Mit Brennender Sorge §25

²⁵ "Original sin" is the hereditary but impersonal fault of Adam's descendants, who have sinned in him ( Rom. v. 12). It is the loss of grace, and therefore of eternal life, together with a propensity to evil, which everybody must, with the assistance of grace, penance, resistance and moral effort, repress and conquer. The passion and death of the Son of God has redeemed the world from the hereditary curse of sin and death. Faith in these truths, which in your country are today the butt of the cheap derision of Christ's enemies, belongs to the inalienable treasury of Christian revelation.
