For to this end also did I write - The apostle did not say that this was the only purpose of his writing, to induce them to excommunicate the offender. He does not say that he wished in an arbitrary manner to test their willingness to obey him, or to induce them to do a thing in itself wrong, in order to try their obedience. But the meaning is this: This was the main reason why he wrote to them, rather than to come personally among them. The thing ought to have been done; the offender ought to be punished; and Paul says that he adopted the method of writing to them rather than of coming among them in person, in order to give them an opportunity to show whether they were disposed to be obedient. And the sense is, "You may now forgive him. He has not only been sufficiently punished, and he has not only evinced suitable penitence, but also another object which I had in view has been accomplished. I desired to see whether you were, as a church, disposed to be obedient. That object, also, has been accomplished. And now, since everything aimed at in the case of discipline has been secured, you may forgive him, and should, without hesitation, again receive him to the bosom of the church."

For to this end also did I write - Εγραψα, I have written this also, the advices and commands which I now give you, that I might know whether ye be obedient in all things.

For to this end also did I write,.... Or "I have written", both in this and in his former epistle to them, and in both with this view,

that I might know the proof of you; that he might try, prove, and know them:

whether ye be obedient in all things; he wrote unto them in his former epistle, to put away that wicked man from them; which he did not do, merely to reproach the man, and fix a brand of infamy on him; nor merely to grieve and afflict their minds; nor only to show his own power and authority, which he as an apostle had received from Christ, but to make trial of their obedience; and he had had a proof of it in their rejection of him; and now he writes unto them, that since this man was truly humbled for his sin, and had repentance unto life not to be repented of, that they would as cheerfully receive him, and restore him to his place; that as the apostle had a proof of their obedience in the one, he might also have in the other, and so in all things: hence it appears, that though it belongs to the whole church, and that only, to reject or receive members, yet as ministers of the Gospel are set over the churches, to govern, guide, direct, and go before in matters of discipline; so whatever they propose, according to the rule of God's word, ought to be carefully attended to and obeyed.

The proof of you (τὴν δοκιμὴν ὑμῶν)

See on Romans 5:4. Your tried quality. See on 1 Peter 1:7. Compare Philippians 2:22.

For to this end also did I write, that I might know the proof of you, whether ye be obedient in all things.

2:9 For to this end also did I write. One object of his writing was to test their obedience.

Whether ye be obedient in all things. He commanded positively in 1Co 5:11,13.

9. For-Additional reason why they should restore the offender, namely, as a "proof" of their obedience "in all things"; now in love, as previously in punishing (2Co 2:6), at the apostle's desire. Besides his other reasons for deferring his visit, he had the further view, though, perhaps, unperceived by them, of making an experiment of their fidelity. This accounts for his deferring to give, in his Epistle, the reason for his change of plan (resolved on before writing it). This full discovery of his motive comes naturally from him now, in the second Epistle, after he had seen the success of his measures, but would not have been a seasonable communication before. All this accords with reality, and is as remote as possible from imposture [Paley, Horæ Paulinæ]. The interchange of feeling is marked (2Co 2:4), "I wrote . that ye might know the love," &c.: here, "I did write, that I might know the proof of you."

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.
