Mark 10:42-45 — Jesus's leadership model: "You know that those recognized as rulers of the Gentiles lord it over them... but it is not this way among you." The greatest must be servant; the first must be slave of all. Pastoral abuse happens when leaders adopt CEO mentality — protecting their vision, reputation, and authority instead of serving. Signs: demanding allegiance to the leader rather than to Christ, silencing criticism, creating distance/hierarchy, using authority for personal benefit.
