The Thomistic Institute - Invidious

The Thomistic Institute

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.

Founded in 2009, the Thomistic Institute is part of the Pontifical Faculty of the Immaculate Conception at the Dominican House of Studies in Washington, DC.

Our YouTube channel features Aquinas 101, a series of free video courses that help you to engage life’s most urgent philosophical and theological questions with the wisdom of St. Thomas Aquinas.
