This exploratory and programmatic article aims to assess the degree of Protestantism’s participation in the cultural revolution of the 1960s, with a particular focus on the founding of the Séminaire de culture théologique de Lausanne in 1962 providing a textbook case. An analysis of the context and, most significantly, the sources (such as journals, notebooks, and newspapers) created within Protestant circles in French-speaking Switzerland uncovers distinct theological enthusiasm. In the aftermath of World War II, the group aimed to reconsider Christianity’s role in society by democratizing theology and removing clericalism from Protestantism through the establishment of adult education centers. Thus, the Protestant churches spread out their own system of authority, providing space for the emergence of the “May 1968” generation.
