Paul regulates ministry in various ways. The very fact that he tells us to keep our eyes transfixed on those who walk according to the example he gave suggests that there were people who didn’t (Philippians 3:17). There were men in positions of spiritual leadership that did not live up to the expectations in Scripture. These men are not only to avoided, but are personally called out by other apostles, Peter most notably, for their habit of being domineering. 1 Peter 5:3 is a warning to all elders they must discharge their leadership duty in love, “not domineering over those in your charge, but being examples to the flock.” You cannot be domineering, and a good example. The two are incompatible. This is good for both flock and shepherd alike.
