The Mainline Protestant churches are a group of Protestant churches in the United States that contrast in history and practice with evangelical, fundamentalist, and charismatic Protestant denominations, although some mainline churches include evangelicals and charismatics. 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, the Evangelical Lutheran Church in America, the Presbyterian Church, the Episcopal Church, the American Baptist Churches, the United Church of Christ, the Disciples of Christ, Reformed Church in America, and Hicksite Quakers, among others. Mainline churches share a common approach to social issues that often leads to collaboration in organizations such as the National Council of Churches. Because of their involvement with the ecumenical movement, mainline churches are sometimes given the alternative label of ecumenical Protestantism. These churches played a leading role in the Social Gospel movement and were active in social causes such as civil rights and equality for women.
