This paper explores the challenge of rethinking the forma ecclesiae in a contemporary context marked by distrust in institutions, a crisis of belonging, and the erosion of authority. Drawing on the framework of Public Theology developed by Breitenberg and Thiemann, the paper identifies key pathways for renewing ecclesial structures and the exercise of authority, essential for constructing an ecclesiology informed by gender perspectives. Proposed Framework: 1. Moving beyond traditional church models: exploring alternatives and the prophetic necessity of a collective (institutional) subject. 2. Foundations for renewal from Public Theology: posture, contextual engagement, and collective performance. 3. Directions for reforming the forma ecclesiae today: conversation, pluralism, extroversion, "just church," transcendence, and freedom. 4. Rethinking auctoritas through a gender lens: accountability, empowerment, inclusive authority, and the voice of an ecclesial "We" in society.
