cross of Christ should be made of none effect.
(19) The taking away of an objection: that he gave not himself to baptize many amongst them: not for the contempt of baptism, but because he was mainly occupied in delivering the doctrine, and committed those that received his doctrine to others to be baptized. And so he declared sufficiently how far he was from all ambition: whereas on the other hand they, whom he reprehends, as though they gathered disciples to themselves and not to Christ, bragged most ambitiously of numbers, which they had baptized.
(20) Now he turns himself to the teachers themselves, who pleased themselves in brave and glory-seeking eloquence, to the end that they might draw more disciples after them. He openly confesses that he was not similar to them, opposing gravely, as it became an apostle, his example against their perverse judgments: so that this is another place in this epistle with regard to the observing of a godly simplicity both in words and sentences in teaching the Gospel.
(l) With eloquence: which Paul casts off from himself not only as unnecessary, but also as completely contrary to the office of his apostleship: and yet Paul had this kind of eloquence, but it was heavenly, not of man, and void of fancy words.
(21) The reason why he did not use the pomp of words and fancy speech: because it was God's will to bring the world to his obedience by that way, by which the most foolish among men might understand that this work was done by God himself, without the skill of man. Therefore as salvation is set forth to us in the Gospel by the cross of Christ, which nothing is more contemptible than, and more far from life, so God would have the manner of the preaching of the cross, most different from those means with which men do use to draw and entice others, either to hear or believe: therefore it pleased him by a certain kind of most wise folly, to triumph over the most foolish wisdom of the world, as he had said before by Isaiah that he would. And by this we may gather that both these teachers who were puffed up with ambitious eloquence, and also their hearers, strayed far away from the goal and mark of their calling.
