What tantur does

Tantur Ecumenical Institute is a religious and educational institute founded in 1972 by Pope Paul VI and operated under the stewardship of the University of Notre Dame, situated on a 40-acre hilltop campus between Jerusalem and Bethlehem, Israel. The institute delivers continuing education programs for clergy, religious leaders, academics, church groups, and lay individuals seeking theological study, spiritual formation, and pilgrimage experiences in the Holy Land. Core offerings include a portfolio of structured sabbatical programs ranging from one week to three months in duration (Easter Encounter, Five-Week Summer, Six-Week Fall, Three-Month Fall), a Week of Christian Unity Program, an eight-day Ignatian Spiritual Retreat, customized pilgrimages and conferences for groups, a Tuesdays at Tantur monthly lecture series, and a residential Research Opportunities program for junior and senior scholars. Supporting resources include the Tantur Library and a growing Video Resources Library of lectures, reflections, and discussions.

The business model is a direct-delivery educational and hospitality model with no intermediaries. Tantur charges all-inclusive one-time program fees per participant ranging from $600 (non-residential eight-day retreat) to $16,658 (single-room three-month program), covering accommodation, meals, lectures, and excursions; payments are processed by credit card or wire transfer to Notre Dame. The institute generates revenue solely through these participant fees plus group hosting arrangements, with no disclosed external funding, advertising, or commercial revenue streams. Customer acquisition is event-driven (scheduled program dates) and community-led, leveraging a 5,000+ alumni network spanning Orthodox, Protestant, Anglican, and Catholic participants since 1972, alongside partnerships with Notre Dame, the Chemin Neuf Community, Taizé, the World Council of Churches, and the Dicastery for Promoting Christian Unity. A pending Rector succession with an anticipated start date of early summer 2027 represents the most significant upcoming organizational change.
