The Unitarian Theological Interpretation of the Immortality of the Soul

This thesis explores the concept of the immortality of the soul within the framework of Unitarian theology, integrating philosophical, theological, and contemporary scientific perspectives. Drawing upon both classical philosophical traditions and Christian theological reflections, the study investigates how the belief in the soul’s continuity after death has evolved and how it is interpreted today, particularly within Unitarian religious thought. The dissertation adopts an interdisciplinary and hermeneutical approach, with a particular emphasis on the existential and ethical implications of the doctrine of immortality. Rooted in the dignity of human reason and moral development, Unitarian theology emphasizes a rational faith dialogue over rigid dogma. The research highlights how this theological tradition addresses the question of immortality not merely as a metaphysical hypothesis but as a deeply human concern shaped by grief, hope, and the longing for transcendence. The study revisits classical views from Plato to contemporary neuroscience, and examines the intersections between consciousness, death, and spiritual continuity. Special attention is given to the theological reinterpretation of body-soul dualism and the notion of eternal life not only as a future state but as a present spiritual reality rooted in the ethical pursuit of goodness and love. The paper concludes that belief in the immortality of the soul, when approached through a Unitarian lens, is not only compatible with modern thought but also offers meaningful responses to contemporary existential questions. It invites believers and seekers alike to consider immortality as a living hope grounded in personal transformation and divine justice.
