Paul's Authority (2)
Paul changes topics here to address his opponents in Corinth (chs. 10–13), offering an impassioned defense of his apostleship. He begins by stating that God gave him his authority (v. 8). He encourages the Corinthians not to consider appearances (v. 7) and points out that he does not compare himself with others (v. 12). Paul then contrasts himself with those who commend themselves, pointing out that he only boasts in the Lord (vv. 12–18).
b. Paul responds to criticisms (10:7–11)
In this passage Paul responds to two criticisms levelled against him by his opponents: first, that he was no true servant of Christ while they themselves were (vv. 7–8), and second, that while his letters were ‘weighty and strong’, his ‘bodily presence [was] weak, and his speech of no account’ (vv. 9–11).
It is important to recognize that apostolic authority was of the greatest significance for Paul. He was an ambassador for Christ (5:20), and as such spoke the message entrusted to him with the full authority of his Lord. Because of this Paul expected to be obeyed; anyone who rejected his instructions rejected the word of the Lord (1 Cor. 14:37–38). And because he was entrusted with such authority Paul was careful to distinguish the word of the Lord from his own good advice and from other statements he sometimes felt forced to make (1 Cor. 7:10, 25; 2 Cor. 11:17).
building you up Some Corinthians may have perceived that Paul used his authority to oppress or take advantage of them (12:17). Paul identifies the true purpose of his authority: to strengthen the faith of believers so they grow in maturity.
In this verse Paul’s eyes are upon the ultimate evaluation of a person’s ministry. It matters little what the individual says by way of self-recommendation or what judgments others make. All that matters is the commendation which the Lord himself gives (cf. 1 Cor. 4:1–5).
