Few people have any extensive knowledge of the life and witness of the Protestant churches in the former Portuguese colonies of southern Africa. Yet these communities of faith played a significant role in the liberation struggles that led to the independence of both Mozambique and Angola and subsequently to the independence of Zimbabwe and the ending of apartheid in South Africa. In Mozambique, Eduardo Mondlane emerged from the Swiss Mission to become the first president of the Mozambique Liberation Front (FRELIMO). This book examines Mondlane's role in challenging the churches both in Mozambique and globally to support the struggle for independence through a renewed understanding of the missio Dei, God's liberating mission in the world. Mondlane maintained a strong connection with the World Council of Churches and was a key player in bringing about its Programme to Combat Racism after the 1968 Assembly in Uppsala before his assassination in 1969. This connection was to have important implications for the WCC's complex relationship with Mozambique and its Protestant churches following independence.
