Graduate Certificate in Thomistic Studies

Program Overview

The Graduate Certificate in Thomistic Studies engages students in the study of the life, thought, and works of St. Thomas Aquinas, the patron saint of Aquinas Institute of Theology. The 18 credit hour Certificate is designed to engage students in a philosophical survey of Thomas while offering students the opportunity to discover the relevance of his thought for the modern world.

Referred to as the “Angelic Doctor,” Thomas’ synthesis of theology offers an ordered and comprehensive vision that enables students to think about how individual questions are related to the whole. Moreover, his method of addressing alternative answers rather than postulating only one answer stretches the thought process and models a methodology.

Program Details & Length

Much of St. Aquinas’ thought provides foundational principles utilized in the Church’s theology today. Observing the way Thomas incorporated the thought of his time into the questions of the Mystery of God revealed in Jesus Christ provides students with insight into the overall theological process, including its strengths and limitations, throughout history.

Students may complete the degree either on-campus in St. Louis or online synchronously. Here, students participate in classes as they happen in St. Louis via a video conferencing service and are an active part of the conversation and learning environment.

The Certificate takes three years to complete part-time. The curriculum is comprised of six courses offered in a three–year cycle of one course per semester.
