Harmony Creek Church is affiliated with the United Church of Christ and Alliance of Baptists. Our mission is to be a community of progressive Christians sharing our journeys, doing ministry, seeking justice, and living God’s love.

We have a clear vision: we seek to embody the ministry, message, and hope of Jesus of Nazareth, serving as a vital and leading voice for progressive Christianity in the Miami Valley.

Harmony Creek Church is a new church, but has long and historic roots in the Miami Valley dating back to 1833. Harmony Creek Church began worshipping together on Christmas Eve of 2012 and is the merger of two congregations: Oak Creek United Church of Christ and Cross Creek Community Church, United Church of Christ.

Oak Creek UCC was formed in 1963, the result of a merger between Central United Church of Christ, which was located on Ludlow Street in downtown Dayton, and the Fair Lea United Church of Christ, which was located in an old mansion at 456 Whipp Road in Centerville. Central United Church of Christ (1922 – 1964), was formerly called Central Evangelical and Reformed Church, and before that, Central Reformed Church. Central Reformed Church was formed as the merger of the First Reformed Church (1833 – 1922), the Trinity Reformed Church (1886 – 1922) and the Fourth Reformed Church (1892 – 1928). Fair Lea United Church of Christ (1859 – 1963) was formerly known as Fair Lea Evangelical and Reform Church, and before that as Second Reformed Church, which was located at Cass and Clay Streets in the Oregon District in downtown Dayton.

In 1960, the Central United Church of Christ sold their building to the Rike-Kumler Company. The Central UCC building was torn down to make way for a new parking garage. After the church sold, two congregations were formed and two buildings were built. Half of the Central UCC went north to form the Mt. Olive United Church of Christ, located at 5501 Olive Road, just off of SR 49 near the old Salem Mall. The other half of the old Central UCC went south, merging with the Fair Lea UCC to form the Oak Creek United Church of Christ. The Oak Creek UCC building was completed in 1964 at 5280 Bigger Road in Kettering.

Cross Creek Community Church, United Church of Christ, was formed in 1997 as a new church of the United Church of Christ and the Alliance of Baptists. Cross Creek Community Church was founded to be contemporary, progressive and an ‘open and affirming’ congregation, welcoming and reaching out to the gay, lesbian, bisexual and transgender community. The church was started in a store front at 5800 Bigger Road and later purchased a 5600 sq. ft. building at 667 Miamisburg-Centerville Road in Washington Township in 2001. Cross Creek Community Church quickly out grew that facility. However, expansion of that building was going to require an investment of 4 to 5 million dollars.

After becoming aware of Oak Creek UCC’s declining membership and the struggles of that decline, Cross Creek Community Church UCC approached Oak Creek UCC to see if they might be interested in exploring a possible merger, which they enthusiastically embraced. The merger of our two congregations was and has been overwhelmingly embraced by both congregations. Oak Creek UCC gained an influx of parishioners as well as pastoral and programmatic staff for children and youth from the merger. Cross Creek UCC gained a 32,000 square foot building by which to grow and expand and also eliminated $500,000 in mortgage debt. Both congregations have been strengthened by this merger. Already, Harmony Creek Church is seeing new energy and many new visitors and members.
