Cornerstone Bible Church is the oldest continuing congregation in the City of Xenia, tracing its roots back to settlers who migrated to this area from Pennsylvania. The original organization, dating from March 1833, included several churches in this area. The First German Reformed Church of Xenia, was independently adopted on February 17, 1836, then in 1869 the denomination dropped the word "German" from its title. Later, in 1934, the denomination merged with the Evangelical Synod of North America to become the Evangelical and Reformed Church. However, in 1957, the denomination began the process of merging with the Congregational Christian Church to form the United Church of Christ. Our church understood the need to withdraw from the new denomination that was forming to preserve our spiritual heritage; therefore, the congregation voted on September 8, 1957, to retain our name, First Reformed Church, and to eliminate their denominational affiliations.

In May 2005, Bill Vine was called to be our Pastor. On December 12, 2004, the members unanimously approved a new name for the church - Cornerstone Bible Church.

From its beginning, the church has met to worship the Lord and to study His Word, the Holy Bible, which has remained the sole and final authority. We desire, as did the Reformers, to embrace the truth of God's Word, and to see that truth embodied in doctrine, worship, and life. Like them, we affirm salvation by grace through faith in Jesus Christ alone. Unlike the early Reformers, however, we now encourage believer's baptism by immersion.

We are thankful for our heritage, and we are confident that the Lord will continue to bless us as a congregation until He comes for His church.

Our present location, on the corner of North Detroit and West Church Streets, was built in 1909-10, and was dedicated on October 2, 1910.
