A bishop is an ordained or consecrated member of the Christian clergy who is generally entrusted with a position of authority and oversight. Within the Roman Catholic, Eastern Orthodox, Oriental Orthodox Churches, in the Assyrian Church of the East, in the Independent Catholic Churches, and in the Anglican churches, bishops claim Apostolic succession, a direct historical lineage dating back to the original Twelve Apostles. Within these churches, bishops can ordain clergy including other bishops. Some Protestant churches including the Lutheran and Methodist churches have bishops serving similar functions as well, though not always understood to be within Apostolic succession in the same sense.
The office of bishop was already quite distinct from that of priest in the writings of Ignatius of Antioch (died c. 107),[citation needed] and by the middle of the second century all the chief centres of Christianity were headed by bishops, a form of organization that remained universal until the Protestant Reformation.[1]
The earliest organization of the Christian churches in Jerusalem was similar to that of Jewish synagogues, which were governed by a council of elders (presbyteroi). In Acts 11:30 and 15:22, we see this collegiate system of government in Jerusalem, and, in Acts 14:23, the Apostle Paul ordains elders in the churches he founded.
Presbyters were apparently identical to overseers (episkopoi, i.e., bishops), as in Acts 20:17, Titus 1:5,7 and 1 Peter 5:1.[2][3] The earliest writings of the Apostolic Fathers, the Didache and the First Epistle of Clement for example, show the church recognized two local church offices—elders (interchangeable term with overseer) and deacon.
The beginnings of a single ruling bishop can perhaps be traced to the offices occupied by Timothy and Titus in the New Testament. We are told that Paul had left Timothy in Ephesus and Titus in Crete to oversee the local church (1 Tim. 1:3 and Titus 1:5). Paul commands them to ordain presybters/bishops and to exercise general oversight, telling Titus to "rebuke with all authority" (Titus 2:15).
Various Christian communities would have had a group of presbyter-bishops functioning as leaders of the local church. Eventually this evolved into a monarchical episcopacy in certain cities.[4] The monarchical episcopacy probably developed in other churches in Christianity before it took shape in Rome. For example, it has been conjectured that Antioch may have been one of the first Christian communities to have adopted such a structure.[4] The emergence of a single bishop in Rome probably did not arise until the middle of the second century. Linus, Cletus and Clement were probably prominent presbyter-bishops but not necessarily monarchical bishops.[5] Eventually, Rome followed the example of other Christian communities and structured itself after the model of the empire with one presbyter bishop in charge ..."[6] The organizational structure subsequently evolved into the present form of one bishop supported by a college of presbyters.[4]
It is certain that the office of bishop and presbyter were clearly distinguished by the [[Christianity in the 2nd century}second century]], as the church was facing the dual pressures of persecution and internal schism, resulting in three distinct local offices: bishop, elder (presbyter) and deacon. This is best seen in the 2nd century writings of St. Ignatius of Antioch.
The bishop was understood mainly as the president of the council of presbyters, and so the bishop came to be distinguished both in honor and in prerogative from the presbyters, who were seen as deriving their authority by means of delegation from the bishop. Each Episcopal see had its own bishop and his presence was necessary to consecrate any gathering of the church.
Eventually, as Christendom grew, individual congregations no longer were served directly by a bishop. The bishop in a large city (the Metropolitan bishop) would appoint a presbyter to pastor the flock in each congregation, acting as his delegate.
Around the end of the first century, the church's organization becomes clearer in historical documents. In the works of the Apostolic Fathers, and Ignatius of Antioch in particular, the role of the episkopos, or bishop, became more important or, rather, already was very important and being clearly defined.
"Plainly therefore we ought to regard the bishop as the Lord Himself" — Epistle of Ignatius to the Ephesians 6:1.
"your godly bishop" — Epistle of Ignatius to the Magnesians 2:1.
"the bishop presiding after the likeness of God and the presbyters after the likeness of the council of the Apostles, with the deacons also who are most dear to me, having been entrusted with the diaconate of Jesus Christ" — Epistle of Ignatius to the Magnesians 6:1.
"Therefore as the Lord did nothing without the Father, [being united with Him], either by Himself or by the Apostles, so neither do ye anything without the bishop and the presbyters." — Epistle of Ignatius to the Magnesians 7:1.
"Be obedient to the bishop and to one another, as Jesus Christ was to the Father [according to the flesh], and as the Apostles were to Christ and to the Father, that there may be union both of flesh and of spirit." — Epistle of Ignatius to the Magnesians 13:2.
"In like manner let all men respect the deacons as Jesus Christ, even as they should respect the bishop as being a type of the Father and the presbyters as the council of God and as the college of Apostles. Apart from these there is not even the name of a church." — Epistle of Ignatius to the Trallesians 3:1.
"follow your bishop, as Jesus Christ followed the Father, and the presbytery as the Apostles; and to the deacons pay respect, as to God's commandment" — Epistle of Ignatius to the Smyrnans 8:1.
"He that honoureth the bishop is honoured of God; he that doeth aught without the knowledge of the bishop rendereth service to the devil" — Epistle of Ignatius to the Smyrnans 9:1.— Lightfoot translation.
It is clear that, by this period, a single bishop was expected to lead the church in each centre of Christian mission, supported by a council of presbyters (a distinct and subordinate position at least by this time) with a pool of deacons. As the Church continued to expand, new churches in important cities gained their own bishop. Churches in the regions outside an important city were served by Chorbishop, an official rank of bishops. However, soon, presbyters and deacons were sent from bishop of a city church. Graudually priests replaced the chorbishops. Thus, in time, the bishop changed from being the leader of a single church confined to an urban area to being the leader of the churches of a given geographical area.[7]
Clement of Alexandria (end of the 2nd century) writes about the ordination of a certain Zachæus as bishop by the imposition of Simon Peter Bar-Jonah's hands. The words bishop and ordination are used in their technical meaning by the same Clement of Alexandria.[8] The bishops in the 2nd century are defined also as the only clergy to whom the ordination to priesthood (presbyterate) and diaconate is entrusted: "a priest (presbyter) lays on hands, but does not ordain." (cheirothetei ou cheirotonei[9])
At the beginning of the 3rd century, Hippolytus of Rome describes another feature of the ministry of a bishop, which is that of the "Spiritum primatus sacerdotii habere potestatem dimittere peccata": the primate of sacrificial priesthood and the power to forgive sins.[10]
The efficient organization of the Roman Empire became the template for the organisation of the church in the fourth century, particularly after Constantine's Edict of Milan. As the church moved from the shadows of privacy into the public forum it acquired land for churches, burials and clergy. In 391, Theodosius I decreed that any land that had been confiscated from the church by Roman authorities be returned.
The most usual term for the geographic area of a bishop's authority and ministry, the diocese, began as part of the structure of the Roman Empire under Diocletian. As Roman authority began to fail in the western portion of the empire, the church took over much of the civil administration. This can be clearly seen in the ministry of two popes: Pope Leo I in the fifth century, and Pope Gregory I in the sixth century. Both of these men were statesmen and public administrators in addition to their role as Christian pastors, teachers and leaders. In the Eastern churches, latifundia entailed to a bishop's see were much less common, the state power did not collapse the way it did in the West, and thus the tendency of bishops acquiring secular power was much weaker than in the West. However, the role of Western bishops as civil authorities, often called prince bishops, continued throughout much of the Middle Ages.
As well as being arch chancellors of the Holy Roman Empire, bishops generally served as chancellors to medieval monarchs, acting as head of the justiciary and chief chaplain. The Lord Chancellor of England was almost always a bishop up until the dismissal of Thomas Cardinal Wolsey by Henry VIII. Likewise, the position of Kanclerz in the Polish kingdom was always a bishop until the sixteenth century.
In France before the French Revolution, representatives of the clergy — in practice, bishops and abbots of the largest monasteries — comprised the First Estate of the Estates-General, until their role was abolished during the French Revolution.
The more senior bishops of the Church of England continue to sit in the House of Lords of the Parliament of the United Kingdom, as representatives of the established church, and are known as Lords Spiritual. The Bishop of Sodor and Man, whose diocese lies outside of the United Kingdom, is an ex officio member of the Legislative Council of the Isle of Man. In the past, the Bishop of Durham, known as a prince bishop, had extensive viceregal powers within his northern diocese — the power to mint money, collect taxes and raise an army to defend against the Scots.
