(I just finished re-reading this before posting, and I guess it is more of an anti-shunning reflection, rather than an argument against disfellowshipping, but I'll leave it here anyways. Sorry if it seems off-topic)
I was just reading the 1 Cor example (for the zillionth time) last night, ignoring the during the drudge of the book study, and as I was reading, it struck me (in a way it hadnt before) that Paul said to put the man out so that SATAN could have his way with him, not so that the rest of the congregation could punish him by shunning him.
5 I have decided to deliver such a one to Satan for the destruction of his flesh, so that his spirit may be saved in the day of the Lord Jesus. (1Cor5:5 NASB)
It wasnt for the congregation to 'actively' punish him anymore than to remove him from the church (clean out the old leaven). Yet, how is a 'brother who doesnt listen" supposed to be treated"
17 ......if he refuses to listen even to the church, let him be to you as a Gentile and a tax collector. (Matt18:17 NASB)
Once he was 'put out' for Satan, he obviously became 'part of the world', no longer a brother, no longer a member of the church, but just part of the world. Paul's instructions to the church re: those "of the world' was not to "judge them" :
9 I wrote you in my letter not to associate with immoral people;10 I did not at all mean with the immoral people of this world, or with the covetous and swindlers, or with idolaters, for then you would have to go out of the world.
11 But actually, I wrote to you not to associate with any so-called brother if he is an immoral person, or covetous, or an idolater, or a reviler, or a drunkard, or a swindler--not even to eat with such a one.
12 For what have I to do with judging outsiders? Do you not judge those who are within the church?
13 But those who are outside, God judges.
(1Cor5:9-13)
By putting such a one out of the church, the congregation is openly stating that such a one is no longer a brother (or sister), so Paul's admonition not to associate DOES NOT apply to those who are outside, who are "of the world", those who are not brothers, including the one who is removed from the church. Morover one's outside the church are EXACTLY the ones that members of the church are supposed to go to! For didnt Jesus goto and eat and drink with the sinners?
9 As Jesus went on from there, He saw a man called Matthew, sitting in the tax collector's booth; and He said to him, "Follow Me!" And he got up and followed Him.
10 Then it happened that as Jesus was reclining at the table in the house, behold, many tax collectors and sinners came and were dining with Jesus and His disciples.
11 When the Pharisees saw this, they said to His disciples, "Why is your Teacher eating with the tax collectors and sinners?"
12 But when Jesus heard this, He said, "It is not those who are healthy who need a physician, but those who are sick.
13 "But go and learn what this means: 'I DESIRE COMPASSION, AND NOT SACRIFICE,' for I did not come to call the righteous, but sinners." (Matt9:9-13 NASB)
Further more, once one is outside, do you suppose it is proper to leave such a sheep alone, to totally forsake such a one to Satan's ways? Hasn't the one who has been put of the church been put out precisely becuase he has 'strayed' from the truth? Yet what is supposed to happen in such a case:
12 "What do you think? If any man has a hundred sheep, and one of them has gone astray, does he not leave the ninety-nine on the mountains and go and search for the one that is straying? (Mat.18:12 NASB)
So basically I used the sickenly dull book study to truly reflect upon this whole disfellowshipping/shunning thing (again) and concluded (again) that while it may be that there do arise occassions where church members are to "not associate with a so-called brother" who continuously practices sin unrepentently and should stop calling a 'brother or sister' (i.e put out of the church) one who continuously practices sin unrepentently, it is completely unscriptual to judge or act towards such a person in the manner as taught by JWs. As a matter of fact, JWs go far beyond the admonition of scripture and do exactly the opposite of what they are supposed to do with regards to sinners and people 'of the world'.
