The American Congregational story has its origins in 16th century England, and is still being written today, 5 centuries later! The Congregational Church was the church of the Pilgrims and of the Mass. Bay Colony Puritans, who were interested in establishing a Reformed tradition church state in the new world. After several generations, some churches changed to become Unitarian or Universalist churches. In 1931, the remaining Congregational Churches merged with the Christian Church movement to become Congregational-Christian churches. Then, in 1957, the majority of these churches dropped the Congregational-Christian name in another merger with the Evangelical & Reformed Church. A remaining minority formed a National Association of Congregational Christian Churches (NACCC), and MACCC is Massachusetts’ association of continuing Congregational Christian Churches.  The association itself is to allow local congregations to consult and advise together as churches upon matters of common concern to them, both temporal and spiritual, without infringing on their powers of self-government.
