That means that the period with an interim is likely to be turbulent. One person in my current congregation likened it to working with a psychologist. Another part of the reality is that the effective interim minister is not necessarily liked. So interim ministry is a ministry where one changes congregations frequently, is involved in high stress issues and is often disliked. It is like having three years of congregational experience packed into six months.
Situations change radically in very short periods of time.
The required analysis of the congregation as a system is intriguing. As well, for myself, one of my challenges is dealing with conflict. The interim minister needs to be self-differentiated in the sense that this person needs to make their own decisions, needs to have their own vision, needs to have stability from within, rather than being tossed and turned by the vagaries of congregational or other individual's moods and attitudes. Interim ministry is an exciting time in the faith journey of a congregation. Like Moses, the interim must have a sense of God at work.
