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.

New book from fr. thomas joseph white, op

Coming soon from Catholic University Press, Fr. Thomas Joseph White's new book is an excellent introduction for young professionals with no specialized background in theology who are interested in learning more about Catholicism, or as an introduction to Catholic theology. It will also serve as a helpful text for theology courses in a university context. 

As Fr. White states in the book's introduction: "This is a book that offers itself as a companion. I do not presume to argue the reader into the truths of the Catholic faith, though I will make arguments. My goal is to make explicit in a few broad strokes the shape of Catholicism. I hope to outline its inherent intelligibility or form as a mystery that is at once visible and invisible, ancient and contemporary, mystical and reasonable."
