Although servanthood is a very important biblical concept for leadership, according to Richard Higginson, the role of servant “is not reserved only for those who are leaders. Christians in general are “servants of God” and are expected to serve other people.” Moreover, to be ethical in a servant style is not distinctly Christian; leaders who are not Christian can nonetheless operate as servants. The term servant does not in itself have a religious connotation. Yet under theological auspices, a distinctly theological sense of servant leadership can be understood and practiced. I contend that such servant leadership is something more than the notion that has been popularized.
