There is such a thing as church discipline....it’s a biblical process detailed in scripture.
“There is such a thing as church discipline....its a biblical process detailed in scripture”
You are right, but Camping removed himself from the discipline of his church by claiming that the churches were filled with heretics and that the Church Age was over in 1988. Therefore, he is exempt from any discipline since he has no allegiance to any. However, Camping, if he is still alive, ought to repent to God for deceiving naive and desperate people and then apologize to Christians everywhere for his hubris and cult like dominance.
Most reputable Christian leaders, even those with very large ministries (Franklin Graham, Max Lucado, et. al) have accountability partners who they can talk with and run ideas past, and these people can tell them if they're 'going off the reservation' scripturally. They put themselves under authority of fellow believers to help them stay the proper course in their walk with Christ. Many of them also have pastors and churches that they are a part of who have authority over them.
Most nutjobs or cult leaders, like Camping, don't have anyone in authority over themselves, setting themselves up as the highest authority. In their minds, the only one they answer to is "God".
(Note: I put "God" in quotes because a lot of times their ideas are so half-baked and strange that the true God had absolutely nothing to do with it, even though they give Him 'credit' for it.)
