United Church of Christ

The United Church of Christ (UCC) is a mainline Protestant Christian denomination primarily in the Reformed tradition, in "historical continuation of the Congregational churches founded under the influence of New England Puritanism." The Evangelical and Reformed Church and the Congregational Christian Churches united in 1957 to form the UCC. These two denominations, which were themselves the result of earlier unions, had their roots in Congregational, Evangelical, and Reformed denominations. The UCC's 5,287 congregations claim 1,080,198 members, primarily in the United States.

The UCC maintains full communion with other mainline Protestant denominations. Many of its congregations choose to practice open communion. The denomination places high emphasis on participation in worldwide interfaith and ecumenical efforts. The national settings of the UCC have historically favored liberal views on social issues, such as civil rights, gay rights, women's rights and abortion rights. However, United Church of Christ congregations are independent in matters of doctrine and ministry and may not necessarily support the national body's theological or moral stances. It is self-described as "an extremely pluralistic and diverse denomination".
