Separation in The Church - Forgiveness

(2 Corinthians 2:3-9 NKJV)

3 And I wrote this very thing to you, lest, when I came, I should have sorrow over those from whom I ought to have joy, having confidence in you all that my joy is the joy of you all. 4 For out of much affliction and anguish of heart I wrote to you, with many tears, not that you should be grieved, but that you might know the love which I have so abundantly for you. 5 But if anyone has caused grief, he has not grieved me, but all of you to some extent—not to be too severe. 6 This punishment which was inflicted by the majority is sufficient for such a man, 7 so that, on the contrary, you ought rather to forgive and comfort him, lest perhaps such a one be swallowed up with too much sorrow. 8 Therefore I urge you to reaffirm your love to him. 9 For to this end I also wrote, that I might put you to the test, whether you are obedient in all things.
