Sagacius, he left, but he didn't get kicked out. Not only that, but he came back and dealt some serious ass-whooping regarding things he didn't like during a recent visit. It also seems that he has authority at the time of the letter writing, but that his authority is being questioned. You can note this, because he tells them that while he is glad they did what he told them about the "sinner" they were a bit too harsh and need to be nice to the guy now. There are cues to let you know he is in charge, but his authority is under fire. It seems now that there is a group of individuals who oppose Paul, and are making some accusations that Paul is addressing.
Thanks for clearing that up. All I could tell from reading it is that there was some politicking going on behind the curtains and he was getting pretty sore over it.
You simply have to inform the Christian that everything should be questioned. He should be asking himself "Did this really happen? How do I know for sure?"
Taking this for face value is not a smart move in my opinion
The Pentecostal side of my family believes they experience the Holy Spirit speaking through members of their congregation almost every Sunday. The pastors regularly referenced these 'miracles' as irrefutable evidence that Christianity is authentic. Anyone who speaks out (me) is cast out of the congregation.
The real question is why no third party would respond. If the miracles were widely witnessed, why aren't there other historical sources writing about such amazing events? In the case of my former Pentecostal congregation, the greater population of writers and journalists never wrote of the 'miracles' because they were silly little rituals of a local cult.
At the time Paul was writing, few people outside the cult of Jesus bothered to waste their precious paper writing about Christianity. Those who did give it mention did so in passing, seemingly unfazed by the wild claims of cult devotees. Nothing to see here, folks, move on.
