If these are tares in the Church, then they are to be cast out. If they are Christians, then they are to be reprimanded. They are not suppose to be shuffled to another job somewhere. I thought it was with some irony that Justin Martyr talked about sexual immorality with children in the letter I referenced.
I would suggest there are many biblical examples of Christians-not tares-being lax in their behavior. A case in point is the Corinthians who seemed to excuse the behavior of a man committing sexual immorality with his father's wife. (I Cor 5) Paul was pretty upset Christians were arrogant about the matter rather than mournful. We are to be the light of the world, ambassadors for Christ, holy and blameless. We are not to ignore (and excuse) bad behavior within the church. We are to act upon it.
While I'm very familiar with hierarchies having been in a number of them myself, this is one of the reasons I don't believe the early church was structure under a hierarchical system. Hierarchical systems lend themselves early to corruption. When the hierarchy votes to recognize gays to marry or women to preach, what are you going to do? Wmfights has often brought up many excellent arguments why the early churches were individually run. It's our Baptist nature.
As far as the timing of these attacks, I'd say bring them on. Our God is mighty and fully capable of anything puny man can throw at us. But if it is God's will that we perish, then so be it. We will not bow down to their satanic visions. However, just like Joshua found out at Ai, we cannot go into battle if we have sin among our mist. Keep in mind that abortion in the church mirrors secular society. We need to repent and cleanse ourselves.
This is an excellent scripture, but you do recall that Paul was willing to make an attempt to redeem the individual in question. If I recall 2 Corinthians correctly, Paul's gambit paid off. The man repented.
Now, I think that the statistical data is irrefutable that there is so little success (none) in rehabbing certain varieties of sex offenders that it MUST become policy that they be totally removed from any position of authority or ministry within the church. There must be no return ever to such a position. If ordained, they must be stripped of their orders. Forever. They must have their bodies "turned over to Satan for the destruction of their flesh that their spirits may be saved in the Day of the Lord." And if some of them truly repent, then so much the better. But they must never, ever be restored to authority/ministry. Ever.
My denomination also has a very involved system with the "rights of defendants" identical to those in our US justice system. In short, it's virtually impossible to convict anyone of anything short of a video showing them in the act. This does carry protection of the individual in church matters a bit too far. We must not entertain accusations against elders on the testimony of one witness, but we also must allow reasonable accusations to see the light of day and receive a fair hearing.
It is just as important to protect the sheepfold as it is to protect members from false accusation.
