The World Communion of Reformed Churches, created from the merger of the two largest networks of Protestant churches in the Reformed tradition, was celebrated June 18–26 in Grand Rapids, Michigan. The larger World Alliance of Reformed Churches (WARC) and the Reformed Ecumenical Council (REC) developed the plan between 2005 and 2007 to form the new body. The new ecumenical body has 227 member churches representing 80 million Christians in 108 countries. “The coming into being of the World Communion of Reformed Churches [is] a historic moment for the churches of the Reformed family and for the church of Christ everywhere,” said World Council of Churches general secretary Olav Fykse Tveit, who attended the uniting event. “The term ‘communion’ in the new organization’s name points to a new form of working relationship,” said Setri Nyomi, WARC general secretary.
