About the Ecumenical Institute (EI)


St. Mary’s Ecumenical Institute (EI) was founded in 1968 by St. Mary’s Seminary & University, America’s oldest Roman Catholic seminary, in cooperation with ecumenical leaders. St. Mary’s is accredited by the Association of Theological Schools and by the Middle States Association of Colleges and Schools. The Ecumenical Institute invites people of all denominations into theological study that pursues excellence and promotes ecumenical understanding and respect.

An Invitation to All

Students, Programs, and Faculty

Our students are mostly working adults who are part-time learners following the ancient motto of “faith seeking understanding.” They pursue individual courses, one of several certificates, master’s degrees, a Certificate of Advanced Studies, or a Doctor of Ministry degree. Classes are held mostly on weekday evenings and Saturdays, and all of our programs are available wherever you are – on campus in Baltimore, and on-line. There are three terms per year: fall, winter, and summer. Tuition is very reasonable—the lowest in the region for accredited, graduate, theological education.

Our student body of women and men is both interdenominational and interracial, as is our excellent faculty. All of St. Mary’s Ecumenical Institute’s professors have earned doctorates, and a significant number are well-known published scholars. 

We hope you find our site interesting and informative, and we look forward to hearing from you!
