We are fools for Christ's sake, but ye are wise in Christ; we are weak, but ye are strong; ye are honourable, but we are despised. We are fools for Christ's sake - Here he still carries on the allusion to the public spectacles among the Romans, where they were accustomed to hiss, hoot, mock, and variously insult the poor victims. To this Philo alludes, in his embassy to Caius, speaking of the treatment which the Jews received at Rome: ὡσπερ γαρ εν θεατρῳ κλωσμοσυριττοντων, καταμωκωμενων, αμετραχλευαζοντων· "For, as if exhibited upon a theater, we are hissed, most outrageously hooted, and insulted beyond all bounds." Thus, says the apostle, we are fools on Christ's account; we walk in a conformity to his will, and we bear his cross: and did we walk according to the course of this world, or according to the man-pleasing conduct of some among you, we should have no such cross to bear.
Ye are wise in Christ - Surely all these expressions are meant ironically; the apostles were neither fools, nor weak, nor contemptible; nor were the Corinthians, morally speaking, wise, and strong, and honorable. Change the persons, and then the epithets will perfectly apply.
