Original Sin: "The universal sinfulness of the human race (except for Jesus and--for Roman Catholics--Mary) originated by Adam and Eve and transmitted to their posterity. Some languages actually use the term inherited sin for original sin, though it is questionable whether sin can be inherited. Philosophical problems raised by this doctrine include questions as to the relation of Adam and Eve to later humans and the responsibility and freedom of those later individuals. Some distinguish between the sinfulness or predisposition to sin that is inherited and actual sin."
