Hi Johnamos
Nicely cherrypicked scriptures. There is a danger in applying 1 scripture literally without a proper context.
Remember Pauls letters are written to the congregations - not elders only. He was warning people to watch out who they associate with - no shunning is defined here in the deformed way it is practised in the JW faith.
Mat 18 - there is no Judicial committee here formed by a body of elders. Congregations were small and thus handled in a very different way. How does this relate in any way to the way a Judicial committee is run. Where here does it say you can disfellowship a person because they were repentant in a "wordly way" but not a "godly way". Were does it say here that you ask a person how many times they had sex with another person to identify if they are really repentant. If you look at verse 22, do we apply the 77 times literally also?
1 Cor 5 - in the very next book Paul says to welcome him back in. Again in no way supports how we handle cases like these and how we treat "sinners".
2 John - is talking about the anti-christ not other sins. Of course we would not want to associate with them, but we can still treat another human with dignity. Again no judicial process is here mentioned.
2 Thess 3 - yes it is obvious that if a friend gets drunk and starts smashing your house you would remove him right? Same applies here - but notice vs 15 - And yet do not consider him an enemy, but continue admonishing him as a brother - hmmm - can't see shunning here either?
Rom 16 - yes if you had a group of any sort meet at your house and you had a person causing troubles and divisions you would avoid them also. But avoiding is not shunning. No elders are involved, no committees, etc.
So far I cannot see proper scriptural support for the way JW's handle committee cases.
I understand the need to watch out for people who could influence you but that applies to our general daily lives. You could apply that to a circle of friends.
