Moral Theology

A lecturer speaks at a podium in a semicircular classroom. Attentive students listen, seated at long desks. The room has a relaxed, studious vibe.

What does Jesus say about the good life?

June 8–12, 2026

A group of people seated in a classroom appears engaged and amused during a presentation. The atmosphere is light and attentive, with smiles and focused expressions.

This course helps students answer that most important question, What is the good life? It takes its cue from Jesus’s teaching on the beatitudes and gives special attention to the virtues and the gifts of the Spirit. This course is a systematic treatment of moral theology, laying down those First Principles from which moral theology proceeds. This course explores Aristotelian moral philosophy and its appropriation by the Great Tradition on subjects such as natural law, virtue, etc. To that end, this course contrasts classical and modern approaches to moral theology. As a course in practical theology, the scope is twofold: we will ask how moral theology should inform the active life (especially in the Anglican Church), as well as the Christian’s engagement with this secular age.

Dr. Matthew Barrett

Research Professor of Theology

When the Lord opened Dr. Matthew Barrett's eyes to the truth and beauty of Anglicanism, he did not know God was preparing a place for him at Trinity. As a systematic theologian, he believes God has called him to share the riches of classical theology with students so they may be God's gifts in the Anglican church. As theologian-in-residence of Anselm House at St. Aidan's Anglican Church, he mentors Anselm Fellows through reading the Great Tradition and Socratic dialogue.

Dr. Barrett teaches theology as preparation for the beatific vision, where students will gaze upon the beauty of the Lord. He teaches God's Word with the wisdom of the Great Tradition so students might feed Christ's church with word and sacrament. He is currently writing a Systematic Theology for seminary students, which will be followed by a Philosophical Theology given his expertise in Thomiastic metaphysics. His scholarship includes Simply Trinity, The Reformation as Renewal, and None Greater. He serves as editor-in-chief of The Journal of Classical Theology and Credo Magazine.

What Dr. Barrett loves most is seeing theology come alive in Trinity's liturgical life through morning and evening prayer and the Eucharist. His goal is to train students to be the best Anglicans they can be. Originally from California, he's a Lakers and Dodgers fan, married to Elizabeth, and father to four Chiefs fans: Cassandra, Georgia, Charlie, and Lorelei.
