CLAIM: Paul writes about a believer that was kicked out of the church in Corinth. Who is he referring to?
RESPONSE: Depending on your view of a lost letter in between 1 and 2 Corinthians (see comments on 2 Corinthians 2:4), you will have different views on this question. It is the view of this author that the man mentioned here is the same man who was removed from fellowship in 1 Corinthians 5. The Corinthian church was formerly licentious, permitting this man to sleep with his stepmother. However, after Paul’s rebuke in 1 Corinthians, they must have swung to the opposite side of the spectrum, taking an unforgiving stance in church discipline (c.f. 1 Cor. 5:1-13; 3 Jn. 10).
