The seven heavenly virtues were inspired from the Psychomachia ("Contest of the Soul"), an epic poem penned by Aurelius Clemens Prudentius (c. AD 410) that depicted a conflict between noble virtues and wicked vices. These are the seven virtues: chastity, temperance, charity, diligence, patience, and fortitude. Chastity refers to the quality of being chaste, or not having sexual relations before marriage. It is the absence of sexual immorality. Chastity is important because it prevents sexual abuse, ensures that pregnancies occur within marriage, and reduces the risk of contracting sexually transmitted diseases. Temperance involves controlling one's desires so as not to act on them. It means doing what is necessary not to indulge in something even if you want to. For example, if you want to eat ice cream every day after dinner, but know that this will make you obese, then not eating it is demonstrating self-control over your temperate desire for ice cream. Charité is kindness toward others. It includes helping people in need, volunteering one's time, and providing comfort to those who are suffering. Diligence is hard work. It means using effort and attention to accomplish something. For example, if you go to school at night and study hard, that is showing diligence. If you play soccer all year long without a break and don't sleep much, that is showing diligence.
