Early controversies
A long and continuing trail of broken relations among Christians began in the 2nd century when the Gnostics presented a serious doctrinal error and broke fellowship. Quartodecimanism, a dispute over the date of Easter, pitted Christians from Asia Minor against those from Rome. Montanism—which taught a radical enthusiasm, the imminent Second Coming of Christ, and a severe perfection, including abstinence from marriage—split the church. The Novatians broke fellowship with Christians who offered sacrifices to pagan gods during the persecutions of the Roman emperor Decius in ad 250. In the early 4th century the Donatists, Christians in North Africa who prided themselves as the church of the martyrs, refused to share communion with those who had lapsed (i.e., who had denied the faith under threat of death during the great persecutions of Diocletian and Galerius). They remained a powerful force in Africa into the 5th century and survived into the 7th despite opposition from church and state. This schism—like many since—reflected regional, national, cultural, and economic differences between the poor, rural North African Christians and the sophisticated, urban Romans.
In each century leaders and churches sought to reconcile these divisions and to manifest the visible unity of Christ’s church. But in the 5th century a severe break in the unity of the church took place. The public issues were doctrinal consensus and heresy, yet in the midst of doctrinal controversy alienation was prompted by political, cultural, philosophical, and linguistic differences. Tensions increased as the church began to define the relationship between God the Father and God the Son and later the relation between the divine and human elements in the nature and person of Jesus Christ. The first four ecumenical councils—at Nicaea (ad 325), Constantinople (381), Ephesus (431), and Chalcedon (451)—defined the consensus to be taught and believed, articulating this faith in the Nicene Creed and the Chalcedonian Definition, which stated that Jesus is the only begotten Son of God, true man, and true God, one person in “two natures without confusion, without change, without division, without separation.” Some groups deviated doctrinally from the consensus developed in the councils. The Nestorians taught that there are two distinct persons in the incarnate Christ and two natures conjoined as one. Monophysites taught that there is one single nature, primarily divine. Several churches refused to accept the doctrinal and disciplinary decisions of Ephesus and Chalcedon and formed their own communities. These pre-Chalcedonian or non-Chalcedonian churches, including the Oriental Orthodox churches, became great missionary churches and spread to Africa and throughout Central, South, and East Asia.
The schism of 1054
The greatest schism in church history occurred between the church of Constantinople and the church of Rome. While 1054 is the symbolic date of the separation, the agonizing division was six centuries in the making and the result of several different issues. The Eastern church sharply disagreed when the Western church introduced into the Nicene Creed the doctrine that the Holy Spirit proceeds not from the Father alone—as earlier Church Fathers taught—but from the Father and the Son (Latin: Filioque). When the Roman Empire was divided into two zones, Latin-speaking Rome began to claim superiority over Greek-speaking Constantinople; disputes arose over church boundaries and control (for example, in Illyricum and Bulgaria). Rivalry developed in Slavic regions between Latin missionaries from the West and Byzantine missionaries from the East, who considered this territory to be Orthodox. Disputes over authority became even more heated in the 11th century as Rome asserted its primacy over all churches. Lesser matters related to worship and church discipline—for example, married clergy (Orthodox) versus celibacy (Roman Catholic) and rules of fasting and tonsure—strained ecclesial relations. The tensions became a schism in 1054, when the uncompromising patriarch of Constantinople, Michael Cerularius, and the uncompromising envoys of Pope Leo IX excommunicated each other. No act of separation was at this time considered final by either side. Total alienation came a century and a half later, as a result of the Crusades, when Christian knights made military campaigns to save Jerusalem and the Holy Land from the Muslims. In 1204 the Fourth Crusade was diverted to attack and capture Constantinople brutally. Thousands of Orthodox Christians were murdered; churches and icons were desecrated and undying hostility developed between East and West.
Even so, certain leaders and theologians on both sides tried to heal the breach and reunite East and West. In 1274, at the second Council of Lyon, agreement was reached between the two churches over several key issues—Orthodox acceptance of papal primacy and the acceptance of the Nicene Creed with the Filioque clause. But the agreements were only a rushed action conditioned by political intrigue. As a result, reunion on these terms was fiercely rejected by the clergy and laity in Constantinople and other Orthodox provinces. A second attempt at reunion came at the Council of Ferrara-Florence that met in Italy in 1438 and 1439. A formula of union was approved by both delegations, but later it was rejected by rank-and-file Orthodox Christians.
