Early Christianity In the
Apostolic Age (largely the
1st century) the Christian Church comprised an indefinite number of local churches that in the initial years looked to the first church at
Jerusalem as its main centre and point of reference. But, by the
4th century, it had developed a system whereby the
bishop of the capital of each civil province (the
metropolitan bishop) normally held certain rights over the bishops of the other cities of the province (later called
suffragan bishops). Of the three sees that the
First Council of Nicaea was to recognize as having such extraprovincial power,
Rome is the one for which records are most available. The
church in Rome intervened in other communities to help resolve conflicts.
Pope Clement I did so in
Corinth in the end of the 1st century. In the beginning of the 2nd century,
Ignatius,
Bishop of Antioch, speaks of the Church of Rome as "presiding in the region of the Romans" (ἥτις προκάθηται ἐν τόπῳ χωρίου Ῥωμαίων). The first records of the exercise of authority by
Antioch outside its own province of
Syria date from the late 2nd century, when
Serapion of Antioch intervened in
Rhosus, a town in Cilicia, and also consecrated the third
Bishop of Edessa, outside the
Roman Empire. Bishops participating in councils held at Antioch in the middle of the 3rd century came not only from Syria, but also from
Palestine,
Arabia, and eastern
Asia Minor.
Dionysius of Alexandria spoke of these bishops as forming the "episcopate of the Orient", mentioning Demetrian, bishop of Antioch, in the first place. In Egypt and the nearby African territories the bishop of
Alexandria was at first the only metropolitan. When other metropolitan sees were established there, the bishop of Alexandria became known as the archbishop. In the mid-3rd century,
Heraclas of Alexandria exercised his power as archbishop by deposing and replacing the Bishop of Thmuis. Thus Rome, Alexandria and Antioch had grown in ecclesiastical prominence such that by the early 4th century, they had long-recognised jurisdiction over more than one province of bishops each. Alexandria had attained primacy over
Roman Egypt,
Roman Libya, and
Pentapolis. Rome had
Primatial authority over provinces within 100 miles of the city.
Council of Nicaea The
First Council of Nicaea in 325, in whose sixth
canon the title "metropolitan" appears for the first time, sanctioned the existing grouping of sees by provinces of the Roman empire, Immediately after mentioning the special traditions of wider authority of Rome, Alexandria and Antioch, the same canon speaks of the organization under metropolitans, which was also the subject of two previous canons. In this system, the bishop of the capital of each
Roman province (the
metropolitan) possessed certain rights with regard to the bishops of other cities of the province (
suffragans). In its seventh canon, the Council attributed special honour, but not metropolitan authority, to the Bishop of
Jerusalem, which was then called
Aelia, and was in the province (
Syria Palaestina) whose capital and Metropolitan was
Caesarea.
Later councils With the imperial capital having moved to
Byzantium in 330, the re-named city of
Constantinople became increasingly important in church affairs of the Greek East. The
First Council of Constantinople (381) decreed in a canon of disputed validity: "The Bishop of Constantinople, however, shall have the prerogative of honour after the Bishop of Rome; because Constantinople is New Rome." This "prerogative of honour", though recognising the new Metropolitan status of the Capital See, did not entail jurisdiction outside his own "diocese". The Emperor
Theodosius I, who called the Council, divided the eastern Roman Empire into five "dioceses": Egypt (under Alexandria),
the East (under Antioch),
Asia (under
Ephesus),
Pontus (under
Caesarea Cappadociae), and
Thrace (originally under
Heraclea, later under Constantinople). The Council also decreed: "The bishops are not to go beyond their dioceses to churches lying outside of their bounds, nor bring confusion on the churches; but let the Bishop of Alexandria, according to the canons, alone administer the affairs of Egypt; and let the bishops of the East manage the East alone, the privileges of the Church in Antioch, which are mentioned in the canons of
Nicea, being preserved; and let the bishops of the Asian Diocese administer the Asian affairs only; and the Pontic bishops only Pontic matters; and the Thracian bishops only Thracian affairs." The transfer of the capital of the empire from Rome to Constantinople in 330 enabled the latter to free itself from its ecclesiastical dependency on Heraclea and in little more than half a century to obtain this recognition of next-after-Rome ranking from the first Council held within its walls. Alexandria's objections to Constantinople's promotion, which led to a constant struggle between the two sees in the first half of the 5th century, were supported, at least until the
Fourth Council of Constantinople of 869–870, by Rome, which proposed the theory that the most important sees were the three Petrine ones, with Rome in first place. It is popularly believed that it was only until the mid-6th century that the Latin Church recognized it as ecumenical,
Archbishop Atticus would do much to expand the jurisdictional reach of Constantinople in the early 5th century. The
Council of Ephesus (431) defended the independence of the Church in
Cyprus against the supra-metropolitan interference by Antioch, but in the same period Jerusalem succeeded in gaining supra-metropolitan power over the three provinces of Palestine. After the
Council of Chalcedon (451), the position of the Pentarchy's Patriarchate of Alexandria was weakened by a division in which the great majority of its Christian population followed the form of Christianity that its opponents called
Miaphysitism.
Pope Leo I, whose delegates were absent when this resolution was passed and who protested against it, recognized the council as ecumenical and confirmed its doctrinal decrees, but rejected canon 28, on the ground that it contravened the sixth canon of Nicaea and infringed the rights of Alexandria and Antioch. By that time, Constantinople, as the permanent residence of the emperor, had enormous influence. Thus in little more than a hundred years the structural arrangement by provinces envisaged by the First Council of Nicaea was, according to John H. Erickson, transformed into a system of five large divisions headed by the bishops of Rome, Constantinople, Alexandria, Antioch, and Jerusalem. He does not use for these divisions the term
patriarchate because the term
patriarch as a uniform term for the heads of the divisions came into use only in the time of Emperor Justinian I in the following century, and because there is little suggestion that the divisions were regarded as quasi-sovereign entities, as patriarchates are in Eastern Orthodox ecclesiology. Because of the decision of the Council of Ephesus, Cyprus maintained its independence from the Antioch division, and the arrangement did not apply outside the empire, where separate "catholicates" developed in
Mesopotamia (
Church of the East) and
Armenia (
Armenian Church). ==Formulation of the pentarchy theory==
