Catechesis: Original Sin

This means that from birth they are full of evil lust and inclination and cannot by nature possess fear of God and true faith in God. Moreover, this same innate disease and original sin is truly sin and condemns to God’s eternal wrath all who are not in turn born anew through baptism and the Holy Spirit. Rejected, then, are the Pelagians and others who do not regard original sin as sin in order to make human nature righteous through natural powers, thus insulting the suffering and merit of Christ.—AC II:1-3
