Redeeming Reason shows how faith and rational inquiry belong together, challenging secular autonomy and fideism. Eduardo J. Echeverria-Roman Catholic Kuyperian-engages Bavinck, Kuyper, and Vatican II on nature and grace, common grace, natural theology, ecclesial unity, and Christian philosophy. Through ecumenical essays, he defends realism about truth, acknowledges sin's noetic effects, and calls for cultural renewal under Christ's kingship. Rigorous yet accessible, this volume equips scholars, pastors, priests, seminarians, and students to think faithfully with confidence.
