On Predestination and the Doctrine of Sufficient and Efficacious Grace in St. Thomas Aquinas
Dr. Taylor Patrick O’Neill

In this lecture, Taylor Patrick O’Neill gives a brief introduction to St. Thomas Aquinas’ doctrine of predestination with a special focus on how it relates to human freedom. Principles of a Thomistic understanding of providence provide a necessary backdrop for understanding election and reprobation while principles of a Thomistic understanding of grace provide a foundation for exploring the differences between election and reprobation, as well as a defense of contingency and authentic human freedom.
Additional attention is paid to the distinction of sufficient and efficacious grace in the Thomistic tradition.
