1 John 1:9

From the Epistle also of John they forthwith cull (a proof). It is said: “The blood of His Son purifieth us utterly from every sin.” Always then, and in every form, we will sin, if always and from every sin He utterly purifies us; or else, if not always , not again after believing; and if not from sin, not again from fornication. But what is the point whence (John) has started? He had predicated “God” to be “Light,” and that “darkness is not in Him,” and that “we lie if we say that we have communion with Him, and walk in darkness.” “If, however,” he says, “we walk in the light, we shall have communion with Him, and the blood of Jesus Christ our Lord purifieth us utterly from every sin.” Walking, then, in the light, do we sin? and, sinning in the light, shall we be utterly purified? By no means. For he who sins is not in the light, but in darkness. …

39. But in this life, when the corruptible body presseth down the soul, if their Church is already of such a character as they maintain, they would not utter unto God the prayer which our Lord has taught us to employ: "Forgive us our debts." For since all sins have been remitted in baptism, why does the Church make this petition, if already, even in this life, it has neither spot nor wrinkle, nor any such thing? They would also have a fight to despise the warning of the Apostle John, when he cries out in his epistle, "If we say that we have no sin, we deceive ourselves, and the truth is not in us. …

3. According to a certain respect then they were evil, who after another respect were good. For to them to whom it is said, “Ye being evil know how to give good gifts unto your children;” is added immediately, “How much more shall your Father which is in heaven?” He is then the Father of the evil, but not of those who are to be left so; because He is the Physician of them who are to be cured. According to a certain sort then they were evil. And yet those guests of the Householder at the King’s marriage, were not I suppose of that number of whom it was said, “they invited good and bad,” that they should be reckoned among the number of the bad, who we have heard were shut out in his person who was found not to have a wedding garment. According to a certain respect, I repeat they were bad, who yet were good; and according to a certain respect they were good, who yet were bad. …

4. This would I say even if thou hadst no sin which thou mightest desire to be forgiven thee. But as it is, whosoever thou art, thou art a man; though thou be righteous, thou art a man; be thou layman, or monk, or clerk, or Bishop, or Apostle, thou art a man. Hear the Apostle’s voice, “If we shall say that we have no sin, we deceive ourselves.” He, that famous John and an Evangelist, he whom the Lord Christ loved beyond all the rest, who lay on His breast, he says, “If we shall say.” He did not say, “If ye shall say that ye have no sin,” but “if we shall say that we have no sin, we deceive ourselves, and the truth is not in us.” He joined himself in the guilt, that he might be joined in the pardon also. “If we shall say.” Consider who it is that says, “If we shall say that we have no sin, we deceive ourselves, and the truth is not in us. …

8. But what shall I say? Peradventure when they learnt the prayer, they were still weak. Some one, perhaps, will say this. When the Lord Jesus taught them that prayer, they were yet babes, weak, carnal; they were not yet spiritual, who have no sin. What then, Brethren? When they became spiritual, did they cease to pray? Then Christ ought to have said, “Pray in such wise now;” and to have given them, when spiritual, another prayer. It is one and the same. He who gave it is One and the Same; use it then in prayer in the Church. But we will take away all controversy, when you say the Holy Apostles were spiritual, up to the time of the Lord’s Passion they were carnal; this you must say. And indeed, the truth is, as He was hanging, they were in alarm, and the Apostles then despaired when the robber believed. …

4. But what is this? what does it mean? and what is there in it we need to examine? The Lord says, The Truth declares that even he who has been washed has need still to wash his feet. What, my brethren, what think you of it, save that in holy baptism a man has all of him washed, not all save his feet, but every whit; and yet, while thereafter living in this human state, he cannot fail to tread on the ground with his feet. And thus our human feelings themselves, which are inseparable from our mortal life on earth, are like feet wherewith we are brought into sensible contact with human affairs; and are so in such a way, that if we say we have no sin, we deceive ourselves, and the truth is not in us. …

6. For see what He saith; “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. For see what follows: “If we confess our sins, He is faithful and just to forgive us our sins, and to purge us from all iniquity.” Not only the past, but haply if we have contracted any from this life; because a man, so long as he bears the flesh, cannot but have some at any rate light sins. But these which we call light, do not thou make light of. If thou make light of them when thou weighest them, be afraid when thou countest them. …

3. It is written, and is read, and is true, in this Psalm, that “They who do wickedness, walk not in His ways” ( ver. 3 ). But we must endeavour, with the help of God, “in” whose “hand are both we and our words,” that what is rightly said, by not being rightly understood, may not confuse the reader or hearer. For we must beware, lest all the Saints, whose words these are, “If we say that we have no sin, we deceive ourselves, and the truth is not in us;” may either not be thought to walk in the ways of the Lord, since sin is wickedness, and “they who do wickedness, walk not in His ways;” or, because it is not doubtful that they walk in the ways of the Lord, may be thought to have no sin, which is beyond doubt false. For it is not said merely for the sake of avoiding arrogance and pride. …

A. I will requite like with like, and will show that, according to you, the little epistle of the Evangelist contradicts itself. For, if whosoever is begotten of God sinneth not because His seed abideth in him, and he cannot sin, because he is born of God, how is it that the writer says in the same place:“If we say that we have no sin, we deceive ourselves, and the truth is not in us?” You cannot explain. You hesitate and are confused. Listen to the same Evangelist telling us that“If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.” We are then righteous when we confess that we are sinners, and our righteousness depends not upon our own merits, but on the mercy of God, as the Holy Scripture says,“The righteous man accuseth himself when he beginneth to speak,” and elsewhere,“Tell thy sins that thou mayest be justified.”“God h …

6. See, I pray thee, how great a dignity Jesus bestows on thee. Thou wert called a Catechumen, while the word echoed round thee from without; hearing of hope, and knowing it not; hearing mysteries, and not understanding them; hearing Scriptures, and not knowing their depth. The echo is no longer around thee, but within thee; for the indwelling Spirit henceforth makes thy mind a house of God. When thou shalt have heard what is written concerning the mysteries, then wilt thou understand things which thou knewest not. And think not that thou receivest a small thing: though a miserable man, thou receivest one of God’s titles. Hear St. Paul saying, God is faithful . Hear another Scripture saying, God is faithful and just . Foreseeing this, the Psalmist, because men are to receive a title of God, spoke thus in the person of God: I said, Ye are Gods, and are all sons of the Most High . …
