Sufficient to such a man is this punishment, which was inflicted of many.
Sufficient - Greek х hikanon (G2425)], 'a sufficiency' (since he is repenting, 2 Corinthians 2:2; 2 Corinthians 2:7) - without continuing it, so as to drive him to despair (2 Corinthians 2:7); whereas the object of the punishment was, 'that (his) spirit might be saved.'
To such a man - implying past estrangement from such a one who had caused such grief to the church and scandal to religion (Acts 22:22; 1 Corinthians 5:5).
This punishment - his being 'delivered to Satan for the destruction of the flesh:' not only excommunication, but bodily disease (notes, 1 Corinthians 5:4-5).
Inflicted of many - Greek, 'by the majority' of you. Not by an individual priest, as in Rome, nor by the bishops and clergy alone, but by the whole body of the church.
