At the invitation of Bishop John Carroll, Sulpicians from France open the first diocesan seminary in the United States, St. Mary’s Seminary in Baltimore, Maryland.

Nuns from the Congregation of the Sisters of Divine Providence of Kentucky begin their work of domestic care for the seminary and its residents. Now 70 seminarians reside in Caldwell Hall and the Paulists’ Apostolic Mission House.

The Basselin Foundation is established at Catholic University and the Sulpician Seminary, funded through a generous bequest from Theodore Basselin to provide for the education and training of exceptionally qualified philosophy students in college seminary studies, with a focus on public speaking and apologetics.

Seminarians are given responsibility for Sunday services at the National Shrine of the Immaculate Conception, including High Mass and Vespers. This continues for decades.

Sulpician Seminary becomes the university seminary of The Catholic University of America. That year, first-year seminarians take their classes at Catholic University. The next year, both first- and second-year seminarians receive their academic formation at Catholic University, followed then by first-, second-, and third-year men in 1939.

The Sedes Sapientiae statue is erected in the seminary courtyard as a gift from the alumni, marking the 25th anniversary of the seminary founding. It was later moved to the front walkway.

Theological College initiates pastoral formation as part of the overall program of preparation for priesthood.

During the 1980s, the seminary and University create the Pre-Theology Program (for seminarians who already have bachelor’s degrees) and a joint Sacred Theology Bachelors/ Masters of Divinity degree program.

Phase two of the renovation campaign is completed with new student and faculty rooms.

The seminary and University institute a five-year combined S.T.B and S.T.L. degree program.
