Sin, in religious teaching, is any lack of holiness, any defect of moral purity and truth, whether in heart or life, whether of commission or of omission. Transgression, as its etymology indicates, is the stepping over a specific enactment, whether of God or man, ordinarily by overt act, but in the broadest sense in volition or desire. Sin may be either act or state; transgression is always an act, mental or physical. Crime is often used for a flagrant violation of right, but in the technical sense denotes specific violation of human law. Depravity denotes no act, but a perverted moral condition from which any act of sin may proceed. Immorality denotes outward violation of the moral law. Compare OFFENSE. Antonyms: decorum, godliness, goodness, holiness, integrity, morality, purity, right, righteousness, sinlessness, uprightness, virtue. Compare synonyms for VIRTUE.
