2:5-11 The apostle desires them to receive the person who had done wrong, again into their communion; for he was aware of his fault, and much afflicted under his punishment. Even sorrow for sin should not unfit for other duties, and drive to despair. Not only was there danger last Satan should get advantage, by tempting the penitent to hard thoughts of God and religion, and so drive him to despair; but against the churches and the ministers of Christ, by bringing an evil report upon Christians as unforgiving; thus making divisions, and hindering the success of the ministry. In this, as in other things, wisdom is to be used, that the ministry may not be blamed for indulging sin on the one hand, or for too great severity towards sinners on the other hand. Satan has many plans to deceive, and knows how to make a bad use of our mistakes.
5. grief … grieved—Translate as before, "sorrow … made sorry." The "any" is a delicate way of referring to the incestuous person.
not … me, but in part—He has grieved me only in part (compare 2Co 1:14; Ro 11:25), that is, I am not the sole party aggrieved; most of you, also, were aggrieved.
that I may not overcharge—that I may not unduly lay the weight of the charge on you all, which I should do, if I made myself to be the sole party aggrieved. Alford punctuates, "He hath not made sorry me, but in part (that I press not too heavily; namely, on him) you all." Thus "you all" is in contrast to "me"; and "in part" is explained in the parenthetical clause.
