[Hermann the Cherusker]

Orthodoxy does not believe in the "original sin" as something we inherit; we inherit mortality and propensity to commit sin as a consequence of Adamn's sin, and not the sin inself.

That's exactly what Catholicism teaches.

Original sin is the death of the soul. It is the absence of grace and the lack of a connection to the divine life of God in Christ in every newborn person.

It is not a personal or actual sin for anyone besides Adam and Eve.

Don't confuse our legalistic terminology like guilt, stain, merit and the rest for things that they are not.

Well, then, there is no argument.

But that does not tell me why the Catholics then need the Limbo. We are to be judged for that which we have done. The unbaptized infants had done nothing to be judged for, nor anything to repent for. Do you not think that God in his infinite love for humanity can not find room for Grace for unbaptized infants if he can save repentant murderers? Better yet, why speculate and confuse, as if we really know the essence of God's salvation?!
