2 Corinthians 12:7

"And that I should not be exalted overmuch, through the exceeding greatness of the revelations, there was given to me a thorn in the flesh, a messenger of Satan, to buffet me." What sayest thou? He that counted not the kingdom to be any thing; no, nor yet hell in respect of his longing after Christ; did he deem honor from the many to be any thing, so as both to be lifted up and to need that curb continually? for he did not say, 'that he "might" buffet me,' but "that he" may "buffet me." Yet who is there would say this? What then is the meaning of what is said? When we have explained what is meant at all by the "thorn," and who is this "messenger of Satan," then will we declare this also. There are some then who have said that he means a kind of pain in the head which was inflicted of the devil; but God forbid! For the body of Paul never could have been given over to the hands of the devil, seeing that the devil himself submitted to the same Paul at his mere bidding; and he set him laws and bounds, when he delivered over the fornicator for the destruction of the flesh, and he dared not to transgress them. What then is the meaning of what is said? An adversary is called, in the Hebrew, Satan; and in the third Book of Kings the Scripture has so termed such as were adversaries; and speaking of Solomon, says, 'In his days there was no Satan,' that is, no adversary, enemy, or opponent. What he says then is this: God would not permit the Preaching to progress, in order to check our high thoughts; but permitted the adversaries to set upon us. For this indeed was enough to pluck down his high thoughts; not so that, pains in the head. And so by the "messenger of Satan," he means Alexander the coppersmith, the party of Hymenaeus and Philetus, all the adversaries of the word; those who contended with and fought against him, those that cast him into a prison, those that beat him, that led him away to death; for they did Satan's business. As then he calls those Jews children of the devil, who were imitating his deeds, so also he calls a "messenger of Satan" every one that opposeth. He says therefore, "There was given to me a thorn to buffet me;" not as if God putteth arms into such men's hands, God forbid! not that He doth chastise or punish, but for the time alloweth and permitteth them.
