The seven deadly sins are pride, envy, gluttony, lust, anger, greed and sloth.Christian philosophers and theologians have debated these qualities, also known as the capital vices or cardinal sins, for centuries.
Most Christian texts declare that pride is the most serious of the sins and the source of all other sin. Pride is a belief that one is superior to others and results in a failure to respect others' accomplishments. Pride also interferes with a person's recognition of God's supremacy.
Many Christians consider pride to be an especially deadly sin, because they believe that it was through pride that Lucifer (Satan) lost his place in heaven, and that it was also through the prideful desire to be like gods that Adam and Eve ate the fruit of the tree that God had forbade them to eat.
Many of the cardinal sins arise from desire that becomes unhealthy and all-consuming. Envy implies a desire for the traits, abilities, status, accomplishments or rewards of others. Though people most commonly associate it with food, gluttony is the excessive desire for anything to the point of waste. Lust also indicates an unhealthy desire, specifically for pleasures of the body. Lust can also refer to other desires, such as money, fame or power, but most commonly it refers to a desire for sex.
Lust likewise is a grave sin according to many theological systems. The sin of lust consists of willfully pursuing sexual pleasure outside the order of reason and outside of the order established by God.
Anger refers to uncontrolled feelings of rage and hatred. Anger can also manifest itself as impatience or revenge. Greed refers to the excessive pursuit of material wealth, turning away from God in favor of temporary possessions. Sloth is the practice of avoiding either spiritual or physical work, and it refers to both conventional laziness and to a refusal to develop spiritually.
