Christianity and Judaism
In contrast to the Jewish view of being morally balanced, Original Sin refers to the idea that the sin of Adam and Eve's disobedience (sin "at the origin") has passed on a spiritual heritage, so to speak. Christians teach that human beings inherit a corrupted or damaged human nature in which the tendency to do bad is greater than it would have been otherwise, so much so that human nature would not be capable now of participating in the afterlife with God. This is not a matter of being "guilty" of anything; each person is only personally guilty of their own actual sins. However, this understanding of original sin is what lies behind the Christian emphasis on the need for spiritual salvation from a spiritual Saviour, who can forgive and set aside sin even though humans are not inherently pure and worthy of such salvation. Paul the Apostle in Romans and I Corinthians placed special emphasis on this doctrine, and stressed that belief in Jesus would allow Christians to overcome death and attain salvation in the hereafter.
Seven deadly sins
Pope Gregory combined this with "tristitia" into sloth for his list. When Thomas Aquinas described "acedia" in his interpretation of the list, he described it as an "uneasiness of the mind", being a progenitor for lesser sins such as restlessness and instability. Dante refined this definition further, describing acedia as the "failure to love God with all one's heart, all one's mind and all one's soul"; to him it was the "middle sin", the only one characterised by an absence or insufficiency of love. Some scholars have said that the ultimate form of acedia was despair which leads to suicide.
