St. John's Union Church has a rich history of two blended congregations with great beginnings over 150 years ago and continuing to thrive today, growing and keeping pace with today's changing society. Nestled in the hamlet of Farmer's Mills on the crossroads between Routes 45 and 192 in a quiet country setting, you will find a white church known as St. John's. Step inside and you will be most welcome and feel at home in this Christ centered congregation. It won't be long until you understand why St. John's is one of the few successful union congregations . Here we gather, worship, and enjoy the fellowship of one another as brothers and sisters in Christ.

One of the many advantages to a union congregation is that the congregation shares in the uniqueness of both the United Church of Christ and the Lutheran Worship Services, celebrating our differences yet embracing our same faith and love of Jesus Christ. At St. John's we seek to share the love of Christ with all; our mission is to serve Christ in our community. The congregation, though made up of Lutheran and United Church of Christ members work together in love and harmony, serving the same Lord and Savior and letting His Light shine in the world.

In addition to the unity of two congregations within our church, we have three sister churches, within our two Parishes. Our Lutheran sister in the Spring Mills Lutheran Parish is New Hope Lutheran Church of Spring Mills. Our U.C.C. sister churches are Grace UCC Church in Spring Mills and Emmanuel Church in Tusseyville, together with St. Johns these three churches make up the Tri-Penn UCC Charge.
