- When Ed repents, should he repent to elders or just the congregation as a whole?
I think its viewed as a malady. The elders anoint them. Its probably public or as public as the shunning was? I assume the elders are the ones who are responsible for shunning the person from the meeting. I don't think their original sin has to be announced.
"Is anyone among you sick? Let them call the elders of the church to pray over them and anoint them with oil in the name of the Lord. And the prayer offered in faith will make the sick person well; the Lord will raise them up. If they have sinned, they will be forgiven." (Jas 5:14-15 NIV)
- Should Ed's reason's for being shunned be revealed to everyone in the local church or is it a confidential matter between him and those he confessed to or were caught by? Or does the requirements for shunning mean that the whole group knows already?
No, I don't think so. If he's excluded from the whole meeting then in the first place children should not be informed, because children don't understand. Individual men should probably not be informed, and they should be responsible to react individually. Suppose he wants to get some advice from an individual? Are you going to punish them for being merciful to him individually? That doesn't seem right. Its the same as the local shunning but in miniature. If he starts talking about how great it is to be lascivious than its up the that individual to then say "I don't want to hear it." The more times this happens the better. So if Bob doesn't know that Edgar has been shunned by the meeting and has Edgar over for dinner, that's Ok with me. Don't punish Edgar or make Edgar the enforcer for the meeting. It will work out.
Important references: I Corinthians 5, I Corinthians 6, 2 Corinthians 2. The references in I Corinthians are about expelling someone, and the one in 2 Corinthians is about forgiving and being careful not to destroy them in the process. Peace is the goal and keep the person is the goal. Don't irradiate them like a cancer. Rather, treat them like a bent reed. Put some tape on it.
Remember Peter's original name is 'Reed'. Isaiah 42:3
"A bruised reed he will not break and a smoldering wick he will not snuff out..." The person may be bent or smouldering, so straighten them out carefully or gently blow to fire them back up. Remember all the stories about reeds who have become mountains.
What about Jesus reaction to the leper? He was not concerned with contracting leprosy. He touched them. The meaning is that you shouldn't be afraid of their ideas and words. Its just the behavior mentioned in Jude that is really unacceptable. Its when they are promoting lascivious behavior and are slandering and opposing anything or anyone they don't understand. You can't keep peace under those conditions.
Jesus reached out his hand and touched the man. "I am willing," he said. "Be clean!" And immediately the leprosy left him. (Luk 5:13 NIV) Based upon this the idea of shunning shouldn't be used to exclude people that you are afraid will corrupt your pristine group with strange ideas. What is the gospel if not a strange idea coming from no authority? Who gives us permission to do what we do? Its a bit rich for us to then criticize over a difference of opinion.
- Does shunning only apply to people who advertise their sin? (Also a scripture to back up not shunning people who sin in private)
Its about keeping peace, first. That is how Satan is crushed. Hopefully the elders are clever enough to know when to act, and I mean the local elders. Anything beyond that is from church tradition not strictly extracted from the canon, and then you should also be applying other traditions if you go that route -- the route of bishops and hierarchies.
- Is there scriptural reason to support the idea that a report of Ed's deeds shouldn't be passed on to the other church?
I'm not sure if all of these are applicable, but they seem to be in the ballpark:
If you take your neighbor to court, do not betray another's confidence, (Pro 25:9 NIV)
Marriage should be honored by all, and the marriage bed kept pure, for God will judge the adulterer and all the sexually immoral. (Heb 13:4 NIV)
For I am afraid that when I come I may not find you as I want you to be, and you may not find me as you want me to be. I fear that there may be discord, jealousy, fits of rage, selfish ambition, slander, gossip, arrogance and disorder. (2Co 12:20 NIV)
On the contrary, those parts of the body that seem to be weaker are indispensable, and the parts that we think are less honorable we treat with special honor. And the parts that are unpresentable are treated with special modesty, (1Co 12:22-23 NIV)
- If someone is a danger to people, why NOT shun them?
I don't think there is specific advice for that in the canon except to use wisdom. There are a couple verses in the Torah which you could apply, but its not a direct comment. There is a law about dangerous animals. If your bull kills another bull, and you let it live and it kills again then you are responsible (have been negligent). Exodus 21:35-36. If someone is charged with murder they have to stay in a city of refuge until they are cleared, found guilty or the presiding high priest dies. Numbers 35. Its form of imprisonment, but the canon doesn't reveal the details of how harsh it is. So I guess there is some wisdom in that which can be applied by some kind of transmutation into modern times. Obviously in my opinion a dangerous person can't be allowed free reign.
