This study into “Christian nominalism in church membership: A case study of the church in the town of Bunia in the Democratic Republic of Congo” is an attempt to describe one of the major problems in the growth of the Christian population in the Bunia churches in particular and the African church in general. The purpose of this study was to create awareness among church leaders of the challenges of nominal Christian faith in their respective church memberships, to examine the correlation between their awareness or lack of awareness of the problem of nominalism in their churches and the alleged nominal faith of their church members, and to suggest practical steps for pastors in Bunia to effectively address the challenges of Christian nominalism in order to bring transformation in the life and ministry of their respective local churches.
