2 Corinthians 2:3

I wrote this same unto you,— That I wrote relates to the first epistle to the Corinthians is evident, because it is so used in the next and the ninth verse; and what he wrote in that epistle, which he calls αυτο τουτο, this very thing, was, most probably, concerning the punishment of the fornicator; as appears by what follows to 2 Corinthians 2:11 especially if it be compared with 1 Corinthians 4 and 1 Corinthians 5:8. For there he writes to them to punish that person; and if St. Paul had come himself before it was done, he must have come with a rod, as he calls it, and have himself chastised them: but now, knowing that the Corinthians had punished him, in compliance with his letter, and having had this trial of their obedience, and the offender being become a genuine penitent, he is so far from continuing the severity, that he writes to them to forgive him, and to take him again into their affection.
