Admitting You're a Sinner

[vulcanlogician]

And the Catechism of the Catholic Church says what, regarding Original Sin?

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 Saviour 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.

There's more on it in there, much more... but this is basic I think.
