The study explores the relationship of the evangelical movement in South Africa with the ecumenical movement. The focus of the latter was taken as organizationally embodied in the South African Council of Churches. The time period 1960 - 1990 was chosen for the study as this was a period of great socio political upheaval and testing for the churches. This was also a period that marked both the escalation of the struggle against apartheid as well as the accentuation of the differences that churches had among themselves as they were confronted with the reality of apartheid. The author believes that the trying times in view, 1960 -1990; best clarify the lessons that could be learned by both evangelicals and ecumenicals. The trials of this period presented the churches of South Africa unique opportunities for growth in the midst of intense struggles. The study seeks to unpack theological lessons that would perhaps not be as easy to see at a different time, for example under conditions of peace and quiet. / Thesis (M.Th.)-University of KwaZulu-Natal, Pietermaritzburg, 2007.
