13. How would parents deal with a disfellowshiped child in the home?
13 If a minor child is disfellowshiped, the parents will still care for his physical needs and provide moral training and discipline. They would not conduct a Bible study directly with the child, with him participating. Yet this does not mean that he would not be required to sit in on the family study. And they might direct attention to parts of the Bible or Christian publications that contain counsel he needs. (Prov. 1:8-19; 6:20-22; 29:17; Eph. 6:4) They can have him accompany them to and sit with them at Christian meetings, hoping that he will take to heart Biblical counsel.

If the child is a minor and is living at home, you will naturally continue to take care of his physical needs. He also requires moral training and discipline, and you have the responsibility to provide these. (Proverbs 1:8-18; 6:20-22; 29:17) You may want to conduct a Bible study with him, involving his direct participation. You can draw his attention to various scriptures and to the publications provided by “the faithful and discreet slave.” (Matthew 24:45) You can also take the child with you to Christian meetings and have him sit with you. All of this can be done in hopes that he will take Scriptural counsel to heart.

8. What responsibility do Christian parents have toward a minor disfellowshipped child living in the home?
8 If a minor child living in the home is disfellowshipped, Christian parents are still responsible for his upbringing. The Watchtower of November 15, 1988, page 20, states: “Just as they will continue to provide him with food, clothing, and shelter, they need to instruct and discipline him in line with God’s Word. (Proverbs 6:20-22; 29:17) Loving parents may thus arrange to have a home Bible study with him, even if he is disfellowshipped. Maybe he will derive the most corrective benefit from their studying with him alone. Or they may decide that he can continue to share in the family study arrangement.”—See also The Watchtower of October 1, 2001, pages 16-17.
