Dignitatis Humanae—the Declaration on Religious Freedom—was among the most debated documents of the Second Vatican Council. Significant divisions among bishops, particularly between those from countries with established Catholic majorities and those experiencing religious pluralism, resulted in more votes against it than other conciliar documents. Therefore, it was issued as a separate declaration, reflecting the complexities of its formulation. Ultimately approved thanks to, among others, the witness of bishops from the Communist East, the declaration continued to cause controversy long after the Council due to traditionalist pushback. The original placement and the controversies prove that religious freedom is fundamental to understanding how Catholics are to be the Church in the third millennium. Sixty years after its publication, as global Catholicism has experienced significant geopolitical, cultural, and religious shifts, Dignitatis Humanae deserves renewed consideration. This presentation will explore the ecclesial vision embedded within the declaration, examine its implementation—including subsequent responses such as the International Theological Commission's "Religious Freedom for the Good of All"—and consider how it can inform the development of the Church's self-understanding.
