What Paul expresses in this passage might seem like the foolishness of a fool. However, by accepting it and calling it foolishness, he exorcises, purifies, and turns it into a weapon in his argument against his opponents. It is no coincidence that this part of the letter is called ‘the discourse of folly.’ The Apostle is willing to do anything in defense of the Gospel he preaches, even to present himself as a ‘fool’ boasting about himself.
