In the shadow of empire: Josef Schmidlin and Protestant-Catholic ecumenism before the Second World War

This article examines the life and ideas of Josef Schmidlin, the founder of Catholic missionary science' and the most influential German Catholic missionary theorist of the first half of the twentieth century. An admirer of the German Protestant missionary theologian Gustav Warneck, Schmidlin often appears in the historiography as a forerunner of the Protestant-Catholic ecumenical collaboration that emerged after the Second World War. Yet a close examination of his writing reveals a vigorous critic of Protestantism and the Protestant ecumenical movement. A sceptic of transnational missionary organizations, he remained a firm supporter of the German nation and imperial project. This article gestures towards both the continuities and the discontinuities between the early attempts at fostering confessional cooperation between Protestants and Catholics and the later iterations. It also examines how nineteenth-century entanglements between missions and empire shaped the ideas of Catholic missionary theory during the interwar years.
