1 Corinthians 5:5 - Wesley's Explanatory Notes

To deliver such an one — This was the highest degree of punishment in the Christian church; and we may observe, the passing this sentence was the act of the apostle, not of the Corinthians. To Satan — Who was usually permitted, in such cases, to inflict pain or sickness on the offender. For the destruction — Though slowly and gradually. Of the flesh — Unless prevented by speedy repentance.
