I do not believe in the bible but I will use the reasoning from the New Testament to argue against Watchtower. The reason I will only use the New Testament is that Jesus replaced the Mosaic Law with himself. Even Watchtower agree with this principle.
Why do Watchtower use judicial committees to judge. There were no judicial committees in the first century. The only arrangement for the elders was to help spiritually sick to have a clean conscience. James 5:13-15. The only law Jesus gave was to love one another. Freeing the jews from the law of the Pharisees who put to many burdens on the Jews. Jesus also gave a commandment Not to judge as you will be judged by god.
The Watchtower pick and choose what they want from the old testament. For example, no tattoos, no dressing up in clothing that resembles that of the opposite sex. There is more of these but I will not add further examples. An exception to this is beards. It was a reqirement for Jews to have beards from the mosaic law. But this is a no no according to the Watchtower who seem to be inconsistent without justification.
For any of you JW lurkers reading this, take note. You are being deceived.
To sum up. Judicial Committees make a judgement that causes all sorts of grief. JESUS gave us a commandment not to judge. Further to this he said to treat everyone as brothers and sisters. No governing body was set up in the first century.
