Can someone explain me the notion of Original Sin? I simply don't understand it.
This question is primarily focused on the Christian notion of original sin. But any type of opinion and contribution is welcome, be it from a atheist, Christian or any other point of view.
Please stick to the subject though...
What a doofus I am! Here you are, asking 'what' the notion of original sin is. Heck - all anybody had to do was post what the Catholic Church had to say about it - which is,"
Original sin - an essential truth of the faith
388 With the progress of Revelation, the reality of sin is also illuminated. Although to some extent the People of God in the Old Testament had tried to understand the pathos of the human condition in the light of the history of the fall narrated in Genesis, they could not grasp this story's ultimate meaning, which is revealed only in the light of the death and Resurrection of Jesus Christ.261 We must know Christ as the source of grace in order to know Adam as the source of sin. The Spirit-Paraclete, sent by the risen Christ, came to "convict the world concerning sin",262 by revealing him who is its Redeemer.
389 The doctrine of original sin is, so to speak,
the "reverse side" of the Good News that Jesus is the Savior of all men, that all need salvation and that salvation is offered to all through Christ. The Church, which has the mind of Christ,263 knows very well that we cannot tamper with the revelation of original sin without undermining the mystery of Christ.
Now - do I agree with this? not a hope in hell, but that's not what you asked, is it? The Catholic Church that has decided to 'decide' on this original sin business is the one who should provide you with the technical answer to your question. All of us others? We're merely opinions!
