The
mainline Protestant churches (also called
mainstream American Protestant and
oldline Protestant) are a group of
Protestant churches in the United States that contrast in history and practice with
evangelical,
fundamentalist, and
charismatic Protestant denominations. Mainline Protestants were a majority of all Christians in the United States until the mid-20th century, but now constitute a minority among Protestants. Mainline churches include the
United Methodist Church (UMC), the
Evangelical Lutheran Church in America (ELCA), the
Presbyterian Church (U.S.A.) (PCUSA), the
Episcopal Church, the
American Baptist Churches, the
United Church of Christ (Congregationalist), the
Disciples of Christ, and the
Reformed Church in America, among others.
