In times of social crises, Public Religious Pedagogy is emerging as "a new paradigm in the field of Religious Pedagogy" (Manfred L. Pirner). This paper aims to strengthen this approach through a critical review. To achieve this, the theoretical foundations of Public Religious Pedagogy will be examined more closely in order to investigate their strengths and weaknesses. The result of these considerations is to expand historical sources and interdisciplinary references of Public Religious Pedagogy: It is necessary to interpret the concept more broadly. Finally, this article argues in favour of a "critical" and "prophetic" Public Religious Pedagogy.
