The First Council of Nicaea was a council of Christian bishops convened in the Bithynian city of Nicaea (now İznik, Turkey) by the Roman Emperor Constantine I, also known as the First Ecumenical Council. It met from May until the end of July 325.
This ecumenical council was the first of many efforts to attain consensus in the church through an assembly representing all Christendom. Hosius of Corduba may have presided over its deliberations. Attended by at least 200 bishops, its main accomplishments were the settlement of the Christological issue of the divine nature of God the Son and his relationship to God the Father, the construction of the first part of the Nicene Creed, the mandating of uniform observance of the date of Easter, and the promulgation of early canon law.
Background
Alexandrian controversies
The major impetus for the calling of the Council of Nicaea arose in a theological dispute among the Christian clergy of Alexandria concerning the nature of Jesus, his origin, and relation to God the Father. Scholars propose dates between 318 and 322 for the beginning of the dispute. The precise origins of the controversy are unclear, but the principal actors were Archbishop Alexander of Alexandria and the presbyter Arius. Arius' teachings are known partially from a few pieces of his writings which survive, but principally from his opponents, primarily Alexander and Athanasius of Alexandria. Arius criticized Alexander's teachings on Christology; Alexander taught that Jesus as God the Son was eternally generated from the Father, while Arius and his followers asserted that the Father alone was eternal, and that the Son was created or begotten by the Father, and thus had a defined point of origin and was subordinate to the Father. Arius accused Alexander of following the teachings of Sabellius, who taught that the Father, Son, and Holy Spirit were one person, rather than the view held throughout the east that they were distinct. Alexander called a local council of bishops from Egypt and Libya, which sided with Alexander's view. Arius refused to subscribe to the council's decision, and he and several followers were excommunicated and exiled from Alexandria by Alexander. Arius then traveled to churches around the Roman east and wrote to bishops to gain support of his view. Among Arius' supporters were Eusebius of Nicomedia and Eusebius of Caesarea, and they advocated for his view and his restoration to the church in Alexandria. Alexander also circulated letters defending his own position.
Parallel to the theological controversy between Alexander and Arius was the Melitian schism in the Alexandrian church. Melitius, bishop of Lycopolis, had acted in the stead of the imprisoned bishop Peter I of Alexandria during the Diocletianic Persecution, but after Peter's death in 311 refused to give up his right to ordain clergy or recognize the authority of Peter's successors Achillas or Alexander.
Constantine and the calling of the council
In 324, the western Roman emperor Constantine defeated the eastern emperor Licinius and became the sole ruler of the Roman Empire. It was at this time that—likely from Eusebius of Nicomedia—he became aware of the controversy between Alexander and Arius. Constantine wrote a letter to the two, urging them to end their dispute and reconcile. This was not Constantine's first direct involvement in ecclesiastical controversy; he had previously attempted to resolve a schism over Donatism in North Africa, first appointing Miltiades, Bishop of Rome, to hear the dispute (with the instruction "I do not wish you to leave schism or division of any kind anywhere.") and then calling the Council of Arles.
Constantine's letter was carried to Alexandria by Bishop Hosius of Corduba as his representative. Hosius apparently then presided over a synod at Alexandria concerning the date of Easter, before calling a council of Eastern bishops in Antioch. This council endorsed Alexander's position and issuing a statement of faith that held that the Son was "begotten not from non-existence, but from the Father, not as made, but as genuine product" and contained anathemas against Arius. Eusebius of Caesaria was also temporarily excommunicated because of his contention that the Father and the Son were of two different natures.
Hosius prompted Constantine to call for a council.
The bishops were then to assemble in Ancyra in Asia Minor for a "great and hierarchic council", either at their own impetus or Constantine's command. Constantine moved the council to Nicaea in Bithynia, a venue that would allow him to attend personally (due to its proximity to his capital at Nicomedia) and would allow easier access for bishops from throughout the empire. The emperor had also planned a commemoration of the twentieth year of his reign in Nicaea.
Attendance
The expenses of the council, including the travel of the bishops, were paid by the imperial treasury. Contemporary reports of attendance range from 250 to 300, with the figure of 318 given by Athanasius of Antioch becoming traditionally accepted. 318 is also the number of members of Abraham's household given in the Book of Genesis. Lists of signatories to the final decisions of the council contain 200–220 names. With presbyters and deacons attending each bishop, the total attendance may have been between 1200 and 1900.
Almost all bishops were from the Eastern Church, including about twenty from Egypt and Libya, fifty from Palestine and Syria, and more than one hundred from Asia
Minor. One bishop each from Persia and Scythia were present.
The few western attendees were Hosius, Caecilianus of Carthage, Nicasius of Die, Marcus of Calabria, Domnus of Pannonia, and Victor and Vicentius, and two presbyters representing Pope Sylvester I. Of the eastern bishops, the principal supporters of Arius were Eusebius of Nicomedia, Eusebius of Caesarea, Menophantus of Ephesus, Patrophilus of Scythopolis, Narcissus of Neronias, Theonas of Marmarike, Secundus of Ptolemais, and Theognis of Nicaea. The principal anti-Arians included Alexander of Alexandria, Eustathius of Antioch, Marcellus of Ancyra and Macarius of Jerusalem.
The council was held in Nicea's imperial palace. The bishops most likely assembled in a rectangular basilica hall based on Eusebius of Caearea's description.
Overview
Constantine opened the council with a formal entrance after the bishops arrived, with Eusebius describing him as "like some heavenly angel of God, his bright mantle shedding lustre like beams of light, shining with the fiery radiance of a purple robe, and decorated with the dazzling brilliance of gold and precious stones." He then gave an opening speech in Latin (rather than the Greek spoken by most of the attendees). Fifth-century church historian Socrates of Constantinople gives the date of the opening as 20 May 325, though it may have been later in June.
It is most likely that Hosius presided over the council's debates and proceedings as Constantine's representative. Constantine did join in the debates of the council (in Greek), but did not see himself as a voting member as he was not a bishop. No detailed acta of the council exist as they do for later councils, so the exact sequence of the council's debates is uncertain. Church councils at the time were modeled after the proceedings of the Roman Senate, with the presiding officer having a large degree of control, and participants speaking in turn based on hierarchy. Probably the first matter considered was the status of Eusebius of Caesarea and the other bishops excommunicated at Antioch, as this would determine whether they could participate in the rest of the council. According to Eusebius, his profession of faith was accepted and he was restored. An account by Eustathius of Antioch records a statement of faith by a Eusebius being rejected by the council, though this was likely Eusebius of Nicomedia.
A statement of faith based on earlier creeds was drafted (possibly by a smaller committee), and each line was debated by the council. All but two bishops subscribed to the final form of the creed as adopted. In addition to the Arian question, the council also considered the calculation of Easter, and adopted the Roman and Alexandrian method over the objection of several eastern bishops. The bishops also agreed to a resolution on the Melitian schism and issued twenty canons. The council closed in the first weeks of July, with the bishops invited to attend Constantine's celebration of his twentieth anniversary on the throne on 25 July. Both the bishops and the emperor issued letters recounting the councils' decisions to be circulated throughout the empire.
Ecumenical Council
The First Council of Nicaea was the first ecumenical council of the church. Nicaea "was the first time that any attempt had been made to summon a general council of the whole church at which, at least in theory, the church in every part of the Roman Empire should be represented".
Derived from Greek (Ancient Greek: οἰκουμένη, romanized: oikouménē, lit. 'the inhabited one'), "ecumenical" means "worldwide" but generally is assumed to be limited to the known inhabited Earth, and at this time in history is nearly synonymous with the Roman Empire. The earliest extant uses of the term for a council are Eusebius' Life of Constantine around 338, which states "he convoked an ecumenical council" (σύνοδον οἰκουμενικὴν συνεκρότει, sýnodon oikoumenikḕn synekrótei) and a letter in 382 to Pope Damasus I and the Latin bishops from the First Council of Constantinople.
Historically significant as the first effort to attain consensus in the church through an assembly representing all of Christendom, the council was the first occasion where the technical aspects of Christology were discussed. Through it a precedent was set for subsequent general councils to adopt creeds and canons. This council is generally considered the beginning of the period of the first seven ecumenical councils in the history of Christianity.
Outcomes
Nicene Creed
The council formulated a creed, a declaration and summary of the Christian faith. Several creeds were already in existence; many creeds were acceptable to the members of the council, including Arius. From earliest times, various creeds served as a means of identification for Christians, as a means of inclusion and recognition, especially at baptism. In Rome, for example, the Apostles' Creed was popular, especially for use in Lent and the Easter season. In the Council of Nicaea, one specific creed was used to define the Church's faith clearly, to include those who professed it, and to exclude those who did not.
The original Nicene Creed read as follows:
We believe in one God, the Father almighty,
maker of all things visible and invisible;
And in one Lord, Jesus Christ, the Son of God,
begotten from the Father, only-begotten,
that is, from the substance of the Father,
God from God, light from light,
true God from true God, begotten not made,
of one substance with the Father,
through Whom all things came into being,
things in heaven and things on earth,
Who because of us men and because of our salvation came down,
and became incarnate and became man, and suffered,
and rose again on the third day, and ascended to the heavens,
and will come to judge the living and dead,
And in the Holy Spirit.
But as for those who say, There was when He was not,
and, Before being born He was not,
and that He came into existence out of nothing,
or who assert that the Son of God is of a different hypostasis or substance,
or created, or is subject to alteration or change
– these the Catholic and apostolic Church anathematizes.
The creed was amended by the First Council of Constantinople in 381.
Distinctive elements
Some distinctive elements in the Nicene Creed, perhaps from the hand of Hosius of Cordova, were added, some specifically to counter the Arian point of view.
- Jesus Christ is described as "Light from Light, true God from true God", proclaiming his divinity.
- Jesus Christ is said to be "begotten, not made", asserting that he was not a mere creature, brought into being out of nothing, but the true Son of God, brought into being "from the substance of the Father".
- He is said to be "of one substance with the Father", proclaiming that although Jesus Christ is "true God" and God the Father is also "true God", they are "of one substance". The Greek term homoousios, consubstantial (i.e. of the same substance) is ascribed by Eusebius of Caesarea to Constantine who, on this particular point, may have chosen to exercise his authority. The significance of this clause, however, is ambiguous as to the extent in which Jesus Christ and God the Father are "of one substance", and the issues it raised would be seriously controverted in the future.
