This teaching explores the nature of sin, the importance of contrition, and how to properly prepare for the Sacrament of Confession. It explains the difference between original sin and personal sin, as well as mortal and venial sins, and how each affects our relationship with God, others, and ourselves. The talk emphasizes the role of true sorrow—both perfect and imperfect contrition—and clarifies that repentance is an act of the will, not just a feeling. It also provides practical guidance on examining one’s conscience, confessing sins clearly, and approaching confession with humility, honesty, and a desire for spiritual renewal.
