The Canons of the Council of Orange (529 AD) - CANON 2

CANON 2. If anyone asserts that Adam's sin affected him alone and not his descendants also, or at least if he declares that it is only the death of the body which is the punishment for sin, and not also that sin, which is the death of the soul, passed through one man to the whole human race, he does injustice to God and contradicts the Apostle, who says, "Therefore as sin came into the world through one man and death through sin, and so death spread to all men because all men sinned" (Rom. 5:12).
