This article considers the contribution of the Mindolo Ecumenical Foundation to the political and socio-economic development of Zambia. First, the introduction and growth of Christianity in the mining areas of the Copperbelt are explored. Next, the article traces the formation and development of the Mindolo Ecumenical Foundation. In the third place, it analyses the role played by the Mindolo Ecumenical Foundation in the politics and development oj Zambia during the first decades of its formation, including its participation in Zambia's struggle for independence. After political independence, the foundation continued to fulfil a major part in facilitating reconciliation between blacks and whites. The article argues that the participation of the church in God's mission in the world cannot be divorced from socio-economic and political realities. There are many studies about missionaries and their activities in Zambia. (1) However, very few of these concentrate on the work of the missionaries in the Copperbelt province and on the activities of the Mindolo Ecumenical Foundation in particular. (2) The Mindolo Ecumenical Foundation (MEF) is one of the Christian institutions that developed a critical view of colonial power structures in pre-independence Zambia. (3) This article considers the origins and development of the MEF and its contribution to development and the growth of Christianity in Zambia. The origins of MEF can be traced back to the struggles of the African miners and their families to access welfare and educational facilities and to the initiative of the mission church to respond to these needs. The expansion of mines in Zambia's Copperbelt province led to rapidly increasing rural-to-urban migration. People from the rural parts of Zambia and neighbouring countries in southern Africa moved to the mines, where they faced many challenges. First, there was the loss of family ties and of African cultural values due to their exposure to Western lifestyles. Second, there was segregation of whites and blacks in the mines. The colonial government promoted a racial policy called "the colour bar" under which whites and blacks were not allowed to mix socially. (4) Blacks in the mines got less pay than their white counterparts while doing the same jobs. Whites went to good schools, exclusively for them, while blacks had to attend poor-quality schools. The colonial government had no proper welfare and education policy for blacks in the Copperbelt. (5) It was for this reason that the mission church took the initiative to provide education and welfare facilities for African miners and their families. Morrow records: There was a move in 1931, stemming from the Merle Davis Commission of that year, to commence systematic mission work on the Copperbelt. However, it was not until 1933 that the London Missionary Society, the main Protestant mission society working in the area of Northern Rhodesia that supplied much of the labour of the Copperbelt, followed the advice of the International Missionary Council's Commission of Enquiry, and made an appointment to the Copperbelt. (6) In 1932 the International Missionary Council (IMC) sent Merle Davis and a team of sociologists to survey the Zambian Copperbelt to define how the church could do holistic mission there. (7) The survey report recommended the strengthening of ecumenism in the area. In 1934, the London Missionary Society (LMS) founded the Mindolo Mission in the Copperbelt. Mindolo mission station "became the centre of much of the Copperbelt missionary work." (8) The Rev. R.J.B. Moore, the founding missionary of Mindolo mission station, raised a strong voice of protest against the injustices, perpetrated by the colonial government and authorities in the mines. In 1935, African workers in the mines on the Copperbelt went on strike to protest against tax increases. Colonial government forces shot dead a number of African miners. …
