<p>10:17 <i>But he that boasts, let him boast in the Lord- </i>This is the quotation from Jer. 9:24 with which Paul began his recorded letters to the Corinthians (1 Cor. 1:31). But I have shown in earlier commentary on this chapter that Paul's attitude is at variance with the non-partisan spirit which he had shown there. Despite knowing this principle, Paul is now as it were carried away to boast in the flesh. Again he states a principle and then appears to break it, as witnessed in his promise to entreat them by the gentleness of Christ (10:1) and going on to use bitter sarcasm and angry manipulation against them. This confirms my conclusion that this letter is an inspired 'flow of consciousness' recording of Paul's feelings. The context of Jer. 9:24 urges glorying in the Lord because judgment is coming- and that rather fits what Paul is going on to threaten.</p>
