46 Eastern Christianity and Western Christianity
E. Eastern Christianity
One of the most influential acts of Constantine the Great was his decision in 330 to move the capital of the empire from Rome to “New Rome,” the city of Byzantium at the eastern end of the Mediterranean Sea. The new capital, Constantinople (now Istanbul), also became the intellectual and religious focus of Eastern Christianity. While Western Christianity became increasingly centralized, a pyramid the apex of which was the pope of Rome (see Papacy), the principal centers of the East—Constantinople, Jerusalem, Antioch, and Alexandria—developed autonomously. The emperor at Constantinople held a special place in the life of the church. It was he, for example, who convoked and presided over the general councils of the church, which were the supreme organ of ecclesiastical legislation in both faith and morals. This special relation between church and state, frequently (but with some oversimplification) called Caesaropapism, fostered a Christian culture in which (as the great Church of the Holy Wisdom at Constantinople, dedicated by Emperor Justinian in 538, attests) the noblest achievements of the entire society blended the elements of Christianity and of classical antiquity in a new synthesis.
At its worst, this culture could mean the subordination of the church to the tyranny of the state. The crisis of the 8th century over the legitimacy of the use of images in Christian churches was also a collision of the church and the imperial power. Emperor Leo III prohibited images, thus precipitating a struggle in which Eastern monks became the principal defenders of the icons. Eventually the icons were restored, and with them a measure of independence for the church (see Iconoclasm). During the 7th and 8th centuries three of the four Eastern centers were captured by the dynamic new faith of Islam, with only Constantinople remaining unconquered. It, too, was often besieged and finally fell to the Turks in 1453. The confrontation with the Muslims was not purely military, however. Eastern Christians and the followers of the Prophet Muhammad exerted influence on one another in intellectual, philosophical, scientific, and even theological matters.
The conflict over the images was so intense because it threatened the Eastern church at its most vital point—its liturgy. Eastern Christianity was, and still is, a way of worship and on that basis a way of life and a way of belief. The Greek word orthodoxy, together with its Slavic equivalent pravoslavie, refers to the correct form for giving praise to God, which is finally inseparable from the right way of confessing true doctrine about God and of living in accordance with the will of God. This emphasis gave to Eastern liturgy and theology a quality that Western observers, even in the Middle Ages, would characterize as mystical, a quality enhanced by the strongly Neoplatonic strain in Byzantine philosophy (see Neoplatonism).
