a slave: a person legally owned by another and wholly at that owner's disposal
TranslatabilityPartialCertaintyStrong
In the ordinary speech of the first century this word named one thing: a human being who was someone else's property. A slave had no claim on his own time, body, or future; everything he had and did belonged to a master. That hard fact is the bedrock of every use of the word in the New Testament. It is why a softer English word like "servant" misses the point, since a servant is hired and free to leave, while a slave is owned.
The striking thing is that the New Testament takes this lowest of social positions and turns it into one of its richest pictures. The same word that named a person without rights becomes the proud title the apostles claim for themselves before God and Christ, the way Paul describes the human heart's bondage to sin, and even the shape Christ himself took on when he became human. In every case the core idea holds steady: total belonging, with no part of the self held back. What shifts is who owns whom, and whether that ownership is a tragedy or the truest freedom.
The senses below sort the occurrences by which kind of belonging is in view, but they are shades of one concept, not separate words. A reader who keeps "owned by another" in mind will follow the word everywhere it goes.

What "taking the form of a slave" points to is debated. Some read it as a direct echo of the suffering Servant of Isaiah 53 (Ralph Martin, Bockmuehl); others read it as simply Christ's acceptance of the human condition under death and the cosmic powers, with the contrast being between God's form and a slave's form rather than a specific Isaiah allusion (Gordon Fee); a third reading stresses the concrete social degradation of slave status, culminating in crucifixion, the death typically reserved for slaves (Hellerman, drawing on Hengel).

How doulos differs from similar Greek words
διάκονοςa διάκονος is a commissioned agent who carries out a task for someone, often with real standing; the word names the job, not ownership, whereas δοῦλος names who owns the person regardless of the task.
Names a person who is owned and bound to a master, set against being free and standing in a household under an owner's authority. The relationship of ownership, not just the act of serving, is the whole point.1Co 7:21Gal 3:28Eph 6:5
Drives the master-and-slave parables, where the slave belongs body and time to a lord who can reward, punish, or reckon accounts with him.Mat 18:27Mat 25:21Luk 17:7
Pictures total belonging in the moral and spiritual realm: a person is the slave of sin, or set free to become the slave of righteousness and of God, owned by whatever he obeys.Jhn 8:34Rom 6:16Rom 6:17
Both
Both can name someone wholly given over to God or Christ, which is why the New Testament writers use them side by side; the slave word stresses belonging to the Lord while the servant word stresses the work done in his name.Php 1:12Co 11:23
Names the work of serving and the office of one who serves, with the focus on the people helped rather than on who owns the worker. It is the word for a minister of the gospel and for the office of deacon in a church.1Ti 3:8Eph 3:7Col 1:7
Marks greatness as Jesus redefines it: the one who would be great must become the servant of all. The point is active usefulness to others, not low social rank.Mat 20:26Mat 23:11Mrk 10:43
Used for someone who carries out a task on another's behalf without implying that the person is owned, including the table-waiters at the wedding and even civil authority as God's agent for good.Jhn 2:9Rom 13:4
οἰκέτηςan οἰκέτης is specifically a household slave, narrowing the setting to the home; δοῦλος is the general word for an owned person in any setting.
Carries the great theological self-title: a believer, prophet, or apostle calls himself the slave of God or of Christ. This word, not the household-servant word, is the one used to name belonging wholly to the Lord.Rom 1:1Jas 1:1Rev 1:1Luk 1:38
Names a person's whole legal status: slave as opposed to free, or to son, or to lord. It marks where someone stands in the order of things, not merely the work they do.Gal 3:28Jhn 8:35Gal 4:71Co 12:13
Is the stock figure of Jesus' parables, where a master entrusts his slaves with work, money, or a vineyard and then comes to settle accounts. The word stands in for the disciple answerable to God.Mat 25:21Mat 18:23Luk 12:37Mrk 12:2
Both
Both name a person who is owned and bound to serve a master, not a free hired worker. Either word can describe the ordinary servant of a master who gives orders and is owed obedience.Mat 8:91Pe 2:18
Pictures the slave inside a particular master's house: one of the staff under a single roof, owned by and answerable to the head of that home. The word frames servanthood as a domestic, household tie rather than a status in the wider world.Act 10:71Pe 2:18Rom 14:4
Underlines that such a servant belongs to one household and answers to that one master, so he cannot be split between two. The point of the word is the single house he is bound to.Luk 16:13Rom 14:4
θεράπωνθεράπων marks honored, willing attendance, used of Moses as God's trusted servant; it carries dignity without the note of being owned that δοῦλος always keeps.
Marks a person who is owned and bound, with no will of his own apart from the master who can buy, sell, command, punish, or free him. The whole picture is one of belonging to another, not of the dignity of the service.Mat 18:271Co 7:21Jhn 8:34
Used freely for the lowest social rank, the bottom of the household where a slave is contrasted with the free or with the master. It carries the sting of servitude that the gospel then turns upside down.Gal 3:28Mat 20:27Jhn 13:16
Stretches to a relationship of total ownership by God or Christ that a believer wears as a badge: the writer introduces himself as someone wholly possessed by his Lord, body and will.Rom 1:1Jas 1:1Rev 1:1
Both
Both name a person who serves God within God's household, and both can become titles of honor for his faithful servants. Strikingly, the very Moses who is the honored attendant in Hebrews is elsewhere called God's bondservant, so the two words can land on the same man.Rev 15:3Heb 3:5
Pictures a trusted, honored attendant rather than an owned slave. The single use describes Moses serving in God's whole house, and the word lends him standing and nearness to the one he serves, not the lowliness of a bought man.Heb 3:5
ὑπηρέτηςan ὑπηρέτης is a subordinate who acts under another's direction without saying anything about legal status; a δοῦλος is owned, while an ὑπηρέτης may be free.
A slave is OWNED by a master, body and labor belonging to another. The word frames a relationship of possession, where the slave answers wholly to the one who holds him and has no standing of his own.Mat 8:9Mat 18:27Jhn 8:34
It becomes the great picture of belonging in the gospel, both for bondage to sin and for total devotion to God or Christ. Paul and others proudly call themselves a slave of God, claiming a master worth being owned by.Rom 1:1Rom 6:17Php 1:1Rev 1:1
It is set in deliberate contrast with what is greater: a slave is not above his master, the lowest place at table, the one who must take the bottom rung to be first.Mat 20:27Jhn 13:16Jhn 15:15
Both
Both words name people who serve a household or institution, and they can stand side by side in the same scene: at the high priest's house the owned slaves and the hired officers warm themselves at the same fire, both attending the same masters.Jhn 18:18
This word names an attendant who carries out duties for someone in authority, without the idea of being owned. It is the standing role of the temple police and the chief priests' officers, the men sent to seize Jesus and who struck and guarded him.Jhn 7:32Jhn 18:3Jhn 18:22Jhn 19:6
It also covers the court bailiff who jails a man, the synagogue attendant who handles the scroll, and the temple guards reporting to the council. The focus is the official task assigned, not a household or a master who owns the person.Mat 5:25Luk 4:20Act 5:22
Lifted up, it describes those who serve as assistants of the word and ministers of Christ, the trusted helper entrusted with a commission rather than a piece of property.Luk 1:2Act 26:161Co 4:1
μισθωτόςa μισθωτός is a free worker hired for wages who can walk away; this is the exact opposite of a δοῦλος, who is owned and unpaid.
A slave is owned, not paid. The master holds the person, not merely buys his labor by the hour, so he can be sold, given away, or set free as property, and he works without wages.Mat 18:27Luk 17:7
It readily turns into a picture of total belonging to someone, so it names the believer who belongs wholly to God or to Christ, and even the person enslaved to sin.Rom 1:1Jhn 8:34
Both
Both work under someone else and do that person's business rather than their own. A slave answers to his master and a hired hand to his employer, and the same scene can hold both kinds of worker side by side.Luk 17:7Mrk 1:20
A hired worker is paid for the job and is free to walk away. His tie to the work is only as deep as the wage, so when danger comes he abandons the sheep, because they are not his and he has no stake in them.Jhn 10:12Jhn 10:13
σύνδουλοςa σύνδουλος is a fellow slave, the same status as δοῦλος but viewed alongside others who share the same master, which is why it can place angels and people on one level as fellow slaves of God.
Names a slave purely by his bond to a master, with no reference to other slaves. The whole focus is the one who owns him and the obedience he owes upward.Mat 8:9Luk 17:7
Carries the believer's standing before God or Christ as a willing slave, a self-designation the apostles wear with honor.Rom 1:1Php 1:1Rev 1:1
Describes being owned and ruled by something other than a person, such as sin, where there is no master-and-fellow-slave household at all.Jhn 8:34Rom 6:17
Both
Both name a person owned by a master; in the one parable the king's slave and the man he throttles are each slaves of the same lord, the second simply seen as his peer.Mat 18:28
Names a slave by his relationship to the OTHER slaves of the same master, not to the master himself. The point is the peer standing among equals who serve one owner.Mat 18:29Mat 18:33
Exposes the wrong of mistreating an equal: the failure is precisely that the victim was a fellow slave, owed the same mercy the offender had just received.Mat 18:31Mat 24:49
Levels rank between servants of God: an angel refuses worship by calling himself a fellow servant, and Paul gives the title to his trusted co-workers.Rev 19:10Col 1:7
δοῦλος names a person's legal standing, not a job. A slave is owned, bought at a price, and belongs to whoever holds him, which is why it is the word that gets set opposite "free" whenever the New Testament lists the categories people fall into.1Co 7:23Gal 3:28Col 3:11
Because it says "owned," δοῦλος becomes the standard picture of moral bondage: the person who keeps sinning is not merely misbehaving but held, unable to walk away from what has hold of him.Jhn 8:34Rom 6:162Pe 2:19
δοῦλος marks the bottom of the ranking, so Jesus uses it to overturn ambition: whoever wants to be first must take the lowest place, and no slave is above the one who owns him.Mat 20:27Mrk 10:44Jhn 13:16
It is the title New Testament writers give themselves at the head of a letter, a way of naming whose they are before saying anything else. οἰκονόμος is never used to sign a name that way.Rom 1:1Jas 1:1Jud 1:1
Both
Both stand under a master and both are called in to answer for what they did with what he left them, so either word can carry a parable about accountability.Mat 25:19Luk 19:15Luk 16:11Co 4:2
The two can describe the very same person. In one parable Jesus asks who the faithful and wise manager is, then answers by calling that same figure the slave whom the master finds at work.Luk 12:42Luk 12:43
Both become pictures of the Christian's place before God, one stressing that we belong to him and one stressing that what we handle is his and not ours.1Pe 2:16Rev 22:31Pe 4:101Co 4:1
οἰκονόμος names a post rather than a standing: the man put in charge of a household's property and staff, handing out the food allowance at the right time and acting with the owner's authority while the owner is away.Luk 12:42Gal 4:2
A post can be taken away, which no legal status can. When the manager is accused of wasting his master's goods he faces losing the job itself and asks what he will do next.Luk 16:1Luk 16:3
The single quality the word demands is trustworthiness with what belongs to someone else, so it is the natural word for a church leader handling God's household and for believers handling gifts they did not generate.1Co 4:2Tit 1:71Pe 4:10
The manager need not be owned at all. Erastus holds the city's purse as a man of standing in Corinth, which is a role a slave could fill but plenty of free men held too.Rom 16:23
This is the word believers pick up for themselves before God, so it turns from a social label into a title of honor: Paul, James and John open by naming themselves God's slave, and Mary answers the angel the same way.Rom 1:1Jas 1:1Rev 1:1Luk 1:38
It is the general status word for anyone who is owned, and it covers women as well as men, which is why it can be paired with "free" as one half of a standing division of society.Gal 3:28Rev 6:15Luk 1:38
Only this word is used to say what owns a person on the inside: a life can be enslaved to sin, to corruption, or to God's righteousness.Jhn 8:34Rom 6:16Rom 6:202Pe 2:19
In the parables it names a worker trusted with real responsibility, handed the master's money or put over the rest of the staff and answerable for the results.Mat 24:45Mat 25:14Mat 25:21Luk 19:13
It is the word the letters use when they address owned workers directly about how to live under a master, so it carries the working ethics of the household.Eph 6:5Col 3:22Tit 2:9
Both
Both name a person who is owned rather than hired, working in one household under one master, and the same parable sets them side by side: the slave left in charge starts beating the serving girls, and being owned did not make the two ranks equal.Luk 12:45
It always names a woman, and usually a young one, so it identifies a person by being the household's serving girl rather than by name.Mat 26:69Mrk 14:69Act 12:13
The people it names stand at the edge of a scene, at a gate or by a courtyard fire, doing the errands nobody records, and yet what they say turns the story: a girl's question breaks Peter, and a girl at the door is the first to know he has been released.Mrk 14:66Luk 22:56Jhn 18:17Act 12:13
It marks a woman whose body and voice earn money for the people who own her, as with the girl at Philippi whose fortune telling was her owners' income.Act 16:16
Because it names a mother, it carries Paul's picture of the two covenants, where the mother's standing settles the child's: the slave woman's son is sent away and Christians belong to the free woman instead.Gal 4:22Gal 4:23Gal 4:30Gal 4:31
Names a person as owned property: the lowest rung of the household, defined by belonging to a master and set opposite the free person.Gal 3:28Col 3:11Eph 6:5
Becomes the believer's glad self-title of total belonging to God or Christ, worn as a badge of honor by the apostles.Rom 1:1Php 1:1Jas 1:1
Stretches into a metaphor of being owned by a power, so a person can be enslaved to sin or bound over to righteousness.Jhn 8:34Rom 6:17Rom 6:19
Both
Both name a servant who works under a master and does his bidding within a household.Luk 12:45Jhn 4:51
Both can denote the attendants of a king or ruler who carry out his orders.Mat 18:23Mat 22:3Mat 14:2
Can mean simply a child or boy by age, with no servitude in view at all.Mat 2:16Mat 17:18Luk 2:43Act 20:12
Carries the honorable Servant of the LORD, the one God chose and delights in, applied to Jesus, David, and Israel.Mat 12:18Act 3:13Act 4:27Luk 1:54Luk 1:69
Can name a cherished household servant, close enough to the family that his master pleads for his healing, blending the senses of boy and servant.Mat 8:6Mat 8:8Luk 7:7
doulos in the other biblical languages
עֶבֶדHebrew“servant/slave”עֶבֶד is the Hebrew word δοῦλος most often translates in the Greek Old Testament; it likewise spans an owned slave and the honored "servant of the LORD," and it is the source of the title's covenant dignity.
Stresses unfree, owned status in a Greco-Roman slave economy: the slave set against the free person and against the son, with no rights of his own.Jhn 8:35Gal 4:71Co 7:21
Both
The usual Greek rendering of this Hebrew word, including the devotional "servant of God": a person wholly bound to a master, claimed as the honored self-designation of God's people and their leaders.Psa 113:1Rom 1:1
Ranges past mere ownership to the honored royal official, and is the abundant covenant title for the worshippers and chosen figures God calls "my servant".Isa 42:12Sa 7:5
שָׁרַתHebrew“to minister”שָׁרַת describes ministering or attending in honored, often priestly service; unlike δοῦλος it names willing, dignified service and never implies being owned.
Marks a person as owned property who belongs to a master and has no will of his own, the opposite of a free man.1Co 7:211Co 7:22Gal 3:28
Names the lowest social rank, the one who must obey and can be beaten, sold, or commanded, set under the household head.Mat 8:9Mat 18:27Luk 12:47
Used by believers as a title of total surrender to God or Christ, glad bondage to a new owner rather than a paid job.Rom 1:1Php 1:1Jas 1:1
Describes spiritual bondage, a person enslaved to sin or to corruption and so unable to break free on his own.Jhn 8:34Rom 6:172Pe 2:19
Both
Both are commonly rendered "serve" or "servant" in English, even though one carries the idea of being owned and the other the idea of honored attendance.Jos 1:1Mat 10:24
Both can describe a person who waits on and obeys a superior, carrying out that master's commands rather than acting on his own.Gen 40:4Mat 13:27
Both are used for devoted service rendered to God himself, whether ministering in his worship or belonging wholly to him.Jol 1:9Rev 7:3
Carries legal ownership. The person is property, bought at a price, and is defined by contrast with the free person and with the son who inherits.1Co 7:23Gal 3:28Jhn 8:35Gal 4:7
Belongs to an everyday working economy, so it names field hands and household staff who are sent on errands, rewarded, beaten, or thrown out at a master's word.Luk 17:7Luk 12:47Mat 25:30Eph 6:5
Stretches into a picture of being owned by a power rather than by a person, so someone can be called a slave of sin or of decay.Jhn 8:34Rom 6:172Pe 2:19
Both
Both name a person who belongs to a named master and answers to him, and the Greek word is the standard equivalent that stands where the Aramaic one does when Ezra and Daniel are read in Greek.Dan 2:7Mat 24:45
Each becomes a title of honor in the phrase "servant of God", used both by outsiders describing the faithful and by the faithful naming themselves.Dan 6:20Ezr 5:11Act 16:17Rom 1:1
Belongs to the language of the Persian and Babylonian court, where a province's leading men and a king's own advisers call themselves his servants in official speech, with no suggestion that anyone owns them.Ezr 4:11Dan 2:4Dan 2:7
Never stands alone as a label for a class of people. All seven appearances say whose servant the person is, and not one of them describes someone held as property or set opposite a free person, so English "slave" overreaches here.Ezr 5:11Dan 3:26Dan 3:28
What scholars say about doulos
The lexical question is now firmly settled: δοῦλος means a slave in the strict ancient sense of a person owned by another, not a hired "servant." BDAG (3rd ed., 260) defines it as "male slave, as an entity in a socioeconomic context" and notes that the "servant" rendering is largely confined to Bible translation; Louw-Nida (87.76) places it in the status domain of ownership, deliberately apart from διάκονος, which sits in the domain of commissioned service. Behind the word lie two backgrounds that the New Testament holds together. The first is the brutal reality of Greco-Roman slavery, reconstructed by Bradley, Glancy, Harrill, and Patterson, where slaves were legally property and roughly a fifth of Italy's population. The second is the Greek Old Testament, where δοῦλος renders Hebrew עֶבֶד hundreds of times and turns total ownership by God into covenant honor (Rengstorf, TDNT 2:261-80; Byron). Murray Harris's monograph reads the New Testament's δοῦλος as a positive metaphor of total devotion to Christ. The live debates concern not the meaning but the resonance: whether Paul's "slave of Christ" is heard mainly against the Old Testament servant tradition (Cranfield, Dunn, Fitzmyer, Byron) or against the high-status managerial slave of the Roman world (Dale Martin) or as a deliberate embrace of dishonor (Glancy, Harrill); and how to translate the word into English without either softening it to "servant" or collapsing it into modern associations.
