*The Revealing Word* (1959) is a metaphysical glossary by Charles Fillmore, co-founder of the Unity Church movement, presenting definitions of spiritual and biblical terms from the perspective of New Thought Christianity. Its central argument is that Scripture, language, and the human body all encode hidden spiritual realities: Hebrew names carry literal metaphysical meanings, anatomical features symbolize spiritual faculties, and familiar biblical objects or concepts correspond to states of consciousness. Fillmore consistently reframes theological language in quasi-psychological terms — nations are "aggregations of thoughts," night is "human understanding," the neck is "the seat of the power faculty" — positioning the individual mind and body as the true theater of spiritual experience. A distinctive claim running throughout is that invoking sacred names (particularly "I AM THAT I AM" and the name of Jesus) has direct, demonstrable power to expand consciousness and produce physical healing. The text also draws loosely on late-19th-century vitalist and electromagnetic ideas, describing a "nerve fluid" propelled by God through the body as a literal spiritual force. Someone interested in the history of New Thought, metaphysical Christianity, or the esoteric interpretation of the Bible would find this a primary-source exemplar of that tradition; those seeking orthodox theology or rigorous biblical scholarship would not.
