The talk introduces the Catholic understanding of sin as an offense against love—often described in Scripture as “missing the mark”—and explains how original sin wounds human nature without destroying it. Fr. Will then clarifies the Church’s distinctions between mortal sin, venial sin, and moral imperfections or dispositions, emphasizing that sin is fundamentally a matter of the will and that healing and freedom come through Christ and the sacraments, especially reconciliation.

The session concludes by laying the groundwork for moral decision-making through the three fonts of morality (object, intention, circumstances), showing how acts are judged as good or evil and why some acts are intrinsically evil—wrong always and everywhere—regardless of intention. Throughout, the teaching is presented with a pastoral clarity that distinguishes judging actions from judging persons, encouraging both truth and mercy as Christians seek holiness and real freedom in Christ.
