The second half of the 19th century was characterised by the spread of Christian ethos in Southern Africa. This state of affairs also permeated the Zimbabwean soil, and in the Presbyterian Church of Southern Africa in Zimbabwe (PCSA) missionaries disseminated Reformed teachings, among other things, to proclaim the gospel of Christ. This article argues that Presbyterian teachings influenced the socio-political and economic development of Zimbabwe. It is a historical analysis illustrating how Reformed theological perspectives influenced the socio-political and economic development of Zimbabwe through the work of the PCSA. It is not the intention of this article to get into theological debates but to show the impact of Reformed influences, mainly through John Calvin, on the expansion of Presbyterianism in Zimbabwe.
