So the JW are great with quoting 1 Corthians 5:12 put the wicked man out! or away!
2Corthians 2 - Pauls Teary Letter:
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. 10 Now whom you forgive anything, I also forgive. For if indeed I have forgiven anything, I have forgiven that one[a] for your sakes in the presence of Christ, 11 lest Satan should take advantage of us; for we are not ignorant of his devices
As far as I am concerned, Paul had a change of heart after he set matters straight about the law of love. He did not mean to throw everthing away! For example, sex with ones Father's wife and taking her for his own! Most of what is mentioned in 1 Corthians 5 are written in the ten commandments.
So I imagine during Paul's time they were throwing the ten commandments away and praticing a new movement with different laws, "Law of love!"
The point is the JWs do not apply 1 Corthians 5 to 2 Corthians 2. Only until they want to reinstate someone. It misapplied!
Considering one does not throw the wicked person out to mean let them sit in the back row!
Many commentaries call 2 Corthians 2 Paul's "Teary Letter"
