Early in 1965, I started extensive field research on the African Initiated Churches (AICs) in Zimbabwe. I first had to drive into Zion City, the Zion Christian Church (ZCC) headquarters of Bishop Samuel Mutendi, situated at Mutarara in the Bikita district. I arrived unannounced and completely unknown to the bishop. Yet he was not the least bit disturbed by my unexpected arrival.
Marthinus Louis Daneel (Sun,) studied this question.
