How do you define it, since it is not actually mentioned in Scripture. My pastor preached on this Sunday, and he holds to the Augustinian view of it, which seems like everyone born would be bound to hell apart from commiting their own sin, even infants and the MRDD. I understand eveyone born inherits a sin nature, but I have a hard time Scripturally with the notion that infants and the MRDD can knowingly break God's Law. I believe all men die a physical death because of sin, but I do not see in the Bible where it shows hell being the punishment for infants and the MRDD who die. from wikipedia.org... The notion of original sin as interpreted by Augustine of Hippo was affirmed by the Protestant Reformers Martin Luther and John Calvin. Both Luther and Calvin agreed that humans inherit Adamic guilt and are in a state of sin from the moment of conception. This inherently sinful nature (the basis for the Calvinistic doctrine of "total depravity") results in a complete alienation from God and the total inability of humans to achieve reconciliation with God based on their own abilities. Not only do individuals inherit a sinful nature due to Adam's fall, but since he was the federal head and representative of the human race, all whom he represented inherit the guilt of his sin by imputation.
