Professor of Theology and Catechetics


Sean Innerst is a Professor of Theology and Catechetics at the Augustine Institute and has been teaching theology, evangelization, and catechesis to seminarians; college students; Christ in the City Missionaries; FOCUS missionaries; graduate students; DREs and DEs; deacon candidates; and catechists and regular folks in many parishes and dioceses for over twenty-five years. He helped found two important Catholic institutions in Denver: St. John Vianney Theological Seminary, as founding provost, and the Augustine Institute, as its founding academic dean.

He has given hundreds of presentations, written many articles, and contributed to a number of books, primarily on the topics of evangelization, catechetical content and methodology, matrimony, and St. Augustine, but also on Marian and other theological themes, as well as on the topics of classical education, friendship, and Church magisterial documents.  He is the author of Pillars: A Journey Through the Catechism and From Blessing to Blessing: The Catechism as a Journey of Faith (both from Ascension Press) and the four-part series Ladder of Ascent, a two-year course on the Catechism of the Catholic used in a number of dioceses in the U.S.

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.
