The Reformed Ecumenical Council (REC) was an international organization of Calvinist churches.
It had 39 member denominations from 25 countries in its membership, and those churches have about 12 million people together.
It was founded August 14, 1946 in Grand Rapids, Michigan as the Reformed Ecumenical Synod.
The seat of the Reformed Ecumenical Council was Grand Rapids, Michigan, United States.
After a two-day meeting ending on 1 February 2006, Douwe Visser, president of the REC and Clifton Kirkpatrick, president of the World Alliance of Reformed Churches, said in a joint letter to their constituencies, "We rejoice in the work of the Holy Spirit which we believe has led us to recommend that the time has come to bring together the work of the World Alliance of Reformed Churches and the Reformed Ecumenical Council into one body that will strengthen the unity and witness of Calvinist Christians."
