The Augustine Institute Graduate School is committed to the pursuit of wisdom in service of Catholic mission. All of our academic programs therefore seek, first, to allow students to make their own “all the treasures of wisdom and knowledge” (Col. 2:3), which are found in Christ and passed down in the Sacred Tradition of the Catholic Church. Second, our programs prepare students to hand these treasures on to others effectively through evangelization and catechesis.
