The September 15, 1981 Watchtower made it clear that shunning was back in full force:
11 The expelled person is not a mere man of the world who has not known God nor pursued a godly way of life. Rather, he has known the way of truth and righteousness, but he has left that way and unrepentantly pursued sin to the point of having to be expelled. So he is to be treated differently. Peter commented on how such former Christians differ from an average "man on the street." The apostle said: "If, after having escaped from the defilements of the world by an accurate knowledge of the Lord and Savior Jesus Christ, they get involved again with these very things and are overcome, the final conditions have become worse for them than the first. . . . The saying of the true proverb has happened to them: 'The dog has returned to his vomit, and the sow that was bathed to rolling in the mire.'"—2 Pet. 2:20-22; 1 Cor. 6:11.
12 Yes, the Bible commands Christians not to keep company or fellowship with a person who has been expelled from the congregation. Thus "disfellowshiping" is what Jehovah's Witnesses appropriately call the expelling and subsequent shunning of such an unrepentant wrongdoer. Their refusal to fellowship with an expelled person on any spiritual or social level reflects loyalty to God's standards and obedience to his command at 1 Corinthians 5:11, 13. This is consistent with Jesus' advice that such a person be considered in the same way as "a man of the nations" was viewed by the Jews of that time. For some time after the apostles died, those professing Christianity evidently followed the Biblical procedure. But how many churches today comply with God's clear directions in this regard?
