The Thomistic Institute

Catholic Truth in a Contemporary World


The Thomistic Institute exists to promote Catholic truth in our contemporary world by strengthening the intellectual formation of Christians at universities, in the Church, and in the wider public square. The thought of St. Thomas Aquinas, the Universal Doctor of the Church, is our touchstone.  

The TI is an academic institute of the Pontifical Faculty of the Immaculate Conception at the Dominican House of Studies in Washington, D.C.

Conference: Thomas Aquinas and the Greek Fathers

The Thomistic Institute and The Aquinas Center for Theological Renewal at Ave Maria University are co-sponsoring a conference this January on "Thomas Aquinas and the Greek Fathers." The conference will include presentations by Khaled Anatolios (University of Notre Dame), Joseph Wawrykow (University of Notre Dame), and Marcus Plested (Marquette University), among several others.

The conference will take place at Ave Maria University in Ave Maria, Florida from January 26th-January 27th. 

The conference is open to submissions pertaining to its theme. The "Greek Fathers" for each of the papers is understood quite broadly, such as a single Greek Father in relation to Aquinas, a theological topic in Greek patristics that would be particularly fruitful in dialogue with Aquinas, Aquinas's own research into the Greek Fathers, the debate in the 20th century (and today) in historical theology regarding scholastic and ressourcement principles, or matters of theological methodology more broadly involving Greek patristics and Thomism.

The deadline to submit inquiries for the TI and Ave Maria University's January conference "Thomas Aquinas and the Greek Fathers" is August 1st. Those interested in presenting a paper should email by that date with a title, a summary of their proposed paper, and their institutional affiliation. For more information visit

New Book from Our OWn Fr. Dominic Legge, OP:

The Trinitarian Christology of St. Thomas Aquinas 


Noted Thomist Fr. Gilles Emery (Ordinary Professor of Dogmatic Theology at the University of Fribourg) writes in the preface: 

"Dominic Legge’s book needs no recommendation beyond itself: all its readers will be able to confirm the high value of this research, the conclusions of which are solidly based on a rigorous reading of the texts of Thomas Aquinas. This work demonstrates the essentially Trinitarian structure of the Christology of St. Thomas.  It . . . constitutes henceforth the reference work on the subject. . .  Legge's book brings freshness and new life to our understanding of the Christology of Thomas Aquinas, because it successfully restores to its primacy the trinitarian approach that guides the theology of the Dominican master."  

Fr. Legge is the Assistant Director of the Thomistic Institute and is Assistant Professor in Dogmatic Theology at the Pontifical Faculty of the Immaculate Conception at the Dominican House of Studies.  

The book is available on Amazon in hard copy (and for for Kindle) and can be ordered directly from Oxford University Press.
