Theological Institute of St. Thomas Aquinas (“Thomisticum”)



The general mission of the Theological Institute of St. Thomas Aquinas (aka “Thomisticum”) is to help transmit the treasury of the “Golden Age” of Scholastic Theology to the faithful of The Proto-Cathedral of St. James the Greater, whose circumstances preclude them from engaging in a formal degree program in Thomistic theology, yet have a strong desire to learn the truths of the Catholic Faith in a deeper way, than what secondary school catechesis – and in most cases, university-level studies – can or will provide.

The proximate goal of the Institute is to help foster an appreciation and deep respect for the teachings of St. Thomas Aquinas, whose hope was to provide a method of pursuing Christian theology in a clear and concise manner, in order to lead the faithful toward a better understanding of God and man, so that, by grace, a closer and less esoteric relationship with our Lord, Jesus Christ might be had.

The Institute’s remote goal is to help lead its students through a careful reading of the entire Summa Theologiae of St. Thomas Aquinas.  Upon accomplishing this task, it is hoped that those who began as beginners in theology, will then progress into more advanced studies of the Catholic Faith, and by utilizing the broad corpus of Aquinas’ works, may become teachers of Catholic truth in their own right, whether within their domestic church, everyday encounters, parish ministries, or as professional theologians.
