Nondenominational Christianity names a large and growing family of self-governing Christian congregations that deliberately hold no affiliation with any denomination. Pew Research Center's Religious Landscape Study classifies nondenominational Protestants as their own family within American Christianity, distinct from Baptist, Methodist, Lutheran and the other named traditions the study tracks. The distinguishing fact about the family is not a shared belief but a shared refusal: each member congregation has chosen not to answer to a denominational headquarters, confession or governing body above the local church.
The category is not new, but it has grown sharply. The National Congregations Study, the ongoing national survey directed by Mark Chaves at Duke University since 1998, documents a rising share of American congregations identifying as nondenominational across the study's four survey waves, a trend Chaves and Shawna Anderson report directly from the study's third wave. Scholars writing on what is sometimes called post-denominational Christianity trace the pattern to the independent Bible church and megachurch movements that grew rapidly in the United States from the mid twentieth century onward, though unaffiliated congregations following the same pattern exist elsewhere.
Because the category is defined by what its members refuse rather than by what they affirm, no single confession, polity detail or liturgical practice can honestly be attributed to it as a whole. A reader looking for what nondenominational churches believe should expect the answer that follows in the next entry: not a creed, but a range.
