This work is an analysis of Mambila religion based on fieldwork in Somié village, Cameroon. An ethnographic and historical introduction to the Mambila is followed by an account of their religious concepts. It is argued that, despite their adherence to Christianity (and to Islam), traditional practices continue to be of great importance in everyday life. In order to examine traditional practice descriptions are given of divination and oath-taking rites. Translated transcripts of the different forms of the sua-oath form the empirical core of the thesis. The transcripts illustrate the way that Mambila experience and understand the meaning of sua. Descriptions are also given of the sua masquerades. Finally I examine problems inherent in the analysis of non-literate societies lacking a reflective tradition, and in particular, societies lacking precise, structured religious concepts. This allows for discussion of resulting implications on the relationships between religion, politics and ‘symbolic power.’
