1 John 1:8

8 If we say that we have no sin, we deceive ourselves, and the truth is not in us.
Commentaries
Tertullianon 1 John 1:8AD 220
If we confess our sins, faithful and just is He to remit them to us, and utterly purify us from every unrighteousness." Does he say "from impurity? "(No): or else, if that is so, then (He "utterly purifies" us) from "idolatry" too.

Cyprianon 1 John 1:8AD 258
Let us then acknowledge, beloved brethren, the wholesome gift of the divine mercy; and let us, who cannot be without some wound of conscience, heal our wounds by the spiritual remedies for the cleansing and purging of our sins. Nor let any one so flatter himself with the notion of a pure and immaculate heart, as, in dependence on his own innocence, to think that the medicine needs not to be applied to his wounds; since it is written, "Who shall boast that he hath a clean heart, or who shall boast that he is pure from sins? " And again, in his epistle, John lays it down, and says, "If we say that we have no sin, we deceive ourselves, and the truth is not in us." But if no one can be without sin, and whoever should say that he is without fault is either proud or foolish, how needful, how kind is the divine mercy, which, knowing that there are still found some wounds in those that have been healed, even after their healing, has given wholesome remedies for the curing and healing of their wounds anew!
Cyprianon 1 John 1:8AD 258
That no one is without filth and without sin. In Job: "For who is pure from filth? Not one; even if his life be of one day on the earth." Also in the fiftieth Psalm: "Behold, I was conceived in iniquities, and in sins hath my mother conceived me." Also in the Epistle of John: "If we say that we have no sin, we deceive ourselves, and the truth is not in us."
Cyprianon 1 John 1:8AD 258
After this we also entreat for our sins, saying, "And forgive us our debts, as we also forgive our debtors." After the supply of food, pardon of sin is also asked for, that he who is fed by God may live in God, and that not only the present and temporal life may be provided for, but the eternal also, to which we may come if our sins are forgiven; and these the Lord calls debts, as He says in His Gospel, "I forgave thee all that debt, because thou desiredst me." And how necessarily, how providently and salutarily, are we admonished that we are sinners, since we are compelled to entreat for our sins, and while pardon is asked for from God, the soul recalls its own consciousness of sin! Lest any one should flatter himself that he is innocent, and by exalting himself should more deeply perish, he is instructed and taught that he sins daily, in that he is bidden to entreat daily for his sins. Thus, moreover, John also in his epistle warns us, and says, "If we say that we have no sin, we deceive ourselves, and the truth is not in us; but if we confess our sins, the Lord is faithful and just to forgive us our sins." In his epistle he has combined both, that we should entreat for our sins, and that we should obtain pardon when we ask. Therefore he said that the Lord was faithful to forgive sins, keeping the faith of His promise; because He who taught us to pray for our debts and sins, has promised that His fatherly mercy and pardon shall follow.
Didymus the Blindon 1 John 1:8AD 398
Since God is light, there is no darkness in him at all, and he has nothing to do with darkness. The person who is enlightened by his light walks in the light, according to the words of the Savior himself: "While you have the light, walk in the light, lest the darkness take hold of you." Anyone who walks in the darkness of sin but claims that his mind is not darkened and that he has a relationship with God is lying.

Augustine of Hippoon 1 John 1:8AD 430
"If we say that we have no sin, we deceive ourselves, and the truth is not in us." Consequently, if thou hast confessed thyself a sinner, the truth is in thee: for the Truth itself is light. Thy life hath not yet shone in perfect brightness, because there are sins in thee; but yet thou hast already begun to be enlightened, because there is in thee the confession of sins.
Hilary of Arleson 1 John 1:8AD 449
If you say that you are not a sinner but act otherwise, you are deceiving yourself.

If we say that we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, he is faithful and just to forgive us of our sins and to cleanse us from all unrighteousness. If we say that we have not sinned, we make him a liar, and his word is not in us.
"If we confess our sins." John repeats the statement, using it more richly, so that the frequency of the produced refutation may restrain them by the degree of sin itself and invite them to confession. However, John indicated how much good arises from confession when he said: "Say your sins first, so that you may be justified." (Is. 43:26) However, it was also the custom of the Teacher of this beloved disciple to repeat the same things more frequently, first moderately, then more perfectly, wishing to make the understanding of the words more effective, and striving to instill their habit into the listeners.
Indeed, John called God faithful. This means "truthful". For "Πιστός", that is, "faithful", is said not only of one to whom something is entrusted, but also of one who is confirmed in truth, who by his truthful manner causes others to become partakers of this as well. Therefore, God is called faithful in this way: just, indeed, as one who does not reject those who approach him, regardless of the sins they have committed. Therefore, he undoubtedly forgives the sins of those who run to holy baptism through repentance, whether they have sinned against him or against another.
There, if we confess, John says, we shall obtain appropriate forgiveness. But if we shamelessly say that we have not sinned, we shall commit a double evil, both showing ourselves to be liars and slandering God, who surpasses all truth, with falsehood. For He Himself says through the Prophet: "They have repaid me evil for good." (Ps. 109:5)
And again from John's own mouth: "If I have spoken wrongly, testify to the wrong; but if rightly, why do you strike me?" (Jn. 18:23) If, with these things being so, we still say that we have not sinned, we deny his words, which are spirit and life. (Jn. 6:64) "For the words that I speak," he says, "are spirit and life." And if we no longer have his word dwelling in us: what could be more serious?
Gregory the Dialogiston 1 John 1:8AD 604
Finally, it must be asked why in our Redeemer Himself, the Mediator between God and men, the Spirit appeared through a dove, but in the disciples through fire? Certainly the only-begotten Son of God is the judge of the human race. But who could endure His justice if, before gathering us through gentleness, He had wished to examine our faults through zeal for righteousness? Therefore, made man for men, He showed Himself gentle to men. He did not wish to strike sinners, but to gather them. First He wished to correct gently, so that He might have those whom He would afterward save in judgment. Therefore the Spirit ought to have appeared over Him in a dove, since He was not coming to strike sins now through zeal, but still to tolerate them through gentleness. But on the contrary, the Holy Spirit ought to have been shown over the disciples in fire, so that those who were simply men, and therefore sinners, He might kindle as spiritual servants against themselves, and the sins which God would spare through gentleness, they themselves might punish in themselves through repentance. For neither could they themselves be without sin who were clinging to the heavenly teaching, as John attests, who says: If we say that we have no sin, we deceive ourselves, and the truth is not in us. Therefore He came in fire upon men, but appeared in a dove upon the Lord, because the sins which the Lord piously tolerates through gentleness, we ought to carefully observe through zeal for righteousness, and always burn away with the fire of repentance.
Andreas of Caesareaon 1 John 1:8AD 614
This is how John describes the Jews who dared to say: "Let his blood be upon us and upon our children," as if they could crucify Christ without being sinners. If we say such things, we deceive ourselves.

Bedeon 1 John 1:8AD 735
If we say that we have no sin, etc. This sentence avails against the heresy of Pelagius, which claimed that all infants are born without sin and that the elect in this life can progress to such an extent as to be without sin. For even when the prophet says: "Behold, I was conceived in iniquity, and in sin my mother bore me" (Psalm 50), we cannot be without guilt in the world, having come into the world with guilt. But the blood of Jesus Christ, the Son of God, cleanses us from all sin so that our debts do not hold us under the power of our enemy, because the Mediator between God and man, the man Christ Jesus, freely repaid on our behalf what He did not owe. For He who undeservedly paid the debt of death in the flesh for us, freed us from the debt of the death of the soul.
Theophylact of Ohridon 1 John 1:5-8AD 1107
The Apostle again returns to his former discourse and explains what Gospel he heard, namely the following: God is light, and there is no darkness in Him. From whom did he hear this? From Christ Himself, Who said: "I am the light of the world" (John 8:12), and again: "I have come as a light into the world" (John 12:46). So then, He is light, and there is no darkness in Him, but a spiritual light that draws the eyes of the soul to behold Him, turning them away from everything material and arousing desire for Him alone with the most fervent love. By "darkness" he means either ignorance or sin; for in God there is neither ignorance nor sin, because ignorance and sin have their place in matter and in our disposition. And if it is said somewhere: "He made darkness His covering" (Ps. 18:12), it says that He "made" darkness, not that He "is" darkness, as it says He "is" light. For that which sets in place and that which is set in place are not the same thing. So here "darkness" signifies our ignorance about God, on account of His incomprehensibility, and this ignorance is ours, not God's. For sometimes something is attributed to one in whom it does not exist, not for his own sake, but for the sake of someone who has a relation to him. And that the Apostle calls sin darkness is evident from his Gospel saying: "and the light shines in the darkness, and the darkness did not overcome it" (John 1:5), where by darkness he means our sinful nature, which by its inclination toward falling yields to our envious adversary the devil, who drags us into sin. So then, the Light, having united Himself with our nature, which is so easily seized, became completely unseizable by the tempter. For "He committed no sin" (Isa. 53:9). So then, when we receive you as sharers in communion with God, Who is light, and in this light, as has been shown, there can be no darkness, then we too, as sharers of the light, must not admit darkness into ourselves, lest we suffer punishment for falsehood and together with falsehood be cut off from communion with the light. Therefore, holding to communion with one another, that is, with us and with the light, we must make ourselves unconquerable by sin. But how will this be, when we have already been mired in many sins before? For no one who loves truth and strives to be truthful will dare to say that he is without sin. So then, if anyone is seized by this fear, let him not despair: for whoever has entered into communion with His Son Jesus Christ has been cleansed by His Blood, shed for us. Note that on account of the most intimate union he calls Him the Son of the Father even according to what was assumed by Him from us; for blood, without doubt, belongs to our nature, not to God. And Nestorius is clearly insane and impious when he separates the flesh from the Son and does not allow His Mother to be called the Theotokos. One must also know that the entire thought of this passage overthrows the blasphemy of the Jews as well, who said: "We know that this Man is a sinner" (John 9:24). So then, he says, if we do the works of light, then we are in communion with Him, but if we do not do them, then we are strangers to Him. And how is He not the true light and completely sinless, when He "was numbered with the transgressors" for your sake (Isa. 53:12)? So then, if we, who once cried out: "His blood be on us and on our children" (Matt. 27:25), shamelessly say that we have not sinned, then we "deceive ourselves," as though crucifying Christ were no sin. The Apostle did not say: we lie, but: we deceive ourselves, because deception is outside of truth. But if we acknowledge our sin and confess it, He will forgive us.
GK Chestertonon 1 John 1:8AD 1936
We have grown to associate morality in a book with a kind of optimism and prettiness; according to us, a moral book is a book about moral people. But the old idea was almost exactly the opposite; a moral book was a book about immoral people. ... Telling the truth about the terrible struggle of the human soul is surely a very elementary part of the ethics of honesty. If the characters are not wicked, the book is.

If we are beginners in the Christian life we have nothing to make the fatal flaw clear to ourselves. Does the person with a smelly breath know it smells? Or does the Club bore know he is a bore? Is there a single man or woman who believes himself or herself to be a bore or temperamentally jealous? Yet the world is pretty well sprinkled with bores and jealous people. If we are like that, everyone else will know it before we do. You ask why your friends have not told you about it. But what if they have? They may have tried again and again; but on every occasion, we thought they were being queer, that they were in a bad temper, or simply mistaken. They have tried again and again, and have probably now given it up.

What should be done about it? What is the good of my talking about the fatal flaw if one does not know about it? I think the first step is to get down to the flaws which one does know. I am speaking to Christians. Many of you, no doubt, are very far ahead of me in the Christian way. It is not for me to decide whether you should confess your sins to a priest or not (our Prayer Book leaves that free to all and demands it of none) but if you do not, you should at least make a list on a piece of paper, and make a serious act of penance about each one of them. There is something about the mere words, you know, provided you avoid two dangers, either of sensational exaggeration — trying to work things up and make melodramatic sins out of small matters — or the opposite danger of slurring things over. It is essential to use the plain, simple, old-fashioned words that you would use about anyone else. I mean words like theft, or fornication, or hatred, instead of 'I did not mean to be dishonest,' or 'I was only a boy then,' or 'I lost my temper.' I think that this steady facing of what one does know and bringing it before God, without excuses, and seriously asking for Forgiveness and Grace, and resolving as far as in one lies to do better, is the only way in which we can ever begin to know the fatal thing which is always there, and preventing us from becoming perfectly just to our wife or husband, or being a better employer or employee.

It is no good passing this over with some vague, general admission such as "Of course, I know I have my faults." It is important to realize that there is some really fatal flaw in you: something which gives the others just that same feeling of despair which their flaws give you. And it is almost certainly something you don't know about—like what the advertisements call "halitosis," which everyone notices except the person who has it. But why, you ask, don't the others tell me? Believe me, they have tried to tell you over and over again, and you just couldn't "take it." Perhaps a good deal of what you call their "nagging" or "bad temper" or "queerness" are just their attempts to make you see the truth. And even the faults you do know you don't know fully. You say, "I admit I lost my temper last night"; but the others know that you're always doing it, that you are a bad-tempered person. You say, "I admit I drank too much last Saturday"; but every one else knows that you are an habitual drunkard.

The essential act of mercy was to pardon; and pardon in its very essence involves the recognition of guilt and ill-desert in the recipient. If crime is only a disease which needs cure, not sin which deserves punishment, it cannot be pardoned. How can you pardon a man for having a gumboil or a club foot?
Source: THE HUMANITARIAN THEORY OF PUNISHMENT, from God in the Dock
CS Lewison 1 John 1:8-9AD 1963
The demand that God should forgive such a man while he remains what he is, is based on a confusion between condoning and forgiving. To condone an evil is simply to ignore it, to treat it as if it were good. But forgiveness needs to be accepted as well as offered if it is to be complete: and a man who admits no guilt can accept no forgiveness.
