Together, they encompass
100,000 local congregations and
45 million adherents.
The
NCC has long been a leading force in the Christian ecumenical movement in the United States.
National Council of Churches was organized in
1950 as a merger of the
Federal Council of Churches, formed in
1908, and the
International Council of Religious Education, formed in
1905, with origins in the
1830's.
The Council's sister organization,
Church World Service, is a humanitarian and relief arm of the NCC's member communions which has work in more than 80 nations.
The Council is related fraternally to hundreds of local and state councils of churches and interfaith organizations, and to the World Council of Churches. Even though these councils may include many of the same member churches, they have no fiscal or administrative connections to each other.
