Jon Walker in his book, In Visible Fellowship: A Contemporary View of Bonhoeffer’s Classic Work:  Life Together writes in chapter 28 about the “Ministry of Authority.” Dietrich Bonhoeffer wrote…

Every cult of personality that emphasizes the distinguished qualities, virtues, and talents of another person, even though these be of an altogether spiritual nature, is worldly and has no place in the Christian community; indeed, it poisons the Christian community.   

Walker writes that The Big Idea is…

The question of trust, which is so closely related to that of authority, is determined by the faithfulness with which a man serves Jesus Christ, never by the extraordinary talents which he possesses. We have been given the authority to love one another.  

Walker added:

Bonhoeffer notes that New Testament leadership is not defined by “worldly charm” or “brilliant attributes.” In fact, the apostle Paul, in effect, tells Timothy, that leadership is as leadership does (1 Timothy 3:1-7). The true test of leadership is in service to others.

…Jesus teaches us that the only way to lead others is to serve them. Menial was not beneath Jesus. He always placed the needs of others above his own, even as he approached his own death.

…To be like Jesus…Jesus made authority in the fellowship dependent upon brotherly service. Genuine spiritual authority is to be found only where the ministry of hearing, helping, bearing, and proclaiming is carried out.
