The Yoruba word aladura, meaning ‘one who prays’, generally refers to a set of churches that formed a powerful religious movement among the Yoruba in western Nigeria during the first decades of this century. To date, there have been three main lines of interpretation which received general recognition: first, in form of a theological analysis (Turner, 1967); second, in a discussion of social protest (Mitchell, 1970); and finally, through the sociology of religion (Peel, 1968). In this article I propose to introduce another aspect of interpretation. Following the many passing remarks made by these authors in respect to the use of writing within the Aladura churches, I will read their accounts in terms of how people perceived and experienced the written word in the specific context of the Christian–colonial order and consider whether and how this experience has influenced people's actions and religious behaviour. In doing so, I am going to take up a theme which has become widely popular in the anthropological field under the heading ‘the consequences of literacy’.
