Part II · Sin, Law, and the Need for a Savior
ἁμαρτία
Hamartia
sin, missing the mark
“Sin as Act and Power”
The word sin gets used a lot of ways in English that it does not carry in Greek. We talk about “sinful” chocolate cake and “sinful” indulgences and the “sin” of skipping the gym. The word has gone soft on us. By the time it reaches the Sunday liturgy where we confess that we are “by nature sinful and unclean,” a fair share of the congregation is quietly wondering whether the wording is not a touch overstated.
It is not overstated. It is not even strong enough.
The Word
ἁμαρτία (hamartia), pronounced hah-mar-TEE-ah. A first-declension feminine noun. The verb form is hamartanō — to sin, to do wrong.
You will sometimes be told that hamartia comes from a root meaning “to miss the mark” — an archery term, picturing an arrow that has gone wide of its target. That etymology is real. It is also where most lay treatments of hamartia stop, and where most of the trouble starts.
Words do not mean what their etymology says they mean. (See the introduction on the root fallacy.) Even if hamartia started life as an archery word, by the time Paul reaches for it in Romans it is doing far more theological work than “I aimed and missed” can carry. The archery picture is in the family tree of the word. It is not the word.
Range of Meaning
In its New Testament usage, hamartia covers a wider field than English “sin” usually does. The range includes at least:
- A specific wrong act. One sin, one occurrence. “Everyone who commits hamartia is a slave of hamartia” (John 8:34).
- The condition or state of sinfulness. Not just acts but the orientation behind them.
- Sin as a power. This is the one English readers most often miss. In Romans especially, Paul personifies hamartia as an active agent. It “reigns” (Rom 5:21), it “dwells in” people (Rom 7:17), it “produces death” (Rom 7:13). Paul writes about sin the way a doctor writes about a disease that is not just present but actively at work.
- The guilt and burden of sin — the weight that has to be taken away. “Behold, the Lamb of God, who takes away the hamartia of the world” (John 1:29).
- In the background, from the Septuagint, the Hebrew chatat — which can mean either a sin or the sin-offering made to cover it.
The English word “sin” can carry several of these, but rarely all at once, and rarely as forcefully. When Paul uses hamartia, the context will usually point toward one of these senses — but the others are present in the family of meanings the word brings with it.
Here is something your English Bible cannot easily show you. When Paul writes about sin as a power, he very often puts the definite article in front of it — hē hamartia, “the Sin,” the way you would name a person or a country. English has no graceful way to carry that. “The sin came into the world” sounds like a typo, so translators quietly drop the article and print “sin came into the world” (Romans 5:12). But the article is doing real work. Paul is not talking about your sins, plural, the items on the list. He is talking about Sin, singular — a power that got loose in the world through one man and has been running the place ever since. Read Romans 5 through 7 watching for that little word hē, and a character walks onto the stage: Sin enters, reigns, seizes territory, deceives, pays wages, kills. It is the difference between reading a police blotter and reading about an occupying army.
Where You’ll Meet It
Some of the most important New Testament occurrences:
“For all have sinned and fall short of the glory of God.” (Romans 3:23, ESV)
The verb form (hēmarton) here, not the noun, but the family is the same. The all-have-sinned verse is the diagnostic floor: there are no exceptions.
“For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.” (Romans 6:23, ESV)
Hamartia as the employer who pays in death. The personification is already at work.
“For sin will have no dominion over you, since you are not under law but under grace.” (Romans 6:14, ESV)
Read this next to verse 23 and the picture sharpens. Sin is not only an employer who pays in death; it is a would-be lord. The verb Paul uses for “have dominion” is kyrieuō — the verb built on kyrios, “lord” (Chapter 3). Paul’s promise here is not mainly that you will behave better. It is that you have been moved out from under one lordship and set under another. The Christian life is not sin’s dominion carefully managed; it is sin’s dominion broken, and a new Lord in the house.
“So now it is no longer I who do it, but sin that dwells within me.” (Romans 7:17, ESV)
This is the verse where Paul shows you that hamartia is not only things you do. It is something that lives in you and acts. You cannot read Romans 7 honestly and come away thinking sin is only a list of bad behaviors.
“For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God.” (2 Corinthians 5:21, ESV)
The great exchange. The one who knew no hamartia is made hamartia for us. Lutherans read this as the most concentrated statement of substitutionary atonement in the New Testament. (We return to this verse in Chapter 22, on hyper.)
“If we say we have no sin, we deceive ourselves, and the truth is not in us.” (1 John 1:8, ESV)
John writes to baptized Christians. Notice what he says — not “if you sinned once, repent and you will have no more sin.” He says if we claim to have no sin, we are lying. The baptized Christian still has hamartia. This is the verse Lutherans point to when they speak of the simul.
What Confessional Lutherans Hear
Hamartia — sin, missing the mark
In hamartia the confessional Lutheran ear catches two notes at once.
First, hamartia is more than acts. It is a condition we are born into. This is what the Confessions call original sin. The Augsburg Confession, Article II, puts it bluntly: all human beings since Adam are born “with sin, that is, without fear of God, without trust in God, and with concupiscence.” That is not a list of bad behaviors. It is a description of what we are before we do anything.
Roman Catholic theology, since the Council of Trent, has tended to treat the disordered desire that lingers in the baptized Christian — concupiscence — as not-quite-sin: the tinder for sin, perhaps, but not sin itself. Lutherans say concupiscence is sin, and the Apology of the Augsburg Confession spends the whole of its second article making the case. It is worth knowing why the Reformers dug in here. If concupiscence is only tinder and not sin, then something in me is still fundamentally sound, and the gospel has only to top up what I cannot quite finish on my own. If concupiscence is sin — if the disorder goes all the way down — then I need a Savior for my nature and not merely for my record. The diagnosis is more severe because the disease is, and the severity is not cruelty. It is the precondition for a gospel large enough to actually save.
Second, hamartia remains in the baptized Christian. Simul iustus et peccator — at the same time righteous and a sinner. The Reformed tradition often speaks of progressive sanctification in a way that suggests sin is gradually being uprooted in the believer, the sinner shrinking year by year until little is left. Lutherans are more sober, and — strangely — more comforted. The simul is not a measurement. It is not that I am forty percent saint and sixty percent sinner, with the ratio slowly improving. It is that I am, at one and the same time, wholly righteous and wholly a sinner. Wholly righteous, because the righteousness that saves me is Christ’s, reckoned to me, entire and outside myself — it is not a quantity in me that could rise or fall. Wholly a sinner, because the old Adam is still in the house, and he does not need to be invited. He stays.
This is why the comfort holds. If my standing before God rose and fell with how much of the sinner had been burned off, I could never have a quiet conscience; I would spend my life taking my own spiritual temperature. But because the righteousness is Christ’s and complete, the sin that remains — real as it is — cannot unseat me. So we live in daily repentance, daily return to baptism, daily reception of the absolution — not because we are clawing our way toward a sinlessness we might someday reach, but because daily we are sinners, and daily the word of forgiveness is spoken over sinners, and that word is enough.
Both of these notes rest on the word’s deepest register — the one the chapter’s title reaches for: hamartia is a power, and not only a debit. If sin were merely a record of acts, salvation could be merely the erasing of the record — pardon, and nothing more. And pardon is real; the forgiveness of sins is the beating heart of the gospel. But because hamartia is also a reigning power, salvation is also a rescue. Christ does not only cancel what sin charged against us; He goes down into sin’s own territory, dies under its full weight, and rises having broken its dominion — and in baptism He carries us across the border, out of the kingdom where Sin is lord and into the kingdom where He is (Romans 6:1–11). This is why Lutherans refuse to choose between the courtroom and the battlefield. Sin is guilt to be forgiven and a tyrant to be defeated; the cross is both an acquittal and a liberation. Hold only the first and the Christian life shrinks to bookkeeping. Hold only the second and you lose the conscience-settling word of pardon. The word hamartia, heard in full, will not let you set down either one.
The pastoral payoff: when you confess together with your congregation that you are “by nature sinful and unclean,” you are not exaggerating. You are not being theatrical. You are telling the truth about yourself in the only words that the gospel actually answers.
