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.
Our salvation is based not on merit but on God's mercy. It has nothing to do with how many Hail Marys we recite, or how much money we donate or how many homeless shelters we build. You can't earn ot buy you way to Heaven!.
If I believe that God can save people thieves who, at their last moment repent, or me who was an unbeliever for many years, or somone like Saint Paul, who was guilty of stoning Christians, I have every reason to believe that God's mercy will prevail over those who have never sinned.
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.
Just wondered how she is...I have been trying to offer my miserable prayers for her when I remember.
