THE SEVEN COUNCILS.
The conciliar principle of deciding matters of doctrinal and disciplinary importance began with the Council of Jerusalem, described in Acts 15, where the Apostles met to decide whether Gentile converts should be subject to the Mosaic Law. (They were not!).
With this Council in mind, and the various local councils which met at diverse parts of the Empire in the period prior to Nicea, the Church established an important principle: In council, the members of the Church, so to speak, can together claim an authority which individually none of them possess.
The Seven Ecumenical Councils which met in the period from 325 to 787 performed two basic tasks: 1) They formulated the visible, ecclesiastical organization of the Church, setting the ranking of the Five Patriarchates; and 2) they defined, once and for all, the teachings of the Church on faith, formulating the basic dogmas concerning the Trinity and the Incarnation.
NICEA I (325).
This Council condemned the heresy of A***nism, which had contended that the Son was inferior to the Father and was, in fact, created. The Fathers here declared that the Son is one in essence (homoousios) with the Father, and formulated the first part of what eventually became the Creed the Symbol of Faith. In addition, three great Sees were singled out Rome, Alexandria and Antioch (Canon 6), and the See of Jerusalem, although still subject to the Metropolitan of Caesarea, was given the next place in honor after Antioch
(Canon 7).
CONSTANTINOPLE I (381).
This Council expanded the Nicene Creed, developing the teachings concerning the Holy Spirit, who proceeds from the Father; Who, with the Father and Son, is worshipped and glorified..., against the heresy of the Pneumatomachi (Spiritsmashers) and the Macedonians (followers of Macedonius), who could not accept the Third Person of the Trinity as equal to the other Two.
It was in this period that we see the activities of the great Cappadocian Fathers, St. Gregory Nazianzus (the Theologian), St. Basil the Great and St. Gregory of Nyssa, as well as the great Alexandrian Father, St. Athanasius the Great.
The First Council of Constantinople also decreed that Constantinople, the new capital, should hold the next place of honor after Rome, since it was now the New Rome (Canon 111).
EPHESUS (431).
This Council met to discuss the heresy of the Nestorians, who could not accept that God and Man had been united in one Person, Christ, refusing to call the Virgin Mary, Theotokos (or Birthgiver of God). Supported primarily by St. Cyril of Alexandria, this Council affirmed that Mary was truly Theotokos, since, as the Evangelist had proclaimed, the Word was made flesh (John 1:14), and the Virgin had borne a single and undivided Person Who is, at the same time, God and Man.
CHALCEDON (451).
This Council met to discuss the heresy of the Monophysites who held that in Christ the human nature had been merged into the divine, so that there was, after the divine union, only one nature. The Bishops of this Council accepted the so-called Tome of Pope St. Leo the Great of Rome, which affirmed the belief that the one and the same son, perfect in Godhead and perfect in manhood, [is] truly God and truly man...acknowledged in two natures unconfused, unchanged, undivided and inseparable. In addition, the place of Constantinople after that of Rome was confirmed, as was that of Jerusalem in the fifth place of honor.
A tragic result of this Council (and that of Ephesus prior) was the splitting apart from the main body of a large group of Christians adhering to either the Nestorian or Monophysite view. The Nestorians were found basically in Persia and Mesopotamia, and were especially decimated by the Islamic and Turkish onslaughts, whereas the Monophysites were strong in Africa (Egypt and Ethiopia the present Coptic Church), Armenia, and India (the Jacobite Church).
CONSTANTINOPLE II (553).
This Council met to further reinterpret the decrees of Chalcedon, seeking to explain how the two natures of Christ unite to form a single person. It affirmed that Jesus Christ, the Son of God, is one of the Holy Trinity, one and the same divine Person (hypostasis), Who has united personally (hypostatically) in Himself the two natures of God and Man, without fusing them together and without allowing their separation. Certain teachings of Origen, including his teaching concerning the pre-existence of the soul, among other things, were also expressly condemned.
CONSTANTINOPLE III (681).
This Council met to condemn the Monothelite heresy which held that in the union of the two natures in Christ, the human will was merged into the divine as one will, since the two natures were united into one person. The Council, however, held that if Christ has two natures, he also has two wills human and divine.
NICEA II (787).
This Council met to affirm the belief of the Orthodox that veneration of the Holy Icons was proper and necessary for a correct understanding of the Incarnation of Christ, against those who held that Icon-veneration was idolatry and that all Icons should be destroyed (Iconoclasts).
This Seventh Council was also the last of the Ecumenical Councils accepted as such by the Orthodox Church, although the possibility does exist that, in principle, more could be convened. The Iconoclast controversy did not end until after another rising of the heretics beginning in 815, which was finally suppressed by the Empress Theodora in 843.
This final victory of the Holy .Icons in 843 is known as the Triumph of Orthodoxy, and is commemorated on the First Sunday of Great Lent. Thus, with the resolution of the Iconoclast controversy, the Age of the Seven Councils came to an end.
During this same period, there were two other major currents that were to have a profound effect on the Byzantine Empire and Orthodoxy. The first of these was the rise of monasticism.
It began as a definite institution in Egypt in the 4th Century and rapidly spread across the Christian world. It literally began at a time when the persecutions had ended, and the Monks, with their austere life, were, in a real sense, martyrs when martyrdom of blood had virtually ceased. At a time when people were in danger of forgetting that life in the world the earthly kingdom was not the Kingdom of God, the Monks and their withdrawal from society, reminded Christians that God's Kingdom, in fact, is not of this world.
The second major current in this period was the rise and rapid spread of Islam, the most striking characteristic of which was the speed of its expansion. Within fifteen years after the death of Mohammed in 632, his followers had captured Syria, Palestine and Egypt, and in fifty years, they were already at the gates of Constantinople.
Within 100 years, they had swept across North Africa and through Spain. The Byzantine Empire lost the Patriarchates of Alexandria, Antioch and Jerusalem, and until the actual fall of Constantinople in 1453, the Empire was never free from attack.
THE GREAT SCHISM.
In 1054 occurred one of the greatest tragedies of the Christian world the Great Schism between the Orthodox and the Roman Catholic Churches. Officially proclaimed at Constantinople in that year by the Papal Legate, Cardinal Humbert, it was, in a sense, the culmination of a process that had been taking place for several centuries, ultimately centering on two major controversies: Papal authority and the Filioque.
Originally the two branches of Christendom had begun to drift apart because of cultural and language differences.
Then, in 800, we see a political split with the proclamation of Charlemagne as the Holy Roman Emperor there were now two! The hegemony of the Arabs over the Mediterranean and their expansion into the Balkans made direct contact difficult, if not impossible, between East and West.
And even in theology the two branches of Christendom began to differ in their basic approaches, with the Latins being more practical, the Greeks more speculative; the Latins more influenced by legal ideas nurtured by the basic concepts of Roman law, while the Greeks were influenced by worship and the Holy Liturgy; the Latins were more concerned with redemption, the Greeks with deification.
These different approaches, practiced in greater isolation from each other, eventually led to the two main theological problems outlined earlier.
The first problem was that of Papal authority. The Greeks were willing to ascribe to the Pope of Rome a primacy of honor, considering him to be the first among equals, whereas the Pope believed his power of jurisdiction to extend to the East as well as the West, the Greeks jealously guarding the autonomy of the other Patriarchates.
The Pope saw infallibility as his sole prerogative, whereas the Greeks insisted that in matters of faith, the ultimate decisions belonged to an Ecumenical Council consisting of all the Bishops of the Universal Church.
The second great problem was the Filioque (Latin and the Son), first inserted into the Creed at the Council of Toledo in Spain in 589 and later adopted by the whole Western Church.
Whereas the original wording of the Creed ran, and in the Holy Spirit, the Lord, the Giver of Life, Who proceeds from the Father..., the Latin insertion changed it to read, and in the Holy Spirit, the Lord, the Giver of Life, Who proceeds from the Father and the Son.
The Orthodox objected to this insertion on two grounds: 1) the Ecumenical Councils had expressly forbidden any changes to be introduced into the Creed, and 2) this insertion disturbed the balance between the Three Persons of the Holy Trinity, leading to a false understanding of the work of the Holy Spirit in the world.
Prior to the Schism of 1054, there had been another breach, the so-called Photian Schism, in the 9th Century, but it had been officially terminated in the latter years of the reign of Patriarch Photius.
The breach of 1054, however, although not universally applied at first, was never healed, even after several attempts to do so, most noticeably at the Council of Lyons in 1274 and the Council of Florence in 1438-9, when the Turks were already threatening Constantinople, but these reunion attempts were doomed to failure.
Probably the deciding factor in the permanence of the Schism had been the capture and sack of Constantinople by the Latin Crusaders in 1204, which forever after remained indelibly imprinted on the consciousness of the Orthodox.
In 1453, a crucial event occurred in world Orthodoxy, with the Fall of Constantinople to the Turkish Sultan, Mohammed II. The Greek-speaking Churches fell under the heavy yoke of Islam, and for nearly 500 years labored in servitude, only emerging again with the Balkan Revolutions of the 19th Century and World War I. In the meantime, the focus of Orthodoxy shifted to the North, to the domains of the Most Pious Tsars of Russia.
Notable Fathers of the Early Period.
St. Cyprian, Bishop of Carthage ( 258).
St. Cyprian, commemorated on August 31, was Bishop of Carthage during the persecutions of the Emperor Decius (250). He died as a martyr in 258, and among his many writings concerning Church life, the most important is On the Unity of the Catholic Church, which sets forth the role of the Bishop in the ecclesiastical structure.
St. Ignatius, Bishop of Antioch ( 107).
St. Ignatius was the second Bishop of Antioch and is commemorated on December 20 and January 29. Martyred in the Arena at Rome, while on his way to martyrdom, he wrote seven letters to Christian communities, as well as to St. Polycarp, which contain valuable information on the dogmas, organization and liturgy of the early Church.
St. Irenaeus of Lyons ( 202).
St. Irenaeus, who is commemorated on August 23, was a disciple of St. Polycarp, and, as a Westerner, he succeeded St. Photinus as Bishop of Lyons. His major doctrinal work is Against Heresies, which defends Orthodoxy against the Gnostics, borrowing heavily on both human reason and Holy Scripture and Tradition, serving as an important witness to Church traditions of his time.
St. Polycarp, Bishop of Smyrna ( 167).
St. Polycarp was a disciple of St. John the Theologian and is commemorated as a martyr on February 23. The account of his martyrdom, the earliest detailed account of a martyr, gives an excellent picture of his character and the steadfastness of his Christian faith.
NOTABLE FATHERS OF THE EARLY BYZANTINE PERIOD.
St. Anthony the Great ( 356).
St. Anthony, commemorated January 17, is considered to be the Father of monasticism, and The Life of St. Anthony, by St. Athanasius, presents him as a truly inspiring example of monastic ascetical perfection. During the A***n controversies, he risked his life defending the Orthodox teachings of St. Athanasius in Alexandria.
St. Athanasius the Great, Patriarch of Alexandria ( 373).
St. Athanasius, commemorated January 18 and May 2, was a great defender of the Orthodox faith during the A***n controversies and was exiled five times for his labors. Among his major writings are The Incarnation of Christ and The Life of St. Anthony, which serve as major inspirations for Orthodox theology and monastic spirituality.
St. Basil the Great, Archbishop of Caesarea in Cappadocia ( 379).
St. Basil, commemorated January 1 and January 30, was a notable theologian and spiritual writer of the 4th Century and is noted for his many writings on numerous theological and spiritual subjects, as well as commentaries on Holy Scripture. During the Sundays of Great Lent, as well as on his Feast Day (Jan. 1), the Liturgy of St. Basil the Great is served, although probably only the prayers are actually of this Saint.
St. Cyril, Patriarch of Alexandria ( 444).
St. Cyril, commemorated on January 18 and June 9, was the leader in the defense of Orthodoxy against the Nestorians, and was a firm defender of the veneration of the Virgin Mary as Theotokos. He was especially prominent in the deliberations of the Third Ecumenical Council.
St. Ephraim the Syrian ( 373-9).
St. Ephraim, commemorated January 28, was a major spiritual writer and hymnographer of the 4th Century, and is especially noted in Orthodox liturgical life for, among other things, his inspiring work, The Lenten Prayer of St. Ephraim the Syrian, which is said at all of the weekday services of Great Lent.
St. Gregory the Theologian, Archbishop of Constantinople ( 389).
St. Gregory, commemorated January 25 and 30, was a fellow student and friend of St. Basil the Great and was a leading opponent of the A***ns. He has been honored by the Church with the title Theologian, being one of only three, so honored (the others being St. John the Evangelist, and St. Simeon the New Theologian), primarily because of his Five Theological Orations.
St. Gregory, Bishop of Nyssa (4th Cent.).
St. Gregory was the younger brother of St. Basil the Great and is commemorated on January 10. He is especially known for his spiritual writings, as well as various dogmatic works, including his Great Catechism.
St. John Chrysostom, Archbishop of Constantinople ( 407).
St. John Chrysostom (the Golden-mouth), commemorated January 27 and 30 and November 13, was one of the greatest preachers of his time (late 4th Century) and was known for his zeal for Orthodoxy and his passionate defense of the poor, boldly exposing the vices of his age, for which reason he was eventually deposed and exiled.
The bulk of his works are sermons on Holy Scripture, especially the Epistles of St. Paul, as well as other ascetical and pastoral works, including his On the Priesthood. To St. John is attributed the usual Divine Liturgy, although, as in the case of that of St. Basil the Great, probably only certain prayers are properly his.
NOTABLE FATHERS OF THE LATER BYZANTINE PERIOD.
St. Gregory the Dialogist, Pope of Rome ( 604).
St. Gregory the Dialogist, commemorated March 12, was Pope of Rome in the 7th Century and was noted for his many literary works, including his Dialogues on the monastic Saints of Italy. To him is ascribed the writing-down of the beautiful Gregorian Chants as well as the Liturgy of the Presanctified Gifts, during which he is specially commemorated.
St. Gregory Palamas, Archbishop of Thessalonica ( ca. 1360).
St. Gregory, commemorated on November 14 and the Second Sunday of Great Lent, was a pious Monk of Mt. Athos, and later was elected to the See of Thessalonica as its Bishop. He is noted for his defense of the contemplative life of hesychasm (inner silence), teaching concerning the uncreated Light of Tabor and the Divine Energies of God, through which man can have true communion with God.
St. John of Damascus
(Damascene ( 776)).
St. John, commemorated December 4, was noted for his Exact Exposition of the Orthodox Faith, a major dogmatic work, as well as his zealous defense of the Holy Icons, for which he suffered the severing of his hand (miraculously restored by the prayers of the Mother of God). He is also noted for his many sermons on Feast Days, as well as numerous hymns, extensively used in Orthodox liturgical services.
St. Mark, Archbishop of Ephesus
(15th Cent.).
St. Mark, commemorated January 19, accompanied the Byzantine Emperor to the Council of Florence, and single-handedly defended the Orthodox faith against the Latins. His brilliant defense of Orthodoxy and his letters after the Council were largely responsible for the Orthodox rejection of this false Council.
St. Photius the Great, Patriarch of Constantinople ( 891).
St. Photius, commemorated February 6, was a zealous defender of Orthodoxy against the Latin error of the Filioque, for which he suffered much. He wrote on the Procession of the Holy Spirit and was responsible for the commissioning of Sts. Cyril and Methodius for the conversion of the Slavs.
St. Simeon the New Theologian ( 1021).
St. Simeon, commemorated March 12 and October 12, was noted as a brilliant spiritual writer, whose works hold a place of honor in the Phllokalia, a major monastic spiritual work. For this reason he endured persecution and also received the veneration of the Orthodox Church which honors him as the New Theologian.
