2 Corinthians 12:7

And lest I should be exalted - There were three evils to be guarded against:

1. The contempt of his gifts and call by his enemies.

The overweening fondness of his friends. And, Self-exultation.

A thorn in the flesh - The word σκολοψ signifies a stake, and ανασκολοπιζεσθαι , to be tied to a stake by way of punishment; and it is used, says Schoettgen, to signify the most oppressive afflictions. Whatever it was, it was τῃ σαρκι , in the flesh, i.e. of an outward kind. It was neither sin nor sinfulness, for this could not be given him to prevent his being exalted above measure; for sin never had and never can have this tendency. What this thorn in the flesh might be has given birth to a multitude of conjectures: Tertullian thought it dolor auriculae , the ear ache; Chrysostom, κεφαλαλγια , the head ache; Cyprian, carnis et corporis multa ac gravia tormenta , many and grievous bodily torments. I believe the apostle to refer simply to the distresses he had endured through the opposition he met with at Corinth; which were as painful and grievous to him as a thorn in his flesh, or his being bound to a stake; for, if he could have devoted himself to destruction, Romans 9:3 , for his rebellious and unbelieving countrymen, what must he have suffered on account of an eminent Church being perverted and torn to pieces by a false teacher! God permitted this to keep the apostle humble, and at last completely delivered the Church out of the hands and influence of this deceiver; none, not even the incestuous person, having been turned finally out of the way by the false doctrines there preached.

The messenger of Satan - Another mode of expressing what he calls the thorn in the flesh; and he seems most plainly to refer to the false apostle at Corinth. The apostle himself was, as he styles himself to this Church, αποστολος Ιησου Χριστου , 2 Corinthians 1:1 , the apostle of Jesus Christ. The person in question is styled here αγγελος Σαταν , the apostle or angel of Satan. It is almost impossible to mistake the apostle's meaning and reference. Jesus Christ sent Paul to proclaim his truth, and found a Church at Corinth. Satan, the adversary of God's truth, sent a man to preach lies at the same place, and turn the Church of God into his own synagogue; and by his teaching lies and calumnies the apostle was severely buffeted. We need seek no other sense for these expressions. Many, however, think that the apostle had really some bodily infirmity that rendered him contemptible, and was the means of obstructing the success of his ministry; and that the false apostle availed himself of this to set St. Paul at nought, and to hold him out to ridicule. I have shown this, elsewhere, to be very unlikely.

The best arguments in favor of this opinion may be found in Whitby; but I forbear to transcribe them because I think the meaning given above is more correct. No infirmity of body nor corporeal sufferings can affect and distress a minister of the Gospel, equally to the perversion or scattering of a flock, which were the fruit of innumerable labors, watchings, fastings, prayers, and tears.
