Christian Science continues to exist as a living religious tradition with an organizational presence, a textual canon, and dispersed communities of practitioners and readers. Founded in the late nineteenth century by Mary Baker Eddy, who first published Science and Health with Key to the Scriptures in 1875 and formally organized the Church of Christ, Scientist in 1879, the movement developed international branches and a global footprint over the twentieth century. By the early 2000s and into the early 2020s, estimates of active membership and participation varied: some denominational reports and independent surveys suggested membership in the tens to low hundreds of thousands rather than the larger figures often cited in early twentieth‑century boosters’ accounts. Such demographic shifts reflect broader trends in American religion, including denominational realignment, partial secularization in some societies, and the diversification of spiritual options alongside the growth of evangelical and non‑Christian communities.
Geographically, Christian Science maintains a concentrated presence in the United States — especially in New England and in several metropolitan areas such as Boston and New York — with branches and societies across Europe, parts of Asia, Africa, Australia, and Latin America. Institutional centers remain important: The Mother Church (First Church of Christ, Scientist) and the Mother Church Extension in Boston continue to function as symbolic and administrative hubs, while the Christian Science Publishing Society historically situated on the Christian Science Plaza has been a focal point for the movement’s publishing and cultural outreach. The Christian Science Monitor, founded in 1908, long represented an outward‑facing engagement with public life; in the early twenty‑first century the Monitor reduced daily print publication and reoriented its operations to emphasize digital platforms and a weekly print edition, a shift that illustrates how the movement’s public institutions have adapted to evolving media and economic conditions.
Physical reading rooms and libraries remain a visible part of the tradition’s public presence. Reading Rooms, which offer access to Eddy’s writings, the Bible, the Monitor, and other periodicals, are maintained in many cities — for example in Boston, London, and New York — and function both as local contact points for the curious and as practical centers for members. The Mary Baker Eddy Library and its exhibits (including the Mapparium) attract visitors interested in the movement’s history, archival collections, and Eddy’s published works.
Textually, the movement centers on the Bible and Science and Health with Key to the Scriptures, together with the Church Manual (a text that outlines organizational and legal provisions for church government) and various writings and hymns associated with Mary Baker Eddy. The weekly Bible Lesson — commonly called the Lesson‑Ser mon — draws readings from the Bible and Science and Health and is used in Sunday services and study groups worldwide; the Christian Science Quarterly provides the lesson topics and citations for congregational study. The tradition teaches that these texts function as both theological authority and practical guidance for the life of the church, though adherents disagree about how literally or metaphorically certain passages should be read.
Internal diversity is a defining characteristic of the contemporary movement. Some congregations emphasize the healing tradition strongly and maintain active lists of named practitioners — individuals who offer prayerful support and are listed in national or regional directories — while other societies prioritize study, social outreach, and intellectual engagement with broader religious and scientific discourse. The process by which one becomes a listed Christian Science practitioner typically includes private instruction and class work with an authorized teacher, after which practitioners may register for inclusion in local or national directories that assist those seeking spiritual help. Attitudes toward conventional medicine vary considerably: while the tradition teaches that prayer is the primary means of healing, many adherents choose to combine prayer with medical care, and a substantial number make routine use of contemporary health services. This pragmatic variation reduces the likelihood of a uniform practice and reflects generational and cultural differences within the movement.
Contemporary debates within Christian Science often revolve around interpretation of Eddy’s writings, institutional governance, and the relationship to broader society. Questions about how to read Mary Baker Eddy’s language in light of contemporary scientific and medical knowledge surface in study groups, in articles in the Christian Science Journal and Sentinel, and in academic forums. Institutional discussions touch on recruiting and retaining younger members, balancing budgets for maintaining historic properties (including older church buildings and the Boston plaza), and adapting administrative structures to changing membership levels. Some members advocate for a hermeneutic that reads Eddy’s language metaphorically and seeks to harmonize spiritual practice with modern medicine; others maintain a more traditionalist approach emphasizing the priority of spiritual healing as presented in Eddy’s texts.
The movement’s relations with other Christian denominations and with secular institutions are varied. Ecumenical engagement has been limited historically, in part because of Christian Science’s distinctive metaphysical claims about matter and healing; nonetheless, there have been moments of cooperation, especially in civic and charitable endeavors, and individual Christian Scientists participate in broader interfaith dialogues and local service projects. In the public sphere, Christian Science has been drawn into legal and ethical debates about religious liberty and public health, particularly regarding medical care for children. Jurisprudence in the United States, the United Kingdom, Canada, Australia, and elsewhere over the past century and into the present has shaped the balance between parental religious freedom and child welfare laws, prompting legislative changes in some jurisdictions and high‑profile court cases in others. These legal encounters have contributed to ongoing public discussion about where religious practice intersects with state responsibilities for protecting minors.
Several contemporary movements and reforms have arisen from within and around Christian Science. Some organizations and study groups seek to preserve traditional practice closely, maintaining historical liturgical forms, disciplined study of Eddy’s works, and established healing procedures. Other networks aim to reframe Eddy’s work in contemporary theological terms or to emphasize ecumenical and interreligious dimensions. Outreach and education initiatives — including online courses, local “come and see” events in Reading Rooms, and digital resources — have become more prominent as the movement engages with potential adherents and the broader public. The history of internal disciplinary actions, such as the early‑twentieth‑century case involving Augusta Stetson, serves as a reminder that institutional cohesion has been an ongoing challenge as the movement matured, and debates over discipline and governance remain part of present organizational life.
Public perceptions of Christian Science continue to be mixed. The faith’s historic emphasis on spiritual healing appeals to some as a coherent model for integrating mind and body and as a form of lay spiritual authority historically shaped by a prominent female founder. Critics continue to express concerns about cases in which spiritual treatment was used to the exclusion of medical care for vulnerable people, and such incidents have shaped media coverage and policy responses. Scholarly treatments typically emphasize the movement’s significance in the American religious landscape, its early role in debates about medicine and gender, and its distinctive model of religious authority and textual centrality.
Education and training remain important in contemporary practice: branch churches run Sunday Schools and study groups, periodicals such as The Christian Science Journal and The Christian Science Sentinel publish articles that foster theological reflection and practical guidance, and directories and networks of practitioners and teachers facilitate pastoral work. Digital media, including webcasting of services, online lessons, and social‑media outreach, offer new platforms for dissemination and recruitment, while also raising questions about community, privacy, and the maintenance of tradition.
Finally, the living presence of Christian Science is visible in the ways adherents continue to practice, teach, and reinterpret Mary Baker Eddy’s legacy. The tradition is neither static nor monolithic: it comprises a field of communities negotiating continuity and change, authority and innovation. Whether in the quiet reading of a Lesson‑Ser mon on a Sunday morning, in a practitioner’s telephone or in‑person spiritual help, or in the continuing publication work of the Christian Science Monitor and other periodicals, Christian Science today remains a distinct voice in the ongoing conversation about faith, healing, and what it means to live spiritually in the modern world.
