During the 1840s, Rev. Paul Couch, minister at the First Parish Congregational Church in North Bridgewater, began to liberalize some of the more traditional teachings and traditions of the church. In response, some members of the church called for Rev. Couch to resign. Over the course of two years between 1948 and 1950, members of the liberal and orthodox wings of the church debated over Rev. Couche’s position. Ultimately Rev. Couch did not resign and his continued service was maintained by the church. In response, approximately 70 names of persons interested in forming a new church were collected on February 12, 1850. An ecclesiastical council was called for March 6 and from that meeting the Porter Evangelical Church was formally gathered. John F. Norton was installed as the first minister of the church and stayed for a year. In 1852, Charles L. Mills was installed as pastor.

The newly formed congregation initially met at Tyler Cobb’s Hall; their first meeting was held on March 10, 1850. In order to purchase land for a church, the Porter Society was formed on March 20, 1850. In 1851 the society purchased and renovated an old building on Main Street just north of the First Parish Congregational Church. In 1869 the top of the church spire was destroyed during a wind storm. The steeple was repaired in 1883 while the church itself underwent a major renovation and expansion project.

The Church Work Committee was formed in 1885. Its initial function was to assist the pastor and provide help to the Porter Church’s parishioners. However that mission quickly expanded to include the management of Brockton area missions to provide sanctuary spaces for poor and disenfranchised citizens in the north-east of Brockton. Out of that mission both the Wendell Avenue Church, which began as the Wendell Avenue Chapel, and the Waldo Congregational Church, which began as the Montello Mission, were established in the mid-1890s.

At some point in the mid-1910s, the church name changed to The Porter Congregational Church. The church building was again renovated in 1925 as part of planned anniversary activities. The renovation also included the construction of a new steeple. The renovations also included the construction of a multi-purpose recreational building behind the church. There were further renovations completed in 1950 as part of the centennial celebrations. In 1980, the Porter Congregational Church merged with the First Parish Congregational Church, South Congregational Church, and Waldo Congregational Church to form the Christ Congregational Church in Brockton. The Porter Congregational Church building is now the headquarters for the Keys of The Kingdom Tabernacle of Prayer For All People, International.
