We believe that through the disobedience of Adam original sin is extended to all mankind; which is a corruption of the whole nature and a hereditary disease, wherewith even infants in their mothers womb are infected, and which produces in man all sorts of sin, being in him as a root thereof, and therefore is so vile and abominable in the sight of God that it is sufficient to condemn all mankind. Nor is it altogether abolished or wholly eradicated even by regeneration; since sin always issues forth from this woeful source, as water from a fountain; notwithstanding it is not imputed to the children of God unto condemnation, but by His grace and mercy is forgiven them. Not that they should rest securely in sin, but that a sense of this corruption should make believers often to sigh, desiring to be delivered from this body of death.

Wherefore we reject the error of the Pelagians, who assert that sin proceeds only from imitation.
