ἐπίσκοπος

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

The word is bishop.

Like “priest” (which we treated in the previous chapter), “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 (Chapter 45), 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 chapter on episkopos. It continues Part VI on the church and its offices. The chapter’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 (“if anyone aspires to the episkopē”), referring to the office of overseer as a category.

The dominant theological usage is the first — the local Christian leader who exercises oversight. The chapter 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

“Now from Miletus he sent to Ephesus and called the elders of the church to come to him… ‘Pay careful attention to yourselves and to all the flock, in which the Holy Spirit has made you overseers, to care for the church of God, which he obtained with his own blood.’” (Acts 20:17, 28, ESV)

Already cited in the previous chapter. 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.

“Paul and Timothy, servants of Christ Jesus, To all the saints in Christ Jesus who are at Philippi, with the overseers and deacons…” (Philippians 1:1, ESV)

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.

“The saying is trustworthy: If anyone aspires to the office of overseer, he desires a noble task. Therefore an overseer must be above reproach, the husband of one wife, sober-minded, self-controlled, respectable, hospitable, able to teach, not a drunkard, not violent but gentle, not quarrelsome, not a lover of money. He must manage his own household well, with all dignity keeping his children submissive… He must not be a recent convert… Moreover, he must be well thought of by outsiders…” (1 Timothy 3:1–7, ESV)

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: “able to teach” (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.

“This is why I left you in Crete, so that you might put what remained into order, and appoint elders in every town as I directed you — if anyone is above reproach, the husband of one wife, and his children are believers and not open to the charge of debauchery or insubordination. For an overseer, as God’s steward, must be above reproach. He must not be arrogant or quick-tempered or a drunkard or violent or greedy for gain, but hospitable, a lover of good, self-controlled, upright, holy, and disciplined. He must hold firm to the trustworthy word as taught, so that he may be able to give instruction in sound doctrine and also to rebuke those who contradict it.” (Titus 1:5–9, ESV)

Already cited in the previous chapter. 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 “hold firm to the trustworthy word as taught, so that he may be able to give instruction in sound doctrine and also to rebuke those who contradict 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.

“Shepherd the flock of God that is among you, exercising oversight, not under compulsion, but willingly, as God would have you; not for shameful gain, but eagerly; not domineering over those in your charge, but being examples to the flock.” (1 Peter 5:2–3, ESV)

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 straying like sheep, but have now returned to the Shepherd and Overseer of your souls.” (1 Peter 2:25, ESV)

The Christological climax. Christ Himself is named poimēn kai episkopos tōn psychōn humōn — “the Shepherd and Overseer 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.
