Catholic Catechism:
1263
By Baptism all
sins are forgiven, original sin and all personal
sins, as well as all punishment for sin. In those who
have been
reborn nothing remains that would impede their entry into
the
Kingdom of God, neither Adam's sin, nor personal sin, nor
the
consequences of sin, the gravest of which is separation
from God.

As a result of
original sin, human nature is weakened in its
powers, subject to ignorance, suffering and the
domination of death,
and inclined to sin (this inclination is called
"concupiscence").
1714
Man, having been wounded
in his nature by
original sin, is
subject to error and inclined to evil in exercising his
freedom.

"When we made
our first profession of faith while receiving the
holy Baptism that cleansed us, the
forgiveness we received then
was so full and complete that
there remained in us absolutely
nothing left to efface, neither
original sin nor offenses
committed by our own will, nor was
there left any penalty to
suffer in order to expiate them. . . . Yet the grace of
Baptism
delivers no one from all the weakness of nature. On the
contrary,
we must still combat the movements of concupiscence that
never
cease leading us into evil "
