The fault lies with the men who made the decisions to put the new believer on the stage and elevate the young Christian to leadership. In fact these men were abused. They were asked to perform for the benefit of the men who made the decisions. In the first case to fill and event in the last case to trophy a successful business man in a high profile ministry position. There was no thought given to whether these men were ready or the impact on their spiritual formation. It was a bit like giving a 4 year old a chainsaw and telling him to cut down a tree.
Paul is really clear about this. In 1 Timothy 3:6, he warns Timothy not to appoint new converts to positions of authority. In 1 Timothy 5:22 he tells Timothy that if he places one in authority too soon he bears the guilt of the mess they make and the sins they commit. It seems like more and more we in the Church are ignoring Paul.
