The claim that pride is the root of all sin is not a medieval invention but an ancient reading of the Fall itself. Augustine's Enchiridion traces the pride in Adam's sin across multiple dimensions — sacrilege, murder, spiritual fornication, theft — arguing that pride was not one element but the animating structure of every fault. John Cassian gave the monastic tradition its definitive analysis: pride is a pestilential disease that attacks the whole man, "not content to damage one part or one limb only," but destroying those who were already at the top of the virtues. Chrysostom's homilies return repeatedly to the inversion of credit that pride produces: perverse men ascribe their good deeds to themselves and their evil to God, when the true order is the opposite.
"From thy self thou hast the ill doing, from God thou hast the well doing. On the other hand, see perverse men, how preposterous they are. What they do well, they will needs ascribe to themselves; if they do ill, they will needs accuse God" — Augustine's identification of pride as the inversion of right attribution, taking credit for the good and deflecting blame for the evil.
"There is then no other fault which is so destructive of all virtues, and robs and despoils a man of all righteousness and holiness, as this evil of pride, which like some pestilential disease attacks the whole man, and, not content to damage one part or one limb only, injures the entire body by its deadly influence, and endeavours to cast down by a most fatal fall those who were already at the top of the tree of the virtues" — Cassian's analysis of pride as uniquely comprehensive in its destruction.
