This essay explores conversion to the East African Revival as a way that Gikuyu women and men argued about moral and economic change. Rural capitalism in the 1930s and 1940s attacked the material basis of Gikuyu gender order by denying some men land. Familial stability was at stake in class formation: landless laborers could scarcely be respectable husbands. Rural elders and revivalists offered contending answers to the terrifying problem of gender trouble. Literate male elders at Tumutumu Presbyterian church used customary law and church bureaucracy to discipline young men and women. Revivalists, many of them women, talked: they confessed private sins vocally, cleansing themselves of sorcerous familial strife. Tumutumu’s debate over Revival played out as a contest between the oral politics of conversion and the bureaucratic power of church elders. Mau Mau continued the debate.
