The Oran Mór Institute is a home for contemporary Celtic theology grounded in wisdom, attentiveness, and lived meaning. Drawing on the Celtic vision of Oran Mór—the Great Song—the Institute explores reality as infused with embedded meaning rather than governed by fear, magic, or control. Its work integrates Celtic cosmology, Christian faith, ethical reflection, and spiritual practice, holding Jesus as a central wisdom teacher who embodies and sings the Great Song of creation.
The Institute is committed to a post-secular spirituality that is intellectually serious, morally grounded, and deeply humane. It emphasizes dignity, right relationship, contemplative practice, and community-based formation. Through writing, teaching, and shared reflection, the Oran Mór Institute seeks to translate ancient Celtic wisdom into forms that speak clearly and credibly to contemporary life.
Gregory Gronbacher, Ph.D. | Founder & Director
Gregory’s philosophical and theological work is grounded in Celtic philosophy and in contemporary forms of Celtic spiritual ecology that emphasize interconnectedness, attentiveness to the natural world as a spiritual touchstone, and the presence of embedded meaning within lived experience.
His work approaches spirituality as a reflective practice concerned with existential and normative questions—how meaning is discerned, sustained, and embodied within an interconnected world.
