This paper examines the public theology of the Waldensian Church—later the Union of Methodist and Waldensian Churches in Italy—within the context of post‑World War II Italy. It analyzes how the Waldensian Church responded to the challenges posed by a newly established democracy, and how it gradually came to understand itself less as a "minority" and more as an active "component" of the Italian democratic public sphere. The paper focuses on several crucial debates, beginning with that on freedom of religion, which evolved from a position of strict laïcité à la française toward a richer notion of religious pluralism, navigating the transition from a failed secularization to post‑secularity. Within this broader framework, the paper reconstructs the theological conversations sparked by major transformations in Italian society, such as the legislation on divorce and abortion. It also considers the failed encounter with the Comunità di Base and Cristiani per il Socialismo, highlighting the main differences in their respective theological frameworks.
