Theology 101 is a weekly group that is led by the Dominican Brothers. The Dominicans choose a topic for the semester and teach and lead discussion with students. Past topics have included Theology of the Body, On Love of God and The Civilization of Love, and Catholic Social Teaching.
The Thomistic Institute, an organization that is also connected to the Dominican Order, hosts several talks each year that focus on Catholic philosophy. Email TI@catholicterps.org for more info!
