Romans 16:17
I urge you, brothers and sisters, to watch out for those who cause divisions and put obstacles in your way that are contrary to the teaching you have learned. Keep away from them.
2 Thessalonians 3:6
In the name of the Lord Jesus Christ, we command you, brothers and sisters, to keep away from every believer who is idle and ...[text shortened]... ivisive person once, and then warn them a second time. After that, have nothing to do with them.
I think one of the questions is, what constitutes a division deserving of disfellowship? The Wikipedia article on excommunication addresses this, although it is not to be taken as having the JW imprimatur:
"Jehovah's Witnesses practice something similar to excommunication, using the term "disfellowshipping", in cases where, it is believed, a member has unrepentantly committed one or more of several documented "serious sins".[22]
The verses of Scripture that Witnesses appeal to for expelling unrepentant believers is 1 Corinthians 5:11-13 and 2 John 10, where it says "quit mixing in company with anyone called a brother that is a fornicator or greedy person or an idolater or a reviler or a drunkard or an extortioner, not even eating with such a man....remove the wicked man from your midst" and "never receive him in your home or say a greeting to him." They interpret this to mean that any baptized believer who engages in "gross sins", mentioned in the Bible is, to be expelled from the congregation and shunned."
Another concern I have is that disfellowship can have serious psychological and social effects on a person. Perhaps moreso in a small homogeneous community where a person can in effect be banished from the community while not physically ejected. Finding work, purchasing food, etc. could become impossible. In our modern generally secular world, this is not so much a problem, and disfellowed JWs, excommunicated Catholics, etc. can get along OK in life. Keeping it that way is important.
