A mostly helpful guide to wisely managing your relationships. The author seems to have people in similar positions of high level leadership like himself, as it leaves little nuance for lay leaders in churches or even just general life and business. It was insightful in some of its principles, but if the categories are taken too far, I think serious damage could be done to witness and testimony. In hindsight, I know what it feels like to to be categorised in a “lower” category, at times by people who neglected their role and responsibilities to aim for working others in “higher” categories. When you know it’s happening, you move on yourself, when you diagnose in retrospect, it can be hurtful and condescending. In pastoral ministry, I’m not convinced you get options of such categories in the definite terms this title suggests, but the broader understanding is still important to keep in the back of one’s mind, it does not belong at the forefront of forming or maintaining or committing to relationships.
