From special events, lectures and more. Check out our events page for the latest from the MMGSI.
In conjunction with Borromeo Seminary and Saint Mary Seminary & Graduate School of Theology, MMGSI sponsors a series of public lectures each year.
Thanks to the generous support of the Lilly Endowment, MMGSI is able to sponsor paid summer internships at Catholic parishes around the diocese of Cleveland.
MMGSI offers laypeople the opportunity to take college-level courses on a range of topics, including Sacred Scripture, Trinity, Christology, and moral theology, without the financial or time commitments required for formal undergraduate study.
