Religion has no place in business leadership today (other than as a contribution to diversity). I contend, however, that it is essential that we undertake a secular study of role of religion in historical leadership if we are to fully understand the differential voice. The differential voice does not have a religious basis, but it fulfils a function that has been almost exclusively the domain of religion for at least the last 10,000 years. By studying how religion underpinned power and functioned as the agent of social cohesion, we can understand how to engage our followers with our nonreligious differential voice.
