Aquinas Institute Snapshot


We are a center for institutional studies for the Order of Preachers. At the same time, and as a central component to the formation of our Dominicans in formation, we are committed to educating the future lay leaders of our church as one mission. 


Aquinas Institute offers 8 degree programs at the graduate level, the only Doctor of Ministry in Preaching at Catholic school, as well as three graduate certificate programs. 


As a Catholic graduate school of theology, Aquinas Institute carries forward an 800 year tradition of the Order of Preachers. 


Fully Funded Aquinas Scholarships available for full-time students in our M.A. Theology, M.A. Pastoral Studies, and Master of Divinity Programs.


Situated adjacent to the large and beautiful campus of Saint Louis University, our students have access to all the academic resources of a major Catholic university while studying with the Dominicans in their House of Studies. 


For over 95 years Aquinas Institute has been educating Church leaders in the tradition of St Thomas Aquinas.

Not just a school of Theology, but a truly dynamic faith community.
