Luther and Calvin, the great reformers of the sixteenth century, are remembered for their writings and theological debates, but do we think of them as great missionaries? Can we learn from them for mission work today? The Reformation had a defining and far-reaching impact on the western world and beyond. It shaped the development of Europe over the next 500 years. It not only touched on church life and key doctrinal issues but had implications in terms of ethics, the birth of liberal democracy, education, the arts, science, the economy and much more. This all evolved as part of Calvin's and Luther's evangelistic vision. With such a legacy, this vision is worth your attention.
