 Although earlier Christian authors taught the elements of physical death, moral weakness, and a sin propensity within original sin, Augustine was the first Christian to add the concept of inherited guilt ("reatus") from Adam whereby every infant is born eternally damned and humans lack any residual ability to respond to God.Reformed theologians emphasize that this sinfulness affects all of a person's nature, including their will.This view, that sin so dominates people that they are unable to avoid sin, has been called total depravity.
