National Council of Churches
The National Council of the Churches of Christ in the USA, usually identified as the National Council of Churches (NCC), is an ecumenical partnership of 38 Christian faith groups in the United States. Its member denominations, churches, conventions, and archdioceses include Mainline Protestant, Orthodox, African American, Evangelical, and historic peace churches. Together, they encompass more than 100,000 local congregations and 40 million adherents. It began as the Federal Council of Churches in 1908, and expanded through merger with several other ecumenical organizations to become the National Council of Churches in 1950.
The NCC's influence reached its peak in the 1950s, largely because of its commitment to ecumenism, and to the popularity of a wide variety of collaborative programs and ministries undertaken by its member churches, including the humanitarian movement, Church World Service.
The Council's 38 member denominations, churches, conventions, and archdioceses include Mainline Protestant, Orthodox, African American, Evangelical, Josephite, and historic peace churches. Individual adherents of more than 50 Christian faith groups actively participate in NCC study groups, commissions and ministries. Some of these participants belong to Christian faith groups, including the Roman Catholics, fundamentalists, Southern Baptists, and Missouri Synod Lutherans, that are not officially a part of the Council's membership.
All NCC member organizations subscribe to the NCC's statement of faith, which forms the preamble to the NCC's charter: "The National Council of Churches is a community of Christian communions, which, in response to the gospel as revealed in the Scriptures, confess Jesus Christ, the incarnate Word of God, as Savior and Lord. These communions covenant with one another to manifest ever more fully the unity of the Church. Relying upon the transforming power of the Holy Spirit, the communions come together as the Council in common mission, serving in all creation to the glory of God." 
Social and political advocacy
According to Gill (2011), the NCC's position against the Vietnam War became increasingly strident in the 1960s and 1970s, and alienated the laity. As in the Mainline churches, the senior officials and the laity had diverging positions on public policy. At one point conservative media falsely reported NCC had channeled money to Communist groups in Vietnam and left-wing groups in Central America, provoking an outcry. Even the NCC's defenders admitted it had been "opaque" and "tone-deaf to their constituents."
Although often accused of being a left-wing organization, the NCC never attracted support from the New Left. The result of being caught in the national polarization between left and right in a variety of controversies has been a long-lasting challenge to its influence.
The member churches have engaged on issues of public policy and moral values, including the adoption of the "Social Creed of the Churches" in 1908, a document addressing the moral and ethical issues facing society, updated by the NCC General Assembly in 2007.
Since the late 1960s the NCC has taken positions sympathetic towards Palestinian land rights.
NCC partners with dozens of other faith-based groups, such as Bread for the World, Habitat for Humanity, and Children's Defense Fund, to press for broad policy initiatives that address poverty issues. The Council helped launch the Let Justice Roll grassroots anti-poverty campaign that has been successful in raising the minimum wage in more than 20 states since 2005.
In July 2005, the Antiochian Orthodox Church suspended its participation in the NCC because, according to an assistant to the denomination's senior cleric, "the NCC...seems to have taken a turn toward political positioning." 
Publishing and research
The NCC fostered the multi-denominational research effort that produced the Revised Standard Version and the New Revised Standard Version of the Bible, and holds the copyright to both translations.
The NCC sponsors the research program on which the Uniform Sunday School Lesson Series is based. The series began in 1872 under the auspices of the National Sunday School Convention.
The NCC also published until 2012 the annual Yearbook of American and Canadian Churches, since 1916 a widely used reference work on trends, statistics and programmatic information on religious organizations in North America. Future editions of the Yearbook will be published by the Association of Statisticians of American Religious Bodies (ASARB).
Theological and ecumenical dialogue
The NCC Faith and Order Commission is an ongoing, scholarly, ecumenical dialogue among North American Christian theologians and church historians, including Evangelical, Pentecostal, Roman Catholic, Orthodox, mainline Protestant, and African-American scholars. In 2007, the Commission celebrated its fiftieth anniversary.
The NCC is a founding member of the Interfaith Broadcasting Commission, a partnership established in 1980 to provide religious television programming for the local affiliates of ABC, NBC and CBS. The current IBC members include a variety of Jewish, Muslim, Protestant and Catholic organizations.
The Council was the original anchor tenant in the 19-story Interchurch Center built in 1952 adjacent to Columbia University, Union Theological Seminary and The Riverside Church in New York City. It vacated these premises in 2013 when it consolidated its offices in the building long used by its public-policy staff at 110 Maryland Avenue, N.E., on Capitol Hill in Washington DC.
