Another charge I served part time and helped move to minimal ministry had a conflict a few years earlier. The person appointed by presbytery to help resolve the conflict choose to support one side and the congregation split in two. It was a small congregation before so it became unable to support even part time ministry.
My experience with presbyteries found many presbyteries have leadership that puts existing relationships among leaders or political ideologies above doing what congregations need.
Interims are often splitters ... divine?
Alas respect the bits ... AD onus? Culp ability or gullibility ... C Birds? Observing the waters ...
