St. Peter's Evangelical Church was founded in 1861 on a tract of land purchased for $5.00 from the Leistner family.  The early informal and formal meetings of the congregation, as well as the first worship services, were held in a small log building located south of the cemetery.  A frame church was built sometime during the years of 1862 and 1863.  The congregation continued to grow and construction on a new, larger
church began in 1901.

All early members of the church were German immigrants and only German was spoken during worship and other church activities.  In 1921, many of the younger members of the church no longer spoke German and it was decided that on the last Sunday of each month, worship would be conducted in English.  This began a slow, roughly 20 year transition to English. 

In 1941, the Evangelical denomination merged with the Reformed Church and the church became St. Peter's Evangelical and Reformed Church. 

The United Church of Christ was formed when the  Evangelical and Reformed Church merged with the Congregational Christian Church in 1956.  The church then became St. Peter's United Church of Christ.  St. Peter's has from her founding been yoked with her sister congregation, Trinity United Church of Christ in Fulda.   

St. Peter's has long been engaged in God's work in local, national, and international ministries, including Cincinnati, Honduras, Nicaragua, Niger, and Sri Lanka.
