Lancaster Theological Seminary

Lancaster Theological Seminary, a graduate school of theology affiliated with the United Church of Christ, is a vibrant, diverse learning community known for academic excellence, celebration of differences across Christian traditions, and creative engagement on issues of importance to our world. Founded in 1825, the campus is located in Lancaster, Pennsylvania and is known for being the birthplace of Mercersburg theology.

Evangelical & Reformed Historical Society

The Evangelical and Reformed Historical Society is located on the second floor of the Schaff Library building at Lancaster Theological Seminary. Whether you are researching family members who participated in our constituent churches, planning a church anniversary service, or looking for a home for your church’s records, we may be able to assist. Founded in 1863 as the Historical Society of the German Reformed Church, the Evangelical and Reformed Historical Society was formed in 1934 when the Reformed Church in the United States merged with the Evangelical Synod of North America.

Mercersburg Society

The Mercersburg Society was founded in 1983 to uphold the concept of the Church as the Body of Christ, Evangelical, Reformed, Catholic, Apostolic, organic, developmental, and connectional. The Society works to provide opportunities for fellowship and study for persons interested in Mercersburg Theology, to sponsor convocations, to engage in publication of articles and books, and to stimulate research and correspondence among scholars on topics of theology, liturgy, the sacraments, and ecumenism.
