Thomas Moore's life journey, deeply embedded in the preparation for the priesthood, albeit not culminating in ordination, has undeniably shaped his philosophical outlook. Those formative years instilled in him a profound appreciation for self-denial, simplicity, and contemplation. Moore views the Bible as a "compendium of insight into the nature of the soul," underscoring the significance of ritual and symbolism, elements that are integral to the Catholic tradition. He emphasizes that spirituality is nurtured through communal worship and dedicating time to religious observance, principles that resonate with Christian doctrine.

Moore’s interpretation of the soul dovetails seamlessly with Christian theological concepts and the rich symbolism found in biblical narratives. He draws upon the imagery of Jesus at the River Jordan, poised for baptism, as a metaphor for immersion in the "stream of events"—the ever-flowing river of time and destiny where each individual must find their place. The Gospels, with their evocative stories, serve as a source of inspiration and guidance, offering insights as one navigates the complexities of life. For Moore, the structured teachings, rituals, and stories within Christianity offer boundless opportunities for contemplating the soul’s mysteries.

While Care of the Soul might initially appear to be a "self-help" manual, Moore clarifies that it is better described as a journey of "self-discovery." With his background as a psychotherapist, Moore shares anecdotes illustrating how soul analysis has facilitated personal growth among his patients. However, he is careful to point out that his approach is not about "curing" individuals. Instead, Moore advocates for a paradigm shift in perceiving the inner life—one that fosters understanding, acceptance, and wisdom. This reflective exploration encourages a deeper connection with the soul, aligning closely with Christian values and the enduring quest for spiritual enlightenment.
