That's not the point IMO. Those who are shunned should be those who KNOW their actions are wrong and think it is our business to stay out of theirs. That's not how a healthy body works IMO. I do think their 'attitude' is more important than their 'sin'.
Well, yeah, I think I can agree with that. A dirty cop, a pastor caught in bed with someone else's wife, a church "protesting" funerals or obveresly, actually supporting violence.....there are definite examples of people that need to be shunned or shocked back to reality.
It's all a matter of degree. I think "shunning" someone who does or does not believe in the "trinity" or has a more or lesser docetic view of Christ, or one who won't even drink coffee or another that has a nightcap before bed is just plain silliness though. It happens, because of one of the basic tenets of humanity---"You can't fix stupid". Some people who claim that they "put on the mind of Christ" must be trying to convince the world that Christ was dumber than Bubba at the local Snack and Go.
It's always a matter of degree, and hopefully we learn from our own lives. My father taught me to lie---by physically punishing every wrong, so I would just lie and say "wasn't me". I learned. My kids were seldom punished for a wrong, just for lying about it. "please don't do that again, and this is why" went a long way to producing children that grew into responsible adults.
It's the ones that lie or rationalize away what they wouldn't reveal in the light of day, or are just plain habitually obnoxious, that need the wake up call. "Obnoxious you say?" Yeah, and that is a biggie. Who wants to spend eternity with an obnoxious neighbor? That would be more like hell than like heaven. I don't think God lets them in.
When people join our church, we tell them "this is what we believe and practice. We don't ask that everyone stay in lockstep, but we aren't interested in hearing, in church anyway, teachings about lizardmen from Mars. What you do in your personal life is your own buisiness, between you and God, but what we discuss here may affect you and what you do at home, we hope, in a positive manner. "
It's the people who refuse to be affected in a positive manner that we suggest to that they might be happier somewhere else.
