When "Original Sin" is dicussed one needs to carefully define terms not only in a theological but pragmatic way.
I realized this in the Baptist Only Forums when it was said that I held to an Augustinian/Catholic view of said doctrine.
However anyone who accepts this version of Original Sin also believes that water baptism takes away Original Sin.
Without water baptism to remove "Original Sin" there can be no doctrine of Augustinian/Latin Church "Original Sin".
My own view is that Adam (the original human sinner) passed on to all of us all the necessary equipment and ability to sin which inevitably each of us will do given the maturity of discerning good and evil.
John 3
17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved.HankD
18 He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.
19 And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil.
20 For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved.
Infant baptism is really a waste of water and time. First, those cast into hell are cast in there only after judgment "according to" their own personal works. Dying infants have no individual personal works to be judged. None are judged or cast into hell for anything other than their own personal individual works.
John 1:29 says that Jesus took away the "sin" (singular) of the world and therefore no one is brought before the judgement seat of God and condemned to hell because of Adam's sin. They are brought before judgement and condemned according to their own willful sin. Christ paid the eternal penalty for Adamic Sin. He did not remove the immediate and temporal consequences of sin and death.
I believe that dying infants are redeemed from sin exactly as they were condemned by sin. Adam acted in their behalf and Christ acted in their behalf. Where sin abounded grace did much more abound. What was lost in Adam much more was gained in Christ. I believe the number in heaven will out number those in hell.
