Servant
Servant in the UPDV runs along two registers that the same vocabulary keeps welding together. A "slave" (the dominant rendering of the underlying Hebrew and Greek words) is at once a household figure with concrete legal standing and a theological figure for whom the question is never whether one belongs to a master, but to which master. Pharaoh's overseers and Israel's jubilee, Hagar returning to Sarah and Onesimus returning to Philemon, the slave of sin and the slave of God all share the same lexicon. The page below traces that lexicon as the UPDV preserves it.
Slaves and the Mosaic Ordinance
The first body of legislation Moses receives after the Decalogue is the law of the slave. Exodus opens its ordinances with the purchase clause: "If you buy a Hebrew slave, six years he will serve: and in the seventh he will go out free for nothing" (Ex 21:2). The wife and children given by the master remain with him, but a slave who refuses to leave by reason of love is fixed in service by a public ritual: "his master will bring him to the gods, and will bring him to the door, or to the door-post; and his master will bore his ear through with an awl; and he will serve him forever" (Ex 21:6). A daughter sold "to be a slave...will not go out as the male slaves do" (Ex 21:7), and the master who refuses her food, raiment, and marriage duty must let her go for nothing (Ex 21:11).
Deuteronomy reframes the same six-and-seventh pattern around the master's memory and provisioning. "If your brother, a Hebrew man, or a Hebrew woman, is sold to you, and serves you six years; then in the seventh year you will let him go free from you" (De 15:12). The release is not empty: "you will furnish him liberally out of your flock, and out of your threshing-floor, and out of your wine press" (De 15:14). The reason is autobiographical: "you will remember that you were a slave in the land of Egypt, and Yahweh your God redeemed you" (De 15:15). The awl-and-door rite from Exodus is repeated for the slave who chooses to stay (De 15:17).
Leviticus 25 lifts the framework into the jubilee. A Hebrew brother sold by poverty is not to be treated as a slave at all: "As a hired worker, and as a sojourner, he will be with you; he will serve with you to the year of jubilee" (Le 25:40). The theological ground is ownership: "For they are my slaves, whom I brought forth out of the land of Egypt: they will not be sold as a slave" (Le 25:42). Foreign-bought slaves remain a possession (Le 25:44-46), but no Israelite "will rule over him with rigor" (Le 25:43). The jubilee proclamation itself is an emancipation: "you⁺ will hallow the fiftieth year, and proclaim liberty throughout the land to all its inhabitants" (Le 25:10).
Bondservants in the Households of the Patriarchs
Patriarchal narrative shows the law's vocabulary already in motion. Hagar, fled from Sarah, is sent back by an angel: "Return to your mistress, and submit yourself under her hands" (Ge 16:9). When Sarah later expels her, the slave register sharpens: "Cast out this slave and her son. For the son of this slave will not be heir with my son, even with Isaac" (Ge 21:10). Joseph's land policy in Egypt makes a free people voluntarily enter slavery for grain: "You have saved our lives: let us find favor in the sight of my lord, and we will be Pharaoh's slaves" (Ge 47:25). Jacob's blessing of Issachar uses the same language as economic verdict: "And he bowed his shoulder to bear, And became slave labor" (Ge 49:15).
Mosaic law also legislates for the female slave whose status is contested: "And whoever plows a woman, who is a female slave, betrothed to a husband, and not at all redeemed, nor freedom given her; they will be punished; they will not be put to death, because she was not free" (Le 19:20).
The Taskmasters of Egypt
The pattern flips when Israel itself is the slave. Pharaoh's policy in Exodus is institutional: "Therefore they set over them slave masters to afflict them with their burdens. And they built for Pharaoh store-cities, Pithom and Raamses" (Ex 1:11). When the work-quota is increased, the chain of command is named: "the same day Pharaoh commanded the taskmasters of the people, and their officers" (Ex 5:6), and "the taskmasters of the people went out, and their officers, and they spoke to the people, saying, Thus says Pharaoh, I will not give you⁺ straw" (Ex 5:10). The Deuteronomic command to remember Egyptian slavery is built directly on top of this scene.
National Bondage and Emancipation
The slavery vocabulary scales up to nations. Solomon "raised slave labor" from the surviving Canaanites "to this day" (1Ki 9:21). Esther speaks for her people facing extermination: "for we have been sold, I and my people, to be destroyed, to be slain, and to perish. But if we had been sold for male slaves and female slaves, I would have held my peace" (Es 7:4). Isaiah twice frames Israel's exile as a sale that Yahweh did not need to make: "Look, for your⁺ iniquities you⁺ were sold, and for your⁺ transgressions your⁺ mother was put away" (Is 50:1); "You⁺ were sold for nothing; and you⁺ will be redeemed without silver" (Is 52:3).
Emancipation runs through the Old Testament alongside it. Cyrus's edict ends Babylonian exile: "All the kingdoms of the earth has Yahweh, the God of heaven, given me; and he has charged me to build him a house in Jerusalem...Whoever there is among you⁺ of all his people, Yahweh his God be with him, and let him go up" (2Ch 36:23; cf. Ezr 1:3). Jeremiah preserves a covenant of release: Zedekiah "made a covenant with all the people who were at Jerusalem, to proclaim liberty to them" (Je 34:8), "that every man should let his male slave, and every man his female slave, who is a male Hebrew or a female Hebrew, go free" (Je 34:9). Isaiah's servant of Yahweh inherits the jubilee oracle: "The Spirit of the Sovereign Yahweh is on me; because Yahweh has anointed me to preach good news to the meek; he has sent me to bind up the brokenhearted, to proclaim liberty to the captives, and the opening [of the prison] to those who are bound" (Is 61:1). Luke records Jesus reading from the same oracle: "He has sent me to proclaim release to the captives, And recovering of sight to the blind, To set at liberty those who are bruised" (Lu 4:18).
The Maccabean record uses the same lexicon for its own war of independence. The yoke of Greek rulers is the recurring image: the Romans, the Jewish embassy notes, were sought "that they might take off from them the yoke of the Greeks, for they saw that they oppressed the kingdom of Israel with servitude" (1Ma 8:18). The Senate writes Demetrius, "Why have you made your yoke heavy on our friends and allies, the Jews?" (1Ma 8:31). Simon's diplomacy and the providence of his house culminate in liberty granted and recorded: Simon "chose men and sent to King Demetrius, to the end that he should grant liberty to the land" (1Ma 13:34); "In the year one hundred and seventy the yoke of the nations was taken off from Israel" (1Ma 13:41); "they decreed him liberty, and registered it in tablets of bronze, and set it on pillars in Mount Zion" (1Ma 14:26); "let Jerusalem be holy and free" (1Ma 15:7).
Saints as Slaves of God
The most surprising place the vocabulary lands is on the saints themselves. Elijah at Carmel prays, "O Yahweh, the God of Abraham, of Isaac, and of Israel, let it be known this day that you are God in Israel, and that I am your slave, and that I have done all these things at your word" (1Ki 18:36). The Chronicler titles Moses identically: "according to all that Moses the slave of God had commanded" (1Ch 6:49). The returning exiles describe themselves to the Persian governor: "We are the slaves of the God of heaven and earth, and are building the house" (Ezr 5:11). Daniel's three companions are summoned out of the furnace as "you⁺ slaves of the Most High God" (Da 3:26), and Darius hails Daniel from the lions' den as "slave of the living God" (Da 6:20).
The same title is taken up in the Greek. Paul to the Romans: "For God is my witness, whom I serve in my spirit in the good news of his Son, how I unceasingly remember you⁺" (Ro 1:9). Paul again to Timothy: "I thank God, whom I serve from my forefathers in a pure conscience" (2Ti 1:3). James: "James, a slave of God and of the Lord Jesus Christ, to the twelve tribes which are of the Dispersion: Greetings" (Jas 1:1). Peter: "as free, and not using your⁺ freedom for a cloak of wickedness, but as slaves of God" (1Pe 2:16). Sirach gives the same usage in wisdom register: "Those who are holy servants, serve her, And God is with those who desire her" (Sir 4:14).
Slaves of Sin, Slaves of Righteousness
Jesus introduces the spiritual axis directly: "Everyone who commits sin is the slave of sin" (Jn 8:34), and "the truth will make you⁺ free" (Jn 8:32). Paul develops both halves at length. "Don't you⁺ know, that to whom you⁺ present yourselves [as] slaves to obedience, his slaves you⁺ are whom you⁺ obey; whether of sin to death, or of obedience to righteousness?" (Ro 6:16). The slave-changes-master logic is the engine: "thanks be to God, that, whereas you⁺ were slaves of sin, you⁺ became obedient from the heart to that form of teaching to which you⁺ were delivered; and being made free from sin, you⁺ were made a slave to righteousness" (Ro 6:17-18). The same turn is summarized: "now being made slaves to God, you⁺ have your⁺ fruit to sanctification, and the end eternal life" (Ro 6:22).
The bondage side runs deep. "I am carnal, sold under sin" (Ro 7:14). Israel's idolatry is described as a self-sale: Ahab "sold yourself to do that which is evil in the sight of Yahweh" (1Ki 21:20); the northern kingdom "sold themselves to do that which was evil" (2Ki 17:17). Wisdom catches the wicked in the same net: "His own iniquities will take the wicked, And he will be held with the cords of his sin" (Pr 5:22). Peter spells out the false gospel of liberty: those who promise freedom "themselves are slaves of corruption; for to whom a man is overcome, to this one he has been made a slave" (2Pe 2:19), and Paul names the snare of the devil "having been taken captive by him to his will" (2Ti 2:26).
The release side is just as concrete. "The law of the Spirit of life in Christ Jesus made you free from the law of sin and of death" (Ro 8:2); "the creation itself also will be delivered from the slavery of corruption into the liberty of the glory of the children of God" (Ro 8:21). "Now the Lord is the Spirit: and where the Spirit of the Lord is, [there] is liberty" (2Co 3:17). Galatians presses the contrast through the Hagar-Sarah allegory: "we are not children of a slave woman, but of the free woman" (Ga 4:31).
The Author of Diognetus on Freedom from Idols
The Epistle to Diognetus picks up the slave-to-idol vocabulary directly. Defending Christians from the charge of irreverence toward the gods of the city, the writer breaks off the argument: "In regard then, to the freedom of Christians from being enslaved to such gods, I would have many other things to say; but if, to any, these do not seem sufficient, I count it superfluous to say more" (Gr 2:10). The phrase rides the same axis as Paul's "slaves to obedience" / "slave to righteousness": worship is service, idol-worship is enslavement, and what is at stake in Christian refusal of the city's gods is not impiety but emancipation.
The Limits of Christian Liberty
Freedom in Christ in the New Testament is constrained by two further rules. The first is non-self-bondage: "All things are lawful for me; but not all things are expedient. All things are lawful for me; but I will not be brought under the power of any" (1Co 6:12). The second is voluntary servanthood for the sake of others: "though I was free from all [men], I became a slave to all, that I might gain the more" (1Co 9:19). The misuse of liberty is a stumbling block: "But take heed lest by any means this liberty of yours⁺ become a stumbling block to the weak" (1Co 8:9). And freedom is not license: "you⁺, brothers, were called for freedom; only [do] not [use] your⁺ freedom for an occasion to the flesh, but through love serve as slaves to one another" (Ga 5:13). Paul polemicizes against false brothers in the same vocabulary: they "came in secretly to spy out our liberty which we have in Christ Jesus, that they might bring us into slavery" (Ga 2:4). Peter joins the chorus: "as free, and not using your⁺ freedom for a cloak of wickedness, but as slaves of God" (1Pe 2:16).
The same tension appears in Sirach's wisdom: "A slave who deals wisely, love as your own soul; Do not withhold freedom from him" (Sir 7:21); "Set your servant to work, and he will seek rest, Leave his hands idle, and he will seek liberty" (Sir 33:25). The proverbial freedom of a "headstrong daughter" is named as a danger: "Upon a headstrong daughter keep watch, Lest, finding liberty, she uses it for herself" (Sir 26:10).
Master and Slave in the Christian Household
The household codes preserve the master-slave structure but place both parties under one Lord. Paul to the Ephesians: "Slaves, be obedient to those who according to the flesh are your⁺ masters, with fear and trembling, in singleness of your⁺ heart, as to Christ; not in the way of eyeservice, as men-pleasers; but as slaves of Christ, doing the will of God from the soul" (Eph 6:5-6). The reverse is named in the same breath: "And, you⁺ masters, do the same things to them, and forbear threatening: knowing that he who is both their Master and yours⁺ is in heaven, and there is no favoritism with him" (Eph 6:9). Colossians repeats the move: "you⁺ serve as slaves to the Lord Christ. For he who does wrong will receive again for the wrong that he has done: and there is no favoritism" (Col 3:24-25). The pastoral letters address both believing and unbelieving households: "Let as many as are slaves under the yoke count their own masters worthy of all honor, that the name of God and the doctrine not be blasphemed. And those who have believing masters, don't let them despise them, because they are brothers; but let them serve as better slaves" (1Ti 6:1-2).
The principle of equal status comes through unsubtly: "Were you called being a slave? Do not care about it: but, if you can become free, use rather [the opportunity to be free]" (1Co 7:21); "There can be neither Jew nor Greek, there can be neither slave nor free, there can be no male and female; for you⁺ are all one in Christ Jesus" (Ga 3:28).
The clearest test case is Onesimus. Paul sends the runaway slave back to Philemon "no longer as a slave, but more than a slave, a brother beloved, especially to me, but how much rather to you, both in the flesh and in the Lord" (Phm 1:16). The relationship is not legally dissolved on the page — Paul instead makes himself the guarantor: "if he has wronged you at all, or owes [you] anything, put that to my account; I Paul write it with my own hand, I will repay it" (Phm 1:18-19) — but the social register has been rewritten end-to-end. Paul closes by trusting Philemon to "do even beyond what I say" (Phm 1:21).
The Faithful and Unfaithful Slave
The parable of the pounds turns the vocabulary into character study. Ten slaves are entrusted with a mina apiece. The faithful slave receives "Well done, you good slave: because you were found faithful in a very little, have authority over ten cities" (Lu 19:17). The slave who hides his mina is told, "Out of your own mouth I will judge you, you wicked slave" (Lu 19:22).
In a one-line catechesis on duty, Jesus puts the unprofitable-slave principle in its bluntest form:
"Even so you⁺ also, when you⁺ will have done all the things that are commanded you⁺, say, We are unprofitable slaves; we have done that which it was our duty to do" (Lu 17:10).
The setup before it is a domestic scene: a master "having a slave plowing or shepherding" does not invite him to table when he comes in from the field but tells him to gird up and serve his lord first (Lu 17:7-8). The household vocabulary holds, and the saint-as-slave-of-God lives inside it.
