This study of the religious impact of Christianity in West Africa concentrates on the role of Africans as the principle agents in the spread of the religion and on the significance of Africn meterials. Previous studies have mainly focused on the organization of the missionary effort in Europe and America, with African Christianity seen as a direct consequence of external developments. Author Lamin Sanneh disputes this theory by paying close attention to the adaptation of the religion in African societies and to parallels and exigencies in local traditions.
