*Atom-Smashing Power of Mind* (1949) is a New Thought Christian devotional essay by Charles Fillmore, co-founder of the Unity movement, arguing that physical death is not inevitable but a consequence of sinful (discordant) thinking that can be overcome through mental and spiritual discipline. Fillmore's central claim is that Jesus demonstrated a replicable science of bodily resurrection — not a unique divine miracle, but proof of a universal law accessible to anyone who masters right thinking. He contends that the human body is composed of inherently perfect elements that thought perpetually constructs or destroys: illness and aging trace directly to "harsh," disharmonious thoughts, while love, forgiveness, and constructive thinking can continuously renew cellular life. Fillmore reads the Easter narrative as historical fact *and* practical template, asserting that believers who follow Jesus in controlling their thoughts will literally resurrect their bodies rather than surrendering them to death. The essay's distinctive and provocative position is that mainstream Christianity has accepted death as natural and thus betrayed its own founder's teaching, which was that eternal embodied life is achievable here and now. Written for a Unity audience, it blends biblical exegesis with proto-metaphysical psychology, treating scripture as a manual for psychosomatic healing rather than a promise of afterlife.
