secularismnoun
SEK-yoo-lur-iz-um
The principle that religion should be kept separate from government, public education, and civic life. Secularism does not require that individuals be non-religious — it concerns the institutional relationship between religious authority and the state.
"French secularism — laïcité — is unusually strict: it prohibits religious symbols in public schools and government buildings, regardless of the wearer's faith."
secularizationnoun
sek-yoo-lur-ih-ZAY-shun
The historical process by which religion loses social and cultural significance — declining in institutional power, public authority, and personal practice. The secularization thesis predicted religion would fade as societies modernized; recent data complicates that picture.
"Secularization has proceeded rapidly in Western Europe, where church attendance has collapsed within a generation, while religion remains robust in the United States and the Global South."
pluralismnoun
PLOOR-ul-iz-um
The condition of society in which multiple religious, cultural, and worldview traditions coexist. Religious pluralism also refers to the theological view that multiple religions offer valid paths to ultimate truth or salvation — a position held by some but contested by many traditions.
"Living in a pluralist society requires learning to disagree respectfully with people whose deepest beliefs differ fundamentally from your own."
interfaith dialognoun phrase
IN-ter-fayth DY-uh-log
Constructive conversation between people of different religious traditions, aimed at mutual understanding, cooperation, and the peaceful resolution of differences. Interfaith dialog does not require participants to abandon their own convictions.
"The interfaith dialog brought together Jewish, Muslim, and Christian clergy to find common ground on community service — without requiring any of them to compromise their theology."
spiritual but not religiousadjective phrase
SPIR-ih-choo-ul but not rih-LIJ-us
A self-description used by people who hold spiritual beliefs or practices — a sense of transcendence, meaning, or connection — but who do not identify with any organized religious tradition. This demographic has grown significantly in recent decades.
"She described herself as spiritual but not religious — she meditated daily and believed in something greater than herself, but felt no affinity with any church or creed."
nonesnoun (plural)
nunz
People who, when asked their religious affiliation, respond "none" — including atheists, agnostics, and those who are simply religiously unaffiliated. The "nones" are the fastest-growing religious demographic in the United States and much of Western Europe.
"The rise of the nones does not necessarily mean a rise in atheism — many unaffiliated people still hold private spiritual beliefs."
de-churchingnoun
dee-CHURCH-ing
The process by which individuals who previously attended religious services stop doing so, often gradually. De-churching is distinct from deconversion: a person may stop attending church while retaining personal faith.
"Research suggests that de-churching often begins not with theological doubt but with practical drift — a missed Sunday that becomes a habit."
fundamentalismnoun
fun-duh-MEN-tul-iz-um
A movement within a religion characterized by strict adherence to a set of basic principles — typically a literal interpretation of sacred texts — and opposition to modernity, secularism, and liberal theology. The term originated in early twentieth-century American Protestantism.
"Religious fundamentalism tends to intensify in response to perceived threats from secular culture — it is often as much a social reaction as a theological position."
syncretismnoun
SIN-kruh-tiz-um
The combining of different religious beliefs and practices into a new unified system. Syncretism is common at the boundaries where traditions meet; it is viewed positively as creative blending by some and as distortion or dilution by others.
"Brazilian Candomblé is a striking example of syncretism — a religion that fused West African Yoruba beliefs with elements of Catholicism during the colonial period."
lived religionnoun phrase
livd rih-LIJ-un
The study of how ordinary people actually practice and experience religion in everyday life, as distinct from official doctrine or institutional religion. Lived religion attends to personal prayer, ritual, superstition, and the mixing of traditions.
"Lived religion research found that many people combine official Catholic practice with folk healing and private rituals that the Church neither endorses nor knows about."
civil religionnoun phrase
SIV-ul rih-LIJ-un
The set of quasi-religious beliefs, symbols, and rituals through which a nation sacralizes its own history and identity — as in American references to "one nation under God," patriotic ceremonies, and the veneration of founding figures. The term was developed by Robert Bellah.
"Memorial Day, Thanksgiving, and the Pledge of Allegiance are all elements of American civil religion — rituals that give national life a sacred quality."
disenchantmentnoun
dis-en-CHANT-ment
Max Weber's term for the process by which modernity strips the world of mystery, magic, and sacred meaning — replacing an enchanted cosmos with a rationally calculable one. Disenchantment is considered a defining feature of secular modernity.
"Weber's disenchantment describes a world in which lightning is no longer God's anger but a discharge of static electricity — explicable, predictable, and devoid of meaning."
re-enchantmentnoun
ree-en-CHANT-ment
The cultural and spiritual search for meaning, mystery, and the sacred in a disenchanted modern world. Re-enchantment can take religious, spiritual, aesthetic, or ecological forms — a hunger for transcendence that secularism has not eliminated.
"The popularity of wellness culture, astrology, and new spiritualities reflects a re-enchantment — a desire for mystery and meaning that organized religion no longer provides for many people."
religious literacynoun phrase
rih-LIJ-us LIT-er-uh-see
Basic knowledge of the world's major religious traditions, their texts, histories, and practices — sufficient to understand their role in current events, art, and culture. Religious literacy is considered essential for civic life in pluralist societies.
"A journalist without religious literacy will misunderstand the motivations of billions of people whose actions are shaped by faith."
deconversionnoun
dee-kun-VUR-zhun
The process by which a person abandons a religious faith they previously held, often after a period of doubt and intellectual struggle. Deconversion can be as emotionally significant as conversion, involving a loss of community, identity, and meaning.
"Her deconversion was not a single moment but a slow unraveling — years of questions the church couldn't answer, followed by a quiet decision she had stopped believing."
conversionnoun
kun-VUR-zhun
The adoption of a new religious faith, often involving a significant transformation of identity, values, and community. Conversion may be gradual or sudden; it can be driven by intellectual conviction, emotional experience, social pressure, or personal crisis.
"William James described conversion as the process by which a self hitherto divided becomes unified around a new center of personal energy."
religious identitynoun phrase
rih-LIJ-us eye-DEN-tih-tee
The aspect of a person's self-understanding that is shaped by their religious affiliation, beliefs, and practices. Religious identity can be deeply held or largely nominal — people may identify with a tradition culturally without embracing its theology.
"Many people maintain a strong religious identity — attending holidays, marking rites of passage — without attending services or holding orthodox beliefs."
digital religionnoun phrase
DIJ-ih-tul rih-LIJ-un
The study of how religious practice, community, and identity are shaped by and expressed through digital media — including online worship, social media faith communities, apps for prayer and meditation, and religious radicalization online.
"Digital religion exploded during the pandemic, as millions attended virtual services — raising questions about whether online community can truly replace physical presence."
religious nationalismnoun phrase
rih-LIJ-us NASH-un-ul-iz-um
A political ideology that combines national identity with religious identity — defining the nation as essentially belonging to a particular religious community and its values. Religious nationalism can be a powerful force for mobilization and, at its extreme, exclusion or violence.
"Religious nationalism frames political opponents not just as wrong but as enemies of God — raising the stakes of ordinary political disputes to cosmic levels."
ecumenismnoun
ih-KYOO-muh-niz-um
The movement among different Christian denominations to promote unity and cooperation. More broadly, ecumenism refers to efforts toward mutual understanding and common action among different religious traditions. It gained momentum in the twentieth century.
"Ecumenism brought Catholics and Protestants together in joint social justice campaigns, even as they maintained theological differences on sacraments and authority."
mysticismnoun
MIS-tih-siz-um
The pursuit of a direct, personal experience of union with God or ultimate reality, typically through contemplative practices such as prayer, meditation, or asceticism. Mystical experience is reported across virtually all religious traditions and remains a significant data point in the study of religion.
"Mysticism cuts across doctrinal boundaries — the descriptions of union with the divine from Sufi poets, Christian contemplatives, and Hindu sages are strikingly similar."
theodiversitynoun
thee-oh-dih-VUR-sih-tee
The range and variety of religious and spiritual traditions present in a given society. Like biodiversity, theodiversity is valued by pluralists as a sign of cultural richness and a resource for human flourishing — each tradition offering distinct insights.
"The city's theodiversity was visible on a single street: a mosque, a synagogue, a Hindu temple, and an evangelical church, each drawing its own community."
nominal religionnoun phrase
NOM-ih-nul rih-LIJ-un
Religious affiliation in name only — identifying with a tradition through cultural habit or family loyalty without active practice or personal belief. Nominal religion is widespread in post-Christian Europe, where many people describe themselves as Christian but rarely engage with the faith.
"He was nominally Catholic — baptized, married in the Church, and buried with its rites — but had not believed in God since his twenties."
sacred canopynoun phrase
SAY-kred KAN-uh-pee
Peter Berger's metaphor for the shared symbolic universe — the plausibility structure — that religion provides, sheltering human life from meaninglessness and chaos. The modern collapse of the sacred canopy, Berger argued, creates a crisis of meaning that secularism struggles to fill.
"When the sacred canopy tears, people are left without a shared framework for meaning — which may explain both the growth of the nones and the intensity of new secular ideologies."
