John Chrysostom
After showing this equality, he also sets forth his superiority, saying: "For even if I should boast somewhat more of our authority, which the Lord gave me for your edification and not for your destruction, I shall not be put to shame" (v. 8).
See how he softens his speech when he is about to say something great about himself. Indeed, nothing is so unpleasant to many hearers as self-praise.
Therefore, removing the unpleasantness, the apostle says: "even if I should boast somewhat more." He did not say: if anyone is confident in himself that he is Christ's, let him consider that he is still far below us.
Nor did he say: I received from the Lord such great authority that I can punish and hand over to death whomever I wish.

What then did he say? "Even if I should somewhat more." Although one cannot express how great an authority he had, in his words he diminishes it.
Nor did he say, "I boast," but, "if I should boast," meaning, "if I wish to boast." In this way he both preserves modesty and shows his superiority.
"For even if I should," he says, "boast of the authority which the Lord gave" me. Again he attributes everything to God and makes the gift common, saying, "for edification and not for destruction."
Do you see how he again calms the envy that his self-praise might have stirred up? He draws the hearer to himself by pointing to the benefit for which he received authority.
How then does he say, "we overthrow reasonings"? This is especially a form of edification: to remove obstacles, expose what is rotten, and establish only what is true.
"For edification." "Therefore, we received authority in order to build. Yet if someone persists, resists, and gives no hope of correction, we shall use another power: we shall cast him down and overthrow him."
Therefore he adds, "I shall not be put to shame," that is, "I shall prove neither a liar nor vainglorious."
