The seven deadly sins date back to the late sixth century, when Pope Gregory the Great reduced the worst sins man can make to seven ones. These sins include greed, pride, sloth, wrath, gluttony, lust and envy.
Prior to the seven deadly sins were eight sins that Evagrius of Pontus believed to be the worst offenses a human could make. They included gluttony, lust, avarice, sadness, anger, acedia, vainglory and pride, in order of how serious they were. Pride was considered the worst offense, while gluttony was the least severe. When they developed into the seven deadly sins, they were not given in order of severity, as all were considered equally offensive.
