ἐπίσκοπος

There is another unexpected English word that descends directly from Greek.

The word is bishop.

Like “priest” (which we treated in the Presbyteros entry), “bishop” descends through a chain of contraction and linguistic descent. The Old English form was biscop. The Latin was episcopus. The Greek was episkopos. The chain is unbroken: bishop = episcopus = episkopos. The English word for the highest-ranking clergy in the Catholic, Anglican, and Orthodox traditions is, etymologically, the New Testament word for overseer.

This matters theologically. The medieval and modern understandings of “bishop” have been shaped by centuries of development in which the office acquired distinctive features that the New Testament word episkopos did not originally carry. The bishop became a successor of the apostles in a specific sacramental sense, with claims of unbroken hands-on-heads transmission from the apostolic era. The bishop became the holder of a separate order distinct from priest and deacon, with exclusive authority to ordain. The bishop became identified with a particular diocese — a geographic territory containing multiple parishes under his oversight. The bishop became, in some traditions, the visible head of a national or regional church, with substantial administrative power and, in earlier centuries, political authority as a feudal lord.

But the New Testament episkopos is a different and simpler thing. The word means “overseer” — one charged with watching over, supervising, taking responsibility for a defined sphere. In the New Testament’s actual usage, the episkopos is the leader of a local Christian assembly, charged with oversight of doctrine and life among the believers gathered there. The episkopos is normally also called presbyteros, because the same office is being viewed from different angles: presbyteros names the person (an elder, a respected senior member entrusted with leadership), and episkopos names the function (the oversight the elder exercises). In the New Testament, these are not yet two separate offices.

This is the entry on episkopos. The entry’s task is to recover what the New Testament word actually meant, to address the historical development of the threefold ministry (bishop, presbyter, deacon) that emerged after the apostolic period, and to lay out the Lutheran position on episcopal polity — which has varied considerably across the Lutheran tradition while maintaining a consistent understanding of what the office is and is not.

The Word

ἐπίσκοπος (episkopos), pronounced eh-PEES-koh-pos. A masculine noun. A compound of epi (ἐπί, “over, upon”) and skopos (σκοπός, “one who watches, a watcher”), built on the verb skopeō (σκοπέω, “to look at, to watch, to observe carefully”). The literal etymology gives “one who watches over.” The family is theologically loaded:

• skopeō (verb, to look at, watch).
• skopos (noun, one who watches; also: a goal, a target — what one is looking at).
• episkopos (noun, overseer, supervisor).
• episkopeō (verb, to oversee, exercise oversight).
• episkopē (noun, oversight; office of oversight; visitation, also in the eschatological sense of God’s coming to visit His people).

The English derivative chain is striking and worth knowing. Episkopos in Greek became episcopus in Latin (direct transliteration). Episcopus contracted in Old English to biscop (with the initial vowel dropped, as often happens in Germanic borrowing of Latin words). Biscop became Middle English bischop and then modern English bishop. Along the way, every linguistic descendant preserved the basic root meaning of “overseer” even when the historical office had developed distinctive features the original Greek word did not carry.

The classical Greek background is essential. Episkopos was a standard term in Greek civic and military life for various kinds of supervisors and overseers:

• Athenian episkopoi were officials sent to supervise allied or dependent cities — a function not unlike a Roman governor in later periods.
• Military episkopoi served as supervisors of specific tasks or units.
• Temple episkopoi were cultic supervisors charged with the oversight of religious practice and ritual purity.
• Commercial episkopoi served as inspectors of weights, measures, and trade goods.
• The word also appears in philosophical contexts for the supervisor of a school or a moral tutor.

The general sense across these usages is consistent: the episkopos is one charged with oversight of a defined sphere. The function is supervision, inspection, responsibility, watching-over. The word implies authority (the episkopos has the right to oversee) but also accountability (the episkopos is responsible for what he oversees). It is not a passive title; it names an active function.

The Septuagint background is more limited than for some other New Testament terms. The Greek translators used episkopos and its cognates for various Hebrew supervisory terms — paqid (officer, overseer), shoter (officer), and others — without making episkopos a major theological term in the Old Testament. The word is present in the Septuagint but not centrally developed.

What is striking is that the New Testament uses episkopos sparingly but in important contexts. The word and its verbal cognates appear about ten times across the New Testament — far fewer than presbyteros (which appears about sixty times) or diakonos (which appears about thirty times). But the New Testament uses give the word a distinctive theological weight, particularly in the Pastoral Epistles’ detailed treatment of the qualifications for the office.

Range of Meaning

In its New Testament usage, episkopos and its cognates cover:

• The leader of a local Christian assembly, exercising oversight. The dominant technical-theological usage, particularly in the Pastoral Epistles.
• The function of oversight as exercised by elders (the verbal form episkopeō, used of what elders do; 1 Pet 5:2).
• Christ Himself as the chief Overseer of souls. 1 Peter 2:25.
• God’s gracious visitation of His people — episkopē in the broader sense of God’s “coming to look upon.” His people in mercy or judgment. Luke 19:44.
• The office of oversight as such — episkopē in 1 Tim 3:1 (“This saying is trustworthy: ‘If someone aspires to the office of overseer, he desires a good work.’”), referring to the office of overseer as a category.

The dominant theological usage is the first — the local Christian leader who exercises oversight. The entry focuses there, with attention to what oversight actually involves and to the relationship between episkopos and the developed concept of “bishop.”

Where You’ll Meet It

“From Miletus he sent a message to Ephesus, telling the elders of the church to come to him. … Watch out for yourselves and for all the flock of which the Holy Spirit has made you overseers, to shepherd the church of God that he obtained with the blood of his own Son.” (Acts 20:17, 28, NET)

Already cited in the Presbyteros entry. The same group of men — addressed as presbyteroi in verse 17 and as episkopoi in verse 28. The Holy Spirit “has made” them overseers; the office is the Spirit’s appointment, not a self-elected position. The function is care for the flock; the basis is Christ’s purchase of the church with His own blood. This verse is one of the foundational New Testament texts for the identity of presbyteros and episkopos and for understanding what oversight actually involves: care for the flock, on Christ’s authority, by the Spirit’s appointment.

“From Paul and Timothy, slaves of Christ Jesus, to all the saints in Christ Jesus who are in Philippi, with the overseers and deacons.” (Philippians 1:1, NET)

Paul’s salutation to the Philippian church. The structure is striking: he greets “all the saints in Christ Jesus” along with “the overseers and deacons.” Two groups are named alongside the saints: episkopoi and diakonoi. No separate presbyteroi are mentioned, which strongly suggests that the episkopoi of Philippians are the same people the elsewhere-mentioned presbyteroi would be. The Philippian church had a leadership structure consisting of overseers and deacons, but the overseers are not yet distinguished from elders as a separate order. The threefold ministry of the second century onward is not yet visible in Philippians.

“This saying is trustworthy: ‘If someone aspires to the office of overseer, he desires a good work.’ The overseer then must be above reproach, the husband of one wife, temperate, self-controlled, respectable, hospitable, an able teacher, not a drunkard, not violent, but gentle, not contentious, free from the love of money. He must manage his own household well and keep his children in control without losing his dignity. But if someone does not know how to manage his own household, how will he care for the church of God? He must not be a recent convert, or he may become arrogant and fall into the punishment that the devil will exact. And he must be well thought of by those outside the faith, so that he may not fall into disgrace and be caught by the devil’s trap.” (1 Timothy 3:1–7, NET)

The fullest New Testament treatment of the qualifications for the office. Paul opens with “the office of overseer” — episkopē — naming the office itself by the abstract noun. He lists the qualifications across multiple dimensions: character (above reproach, sober-minded, self-controlled, respectable), interpersonal (hospitable, gentle, not quarrelsome), competence (able to teach, manages household well), maturity (not a recent convert), and reputation (well thought of by outsiders). The qualifications are demanding but not impossible; the episkopos is expected to be a mature, faithful, capable believer — not a perfect saint, but a man whose character commends the gospel he proclaims and the office he holds.

Notable in this list: “an able teacher” (didaktikon). The episkopos is a teacher. Oversight includes the teaching ministry. The man who cannot teach the gospel and the apostolic deposit cannot oversee an assembly in the New Testament sense. The qualifications also include the family dimension: managing his own household well, keeping his children submissive. The household life is part of the qualification because the office of oversight in the church is consistent with — and develops out of — the oversight of one’s own household.

“The reason I left you in Crete was to set in order the remaining matters and to appoint elders in every town, as I directed you. An elder must be blameless, the husband of one wife, with faithful children who cannot be charged with dissipation or rebellion. For the overseer must be blameless as one entrusted with God’s work, not arrogant, not prone to anger, not a drunkard, not violent, not greedy for gain. Instead he must be hospitable, devoted to what is good, sensible, upright, devout, and self-controlled. He must hold firmly to the faithful message as it has been taught, so that he will be able to give exhortation in such healthy teaching and correct those who speak against it.” (Titus 1:5–9, NET)

Already cited in the Presbyteros entry. The Titus passage parallels 1 Timothy 3 closely, with the same shift from “elder” (verse 5) to “overseer” (verse 7) within the qualification passage. The shift confirms that Paul is using the terms interchangeably for the same office.

What is distinctive in Titus is the closing emphasis: the episkopos must “he must hold firmly to the faithful message as it has been taught, so that he will be able to give exhortation in such healthy teaching and correct those who speak against it.” Oversight includes the doctrinal dimension explicitly — instruction in sound doctrine, refutation of error. The episkopos is not merely an administrator; he is a guardian of the gospel deposit, charged with teaching the truth and answering those who contradict it.

“Give a shepherd’s care to God’s flock among you, exercising oversight not merely as a duty but willingly under God’s direction, not for shameful profit but eagerly. And do not lord it over those entrusted to you, but be examples to the flock.” (1 Peter 5:2–3, NET)

The verbal form episkopountes — “exercising oversight.” Peter to the elders. The instructions are revealing: oversight is exercised willingly (not under compulsion), eagerly (not for shameful gain), and as examples (not domineering). The triple negation specifies what oversight is not: it is not coerced labor, it is not motivated by money, it is not lordship-over. The triple positive specifies what oversight is: it is voluntary service, motivated by love of Christ and His people, and exemplary in character. This verse is one of the strongest New Testament texts against the medieval lord-bishop model that Luther’s Reformation would later reject.

“For you were going astray like sheep but now you have turned back to the shepherd and guardian of your souls.” (1 Peter 2:25, NET)

The Christological climax. Christ Himself is named poimēn kai episkopos tōn psychōn humōn — “the shepherd and guardian of your souls.” The two terms appear together: Christ is both poimēn (shepherd) and episkopos (overseer). The pastoral oversight exercised by human pastors is derivative; the chief Pastor and chief Overseer is Christ Himself. The human office serves the divine office. The pastor watches over the flock on behalf of the One who is the true Watcher.

What Confessional Lutherans Hear

We hear episkopos with three emphases.

First, episkopos in the New Testament is the function side of the same office Presbyteros treated under presbyteros. The pastor’s work involves oversight — of doctrine, of life, of the assembly’s faithfulness to Christ. The Lutheran tradition has held that the New Testament office is one, named by multiple titles that emphasize different dimensions:

• Presbyteros names the person — the elder, the respected senior member entrusted with leadership.
• Episkopos names the function — the oversight that the elder exercises.
• Poimēn names the relationship — the shepherd who tends the flock.
• Diakonos in its broad sense (with which the Diakonos entry will deal) names the posture — service to Christ and the church.

These are not yet four separate offices in the New Testament. They are four ways of naming what one office does and is. The Lutheran reading of Acts 20:17, 28 is decisive: Paul calls for the elders (presbyteroi) and addresses them as overseers (episkopoi) charged with shepherding the flock. Same men. One office. Multiple terms.

This means the question of what the episkopos does is also the question of what the pastor does — the man Presbyteros addressed. The Lutheran pastor exercises oversight in the New Testament sense by:

• Watching over the doctrinal life of the assembly. Does the gospel get preached purely? Are heresies and errors named and refuted? Is the apostolic deposit faithfully transmitted? Titus 1:9 — the episkopos “be able to give exhortation in such healthy teaching and correct those who speak against it”
• Watching over the sacramental life of the assembly. Do the sacraments get administered rightly? Are the Word and the elements joined in the way Christ instituted? Are the members of the assembly properly prepared to receive the means of grace?
• Watching over the practical life of the assembly. Are the members walking faithfully in Christ? Are sin and error addressed where they appear? Is repentance encouraged? Is restoration sought when sin is confessed?
• Watching over the discipline of the assembly. The hard pastoral work of confronting unrepentant sin, calling members back to faith, exercising the keys (binding and loosing) Christ has entrusted to His church.
• Watching over the prayer life of the assembly. Is the church praying? Lamenting? Interceding? Confessing sin? Giving thanks?
• Watching over the worship life of the assembly. Is the assembly’s gathered worship rightly ordered? Does it serve the marks of the church?

The episkopē is comprehensive but not autocratic. The Lutheran tradition has consistently held that the pastor’s oversight is exercised through the means Christ has appointed — primarily through the preaching of the Word and the administration of the sacraments — not through hierarchical power or coercive control. The pastor watches over the assembly by serving it with the gifts Christ has given to His church.

Second, the threefold ministry (bishop, presbyter, deacon) that developed in the early second century is a salutary historical arrangement but is not divinely mandated and is not what makes the church the church. Confessional Lutheran polity has varied considerably on the question of episcopal structure, and the variety is permissible within the same confession of faith.

By the early second century, in the letters of Ignatius of Antioch (around AD 110), a clear threefold ministry is established in most regions: one bishop, multiple presbyters, multiple deacons in each local church. Ignatius treats this structure as fundamental and urges churches to maintain it. He writes, “Be subject to the bishop as to Jesus Christ” (Smyrnaeans 8:1). The hierarchy is sharper in Ignatius than in the New Testament — the bishop is now clearly distinct from the presbyters, with whom he is associated but over whom he stands. By the third and fourth centuries, the bishop has become the ordinary minister of ordination (only bishops can ordain priests and deacons), the holder of distinct apostolic succession, the head of a specific diocese, and in some regions a substantial political figure.

The Lutheran Reformation rejected the medieval Catholic claim that the threefold ministry with sacramental episcopal succession is essential to the church’s identity. The Augsburg Confession Article XXVIII addresses the power of bishops at length, distinguishing the spiritual authority that belongs to the office of oversight (preaching the gospel, forgiving sins, rejecting false teaching, exercising the keys) from the temporal authority that bishops had accumulated in the medieval period (lord-bishop status, political power, control of significant resources). AC XXVIII concedes that “the following jurisdiction belongs to the bishops as bishops, that is to say, to those to whom the ministry of Word and sacraments has been entrusted: to forgive sins, to reject teaching that opposes the gospel, and to exclude from the communion of the church the ungodly whose ungodliness is known” — but this is the authority of any pastor, by virtue of the office of the public ministry, not a distinctive authority that belongs to bishops as a separate order over presbyters.

The Lutheran tradition has not denied that the threefold ministry can be a salutary arrangement. Lutheran churches in Scandinavia and parts of Germany retain bishops, sometimes with claims to apostolic succession. The Church of Sweden, for example, maintains a succession of bishops from the pre-Reformation period; the Reformation in Sweden was conducted without breaking episcopal succession. Other European Lutheran churches retain bishops without insisting on succession. Some Lutheran churches in North America have bishops as a distinct administrative office (the Evangelical Lutheran Church in America uses the title); others have presidents of synods or districts with similar administrative roles but without the “bishop” title; others have purely congregational or synodical structures (LCMS, AFLC, WELS, ELS, ELDoNA). All are within the Lutheran tradition. All confess the same gospel, administer the same sacraments, hold the same understanding of the pastoral office as one office instituted by Christ for the church.

The variety is permissible because the Augsburg Confession’s principle that “it is enough for the true unity of the Christian church that the gospel is preached harmoniously according to a pure understanding and the sacraments are administered in conformity with the divine Word” (AC VII) extends to polity questions. Whether a Lutheran church has bishops, presidents, district overseers, or no synodical office at all, the church is the church wherever the marks of the church are present. The polity arrangements are matters of order, salutary or unsalutary depending on the circumstances and the wisdom with which they are administered, but not constitutive of the church’s identity.

This pushes back against several alternatives:

The Roman Catholic insistence that the threefold ministry with sacramental episcopal succession is essential to the church’s identity, with the further claim that the Roman Pontiff is the visible head of the universal church. The Lutheran response: the church is where the marks are present; the succession of bishops, however historically valuable, is not what constitutes the church; the papacy specifically is not a divinely instituted office.

The Eastern Orthodox emphasis on apostolic succession through the episcopate as constitutive of the church, alongside the broader emphasis on the conciliar tradition and the patristic theological inheritance. The Lutheran response is similar to the Catholic response: the marks of the church identify the church, not the succession of bishops; succession is salutary but not essential.

The Anglican via media that treats the historic episcopate as one of four essential marks (the Chicago-Lambeth Quadrilateral, formulated in 1886 and 1888). The Lutheran response: the historic episcopate may be salutary but is not what makes the church the church; the marks of the church are Word and Sacrament, not episcopal succession.

The anti-episcopal Protestantism that rejects any structured oversight as such, sometimes appealing to “every-member ministry” or congregational autonomy in absolute terms. The Lutheran response: the New Testament clearly establishes the office of the public ministry, including the function of oversight (episkopē); the question of how oversight is administratively organized is a matter of order, but oversight itself is not optional. Christ has given the office to the church; the church neither invented it nor can dispense with it.

Third, Christ Himself is the chief episkopos — “the shepherd and guardian of your souls” (1 Peter 2:25, NET). The human pastor’s oversight is derivative and ministerial; the ultimate oversight belongs to Christ. This shapes how Lutheran theology understands what the pastor does.

The pastor does not own the assembly. The pastor does not have final authority over the assembly. The pastor’s oversight is exercised on behalf of Christ, by the gifts Christ has given to the church, for the benefit of the assembly that belongs to Christ. The pastor who treats the office as a personal domain — as if he were the lord of his congregation — has departed from the New Testament’s actual structure of the office. The pastor who exercises oversight humbly, recognizing that Christ is the true Bishop, serves the assembly as the New Testament intends.

This shaped Luther’s rejection of the medieval lord-bishop model. The medieval bishop was, in many cases, a feudal lord with substantial political power, vast estates, military authority, and a position in the imperial diet. The bishop was often more like a secular nobleman than a spiritual servant. The Lutheran Reformation rejected this entire structure — not by denying the office of oversight as such, but by insisting that the office is exercised through Word and Sacrament, in service to the assembly, under the headship of Christ. The 1 Peter 5:2–3 instructions — willingly, eagerly, as examples, not domineering — describe how Lutheran bishops and pastors are to exercise their office, regardless of the particular administrative titles their tradition uses.

The pastoral payoff: when you think about the man who exercises pastoral oversight in your congregation, see what is actually happening. He is not lord; he is servant. He is not the source of authority; he is its conduit. The authority comes from Christ, exercised through Word and Sacrament, mediated through the office Christ has established for the church. The pastor watches over the flock because Christ is the chief Shepherd and Overseer, and the pastor stands in His service. Honor the office; pray for the man; receive the oversight as part of Christ’s care for His church.

Where People Get It Wrong

Three common ways.

The first is identifying the New Testament episkopos with the developed medieval episcopate. The Lutheran response: the New Testament word is simpler — overseer of the local assembly, normally the same person as the presbyteros; the developed medieval structure with diocesan administration, exclusive ordination authority, and feudal political power is a post-apostolic development that goes substantially beyond the New Testament’s actual usage.

The second is treating “bishop” as a divinely-mandated separate order from “presbyter.” The Lutheran response: the New Testament uses the words interchangeably; the threefold ministry of bishop, presbyter, and deacon is a salutary historical arrangement that emerged in the early second century but is not de iure divino. Lutheran confessional bodies that retain bishops do so as a matter of salutary order; Lutheran confessional bodies that do not retain bishops are equally within the Lutheran tradition because the polity question is not constitutive of the church’s identity.

The third is the lord-bishop model — treating the office as a position of lordship over the assembly, with the pastor or bishop as the master rather than the servant. The Lutheran response: Matthew 20:25–26 is decisive — “But Jesus called them and said, ‘You know that the rulers of the Gentiles lord it over them, and those in high positions use their authority over them. It must not be this way among you! Instead whoever wants to be great among you must be your servant,’.” The office of oversight is service, not lordship. The pastor who treats his office as personal domain has departed from the New Testament’s structure.

A fourth pattern worth noting: reducing oversight to administrative function alone. Some modern traditions have treated the episkopos / bishop / pastor primarily as a manager — the one who runs the institution, balances the budget, hires the staff, attends the synodical meetings. These are real responsibilities and not to be despised, but they are not the heart of episkopē. The heart of oversight is doctrinal — watching over what is preached and taught, ensuring that the gospel is rightly proclaimed, refuting error, instructing the assembly in sound doctrine. Titus 1:9 names this dimension explicitly. An oversight stripped of its doctrinal substance has lost what makes the New Testament office what it is.

A fifth pattern: treating apostolic succession through the episcopate as the church’s essence. The Roman Catholic, Eastern Orthodox, and Anglo-Catholic insistence on a continuous laying-on-of-hands from the apostles as constitutive of the church’s identity. The Lutheran response: the marks of the church identify the church; succession may be a salutary historical reality but is not constitutive; the gospel preached and the sacraments administered are what make the church the church, not the institutional pedigree of the men administering them.

A sixth pattern: anti-episcopal Protestantism that rejects oversight altogether. The opposite error from clericalism. Some traditions have treated any structured oversight as inherently corrupting, preferring purely congregational or charismatic leadership without distinct office. The Lutheran response: the New Testament clearly establishes the office (AC V), including the function of oversight (episkopē); the question of how oversight is organized administratively is one question, whether there is to be oversight at all is another. The office is Christ’s gift to the church and cannot be dispensed with.

So What

The man who exercises pastoral oversight in your congregation is an episkopos — an overseer of the assembly. He watches over the doctrine, the life, the worship, the discipline of the people gathered there. He does this not as a lord but as a servant; not by his own authority but by the office Christ has established for the church. He is also the same man Presbyteros named as your presbyteros — the elder, the called and ordained servant of the Word. One office, two angles. One man, multiple titles. One mission: to serve the assembly with the gifts Christ has given.

For Sunday school teachers and Bible study leaders: when you teach a passage with “overseer” or “bishop” language, watch for the episkopos. The New Testament word is simple — one who oversees. The developed medieval understanding of “bishop” as a separate order with apostolic succession and diocesan administrative power is post-apostolic development that goes beyond the New Testament’s actual usage. Help your students see that the same man is presbyteros and episkopos in the New Testament; the words name different angles of one office. Help them see that confessional Lutherans have differed on questions of polity — whether to have bishops, what their administrative role is, what title to use — while agreeing on the substance of the office and the marks of the church.

For yourself: when you receive the oversight of your pastor — when he preaches the Word to you, administers the sacraments to you, exhorts you when you sin, comforts you when you suffer, gives counsel from Scripture when you ask — remember whose oversight is finally being exercised. Christ is the chief Overseer of your soul (1 Peter 2:25). The pastor serves Christ’s oversight by serving you. The structure is grace; the office is gift; the man is your servant in Christ. Pray for him. Honor the office. Recognize that the gifts brought through him are Christ’s, not his own.

The related entry on Diakonos treats the servant or deacon, an office distinct from but related to the presbyteros/episkopos office in the apostolic-era church. For the hope shared by those who serve and those they serve, see Zoe (life), Hypostasis (substance and assurance), and Parousia (the coming of Christ).
