The existence of a widespread religious phenomenon in Africa appearing under many names, in corporate manifestations as new groups and in individual form as new prophets, is evidenced in many ways. Even the most casual observer driving through a large African town cannot fail to notice the succession of exotic names on sign boards or to meet a white-robed religious procession, and if he tries to trace the bell-ringing, drumming, and chanting that fill the night air for hours on end the chances are that he will be led to one of these sign boards and to some humble structure filled with tireless worshippers. Occasionally the bizarre behaviour of a prophet or “sect’ provides material for the journalist seeking sensation, or leads to an appearance in the police courts, or even to military action, as in Northern Rhodesia in 1964 against the Lenshina movement. Strange churches apply for membership of Christian councils, and ministers and missionaries are perplexed when some of their members secure spiritual help from a semi-literate prophet, or transfer their allegiance to an unknown church with an outlandish name.
