Either the sin committed by Adam as the head of the human race, or the sin he passed onto his posterity with which every human being, with the certain exception of Christ and his Mother, is conceived and born. The sin of Adam is called originating original sin (originale originans); that of his descendants is originated original sin (originale originatum). Adam's sin was personal and grave, and it affected human nature. It was personal because he freely committed it; it was grave because God imposed a serious obligation; and it affected the whole human race by depriving his progeny of the supernatural life and preternatural gifts they would have possessed on entering the world had Adam not sinned. Original sin in his descendants is personal only in the sense that the children of Adam are each personally affected, but not personal as though they had voluntarily chosen to commit the sin; it is grave in the sense that it debars a person from the beatific vision, but not grave in condemning one to hell; and it is natural only in that all human nature, except for divine intervention, has it and can have it removed only by supernatural means.
