Acton Congregational Church (ACC), with about eight hundred members, is located in the historic district of Acton Center, west of Boston and bordering Concord, Massachusetts.

The church dates its beginning at 1832, although its history can be traced to the First Parish of Acton, which originated in 1735. In 1832 some 60 Trinitarian members withdrew from the First Parish to form the new Evangelical Church, which is our present church, and built its own meeting houses, one in 1833 and a larger one in 1846. The latter is the basic building in use today. The church celebrated its 150th anniversary in 1982; the Education wing was added in 2002; and the Rev. Dr. Richard Olmsted retired in 2005 after twenty-two years as our Senior Minister. The Reverend Andrew W. Armstrong was called as Senior Minister in September of 2007, and Mr. Holgie Choi was hired as Acting Youth Minister in October of 2007.

Congregationalism is that system of government of a religious denomination in which the members of the congregation govern the church; this system developed out of traditional Puritanism in the United States. The church members make decisions for the church, through boards, committees, special function groups, and congregational meetings and votes. In addition, our church is an active member of the United Church of Christ (UCC), one of more than 6,000 UCC congregations in the U.S. Each congregation practices its own form of organization, worship, education, and mission.
