This paper explores the use of the Chewa and Nyanja concepts of mbumba and nkhoswe in Central Africa and Southern Africa as interpretive tools for an Anglican ecclesiology and theology of leadership. Following an exposition of these two concepts, it conceptualizes mbumba as a diocese, and bishops as nkhoswe deriving from Christ as Nkhoswe par excellence. These two concepts entail critical values including responsibility, accountability and mutuality, which can be used as a model to enhance the relationship between a diocese and bishop. Conceptualizing a diocese as mbumba and the role of a bishop as that of nkhoswe has the potential to enhance missional practice in Central and Southern Africa.
