1 Having therefore these promises, dearly beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God. 2 Receive us; we have wronged no man, we have corrupted no man, we have defrauded no man. 3 I speak not this to condemn you: for I have said before, that ye are in our hearts to die and live with you. 4 Great is my boldness of speech toward you, great is my glorying of you: I am filled with comfort, I am exceeding joyful in all our tribulation. 5 For, when we were come into Macedonia, our flesh had no rest, but we were troubled on every side; without were fightings, within were fears. 6 Nevertheless God, that comforteth those that are cast down, comforted us by the coming of Titus; 7 And not by his coming only, but by the consolation wherewith he was comforted in you, when he told us your earnest desire, your mourning, your fervent mind toward me; so that I rejoiced the more. 8 For though I made you sorry with a letter, I do not repent, though I did repent: for I perceive that the same epistle hath made you sorry, though it were but for a season. 9 Now I rejoice, not that ye were made sorry, but that ye sorrowed to repentance: for ye were made sorry after a godly manner, that ye might receive damage by us in nothing. 10 For godly sorrow worketh repentance to salvation not to be repented of: but the sorrow of the world worketh death. 11 For behold this selfsame thing, that ye sorrowed after a godly sort, what carefulness it wrought in you, yea, what clearing of yourselves, yea, what indignation, yea, what fear, yea, what vehement desire, yea, what zeal, yea, what revenge! In all things ye have approved yourselves to be clear in this matter. 12 Wherefore, though I wrote unto you, I did it not for his cause that had done the wrong, nor for his cause that suffered wrong, but that our care for you in the sight of God might appear unto you. 13 Therefore we were comforted in your comfort: yea, and exceedingly the more joyed we for the joy of Titus, because his spirit was refreshed by you all. 14 For if I have boasted any thing to him of you, I am not ashamed; but as we spake all things to you in truth, even so our boasting, which I made before Titus, is found a truth. 15 And his inward affection is more abundant toward you, whilst he remembereth the obedience of you all, how with fear and trembling ye received him. 16 I rejoice therefore that I have confidence in you in all things.
[AD 215] Clement of Alexandria on 2 Corinthians 7:1
Hence Paul speaks against people who are like those I have mentioned, saying: "You have then these promises, beloved; let us cleanse ourselves from all defilement of flesh and spirit, perfecting holiness in the fear of God."

[AD 220] Tertullian on 2 Corinthians 7:1
When also he (in a later passage) enjoins us "to cleanse ourselves from all filthiness of flesh and blood" (since this substance enters not the kingdom of Gods ); when, again, he "espouses the church as a chaste virgin to Christ," a spouse to a spouse in very deed, an image cannot be combined and compared with what is opposed to the real nature the thing (with which it is compared).

[AD 220] Tertullian on 2 Corinthians 7:1
' This (thread of discourse) also you spin out, O apostle, when at the very moment you yourself are offering your hand to so huge a whirlpool of impurities; nay, you superadd yet further, 'Having therefore this promise, beloved, cleanse we ourselves out from every defilement of flesh and spirit, perfecting chastity in God's fear.'" I pray you, had he who fixes such (exhortations) in our minds been recalling some notorious fornicator into the Church? or is his reason for writing it, to prevent himself from appearing to you in the present day to have so recalled him? These (words of his) will be in duty bound alike to serve as a prescriptive rule for the foregone, and a prejudgment for the following, (parts of the Epistle).

[AD 379] Basil of Caesarea on 2 Corinthians 7:1
Here we are instructed to marvel at the unspeakable benevolence of God in Christ Jesus and with the greater fear to cleanse ourselves of every defilement of the flesh and the spirit.

[AD 380] Apostolic Constitutions on 2 Corinthians 7:1
Let him that offers himself to baptism learn these and the like things during the time that he is a catechumen; and let him who lays his hands upon him adore God, the Lord of the whole world, and thank Him for His creation, for His sending Christ His only begotten Son, that He might save man by blot-ring out his transgressions, and that He might remit ungodliness and sins, and might "purify him from all filthiness of flesh and spirit".
Es in His law day and night; strengthen them in piety, unite them to and number them with His holy flock; vouchsafe them the layer of regeneration, and the garment of in corruption, which is the true life; and deliver them from all ungodliness, and give no place to the adversary against them; "and cleanse them from all filthiness of flesh and spirit, and dwell in them, and walk in them, by His Christ; bless their goings out and their comings in, and order their affairs for their good.".
cleanse them from all filthiness of flesh and spirit.
And let the bishop say: O God, who art great, and whose name is great, who art great in counsel and mighty in works, the God and Father of Thy holy child Jesus, our Saviour; look down upon us, and upon this Thy flock, which Thou hast chosen by Him to the glory of Thy name; and sanctify our body and soul, and grant us the favour to be "made pure from all filthiness of flesh and spirit".
who didst not disdain that Thy only begotten Son should be born of a woman; who also in the tabernacle of the testimony, and in the temple, didst ordain women to be keepers of Thy holy gates,-do Thou now also look down upon this Thy servant, who is to be ordained to the office of a deaconess, and grant her Thy Holy Spirit, and "cleanse her from all filthiness of flesh and spirit"

[AD 384] Ambrosiaster on 2 Corinthians 7:1
What Paul is saying is clear, but “defilement of the flesh” is to be interpreted in a complex way. Notice that he did not say “from defilement of the flesh” but “from every defilement of the flesh” in order to encourage us to flee from all carnal vices—everything which the law prohibits—so that we might perfect holiness of the Spirit in the fear of God. We do this by pursuing the things which are right in the fear of God and which are therefore holy, abstaining from sins in the name of Christ. People who restrain themselves from vices without professing Christ may seem to be set apart according to the world but not according to the Spirit of God. Only those who believe are made clean. Others, whatever they may be like, remain unclean.

[AD 407] John Chrysostom on 2 Corinthians 7:1
"Having therefore these promises, beloved."

What promises? That we should be temples of God, sons and daughters, have Him indwelling, and walking in us, be His people, have Him for our God and Father.

"Let us cleanse ourselves from all defilement of flesh and spirit."

Let us neither touch unclean things, for this is cleansing of the flesh; nor things which defile the soul, for this is cleansing of the spirit. Yet he is not content with this only, but adds also,

"Perfecting holiness in the fear of God." For not to touch the unclean thing doth not make clean, but there needeth something else besides to our becoming holy; earnestness, heedfulness, piety. And he well said, "In the fear of God." For it is possible to perfect chasteness, not in the fear of God but for vainglory. And along with this he implies yet another thing, by saying, "In the fear of God;" the manner, namely, whereafter holiness may be perfected. For if lust be even an imperious thing, still if thou occupy its territory with the fear of God, thou hast stayed its frenzy.

Now by holiness here he means not chastity alone, but the freedom from every kind of sin, for he is holy that is pure. Now one will become pure, not if he be free from fornication only, but if from covetousness also, and envy, and pride, and vainglory, yea especially from vainglory which in every thing indeed it behoveth to avoid, but much more in alms-giving; since neither will it be almsgiving, if it have this distemper, but display and cruelty.

[AD 458] Theodoret of Cyrus on 2 Corinthians 7:1
Paul uses the word spirit in this verse to mean “soul.”

[AD 202] Irenaeus on 2 Corinthians 7:2
"We have injured no man, corrupted no man, circumvented no man."

[AD 384] Ambrosiaster on 2 Corinthians 7:2
Paul wants the Corinthians to give thought to what he is saying, so that when they have taken it to heart they may conclude that what he is saying is true.

[AD 407] John Chrysostom on 2 Corinthians 7:2
Again he raiseth the discourse about love, mitigating the harshness of his rebuke. For since he had convicted and reproached them as being beloved indeed, yet not loving in an equal degree, but breaking away from his love and mixing up with other pestilent fellows; again he softens the vehemence of his rebuke, saying, "Make room for us," that is, "love us;" and prays to receive a favor involving no burden, and advantaging them that confer above them that receive it. And he said not, 'love,' but with a stronger appeal to their pity, "make room for." 'Who expelled us?' saith he: 'Who cast us out of your hearts? How come we to be straitened in you?' for since he said above, "Ye are straitened in your affections;" here declaring it more clearly, he said, "make room for us:" in this way also again winning them to himself. For nothing doth so produce love as for the beloved to know that he that loveth him exceedingly desireth his love.

"We wronged no man." See how again he does not mention the benefits done by him, but frameth his speech in another way, so as to be both less offensive and more cutting. And at the same time he also alludes to the false apostles, saying, "We wronged no man, we corrupted no man, we defrauded no man."

What is "we corrupted?" That is, we beguiled no man; as he says elsewhere also. "Lest by any means, as the serpent beguiled Eve, so your minds should be corrupted." (2 Corinthians 11:3)

"We defrauded no man;" we plundered, plotted against no man. And he for the present forbears to say, 'we benefited you in such and such ways;' but framing his language so as more to shame them, "We wronged no man," he says; as much as saying, 'Even had we in no wise benefited you, not even so ought ye to turn away from us; for ye have nothing to lay to our charge, either small or great.'

[AD 384] Ambrosiaster on 2 Corinthians 7:3
Paul wants them to realize in what frame of mind he is speaking to them. He is certainly not rejecting people whom he wants to have as sharers with him, but he is exhorting them to make themselves worthy of this sharing.

[AD 407] John Chrysostom on 2 Corinthians 7:3
"I say it not to condemn you." How is this evident? "For I have said before," he adds, "that ye are in our hearts to die and live with you." This is the greatest affection, when even though treated with contempt, he chooseth both to die and live with them. 'For neither are ye merely in our hearts,' he says, 'but in such sort as I said. For it is possible both to love and to shun dangers, but we do not thus.' And behold here also wisdom unspeakable. For he spake not of what had been done for them, that he might not seem to be again reproaching them, but he promiseth for the future. 'For should it chance,' saith he, 'that danger should invade, for your sakes I am ready to suffer every thing; and neither death nor life seemeth aught to me in itself, but in whichever ye be, that is to me more desirable, both death than life and life than death.' Howbeit, dying indeed is manifestly a proof of love; but living, who is there that would not choose, even of those who are not friends? Why then does the Apostle mention it as something great? Because it is even exceeding great. For numbers indeed sympathize with their friends when they are in misfortune, but when they are in honor rejoice not with, but envy, them. 'But not so we; but whether ye be in calamity, we are not afraid to share your ill fortune; or whether ye be prosperous, we are not wounded with envy.'

[AD 311] Methodius of Olympus on 2 Corinthians 7:4
Let the earth also cause compassion to spring up to its inhabitants; for I am filled with comfort; I am exceeding joyful since I have seen Thee, the Saviour of men.

[AD 384] Ambrosiaster on 2 Corinthians 7:4
Paul is confident because of the way the Corinthians responded to his reproof in the first letter. The fact that they did not take it badly has given him the confidence to admonish them again. He also says that he has been consoled by this to such an extent that in spite of all his affliction he is overflowing with joy. Seeing that there is hope for the people on whose behalf he is enduring hardships, he is rejoicing in spite of his tribulations, being certain that he will please God for the fact that they have received salvation.

[AD 407] John Chrysostom on 2 Corinthians 7:4
"Great is my boldness of speech towards you." 'Therefore I venture upon such things,' he says, 'not to condemn you by what I say, but out of my great boldness of speech,' which also farther signifying, he said, "Great is my glorying on your behalf." 'For think not indeed,' he saith, 'that because I thus speak, I speak as though I had condemned you altogether; (for I am exceedingly proud of, and glory in, you;) but both out of tender concern and a desire that you should make greater increase unto virtue.' And so he said to the Hebrews also after much rebuke; "But we are persuaded better things of you, and things that accompany salvation, though we thus speak: and we desire that each one of you may show the same diligence to the fullness of hope even to the end." (Hebrews 6:9, 11) So indeed here also, "Great is my glorying on your behalf." 'We glory to others of you,' he says. Seest thou what genuine comfort he has given? 'And,' he saith, 'I do not simply glory, but also, greatly.' Accordingly he added these words; "I am filled with comfort." What comfort? 'That coming from you; because that ye, having been reformed, comforted me by your conduct.' This is the test of one that loveth, both to complain of not being loved and to fear lest he should inflict pain by complaining immoderately. Therefore he says, "I am filled with comfort, I overflow with joy." 'But these expressions,' saith one, 'seem to contradict the former.' They do not do so, however, but are even exceedingly in harmony with them. For these procure for the former a favorable reception; and the praise which they convey makes the benefit of those rebukes more genuine, by quietly abstracting what was painful in them. Wherefore he uses these expressions, but with great genuineness and earnestness. For he did not say, 'I am filled with joy;' but, "I abound;" or rather, not "abound" either, but "super-abound;" in this way also again showing his yearning, that even though he be so loved as to rejoice and exult, he does not yet think himself loved as he ought to be loved, nor to have received full payment; so insatiable was he out of his exceeding love of them. For the joy it brings to be loved in any degree by those one passionately loves, is great by reason of our loving them exceedingly. So that this again was a proof of his affection. And of the comfort indeed, he saith, 'I am filled;' 'I have received what was owing to me;' but of the joy, "I superabound;" that is, 'I was desponding about you; but ye have sufficiently excused yourselves and supplied comfort: for ye have not only removed the ground of my sorrow, but have even increased joy.' Then showing its greatness, he not only declares it by saying, 'I superabound in joy," but also by adding, "in all our affliction." 'For so great was the delight arising to us on your account that it was not even dimmed by so great tribulation, but through the excess of its own greatness it overcame the sorrows that had hold of us, and suffered us not to feel the sense of them.'

[AD 220] Tertullian on 2 Corinthians 7:5
Accordingly, when he is going to assign afflictions to the flesh as its especial liability-according to the statement he had already made-he says, "When we were come into Macedonia, our flesh had no rest; " then, in order to make the soul a fellow-sufferer with the body, he adds, "We were troubled on every side; without were fightings," which of course warred down the flesh, "within were fears," which afflicted the soul.

[AD 384] Ambrosiaster on 2 Corinthians 7:5
It is because the flesh is irrational that Paul says that it has no rest from its suffering. But the soul, although it was suffering in the body, did have rest. This is because of the hope that God would reward them for the tribulations inflicted on them by unbelievers. Fightings were inflicted on the body, and fears attacked the soul, but Paul was not at all afflicted in the Spirit, who was given to him so that he might endure such things.

[AD 407] John Chrysostom on 2 Corinthians 7:5
"For even when we were come into Macedonia, our flesh had no relief."

For since he said, "our tribulation;" he both explains of what sort it was, and magnifies it by his words, in order to show that the consolation and joys received from them was great, seeing it had repelled so great a sorrow. "But we were afflicted on every side."

How on every side? for "without were fightings," from the unbelievers; "within were fears;" because of the weak among the believers, lest they should be drawn aside. For not amongst the Corinthians only did these things happen, but elsewhere also.

[AD 458] Theodoret of Cyrus on 2 Corinthians 7:5
Paul had to do battle not only with external foes but also with enemies within the fellowship of the church. He was afraid that believers would be turned away to harmful things.

[AD 384] Ambrosiaster on 2 Corinthians 7:6
It is always a great comfort, when we are suffering, to have someone near us who can share it with us.

[AD 407] John Chrysostom on 2 Corinthians 7:6
"Nevertheless He that comforteth the lowly comforted us by the coming of Titus."

For since he had testified great things of them in what he said, that he may not seem to be flattering them he cites as witness Titus the brother, who had come from them to Paul after the first Epistle to declare unto him the particulars of their amendment. But consider, I pray you, how in every place he maketh a great matter of the coming of Titus. For he saith also before, "Furthermore when I came to Troas for the Gospel, I had no relief for my spirit because I found not Titus my brother;" (2 Corinthians 2:12-13) and in this place again "we were comforted," he saith, "by the coming of Titus." For he is desirous also of establishing the man in their confidence and of making him exceedingly dear to them. And observe how he provides for both these things. For by saying on the one hand, "I had no relief for my spirit," he showeth the greatness of his virtue; and by saying on the other, that, in our tribulation his coming sufficed unto comfort; yet "not by his coming only, but also by the comfort wherewith he was comforted in you," he endeareth the man unto the Corinthians. For nothing doth so produce and cement friendships as the saying something sound and favorable of any one. And such he testifies Titus did; when he says that 'by his coming he hath given us wings with pleasure; such things did he report of you. On this ground his coming made us glad. For we were delighted not only by his coming, but also for the comfort wherewith he was comforted in you.' And how was he comforted? By your virtue, by your good deeds.

[AD 384] Ambrosiaster on 2 Corinthians 7:7
Paul showed what great affection he had for them. He paid no mind to the stench of the dungeon, nor of the pain of the lashes, nor of the rope with which his feet were bound. But when he heard that the Corinthians had amended their ways he rejoiced, and forgetting his sufferings, thanked God for their salvation, viewing it as a kind of reward for his troubles.

[AD 407] John Chrysostom on 2 Corinthians 7:7
"While he told us your longing, your mourning, your zeal for me." 'These things made him glad,' he says, 'these things comforted him.' Seest thou how he shows that he also is an earnest lover of theirs, seeing he considers their good report as a consolation to himself; and when he was come, gloried, as though on account of his own good things, unto Paul.

And observe with what warmth of expression he reporteth these things, "Your longing, your mourning, your zeal." For it was likely that they would mourn and grieve why the blessed Paul was so much displeased, why he had kept away from them so long. And therefore he did not say simply tears, but "mourning;" nor desire, but "longing;" nor anger, but "zeal;" and again "zeal toward him," which they displayed both about him that had committed fornication and about those who were accusing him. 'For,' saith he, 'ye were inflamed and blazed out on receiving my letters.' On these accounts he abounds in joy, on these accounts he is filled with consolation, because he made them feel. It seems to me, however, that these things are said not only to soften what has gone before, but also in encouragement of those who had acted in these things virtuously. For although I suppose that some were obnoxious to those former accusations and unworthy of these praises; nevertheless, he doth not distinguish them, but makes both the praises and the accusations common, leaving it to the conscience of his hearers to select that which belongs to them. For so both the one would be void of offence, and the other lead them on to much fervor of mind.

[AD 407] John Chrysostom on 2 Corinthians 7:8-9
Having said, "I do not regret," he tells the reason also; alleging the good that resulted from his letter; and skillfully excusing himself by saying, "though but for a season." For truly that which was painful was brief, but that which was profitable was perpetual. And what indeed followed naturally was to say, 'even though it grieved you for a season, yet it made you glad and benefited you forever.' But he doth not say this: but before mentioning the gain he passes again to his praises of them, and the proof of his own concern for them, saying, "Now I rejoice, not that ye were made sorry," ('for what gain came to me from you being made sorry?) "but that ye were made sorry unto repentance," that the sorrow brought some gain.' For a father also when he sees his son under the knife rejoiceth not that he is being pained, but that he is being cured; so also doth this man. But observe how he transfers all that was well achieved in the matter unto themselves; and lays whatever was painful to the account of the Epistle, saying, "It made you sorry for a season;" whilst the benefit that resulted from it he speaks of as their own good achieving. For he said not, 'The Epistle corrected you,' although this was the case; but, "ye sorrowed unto repentance."

[AD 407] John Chrysostom on 2 Corinthians 7:8
He goes on to apologize for his Epistle, when, (the sin having been corrected,) to treat them tenderly was unattended with danger; and he shows the advantage of the thing. For he did this indeed even before, when he said, "For out of much affliction and anguish of heart, I wrote unto you: not that ye should be made sorry, but that ye might know the love which I have toward you." And he does it also now, establishing this same point in more words. And he said not, 'I regretted indeed before, but now I do not regret:' but how? "I regret not now, though I did regret." 'Even if what I wrote,' he says, 'was such as to overstep the [due] measure of rebuke, and to cause me to regret; still the great advantage which has accrued from them doth not allow me to regret.' And this he said, not as though he had rebuked them beyond due measure, but to heighten his praises of them. 'For the amendment ye manifested was so great,' saith he, 'that even if I did happen to smite you too severely insomuch that I even condemned myself, I praise myself now from the result.' Just as with little children, when they have undergone a painful remedy, such as an incision, or cautery, or bitter physic, afterwards we are not afraid to sooth them; so also doth Paul.

[AD 430] Augustine of Hippo on 2 Corinthians 7:8
Moreover, even sorrow, the emotion for which, the Stoics claim, there can be found in the soul of a wise man no corresponding “attitude,” is a word used in a good sense, especially in Christian writings. The apostle, for example, praises the Corinthians because they were sorrowful according to God. Of course, someone may object that the apostle congratulated the Corinthians because their sorrow led them to repentance and that such sorrow can be experienced only by those who have sinned. What he says is this: “Seeing that the same letter did for a while make you sorry, now I am glad; not because you were made sorry but because your sorrow led you to repentance. For you were made sorry according to God, that you might suffer no loss at our hands. For the sorrow that is according to God produces repentance that surely tends to salvation, whereas the sorrow that is according to the world produces death. For behold this very fact that you were made sorry according to God, what earnestness it has wrought in you.”

[AD 397] Ambrose of Milan on 2 Corinthians 7:9
Hence Paul teaches us that that kind of sorrow is of value which has not this world but God as its end. It is right, he says, that you become sorrowful, so as to feel repentance in the face of God.… Take note of those who in the Old Testament were sorrowful in the midst of their bodily labors and who attained grace, while those who found delight in such pleasures continued to be punished. Hence the Hebrews, who groaned in the works of Egypt, attained the grace of the just and those “who ate bread with mourning and fear” were supplied with spiritual good.22.

[AD 407] John Chrysostom on 2 Corinthians 7:9
Seest thou wisdom unspeakable? 'For had we not done this,' he says, 'we had done you damage.' And he affirms that indeed which was well achieved to be theirs, but the damage his own, if indeed he had been silent. For if they are likely to be corrected by a sharp rebuke, then, if we did not sharply rebuke, we should have done you damage; and the injury would not be with you alone, but also with us. For just as he that gives not to the merchant what is necessary for his voyage, he it is that causeth the damage; so also we, if we did not offer you that occasion of repentance, should have wrought you damage. Seest thou that the not rebuking those that sin is a damage both to the master and to the disciple?

[AD 160] Shepherd of Hermas on 2 Corinthians 7:10
This grief, then, appears to be accompanied by salvation, because the man, after having done a wicked deed, repented. Both actions grieve the Spirit: doubt, because it did not accomplish its object; and anger grieves the Spirit, because it did what was wicked.

[AD 258] Cyprian on 2 Corinthians 7:10
That all sins may be forgiven him who has turned to God with his whole heart... Also in the second Epistle of the blessed Paul to the Corinthians: "For the sorrow which is according to God worketh a stedfast repentance unto salvation, but the sorrow of the world worketh death."

[AD 384] Ambrosiaster on 2 Corinthians 7:10
Godly grief brings about the death of worldliness. When the sinner is found out he is grieved because he is bound to be punished, not having anyone from whom he may expect mercy. Perhaps for the moment there may be nobody who can exact retribution from him, but he knows he will not be able to escape the judgment of God.

[AD 407] John Chrysostom on 2 Corinthians 7:10
However, I marvel how God, who from the beginning gave humanity pain, which came from sin, abolishes his decision with one resolution and expels the judgment with the sentence. And hear how. Sin produced pain, and through pain sin is annihilated. Pay attention carefully. God threatens the woman. He brings upon her the punishment for her disobedience, and he tells her: “You shall bring forth children in pain.” And he showed pain as the harvest of sin. However, oh, how munificent he is! That which he gave for punishment he changed to salvation. Sin gave birth to pain; pain destroys sin. Just as a worm that is born by a tree consumes the very same tree, likewise pain, which is born by sin, kills sin when it is supplied by repentance. For this reason Paul says: “Godly pain produces a repentance that leads to salvation and brings no regret.” Pain is good for those who repent sincerely; the sorrow, matching the sin, suits those who sin.… Mourn for the sin so you may not lament for the punishment. Apologize to the judge before you come to the court. Or do you not know that all who want to sin flatter the judge, not when the case is being tried but before they enter the court, or through friends, or through guardians, or through another way they coax the judge? The same with God: you cannot persuade the Judge during the time of the tribunal. It is possible for you to plead with the Judge before the time of judgment.

[AD 407] John Chrysostom on 2 Corinthians 7:10
'Therefore.' he says, 'though I did regret before I saw the fruit and the gain, how great they were I do not regret now.' For such a thing is godly sorrow. And then he philosophizeth about it, showing that sorrow is not in all cases a grievous thing, but when it is worldly. And what is worldly? If thou be in sorrow for money, for reputation, for him that is departed, all these are worldly. Wherefore also they work death. For he that is in sorrow for reputation's sake feeleth envy and is driven oftentimes to perish: such sorrow was that which Cain sorrowed, such Esau. By this worldly sorrow then he meaneth that which is to the harm of those that sorrow. For only in respect to sins is sorrow a profitable thing; as is evident in this way. He that sorroweth for loss of wealth repaireth not that damage; he that sorroweth for one deceased raiseth not the dead to life again; he that sorroweth for a sickness, not only is not made well but even aggravates the disease: he that sorroweth for sins, he alone attains some advantage from his sorrow, for he maketh his sins wane and disappear. For since the medicine has been prepared for this thing, in this case only is it potent and displays its profitableness; and in the other cases is even injurious. 'And yet Cain,' saith one, 'sorrowed because he was not accepted with God.' It was not for this, but because he saw his brother glorious in honor; for had he grieved for this, it behoved him to emulate and rejoice with him; but, as it was, grieving, he showed that his was a worldly sorrow. But not so did David, nor Peter, nor any of the righteous. Wherefore they were accepted, when grieving either over their own sins or those of others. And yet what is more oppressive than sorrow? Still when it is after a godly sort, it is better than the joy in the world. For this indeed ends in nothing; but that "worketh repentance unto salvation, a salvation that bringeth no regret." For what is admirable in it is this that one who had thus sorrowed would never repent, whilst this is an especial characteristic of worldly sorrow. For what is more regretted than a true born son? And what is a heavier grief than a death of this sort? But yet those fathers who in the height of their grief culture nobody and who wildly beat themselves, after a time repent because they have grieved immoderately; as having thereby nothing benefitted themselves, but even added to their affliction. But not such as this is godly sorrow; but it possesseth two advantages, that of not being condemned in that a man grieves for, and that this sorrow endeth in salvation; of both which that is deprived. For they both sorrow unto harm and after they have sorrowed vehemently condemn themselves, bringing forth this greatest token of having done it unto harm. But godly sorrow is the reverse [of this]: wherefore also he said, "worketh repentance unto salvation, a repentance that bringeth no regret." For no one will condemn himself if he have sorrowed for sin, if he have mourned and afflicted himself.

[AD 430] Augustine of Hippo on 2 Corinthians 7:10
And, in another passage, he says: “The sorrow that is according to God produces repentance that tends to salvation of which one does not repent.” He who is sad according to God is sad in repentance for his sins; sorrow because of one’s own iniquity produces justice. First, let what you are displease you so that you may be able to be what you are not. “The sadness that is according to God produces repentance that tends to salvation of which one does not repent.” He says: “repentance that tends to salvation.” What sort of salvation? That of which one does not repent. What does that mean? One of which you do not repent at any time. For we have had a life of which we ought to have repented; we have had a life calculated to inspire repentance. But we cannot come to that life of which one does not repent except through repentance for an evil life. Will you, my brothers, as I had begun to say, ever find dung in a sifted mass of wheat? Nevertheless, the wheat arrives at that luster, at that fine and beautiful appearance, by means of dung; the foulness was the path to a beautiful result.

[AD 430] Augustine of Hippo on 2 Corinthians 7:10
Therefore, my brothers, as I have said before, a suitable place for dung helps to produce fruit, but an unsuitable place leads to uncleanness. Someone or other has said, I have come upon this sad person; I see the dung; I examine the place. Tell me, my friend, why are you sad? He says: I have lost my money. The place is unclean; there is no fruit. Let him hear the apostle: “The sorrow that is according to the world produces death.” I have looked at still another person groaning, weeping and praying; I recognize the dung and I examine the place. Moreover, I have directed my ear to this man’s prayer, and I have heard him say: “O Lord, be thou merciful to me: heal my soul, for I have sinned against you.” He laments his sin; I recognize the field; I look for fruit. Thanks be to God! The dung is in a good place; it is not useless there; it produces fruit. This is truly the time of fruitful sorrow, so that we may lament the state of our mortality, the abundance of temptations, the stealthy attacks of sinners, the clash of desires, the conflicts of passions ever rebelling against good thoughts. On this account let us grieve; let us be sad because of this state of affairs.

[AD 500] Desert Fathers on 2 Corinthians 7:10
[Syncletica] also said, ‘There is a useful sorrow, and a destructive sorrow. Sorrow is useful when we weep for our sins, and for our neighbour’s ignorance, and so that we may not relax our purpose to attain to true goodness, these are the real kinds of sorrow. Our enemy adds something to this. For he sends sorrow without reason, which is something called lethargy. We ought always to drive out a sadness like that with prayers and psalms.’

[AD 379] Basil of Caesarea on 2 Corinthians 7:11
One who provokes godly grief in us is our benefactor.

[AD 384] Ambrosiaster on 2 Corinthians 7:11
Someone who repents is troubled by the fear that he might sin again. But a person who knows that he has been deformed by sin longs to reform himself. One who knows that he is being rebuked for his own good begins to experience a zeal for bringing good works to completion.

[AD 407] John Chrysostom on 2 Corinthians 7:11
"For behold," he saith, "this self-same thing, that ye were made sorry after a godly sort, what earnest care it wrought in you." 'For not only,' he saith, 'did your sorrow not cast you into that condemning of yourselves, as having acted idly in so doing; but it made you even more careful.' Then he speaks of the certain tokens of that carefulness; "Yea," what "clearing of yourselves," towards me. "Yea, what indignation" against him that had sinned. "Yea, what fear." For so great carefulness and very speedy reformation was the part of men who feared exceedingly. And that he might not seem to be exalting himself, see how quickly he softened it by saying, "Yea, what longing," that towards me. "Yea, what zeal," that on God's behalf. "Yea, what avenging:" for ye also avenged the laws of God that had been outraged. "In every thing ye approved yourselves to be pure in the matter." Not only by not having perpetrated, for this was evident before, but also by not consenting unto it. For since he said in the former Epistle, "and ye are puffed up;" he also says here, 'ye have cleared yourselves of this suspicion also; not only by not praising, but also by rebuking and being indignant.'

[AD 384] Ambrosiaster on 2 Corinthians 7:12
Paul is making it clear that forgiveness ought to be granted to those who did wrong not only for their sake but for the sake of the church, because when one does wrong many suffer.

[AD 407] John Chrysostom on 2 Corinthians 7:12
For that they might not say, Why then dost thou rebuke us if we were "clear in the matter?" setting himself to meet this even further above, and disposing of it beforehand, he said what he said, namely, "I do not regret, though I did regret." 'For so far,' says he, 'am I from repenting now of what I wrote then, that I repented then more than I do now when ye have approved yourselves.' Seest thou again his vehemence and earnest contention, how he has turned around what was said unto the very opposite. For what they thought would have made him recant in confusion as having rebuked them hastily, by reason of their amendment; that he uses as a proof that it was right in him to speak freely. For neither does he refuse afterwards to humor them fearlessly, when he finds he can do this. For he that said farther above such things as these, "He that is joined to an harlot is one body," and, "Deliver such an one to Satan for the destruction of the flesh," and, "Every sin that a man doeth is without the body," and such like things; how saith he here, "Not for his cause that did the wrong, nor for his cause that suffered the wrong?" Not contradicting, but being even exceedingly consistent with, himself. How consistent with himself? Because it was a very great point with him to show the affection he bore towards them. He does not therefore discard concern for him, but shows at the same time, as I said, the love he had for them, and that a greater fear agitated him, [namely] for the whole Church. For he had feared lest the evil should eat further, and advancing on its way should seize upon the whole Church. Wherefore also he said, "A little leaven leaveneth the whole lump." This however he said at the time; but now that they had well done, he no longer puts it so but differently: and implies indeed the same thing, but manages his expressions more agreeably, saying, "That our care for you might appear unto you." That is, 'that ye might know how I love you.' Now this is the same thing as the former, but being differently expressed seemed to convey another meaning.

[AD 384] Ambrosiaster on 2 Corinthians 7:13
Paul has been comforted by the fact that those whom he rebuked wished to mend their ways. But on learning from Titus that they were experiencing pain on account of their error, he was consoled even more and filled with joy, because their resolve had been confirmed by their behavior.

[AD 407] John Chrysostom on 2 Corinthians 7:13
"Therefore we have been comforted." Since we both showed our care for you and have been wholly successful. As he said also in another place, "Now we live, if ye stand fast in the Lord;" and again, "For what is our hope, or joy, or crown of rejoicing? are not even ye?" For this is life, this comfort, this consolation to a teacher possessed of understanding; the growth of his disciples. For nothing doth so declare him that beareth rule as paternal affection for the ruled. For begetting alone constitutes not a father; but after begetting, also loving. But if where nature is concerned there is so great need of love, much more where grace is concerned. In this way were all the ancients distinguished.

[AD 407] John Chrysostom on 2 Corinthians 7:13
See again how he exalts their praises, and showeth their love. For having said, 'I was pleased that my Epistle wrought so much and that ye gained so much,' for "I rejoice," he saith, "not that ye were made sorry, but that ye were made sorry unto repentance;" and having shown his own love, for he saith, "Though I wrote unto you, I wrote not for his cause that did the wrong, nor for his cause that suffered the wrong, but that our care for you might be made manifest to you:" again he mentioneth another sign of their good will, which bringeth them great praise and showeth the genuineness of their affection. For, "in your comfort," he saith, "we joyed the more exceedingly for the joy of Titus." And yet this is no sign of one that loveth them exceedingly; rejoicing rather for Titus than for them. 'Yes,' he replies, 'it is, for I joyed not so much for his cause as for yours.' Therefore also he subjoins the reason, saying, "because his bowels were refreshed by you all." He said not, 'he,' but "his bowels;" that is, 'his love for you.' And how were they refreshed? "By all." For this too is a very great praise.

[AD 407] John Chrysostom on 2 Corinthians 7:14
"For if in anything I have gloried to him on your behalf." It is high praise when the teacher boasted, for he saith, "I was not put to shame." I therefore rejoiced, because ye showed yourselves to be amended and proved my words by your deeds. So that the honor accruing to me was twofold; first, in that ye had made progress; next, in that I was not found to fall short of the truth. "But as we spake always to you in truth, so our glorying also which I made before Titus was found to be truth." Here he alludes to something further. As we spake all things among you in truth, (for it is probable that he had also spoken to them much in praise of this man,) so also, what we said of you to Titus has been proved true.

[AD 384] Ambrosiaster on 2 Corinthians 7:15
Paul is saying that Titus’s mind and affection are concerned with them, because he has seen their progress, for the mind of a saint is concerned with everything that is good. Commentary on Paul’s Epistles.
[AD 407] John Chrysostom on 2 Corinthians 7:15
"And his inward affection is more abundant toward you." What follows is in commendation of him, as exceedingly consumed with love and attached to them. And he said not 'his love.' Then that he may not appear to be flattering, he everywhere mentions the causes of his affection; in order that he may, as I said, both escape the imputation of flattery and the more encourage them by making the praise redound unto them, and by showing that it was they who had infused into him the beginning and ground of this so great love. For having said, "his inward affection is more abundant toward you;" he added, "Whilst he remembereth the obedience of you all." Now this both shows that Titus was grateful to his benefactors, seeing he had returned, having them all in his heart, and continually remembereth them, and beareth them on his lips and in his mind; and also is a greater distinction to the Corinthians, seeing that so vanquished they sent him away. Then he mentions their obedience also, magnifying their zeal: wherefore also he addeth these words, "How with fear and trembling ye received him." Not with love only, but also with excessive honor. Seest thou how he bears witness to a twofold virtue in them, both that they loved him as a father and had feared him as a ruler, neither for fear dimming love, nor for love relaxing fear. He expressed this also above, "That ye sorrow after a godly sort, what earnest care it wrought in you; yea what fear, yea what longing."

[AD 384] Ambrosiaster on 2 Corinthians 7:16
Paul is glad not only because of their good resolve but because of the good actions by which they were correcting their former sinful practices. This is why he has perfect confidence in them.

[AD 407] John Chrysostom on 2 Corinthians 7:16
"I rejoice therefore, that in every thing I am of good courage concerning you." Seest thou that he rejoiceth more on their account; 'because,' he saith, 'ye have in no particular shamed your teacher, nor show yourselves unworthy of my testimony.' So that he joyed not so much for Titus' sake, that he enjoyed so great honor; as for their own, that they had displayed so much good feeling. For that he may not be imagined to joy rather on Titus' account, observe how in this place also he states the reason. As then he said above, "If in anything I have gloried to him on your behalf I was not put to shame;" so here also, "In everything I am of good courage concerning you." 'Should need require me to rebuke, I have no apprehension of your being alienated; or again to boast, I fear not to be convicted of falsehood; or to praise you as obeying the rein, or as loving, or as full of zeal, I have confidence in you. I bade you cut off, and ye did cut off; I bade you receive, and ye did receive; I said before Titus that ye were great and admirable kind of people and knew to reverence teachers: ye proved these things true by your conduct. And he learnt these things not so much from me as from you. At any rate when he returned, he had become a passionate lover of you: your behavior having surpassed what he had been told.'
