Visitor: There are some issues that original sin bring up. Is it moral to punish everyone for a sin committed by Adam and Eve? Or do you consider the passage to be an allegory ? Excessively harsh punishments are immoral. For example if a man stole a loaf of bread would it be moral to put him in jail for life? The sins that one may commit in his or her life are not bad enough for eternal damnation. It does not seem right that God would create man imperfect and punish him forever for not having the ability to be perfect.
Response: It is not reasonable or coherent to call God immoral unless you can point to an absolute standard of morality that is greater than He. The whole concept of immorality requires a standard to appeal to, or you are only giving a personal preference which has zero authority. So anyone who claims NOT to believe in God and yet appeals to moral absolutes which He should be subject to is being inconsistent with his relativism and committing intellectual suicide. He reveals deep down he knows there is a just God.
Also, it does not follow that if God created man with the ability to make voluntary choices that He "created man imperfect." God declared his creation of Adam and Eve to be "very good".
As for excessive punishment ... if you sin against an infinitely holy God by your rebellion against Him then you are working with an entirely different idea than if you merely sinned against a man. Eternal damnation is not the result of man merely stealing a loaf of bread but of putting ourselves in the place of God as the ultimate authority. All sin is a direct challenge to the first commandment - a rejection of Him as our parent and His authority. And we continue to sin and rebel against God's authority -- as if we were cheering Adam on in his sin against God. Our sinful actions demonstrate that we are sons of Adam and maintain solidarity with him.
