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 Dominican House of Studies in Washington, D.C.
