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.
Christianity and Judaism
Catholicism categorizes sins into various groups. A wounding of the relationship with God is often called venial sin; a complete rupture of the relationship with God is often called mortal sin. Without salvation from sin (see below), a person's separation from God is permanent, causing such a person to enter Hell in the afterlife. Both the Catholic Church and the Orthodox Church define sin more or less as a "macula", a spiritual stain or uncleanliness that constitutes damage to man's image and likeness of God.
