Abstract

McCullough is an assistant professor of practical theology and spiritual care at the University of Toronto. He offers a detailed and engaging study that connects early modern mysticism with the foundations of modern psychotherapy. By positioning the seventeenth-century German philosopher and Christian mystic, Jacob Boehme (1575–1624) within a longer intellectual lineage reaching back to Saint Augustine and forward to C. G. Jung and transpersonal psychology, McCullough describes the relations between theology, metaphysics, and the psychology of the soul. The central argument of the book is that Boehme's original theological approach—rooted in his reflections on divine duality, human suffering, and spiritual rebirth—introduced key concepts in depth psychology. Drawing on Boehme's writings alongside later developments in existential and analytical thought, McCullough reconstructs how mystical experience and self-knowledge became connected with the Western understandings of the psyche. The work situates Boehme not only as a pivotal figure in the Christian mystical tradition but also as one who redefined spiritual introspection in ways similar to contemporary therapeutic perspectives. McCullough's comparison to Saint Augustine is particularly engaging. By tracing Augustine's notions of dream analysis and perception of the soul, as antecedents to Boehme's spiritual psychology, he establishes a coherent scholarly continuity between late antique and early modern ideas. This Augustinian dimension provides essential grounding, showing how Boehme's insights were both a continuation and radical transformation of Christian ideas about the soul's journey toward divine union. What distinguishes McCullough's study is its analytical clarity and the refusal to romanticize mysticism. Rather than reading Boehme through an anachronistic psychological lens, he situates him within a complex historical context, exemplifying his relevance to modern therapeutic discourse. The book stands as a significant contribution to the growing discourse on the intersections of spirituality, mysticism, and psychological healing. It will appeal to scholars of Western esotericism, early modern theology, and the intellectual history of psychology. It offers a compelling argument for Boehme's lasting significance in the evolution of spiritual self-understanding.
