Disfellowshipping is a procedure which is laid down in the Bible . . . A young woman who was disfellowshipped and later reinstated said: "I am happy that Jehovah loves his people enough to see that his organization is kept clean. What may seem harsh to outsiders is both necessary and really a loving thing to do. I am grateful that our heavenly Father is a loving and forgiving God."
Robert Pevy, Jehovah's Witnesses Writing Staff;
TRT: 2:20

Do you shun former members?
Those who become inactive in the congregation, perhaps even drifting away from association with fellow believers, are not shunned. In fact, special effort is made to reach out to them and rekindle their spiritual interest. If, however, someone unrepentantly practices serious sins, such as drunkenness, stealing or adultery, he will be disfellowshipped and such an individual is avoided by former fellow-worshipers. Every effort is made to help wrongdoers. But if they are unrepentant, the congregation needs to be protected from their influence. The Bible clearly states: 'Remove the wicked man from among yourselves.' (1 Corinthians 5:13) Those who formally say they do not want to be part of the organization any more are also avoided. What of a man who is disfellowshipped but whose wife and children are still Jehovah's Witnesses? The spiritual ties he had with his family change, but blood ties remain. The marriage relationship and normal family affections and dealings can continue. As for disfellowshipped relatives not living in the same household, Jehovah's Witnesses apply the Bible's counsel: "Quit mixing with them." (1 Corinthians 5:11) Disfellowshipped individuals may continue to attend religious services and, if they wish, they may receive spiritual counsel from the elders with a view to their being restored. They are always welcome to return to the faith if they reject the improper course of conduct for which they were disfellowshipped.
(what they don't say is that if you return you are shunned until such time they decide you have 'repented' so although you are 'welcome' back at the meetings you generally sit at the back of the hall in designated seats for however many months or years it takes, and are not spoken to by the members of the congregation until your 'reinstatement')
