Original Sin
Definition
The fallen state inherited by all humanity from the first sin of Adam and Eve — a deprivation of original holiness, not a personal fault.
Original sin is "contracted, not committed" (CCC 404). Human nature is not totally corrupted, but wounded: subject to ignorance, suffering, death, and an inclination to sin called concupiscence (CCC 405). Baptism erases original sin and restores the life of grace, though its consequences remain as a struggle.
