On November 21st, 1966, the First Brethren Church of Compton and the First Brethren Church of Bellflower consolidated to form the Bellflower Brethren Church. Both of the "parent" churches were founded in the 1930's by Grace Brethren families who lived in the Long Beach area. The church in Bellflower originally built a "basement church" on Park St. after which the Brethren Home Missions Council helped them purchase land and construct a small white church on the corner of Flower St. and Clark Avenue. The church was led at various times by George Richardson, Pastor Hall, Dr. Harry Sturz, Dr. Curtis Mitchell, and Dr. Al Flory. At the time of the merger, Ray Thompson had been the pastor for at least 5 years.

The Compton church (located at the corner of Rose and Rosecrans) also had had many different pastors (Forest Lance, Ralph Colburn, Norman Nelson, Dennis Holiday, Bill Smith) and struggled with the changing ethnicity of its community. Many of the church's members moved away from the community. In the early '60's Pastor Edwin Cashman was called to serve as the pastor of the Compton church. In 1966, Pastor Cashman and Pastor Ray ("Bud") Thompson agreed to co-pastor their new church, Bellflower Brethren, for the period of one year. Within the year, however, Rev. Thompson was called to minister elsewhere and the church called Ed Cashman to serve as its pastor.

The Compton Church's property was sold after the merger of the two churches and the new church attempted to find a new location. Eventually, the church decided to build new facilities on their existing property in Bellflower. Over a period of years an educational facility, church office, and worship center were constructed. In later years, two more parcels of land were purchased to provide more parking and a youth center.

Rev. Cashman led the church for the next 26 years and then asked to switch roles with his associate pastor, Tom Hocking, in October of 1992. Pastor Ed continued to serve actively as the minister of pastoral care until he was suddenly promoted to the Lord's presence in January of 1997.

Pastor Hocking, who joined the church as a Biola student in 1981, was invited to join the pastoral staff in June of 1985 after he completed his M.Div. Over the last 15 years the church has become more intentional about impacting its increasingly diverse community. The church is now bilingual and bicultural but continues to be be mission-focused with a family-centered, relationship-oriented atmosphere in which the virtues of humility, grace, and forgiveness are highlighted. The church's mission statement declares: "We are here to proclaim Christ to the world until He comes, through our worship and our relationships."
