Ecumenical councils and agencies

The United Church of Christ is a founding member of the National Council of Churches, the World Council of Churches and many other ecumenical agencies and projects. The NCC and WCC began to take shape in the late 19th-century in response to the worldwide ecumenical movement.

The UCC is also a member of the World Alliance of Reformed Churches—the worldwide communion of churches in the Reformed, Presbyterian and Congregationalist traditions.
