<P> Original sin , also called ancestral sin , is a Christian belief of the state of sin in which humanity exists since the fall of man , stemming from Adam and Eve 's rebellion in Eden , namely the sin of disobedience in consuming the forbidden fruit from the tree of the knowledge of good and evil . This condition has been characterized in many ways , ranging from something as insignificant as a slight deficiency , or a tendency toward sin yet without collective guilt , referred to as a `` sin nature '' , to something as drastic as total depravity or automatic guilt of all humans through collective guilt . </P>
