The Original Sin of Adam and Eve

The original sin of Adam and Eve refers to their disobedience to God's command not to eat from the Tree of Knowledge of Good and Evil, as described in the book of Genesis in the Bible. As a result of this sin, humanity inherited a tainted nature in need of regeneration and a proclivity to sinful conduct, in the Christian doctrine of original sin. Specifically, the belief is that Adam and Eve transmitted to their descendants human nature wounded by their own first sin and hence deprived of original holiness and justice , leading to a loss of free will except to sin.
