The seminar presents the entire doctrine of anthropological development, drawn from the second part of the Summa Theologica, showing the supernatural structure that culminates in the theological virtues as the crowning of the life of grace. It will examine the essence of virtues, vices, and sin, considered from the perspective of grace as the center of the supernatural life, as well as the reasons for their disappearance. Additionally, the seminar will briefly consider the theological virtues in particular and the opposing vices, as well as the gifts of the Holy Spirit as explained by St. Thomas in the initial questions of the Secunda Secundae of the Summa Theologica.
