Our church began to have struggles where people were complaining, attendance was lowering and the tithes and offerings were less each week. I turned to my uncle who was an evangelist and dealt with many pastors all over the country. He said without hesitation, there is someone in your leadership that is sewing seeds of discord and turning the people against your Pastor and the mission of the church. He also warned to look closely at the other Assistant Pastors, deacons, finance committee and Bible Study leaders because that is usually the problem.
There are times when a Bible study group of adults are actually acting more like their own church than a part of the church body and begin to take steps to take over and run the church themselves. I have seen ministry leaders in charge of church finances who have managed to take over a church to support their own personal non-profits outside of the church. People can be fueled by individuals in the church to pursue their own mission instead of the mission of the church.
There are also the lay leaders who are involved in a lot of different areas to be a help but it is also a way to get in control and have things done the way they would prefer to have them done. Some times it is a parent who is demanding how they want things to be in the ministry area their child is involved or just angry in general. I have seen deacons or groups within the church that are more committed to their own control of areas of the church by trying to manage the Pastors and staff instead of focusing on the mission of the church.
