Christ will therefore quicken them that believe in Him, as being Himself Life by Nature and |199 dwelling in them. But that the Son indwelleth in us by faith, Paul will furnish proof, saying, For this cause I bow my knees unto the Father, of Whom the whole family in heaven and earth is named, that He would grant you according to the riches of His glory, to be strengthened with might by His Spirit; that Christ may dwell in your hearts by faith. Since then through faith Life by Nature entereth into us, how is he not true that saith, He that believeth on the Son hath everlasting Life? that is to say, the Son Himself, nought else than Him being conceived of as Life.

[AD 444] Cyril of Alexandria on John 3:36
but the wrath of God abideth on him.

More openly by means of this which follows did the blessed Baptist show us the aim of what has been said. Let him who loves to search consider carefully the force of the thought. He that believeth not (he saith) on the Son shall not see life, but the wrath of God abideth on him. But if it were possible to understand that the unbeliever should be indeed bereft of the life in the body, he would surely have immediately added, "but death abideth on him." But since he calls it the wrath of God, it is plain that he is contrasting the punishment of the ungodly with the enjoyments of the saints, and that he calls that life, which is the true life in glory with Christ, and the torments of the ungodly, the wrath of God. That punishment is ofttimes called wrath by the Divine Scriptures, I will adduce two witnesses, Paul and John: for the one said to the converted among the Gentiles, And were by nature the children of wrath, even as others; and the other to the Scribes and Pharisees, O generation of vipers, who hath warned you to flee from the wrath to come?

[AD 444] Cyril of Alexandria on John 3:36
He says that the believer shall have everlasting life, but the word has a different significance for the unbeliever. For he does not say that [the unbeliever] shall not have life since he too shall be raised by the common law of the resurrection. But he says that he shall not see life, that is, he shall not even so much as glimpse the life of the saints, he shall not touch their blessedness, and he shall not taste of their life spent in bliss. For that is indeed life. But to exist in punishment is far more bitter than any death, holding the soul in the body only for the sensation of suffering.

[AD 735] Bede on John 3:36
We must understand here not a faith in words only, but a faith which is developed in works.

[AD 804] Alcuin of York on John 3:36
And because all things are in His hand, the life everlasting is too: and therefore it follows, He that believeth on the Son hath everlasting life.
