St. Mary's Seminary & University

Master’s Programs

St. Mary’s Ecumenical Institute offers accredited graduate theological programs for two master’s degrees, several graduate certificates, and introductory explorations. St. Mary’s Ecumenical Institute also offers master’s level coursework leading to a Master of Divinity through Lancaster Theological Seminary.


St. Mary’s Ecumenical Institute offers the Master of Arts in Theology, a general theological studies degree, and the Master of Arts in Christian Ministries, a ministerial leadership degree. Each master’s degree requires 48 credits (16 three-credit courses) including a culminating experience. Each master’s level program is designed primarily for part-time study over several years but is the equivalent of a two-year full-time program.

Master of Divinity Partnership

St. Mary’s Ecumenical Institute has partnered with Lancaster Theological Seminary to create a path to the Master of Divinity.  Students will take the first half of their MDiv coursework from the Ecumenical Institute, then complete the degree in Lancaster’s accessible weekend program.


St. Mary’s Ecumenical Institute offers several master’s level certificates designed primarily to serve the needs of laypersons interested in ministry in churches, schools, hospitals, and religious or community organizations. The post-master’s Certificate of Advanced Studies is a 30-credit degree program designed for individuals who possess a master’s degree in theology, ministry, divinity, or a related field. Candidates may pursue a general program or concentrate in biblical studies, history, moral theology (theological ethics), practical theology, spirituality, or systematic theology.
