Yeah, but what do Catholics really believe, is original sin, by itself, enough to condemn a man? This part of the Catechism does not appear to say so, but my understanding was that Catholics believe that men need a savior from conception. Is the official Roman Catholic position that no one needs a savior until the first mortal sin after reaching the age of reason? That would be news to me. Good Catholic Freepers have told me otherwise.
Catholic Baptism is sealed with the Spirit at the age of reason. That would suggest that children until that time are innocent. The Orthodox baptize with water and seal with the Spirit at the same time, but I have never heard any Orthodox authority say that children are "sinful."
No, original sin does not condemn alone. It is what in modern language we’d call genetic condition, predisposing men past the age of reason commit actual sin through the operation of their free will.
When actual sin is avoided, that is possible through the divine grace, which is here because of the work of the Savior. Baptism removes original sin and opens the channel of sanctifying grace available to the baptized through the other sacraments of the Church.
