For I made up my mind not to make another painful visit to you. For if I cause you pain, who is there to make me glad but the one whom I have pained? And I wrote as I did, so that when I came I might not suffer pain from those who should have made me rejoice, for I felt sure of all of you, that my joy would be the joy of you all. For I wrote to you out of much affliction and anguish of heart and with many tears, not to cause you pain but to let you know the abundant love that I have for you.
Now if anyone has caused pain, he has caused it not to me, but in some measure—not to put it too severely—to all of you. For such a one, this punishment by the majority is enough, so you should rather turn to forgive and comfort him, or he may be overwhelmed by excessive sorrow. So I beg you to reaffirm your love for him. For this is why I wrote, that I might test you and know whether you are obedient in everything. Anyone whom you forgive, I also forgive. Indeed, what I have forgiven, if I have forgiven anything, has been for your sake in the presence of Christ, so that we would not be outwitted by Satan; for we are not ignorant of his designs.
