For this it was enough to show by deed that they protect themselves and try to extract their own gain from everything, while wearing the mask of ministers of Christ. But suffering for Christ, which is essentially necessary for true ministers of Christ, they never suffered, and they do not know how to set foot on this path.” “In labors, in prisons, in deaths often.” The labors and sufferings of Paul’s apostleship are beyond description. According to Clement, bishop of Rome, he was imprisoned seven times. He was exposed to mortal danger many times. Five times he was beaten with thirty-nine blows, so that no extra blow should be given beyond what the law allowed (Deut 25:3). Of the three beatings with rods, only one is mentioned in Acts. That case, it seems, was a special one (Acts 16:22). He was stoned almost to death in Lystra (Acts 14:19). The Apostle often traveled by sea. During one of three shipwrecks, he was carried by the waves in the deep for a night and a day, probably after grasping some fragment of the ship. The false teachers did not wish to suffer for Christ. Therefore they boasted of certain external distinctions, knowing how to present them as exalted before the inexperienced Corinthians. For example, they said they were the seed of Abraham, heirs of the great promises given to Abraham. But the Apostle had already said that this boasting was fleshly (verse 18). Now he shows that he too possesses all these supposed fleshly advantages. “Having shown his equality with them in this, he shows his superiority in voluntary achievements” (Theodoret).
