Mary Baker Eddy’s life and teaching emerged in the specific religious and cultural landscape of nineteenth‑century New England, a region marked by revivalism, Protestant moralism, and an expanding market of alternative spiritualities. Born in 1821 in New Hampshire, Eddy lived through the Second Great Awakening and its aftermath, when itinerant preachers, new sects, and experiments in healing and spiritual inquiry were commonplace in the United States. This social field — in which conventional Protestant churches shared space with mesmerism, spiritualism, and the burgeoning “Mind‑Cure” currents — provided both language and institutional models for a new religious movement that would emphasize the role of spiritual understanding in daily life, and specifically in healing bodily illness.
A concrete turning point in the story that Christian Scientists tell is the episode of 1866 in Lynn, Massachusetts, when Mary Baker Eddy reported recovering from a serious fall and a subsequent chronic condition through what she described as the discovery of a spiritual law of divine Mind. Historians note that Eddy’s claims of personal healing are central to the tradition’s self‑understanding; religious studies scholarship situates those claims within broader American practices of experiential authority and healing ministries in the same period. The distinction is important: adherents present the Lynn incident as revelatory in a theological sense, while historical critics treat it as an originating biographical event that must be read alongside social and cultural influences.
Eddy’s writings and teaching began to cohere into a distinct textual base with the publication, in 1875, of Science and Health with Key to the Scriptures. The book offered a systematic interpretation of the Bible through a metaphysical lens that identified matter, disease, and human suffering as forms of error to be corrected by understanding God as the only reality. Science and Health therefore functions for followers not merely as commentary but as an interpretive key to Scripture; it is the most cited printed work in Christian Science services and has been revised and reissued across editions since 1875.
Institutionally, 1879 is the canonical founding date attributed to the Church of Christ, Scientist. In that year the movement moved from informal classes and reading groups to a denominationally titled body that established congregations, Sunday services, and the protocols for membership and church governance. The creation of a denominational structure reflects a common pattern among nineteenth‑century American movements that moved from charismatic teaching to organized religious life.
Several concrete institutional developments in the late nineteenth century mark Christian Science’s expansion. The First Church of Christ, Scientist in Boston — often referred to as the "Mother Church" — purchased land and completed the earlier church building in the 1890s; a larger extension was added in the first decade of the twentieth century. The Mother Church became the administrative and symbolic center of the movement and offered an architecturally visible presence in Boston. Another specific milestone was the founding of The Christian Science Monitor in 1908, a daily newspaper intended by Eddy as both a witness to the movement’s public engagement and a forum for journalism shaped by Christian Science values.
From the outset Christian Science sat at an intersection of continuities and tensions. It is in continuity with Protestant emphases on Scripture and on a conversion experience, while differing sharply from many Protestant theologies in its metaphysical denial of matter as ultimately real and its insistence that correct thought — rather than sacramental or biomedical means — effects healing. Internally, tensions quickly appeared between centralized authority and charismatic teaching: as the movement institutionalized, questions arose about who could interpret Eddy’s texts, who could lead congregations, and how the Church would respond to divergence among teachers. These tensions would play out in controversies and schisms in the early decades of the twentieth century.
Scholars usually locate Christian Science within the family of American new religious movements and the broader matrix of “Mind‑Cure” or metaphysical therapies; comparison clarifies both resemblances and differences. Unlike many contemporaneous spiritualists, Christian Science anchors itself in a radically reinterpreted reading of the Bible and claims a single founder whose writings remain canonical. At the same time it shares with New Thought and other healing movements an emphasis on the efficacy of mental states and prayer for physical well‑being.
The movement’s early spread combined itinerant lecturing, printed tracts, and the training of students in class settings. Eddy’s own institution—variously called a college or class—trained teachers who established congregations across the United States and abroad. By the turn of the twentieth century the church maintained organized Sunday services, chapter meetings for study, and a structure for licensing practitioners who professed competence in Christian Science healing. These developments testify to an early and deliberate effort to create a durable institutional presence, rather than a loose network of fellow seekers.
Externally, Christian Science quickly attracted both admiration and criticism. Admirers praised its reported healings and social arrangements for women’s leadership (Eddy was a female founder at a moment when women’s public religious authority was exceptional). Critics — including medical professionals and some Protestant clergy — raised questions about the rejection or deemphasis of medical intervention. Legal and public health conflicts would become recurrent across the twentieth century, as courts and state authorities sometimes confronted the tension between religious freedom and obligations to provide medical care, especially in cases involving children.
By the early twentieth century the movement had established key inscriptions in American religious life: a distinctive theology codified in a principal book (Science and Health), a denominational structure (the Church of Christ, Scientist, founded 1879), a central institution in Boston (the Mother Church and its extension, completed in the 1890s–1906), and a media outlet (The Christian Science Monitor, founded 1908). These concrete facts ground narratives about a charismatic origin that then moved to institutional consolidation — a pattern visible across many modern religious movements.
Origins, then, are best read as a conjunction of personal experience, textual production, and institutional invention. The historical scholarship highlights the cultural resources that made Eddy’s ideas intelligible and compelling to her contemporaries; the tradition’s own accounts stress revelation and spiritual discovery. Both perspectives, when held together, illuminate how Christian Science emerged in the United States in the late nineteenth century and became a distinctive, organized voice among modern religions.
