Father Ron Rolheiser is ecumenically recognized as one of the most important voices in Christian spirituality today. His career has spanned fifty years. He has served the Church as a theologian, educator, and priest in the religious congregation of the Oblates of Mary Immaculate. This volume offers ten essays that dare to imagine what the future might hold for Christian spirituality and Christian spiritual formation. They are written by Catholic and Protestant scholars and practitioners, both men and women. They explore the contemporary landscape of contemplation, community, the mystical life, and some of the many spaces in which spirituality intersects (such as spirituality and theology, sexuality, gender, and aging). Fr. Rolheiser has devoted his life to practicing and teaching others to practice a thoughtful and robust spiritual life. He envisioned and helped to develop a Christian spirituality institute which is now flourishing at the Oblate School of Theology in San Antonio, Texas. His friends and colleagues have come together to honor his life’s work by contributing these essays, sharing their unique perspectives.
