The Sin section of our glossary explores the idea of wrongdoing and moral mistakes as seen in Christian beliefs. Here, we break down different types of sin, starting with Original Sin, which suggests all people are born with a tendency to make mistakes, to the differences between serious (Mortal) sins and less serious (Venial) sins. We also talk about how sin affects not just individuals but society, through Social Sin and not doing what’s right (Sins of Omission), highlighting how our actions impact others and our own moral duties. By looking into these ideas, including our natural inclination to do wrong (Concupiscence) and the serious warning about the Sin Against the Holy Spirit, we encourage readers to think about how common sin is and the ongoing need for making amends and seeking forgiveness. This glossary section helps make these ideas clearer, aiming for a deeper understanding of our moral and spiritual lives.
