Christian Science
God is the only reality — infinite Divine Mind — and because Spirit alone is real, matter, sickness, sin, and death are forms of ‘mortal error’ to be healed by spiritual understanding of Truth.

What It Is
Christian Science is the religion founded by Mary Baker Eddy, built on the claim that God is the only reality — infinite, perfect Divine Mind — and that because Spirit alone is truly real, matter and its ills (sickness, sin, death) are not substantial things but forms of mortal error, a mistaken belief to be corrected by spiritual understanding.
Its central practice is healing: not faith that God might intervene in a real disease, but the realization that the disease was never real in divine Truth, so that recognizing one’s true spiritual being dissolves it.
It belongs to the same 19th-century American mind-cure ferment as New Thought, and shares the conviction that consciousness governs the body. But Christian Science is doctrinally distinct and was organized very differently — a closed, centrally-controlled church built around one authoritative textbook — which is why this Atlas treats it as its own tradition rather than a branch of New Thought.
Origins & History
Mary Baker Eddy (1821–1910). Long an invalid, Eddy dated her discovery to 1866, when she recovered from a serious fall after reading an account of one of Jesus’s healings; she took this as revealing a demonstrable “Science” underlying Christ’s cures.
- The textbook (1875). She set out the system in _Science and Health_ (later titled Science and Health with Key to the Scriptures), first published in 1875 after years of teaching and healing. It remains the movement’s doctrinal authority, read alongside the Bible.
- The church (1879). Eddy and a small group of followers — the sources give 26 charter members — founded The Church of Christ, Scientist in Boston in 1879, “to reinstate primitive Christianity and its lost element of healing.” The Mother Church and its Manual gave the movement a tightly centralized government. Eddy also founded The Christian Science Monitor (1908).
A note on the evidence 1 — the Quimby debt is disputed, not settled. Eddy was a patient of Phineas Quimby (1802–1866) in the early 1860s and improved under his mental treatment. Whether Christian Science is essentially Quimby’s system rewritten, or a genuinely independent development, became a bitter, decades-long controversy — a plagiarism charge was circulated in 1883, and the dispute was carried on by Quimby’s son and former patients. Scholars remain divided: some hold Eddy heavily indebted to Quimby; others (and the church) argue Quimby was a stimulus but that the finished theology — its rejection of matter as real and its Biblical, Christ-centered frame — departs sharply from his. The Atlas reports this as contested, not as a settled fact in either direction.
A note on the evidence 2 — Christian Science is not New Thought. Although both grew from the same Quimby-era mental-healing soil, Eddy repudiated the broader New Thought movement and forbade her followers to mix its teachings with hers. New Thought is open, eclectic, and decentralized; Christian Science is a closed, doctrinally fixed, centrally-governed church. They are cousins that became rivals — not the same tradition.
Core Teachings
God as Divine Mind. God is the one infinite Mind, Spirit, Principle, Life, Truth, Love — the sole cause and reality. (→ All Is One/Consciousness Is Fundamental.)
- The unreality of matter, sickness, and sin. Because only Spirit is real, the material world and its evils are “mortal error” — not created by God, therefore without true substance or power. (→ All Is One.)
- Spiritual healing. Healing comes by understanding this Truth, not by faith in a cure or by medicine; to know the disease’s unreality in Divine Mind is to be freed from it. (→ The Inner Creates the Outer, The Inner Creates the Outer.)
- The Bible read through Science and Health. Scripture is interpreted by Eddy’s text as its “Key,” with the two read together as the church’s sermon.
Key Figures & Texts
Mary Baker Eddy — discoverer and founder; author of Science and Health (1875).
- Phineas Quimby — her earlier mental-healing practitioner and contested influence (see A note on the evidence 1).
- Primary text: Science and Health with Key to the Scriptures (1875).
The Perennial Truths It Carries
Christian Science states a few Atlas truths at their most absolute. It carries The Inner Creates the Outer (healing through right belief / Truth) as its entire practice, The Inner Creates the Outer (the outer mirrors the inner — bodily condition follows mental state), and a maximalist form of All Is One/Consciousness Is Fundamental (consciousness is primary): not merely that mind shapes matter, but that matter is unreal and Divine Mind is All-in-all.
Where most of the lineage says mind governs reality, Eddy says mind is the only reality.
Lineage & Influence
Grew from: the same mental-healing current as New Thought — Mesmerism by way of Quimby — plus Eddy’s Bible study and New England Protestant frame. → Alongside / against: New Thought, with which it shares a root but from which Eddy deliberately separated (see A note on the evidence 2). → Seeded: a durable, organized church and a large body of testimonies of spiritual healing; its insistence on the unreality of matter pushed the “consciousness is primary” claim to its furthest reach within the lineage.
A note on the evidence 3 — the medical-care controversy (neutral statement of fact). Because the practice substitutes spiritual treatment for medicine, reliance on Christian Science healing in place of medical care has, in some documented cases, been associated with preventable deaths — including of children — and has produced real legal and ethical controversy, including prosecutions and debate over religious exemptions in U.S. law. This is stated here as a matter of historical record, neither to endorse nor to sensationalize; it is part of an honest map of the tradition.
