The Berkley, Mass. Congregational Church records document the early history, administration, and life of the church and its members, as well as a major split that occured within the community. The collection includes financial records, church and parish records, including meeting minutes, committee reports, records of votes, sermons, and certificates of membership, disciplinary cases, and vital statistics, such as marriage and baptismal records. Also present in the collection are record books which relate to the Trinitarian Congregational Society, which split from the Congregational Society in 1848, and include narratives for why they split from the church as well as foundational documents for their new church society.
