This is an anthropo-theological study of sexuality among modern African Christians. Thus, the study examines the concept of sexuality among modern African Christians by seeking to extend the frontiers of knowledge on the topic. It is observed that African Christians carry two identities; Christianity and traditional culture-bearer. These have far-reaching effects on the people socially and religiously as the two have in it, the concept of moral rules. Data indicate that African societies, at various points, construe sexual relationship as a sacrosanct factor in their image of an ideal society, and a respectable phenomenon, which every member of the society must adhere to the rules guiding it. The study notes that on one hand, modern African Christians are faced with the challenge of expressing sexuality and its different colorations within the confine of Judeo-Western Christianity bequeathed to them by Western missionaries, and on the other hand, they are confronted with expression of sexuality within their traditional cultural norms. Methodologically, the study uses documented ethnographic data from anthropological studies of some notable African societies and biblical exegesis.
