In 1843, 123 members of the First Congregational Church of Guilford who were strongly anti-slavery decided to form their own church, the Abolition Church, later renamed the Third Congregational Church of Guilford. These members had been refused permission by First Church to hold meetings of the local Anti-Slavery Society. They were also supporters of Rev. Aaron Dutton, First Church’s minister from 1806 to 1842, who had resigned due to dissensions within the congregation over his abolitionist stance. As related in The History of Guilford, Connecticut (1877), by Ralph D. Smith:
The present house of worship was built in 1844, and dedicated to the service of God, January 1, 1845. It was remodeled in 1862, and supplied with a suitable organ in 1873.
A chapel at the rear was added in 1879. By 1919 church membership had dwindled. The congregation of Third Church rejoined First Church and sold the building (49 Park Street) to Christ Church for use as a parish house. The building‘s steeple was removed in the 1920s because it had begun to lean. For several years, the former church was used as a movie theater, a kindergarten and a dancing school. In 1933 the building was sold again and renamed the Chapel Playhouse. It was converted for use by a summer stock theater group, the New York-Guilford players, and for the Guilford Town Players. The Christian Science Society bought the building in 1951 and restored it, changing their name in 1955 to the First Church of Christ, Scientist.
