What Is Sin According to the Bible?

Few religious words are as misunderstood as this one, so it is worth asking plainly: what is sin? In the Bible it is not primarily a list of forbidden pleasures. It is a description of a relationship gone wrong, with consequences that spread outward into every other relationship a person has.

Biblical Definitions

The Hebrew and Greek vocabulary is concrete and varied. The most common Hebrew term, chatta't, comes from an image of missing a target. Other words carry the sense of crookedness or twisting, and of rebellion, the deliberate breaking of a bond. The New Testament word hamartia also carries the sense of missing the mark, while other terms describe trespass, lawlessness, and debt.

Put together, these words describe something wider than misbehavior: a failure to be what one was made to be. Christian theology develops this into an account of sin as the rejection of a right relationship with God, expressed in actions, in settled habits of character, and in an underlying condition of human nature. The Stanford Encyclopedia of Philosophy entry on sin in Christian thought sets out these layers and shows why philosophers treat them as distinct questions.

The Story in Genesis 3

Christians traditionally trace the origin of the trouble to Genesis 3, the account of the man, the woman, the serpent, and the tree. Scholarly reference works note that the text itself never uses the words fall, temptation, or original sin, and never calls the act a sin. Those are later interpretive categories. What the story does describe, as the Society of Biblical Literature's reference entry on the Fall summarizes, is a disobedience rooted in the desire to be like God, after which the positive relationship between the humans and God is broken.

The consequences in the narrative are relational rather than abstract. The couple hide. They blame the serpent and each other. Work becomes toil, childbirth becomes painful, and death enters the picture. Paul later reads this story typologically, setting Adam alongside Christ as two representative figures with opposite effects on the human family.

Christians differ over how literally to read Genesis 3 and how much weight to place on inherited guilt as opposed to inherited weakness. Catholic, Orthodox, and Protestant traditions all affirm that something is genuinely wrong with humanity, while describing the inheritance differently.

Personal and Structural Sin

The Bible speaks about sin at more than one scale. There is the personal register: lying, greed, cruelty, betrayal, the sins a person can name and confess. There is also a corporate register. The prophets rail against dishonest scales, courts that favor the wealthy, and religion performed while the poor go hungry. Whole cities and nations are addressed as morally responsible.

Modern theology often calls this second register structural or social sin, meaning evil embedded in systems that outlive any individual and that shape people who never chose them. Both registers matter. Focusing only on personal sin can produce a private morality blind to injustice, while focusing only on structures can let individuals off the hook entirely.

Underneath both is a positive claim about human worth. Christian teaching holds that human beings are made in the image of God and that this dignity is damaged but never erased. The Catechism of the Catholic Church section on the human person states that of all visible creatures only man is able to know and love his creator, which is precisely why the distortion matters so much.

The Remedy

Christianity does not stop at diagnosis. The New Testament presents Jesus as the answer to the problem it describes: through his life, death, and resurrection, sin is forgiven and human nature begins to be restored. The response asked of people is repentance, a turning around, and trust.

Taken seriously, this makes the doctrine of sin oddly hopeful. It refuses to pretend that everything is fine, and it refuses to conclude that nothing can be done.
