In spite of the hindrances to fusion, it seems true that the Germans and the Romans felt no great dislike for each other and that, as a rule, they freely intermingled. Certain conditions directly favored this result. First, many Germans had found their way within the empire as hired soldiers, colonists, and slaves, long before the invasions began. Second, the Germanic invaders came in relatively small numbers. Third, the Germans entered the Roman world not as destroyers, but as homeseekers. They felt a real reverence for Roman civilization. And fourth, some of the principal Germanic nations, including the Visigoths, Burgundians, and Vandals, were already Christians at the time of their invasions, while other nations, such as the Franks and the Anglo-Saxons, were afterwards converted to Christianity. As long, however, as most of the Germans remained Arian Christians [32] their belief stood in the way of friendly intercourse with the Roman provincials, who had accepted the Catholic faith.

If western Europe during the early Middle Ages presented a scene of violence and confusion while the Germans were settling in their new homes, a different picture was afforded by eastern Europe. Here the Roman Empire still survived and continued to uphold for centuries the Roman tradition of law and order. The history of that empire forms the theme of the following chapter.

The Roman Empire in the West moved rapidly to its "fall" in 476 A.D., at the hands of the Germanic invaders. The Roman Empire in the East, though threatened by enemies from without and weakened by civil conflicts from within, endured for more than a thousand years. Until the middle of the eleventh century it was the strongest state in Europe, except during the reign of Charlemagne, when the Frankish kingdom eclipsed it. Until the middle of the fifteenth century it preserved the name, the civilization, and some part of the dominions, of ancient Rome. [1]
The long life of the Roman Empire in the East is one of the marvels of history. Its great and constant vitality appears the more remarkable, when one considers that it had no easily defensible frontiers, contained many different races with little in common, and on all sides faced hostile states. The empire survived so long, because of its vast wealth and resources, its despotic, centralized government, the strength of its army, and the almost impregnable position occupied by Constantinople, the capital city.
The changing fortunes of the empire during the Middle Ages are reflected in some of the names by which it is often known. The term "Greek Empire" expresses the fact that the state became more and more Greek in character, owing to the loss, first of the western provinces in the fifth century, and then of Syria and Egypt in the seventh century. Another term— "Byzantine Empire"—appropriately describes the condition of the state in still later times, when its possessions were reduced to Constantinople (ancient Byzantium) and the territory in the neighborhood of that city. But through all this period the rulers at Constantinople regarded themselves as the true successors of Augustus, Diocletian, and Constantine. They never admitted the right of Charlemagne and Otto the Great to establish a rival Roman Empire in western Europe. [2] They claimed to be the only legitimate heirs of Old Rome.
The history of the Roman Empire in the East, for more than one hundred years after the death of Theodosius, is uneventful. His successors, though unable to prevent the Germans from seizing Italy and the other western provinces, managed to keep their own dominions intact. The eastern provinces escaped the fate of those in the West, because they were more populous and offered greater obstacles to the barbarian invaders, who followed the line of least resistance. The gradual recovery of the empire in strength and warlike energy prepared the way for a really eminent ruler—Justinian.
Justinian is described as a man of noble bearing, simple in his habits, affable in speech, and easy of approach to all his subjects. Historians have often drawn attention to his wonderful activity of mind and power of steady industry. So great was his zeal for work that one of his courtiers called him "the emperor who never sleeps." Possessed of large ideas and inspired by the majesty of Rome, Justinian aimed to be a great conqueror, a great lawgiver, and a great restorer of civilization. His success in whatever he undertook must be ascribed in part to his wife, Theodora, whom he associated with himself on the throne. Theodora, strong of mind and wise in counsel, made a worthy helpmate for Justinian, who more than once declared that in affairs of state he had consulted his "revered wife."
It was the ambition of Justinian to conquer the Germanic kingdoms which had been formed out of the Mediterranean provinces. In this task he relied chiefly on the military genius of Belisarius, one of the world's foremost commanders. Belisarius was able in one short campaign to destroy the Vandal kingdom in North Africa. [3] The Vandals by this time had lost their early vigor; they made but a feeble resistance; and their Roman subjects welcomed Belisarius as a deliverer. Justinian awarded a triumph to his victorious general, an honor which for five centuries emperors alone had enjoyed. The conquest of North Africa, together with the islands of Sardinia and Corsica, was followed by the overthrow of the Ostrogothic kingdom in Sicily and Italy. [4] Justinian also recovered from the Visigoths [5] the southeastern part of Spain. He could now say with truth that the Mediterranean was once more a Roman sea. [6]
[Illustration: A MOSAIC OF JUSTINIAN A mosaic dating from 547 A.D., in the church of San Vitale, Ravenna. It shows the emperor (in the center) with a bishop, his suite and imperial guards. The picture probably gives us a fair idea of Justinian's appearance, though it represents him as somewhat younger than he was at the time.]
The conquests of Justinian proved to be less enduring than his work as a lawgiver. Until his reign the sources of Roman law, including the legislation of the popular assemblies, the decrees of the Senate, the edicts of the of Roman praetors and emperors, and the decisions of learned lawyers, had never been completely collected and arranged in scientific form. Justinian appointed a commission of legal scholars to perform this task. The result of their labors, in which the emperor himself assisted, was the publication of theCorpus Juris Civilis, the "Body of Civil Law." Under this form the Roman principles of jurisprudence have become the foundation of the legal systems of modern Italy, Spain, France, Germany, and other European countries. These principles even influenced the Common law of England, which has been adopted by the United States. [7] TheCorpus Juris Civilis, because of this widespread influence, is justly regarded as one of Rome's most important gifts to the world.
Justinian's claim to the title of "Great" rests also on his civilizing work. He wished to restore the prosperity, as well as the provinces, of the empire. During his reign roads, bridges, and aqueducts were repaired, and commerce and agriculture were encouraged. It was at this time that two Christian missionaries brought from China the eggs of the silkworm, and introduced the manufacture of silk in Europe. As a builder Justinian gained special fame. The edifices which he caused to be raised throughout his dominions included massive fortifications on the exposed frontiers, splendid palaces, and many monasteries and churches. The most noteworthy monument to his piety is the church of Sancta Sophia [8] at Constantinople, now used as a Mohammedan mosque. By his conquests, his laws, and his buildings, Justinian revived for a time the waning glory of imperial Rome.
The Roman Empire in the East did not long remain at the pinnacle of greatness to which Justinian had raised it. His conquests, indeed, weakened rather than strengthened the empire, since now there were much more extensive frontiers to defend. Within half a century after his death it was attacked both in Europe and in Asia. The Lombards [9] soon seized Italy, and in the East the Persians renewed their contest against the Roman power.
[Illustration: Map, THE ROMAN EMPIRE IN THE EAST DURING THE TENTH ANDELEVENTH CENTURIES]
The struggle with the Persians was an inheritance from earlier times. [10] Under an ambitious king, Chosroes II, the Persians overran all the Asiatic provinces of the empire. A savior arose, however, in the person of the Roman emperor, Heraclius (610-641 A.D.). His brilliant campaigns against Chosroes partook of the nature of a crusade, or "holy war," for the Persians had violated the Holy Sepulcher at Jerusalem and had stolen away the True Cross, the most sacred relic of Christendom. Heraclius recovered all his provinces, but only at the cost of a bloody struggle which drained them of men and money and helped to make them fall easy victims to foes still more terrible than the Persians. These were the Arabs.
Heraclius had not closed his reign before he saw all his victories undone by the advance of the Arabs. The first wave of invasion tore away Syria and Egypt from the empire, penetrated Asia Minor, and reached the shores of the Bosporus. Repulsed before the walls of Constantinople, the Arabs carried their arms to the West and seized North Africa, Spain, part of southern Italy, and the Mediterranean islands. Asia Minor and the Balkan peninsula still held out, however, and during the tenth century a line of able rulers at Constantinople succeeded in winning back some of their lost provinces.
During the eleventh century the empire had to face new enemies. These were the Seljuk Turks, [11] fierce nomads from the steppes beyond the Caspian. After their conversion to Mohammedanism, they swept with irresistible force through the East and conquered nearly all Asia Minor. The ruin of this country, in earlier ages one of the most populous and flourishing regions of the world, dates from its occupation by the Seljuks. To resist their further advance the Roman emperor sought in 1095 A.D. the help of the Christians of Europe. His appeals for aid resulted in the First Crusade, with which a new chapter of medieval history began. (See Chapter XX.)
Thus, for more than five centuries after Justinian, the Roman Empire in the East was engaged in a long struggle with the foes—Persians, Arabs, and Seljuk Turks—which successively attacked its dominions. By its stubborn resistance of the advance of the invaders the old empire protected the young states of Europe from attack, until they grew strong enough to meet and repulse the hordes of Asia. This service to civilization was not less important than that which had been performed by Greece and Rome in their contests with the Persians and the Carthaginians.
The troubled years after Justinian's death also witnessed the beginning of the Slavic [12] settlements in southeastern Europe. The Slavs belonged to the Indo-European race, but had not progressed in civilization as far as the Germans. Their cradle land seems to have been in western Russia, whence they slowly spread to the Baltic, the Elbe, and the Danube. We have already mentioned the campaigns which Charlemagne and Henry the Fowler waged against them. [13] The emperors at Constantinople were less successful in resisting that branch of the Slavs which tried to occupy the Balkan peninsula. After crossing the Danube, the Slavs pressed on farther and farther, until they reached the southern extremity of ancient Greece. They avoided the cities, but formed peasant communities in the open country, where they readily mingled with the inhabitants. Their descendants have remained in the Balkan peninsula to this day. The inhabitants of modern Serbia [14] are Slavs, and even in the Greeks there is a considerable strain of Slavic blood.
The Bulgarians, a people akin to the Huns and Avars, made their appearance south of the lower Danube in the seventh century. For more than three hundred years these barbarians, brutal, fierce, and cruel, were a menace to the empire. At one time they threatened Constantinople and even killed a Roman emperor, whose skull was converted into a drinking cup to grace their feasts. The Bulgarians settled in the region which now bears their name and gradually adopted the speech and customs of the Slavs. Modern Bulgaria is essentially a Slavic state.
The empire was attacked in southeastern Europe by still other barbarians, among whom were the Russians. This Slavic people, led by chieftains from Sweden, descended the Dnieper and Dniester rivers and, crossing the Black Sea, appeared before the walls of Constantinople. Already, in the tenth century, that city formed the goal of Russian ambitions. The invaders are said to have made four attempts to plunder its treasures. Though unsuccessful, they compelled the emperors from time to time to pay them tribute.
Christianity reached the invaders of the Balkan peninsula from Constantinople. The Serbians, Bulgarians, and Russians were converted in the ninth and tenth centuries. With Christianity they received the use of letters and some knowledge of Roman law and methods of government. Constantinople was to them, henceforth, such a center of religion and culture as Rome was to the Germans. By becoming the teacher of the vast Slavic peoples of the Balkan peninsula and European Russia, the empire performed another important service to civilization.
The Roman Empire in the East, though often menaced by barbarian foes, long continued to be the leading European power. Its highest degree of prosperity was reached between the middle of the ninth and the middle of the eleventh century. The provinces in Asia Minor and the Balkan peninsula produced a vast annual revenue, much of which went for defense. It was necessary to maintain a large, well-disciplined army, great fleets and engines of war, and the extensive fortifications of Constantinople and the frontier cities. Confronted by so many dangers, the empire could hope to survive only by making itself a strong military state.
The merchant ships of Constantinople, during the earlier part of the Middle Ages, carried on most of the commerce of the Mediterranean and the Black Sea. The products of Byzantine industry, including silks, embroideries, mosaics, enamels, and metal work, were exchanged at that city for the spices, drugs, and precious stones of the East. Byzantine wares also found their way into Italy and France and, by way of the Russian rivers, reached the heart of eastern Europe. Russia, in turn, furnished Constantinople with large quantities of honey, wax, fur, wool, grain, and slaves. A traveler of the twelfth century well described the city as a metropolis "common to all the world, without distinction of country or religion."
Many of the Roman emperors from Justinian onward were great builders. Byzantine architecture, seen especially in the churches, became a leading form of art. Its most striking feature is the dome, which replaces the flat, wooden roof used in the basilican [15] Churches of Italy. The exterior of a Byzantine church is plain and unimposing, but the interior is adorned on a magnificent scale. The eyes of the worshiper are dazzled by the walls faced with marble slabs of variegated colors, by the columns of polished marble, jasper, and porphyry, and by the brilliant mosaic pictures of gilded glass. The entire impression is one of richness and splendor. Byzantine artists, though mediocre painters and sculptors, excelled in all kinds of decorative work. Their carvings in wood, ivory, and metal, together with their embroideries, enamels, and miniatures, enjoyed a high reputation throughout medieval Europe.
Byzantine art, from the sixth century to the present time, has exerted a wide influence. Sicily, southern Italy, Rome, Ravenna, and Venice contain many examples of Byzantine churches. Italian painting in the Middle Ages seems to have been derived directly from the mosaic pictures of the artists of Constantinople. Russia received not only its religion but also its art from Constantinople. The great Russian churches of Moscow and Petrograd follow Byzantine models. Even the Arabs, in spite of their hostility to Christianity, borrowed Byzantine artists and profited by their services. The Mohammedan mosques of Damascus, Cairo, and Cordova, both in methods of construction and in details of ornamentation, reproduce Byzantine styles.
The libraries and museums of Constantinople preserved classical learning. In the flourishing schools of that city the wisest men of the day taught philosophy, law, medicine, and science to thousands of students. The professors figured among the important persons of the court: official documents mention the "prince of the rhetoricians" and the "consul of the philosophers." Many of the emperors showed a taste for scholarship; one of them was said to have been so devoted to study that he almost forgot to reign. When kings in western Europe were so ignorant that they could with difficulty scrawl their names, eastern emperors wrote books and composed poetry. It is true that Byzantine scholars were erudite rather than original. Impressed by the great treasures of knowledge about them, they found it difficult to strike out into new, unbeaten paths. Most students were content to make huge collections of extracts and notes from the books which antiquity had bequeathed to them. Even this task was useful, however, for their encyclopedias preserved much information which otherwise would have been lost. During the Middle Ages the East cherished the productions of classical learning, until the time came when the West was ready to receive them and to profit by them.
The heart of Byzantine civilization was Constantinople. The city lies on a peninsula between the Sea of Marmora and the spacious harbor called the Golden Horn. Washed on three sides by the water and, like Rome, enthroned upon seven hills, Constantinople occupies a site justly celebrated as the noblest in the world. It stands in Europe, looks on Asia, and commands the entrance to both the Mediterranean and the Black Sea. As a sixteenth century writer pointed out, Constantinople "is a city which Nature herself has designed to be the mistress of the world."
[Illustration: Map, VICINITY OF CONSTANTINOPLE]
The position of Constantinople made it difficult to attack but easy to defend. To surround the city an enemy would have to be strong upon both land and sea. A hostile army, advancing through Asia Minor, found its further advance arrested by the long, winding channel which the Bosporus, the Sea of Marmora, and the Dardanelles combine to form. A hostile fleet, coming by way of the Mediterranean or the Black Sea, faced grave difficulties in attempting to penetrate the narrow strait into which this waterway contracts at each extremity. On the landward side the line of defense was so short—about four miles in width—that it could be strongly fortified and held by a small force against large numbers. During the Middle Ages the rear of the city was protected by two huge walls, the remains of which are still visible. Constantinople, in fact, was all but impregnable. Though each new century brought a fresh horde of enemies, it resisted siege after siege and long continued to be the capital of what was left of the Roman Empire. [16]
Constantine had laid out his new city on an imposing scale and adorned it with the choicest treasures of art from Greece, Italy, and the Orient. Fourteen churches, fourteen palaces, eight public baths, and several triumphal arches are assigned to the founder of the city. His most stately building was the Hippodrome, an immense structure devoted to chariot races and all sorts of popular gatherings. There new emperors, after their consecration in Sancta Sophia, were greeted by their subjects; there civic festivals were held; and there the last Roman triumphs were celebrated. Theodosius the Great built the principal gate of Constantinople, the "Golden Gate," as it was called, by which the emperors made their solemn entry into the city. But it was Justinian who, after Constantine, did most to adorn the new capital by the Bosporus. He is said to have erected more than twenty-five churches in Constantinople and its suburbs. Of these, the most beautiful is the world-famed cathedral dedicated by Justinian to "Holy Wisdom." On its completion the emperor declared that he had surpassed Solomon's Temple. Though nearly fourteen hundred years old and now defaced by vandal hands, it remains perhaps the supreme achievement of Christian architecture.
[Illustration: SANCTA SOPHIA, CONSTANTINOPLE Built by Justinian and dedicated on Christmas Day, 538 A.D. The main building is roofed over by a great central dome 107 feet in diameter and 179 feet in height. After the Ottoman Turks turned the church into a mosque, a minaret was erected at each of the four exterior angles. The outside of Sancta Sophia is somewhat disappointing, but the interior, with its walls and columns of polished marble granite and porphyry, is magnificent. The crystal balustrades, pulpits, and large metal disks are Turkish.]

[Illustration: Map, CONSTANTINOPLE]
Excepting Athens and Rome, no other European city can lay claim to so long and so important a history as Constantinople. Her day came after theirs was done. Throughout the Middle Ages Constantinople remained the most important city in Europe. When London, Paris, and Vienna were small and mean towns, Constantinople was a large and flourishing metropolis. The renown of the city penetrated even into barbarian lands. The Scandinavians called it Micklegarth, the "Great City"; the Russians knew of it as Tsarigrad, the "City of the Caesars." But its own people best described it as the "City guarded by God." Here, for more than eleven centuries, was the capital of the Roman Empire and the center of Eastern Christendom.

A preceding chapter has traced the early history of Christianity. We there saw how the new religion appeared in the Orient, how it spread rapidly over the Roman Empire, how it engaged with the imperial government in the long conflict called the Persecutions, how the emperor Constantine, after his conversion, placed it on an equality with paganism, and how at the end of the fourth century the emperor Theodosius made it the state religion. By this time the Church had become a great and powerful organization, with fixed laws, with a graded system of officers, and with councils attended by clergy from all parts of the Roman world. To this organization the word Catholic, that is, "universal," came to be applied. Membership in the Catholic Church, secured only by baptism, was believed to be essential to salvation. As St. Cyprian, bishop of Carthage, had said, "He can no longer have God for his Father who has not the Church for his Mother."
The first three centuries of Christianity witnessed the development of the episcopal system in the Church. Each provincial city had its bishop, assisted by priests and deacons. An archbishop (sometimes called a metropolitan) presided over the bishops of each province, and a patriarch had jurisdiction, in turn, over metropolitans. This graded arrangement of ecclesiastical officers, from the lowest to the highest, helped to make the Church centralized and strong. It appears to have been modeled, almost unconsciously, on the government of the Roman Empire. [2]
The development of the patriarchate calls for special notice. At the time of the Council of Nicaea [3] there were three patriarchs, namely, the bishops of Rome, Antioch, and Alexandria. These cities ranked among the most important in the Roman world. It was only natural, therefore, that the churches established in them should be singled out for preëminence. Some years after the removal of the capital to Constantinople, the bishop of that imperial city was recognized as a patriarch at a general council of the Church. In the fifth century the bishop of Jerusalem received the same dignity. Henceforth there were five patriarchs—four in the East but only one in the West.
The Christian Church was a very democratic organization. Patriarchs, archbishops, bishops, priests, and deacons were drawn from all ranks of life. No special training at first was considered necessary to fit them for their duties, though the more celebrated ministers were often highly educated. To eke out their salaries the clergy sometimes carried on business as farmers and shopkeepers. Where, however, a church had sufficient funds to support its bishop, his engagement in secular affairs was discouraged and finally prohibited. In the fourth century, as earlier, priests and bishops were generally married men. The sentiment in favor of celibacy for the clergy became very pronounced during the early Middle Ages, especially in the West, and led at length to the general abandonment of priestly marriage in those parts of Europe where papal influence prevailed. Distinctive garments for clergymen did not begin to come into use until the fifth century, when some of them began to don clothing of a more sober hue than was fashionable at the time. Clerical vestments were developed from two pieces of ancient Roman dress—the tunic and the toga. [4] Thus the clergy were gradually separated from the people, or laity, by differences in dress, by their celibate lives, and by their abstention from worldly occupations.
While the Church was perfecting her organization, she was also elaborating her doctrines. Theologians engaged in many controversies upon such subjects as the connection of Christ with God and the nature of the Trinity. In order to obtain an authoritative expression of Christian opinion, councils of the higher clergy were held, at which the opposing views were debated and a decision was reached. The Council of Nicaea, which condemned Arianism, formed the first, and one of the most important, of these general gatherings of the Church. After the Church had once expressed itself on any matter of Christian belief, it was regarded as unlawful to maintain a contrary opinion. Those who did so were called heretics, and their teachings, heresies. The emperor Theodosius, whose severe laws finally shattered the ancient paganism, [5] devoted even more attention to stamping out heresies among his Christian subjects. He prohibited meetings of heretics, burned their books, and threatened them with death if they persisted in their peculiar doctrines. During his reign a Spanish bishop and six of his partisans were executed for holding unorthodox beliefs. This was the beginning of the persecutions for heresy.
As soon as Christianity had triumphed in the Roman Empire, thus becoming the religion of the rich and powerful as well as the religion of the poor and lowly, more attention was devoted to the conduct of worship. Magnificent church buildings were often erected. Their architects seem to have followed as models the basilicas, or public halls, which formed so familiar a sight in Roman cities. [6] Church interiors were adorned with paintings, mosaic pictures, images of saints and martyrs, and the figure of the cross. Lighted candles on the altars and the burning of fragrant incense lent an additional impressiveness to worship. Beautiful prayers and hymns were composed. Some of the early Christian hymns, such as theGloria in Excelsisand theTe Deum Laudamus, are still sung in our churches. Organs did not come into use until the seventh century, and then only in the West, but church bells, summoning the worshiper to divine service, early became attached to Christian edifices.
[Illustration: RELIGIOUS MUSIC From a window of the cathedral of Bourges, a city in central France. Shows a pipe organ and chimes.]
The Christians from the start appear to have observed "the first day of the week" [7] in memory of Christ's resurrection. They attended public worship on the Lord's Day, but otherwise did not rigidly abstain from worldly business and amusements. The Jewish element in some churches, and especially in the East, was strong enough to secure an additional observance of Saturday as a weekly festival. Saturday long continued to be marked by religious assemblies and feasting, though not by any compulsory cessation of the ordinary occupations. During the fourth century Sunday, as the Lord's Day was now generally called, came more and more to be kept as a day of obligatory rest. Constantine's Sunday law [8] formed the first of a long series of imperial edicts imposing the observance of that day as a legal duty. In this manner Sunday, like the Jewish Sabbath on the seventh day of the week, was dedicated wholly to the exercises of religion.
The great yearly festivals of the Church gradually took shape during the early Christian centuries. The most important anniversary to be observed was Easter, in memory of the resurrection of Christ. A period of fasting (Lent), which finally lasted forty days, preceded the festival. Whitsunday, or Pentecost, was celebrated on the fiftieth day after Easter. [9] Two other festivals of later adoption were Christmas, the celebration of which was finally assigned to the 25th of December, [10] and Epiphany (January 6), commemorating the baptism of Christ. In course of time many other feasts and fasts, together with numerous saints' days, were added to the calendar of the "Christian Year."
By the time of Constantine, Christianity had spread widely throughout the eastern half of the Roman Empire. Asia Minor was then largely Christian. Thrace, Macedonia, Epirus, and Greece were all ecclesiastical provinces with their own metropolitans. Many Christians were found in Syria and Egypt. Churches also existed in Mesopotamia and Arabia, and even beyond the boundaries of the empire in Armenia and Persia. Between the time of Constantine and that of Justinian, Christianity continued to expand in the East, until the gospel had been carried to such distant regions as Abyssinia and India.
Most of the Christian communities in the Orient owed allegiance to the patriarchs of Constantinople, Jerusalem, Antioch, and Alexandria. The Roman emperor, however, was the supreme religious authority in the East. He felt it as much his duty to maintain the doctrines and organization of Christianity as to preserve the imperial dominions against foreign foes. Since he presided over the Church, there could be no real independence for its officers. Bishops, metropolitans, and patriarchs were in every respect subordinate to his will. This union of Church and State formed one of the most characteristic features of Christianity in the East.
Eastern Christians, far more than those in the West, devoted themselves to theological speculations. Constantinople and the great Hellenistic cities of Antioch and Alexandria contained many learned scholars who had prolonged and heated arguments over subtle questions of belief. After the Arian controversy had been settled in the fourth century, other disputes concerning the true nature of Christ broke out. These gave rise to many heresies.
The heresy known as Nestorianism, from Nestorius, a patriarch of Constantinople, spread widely in the East. Nestorian missionaries even penetrated to India, China, and Mongolia. The churches which they established were numerous and influential during the Middle Ages, but since then most of them have been destroyed by the Mohammedans. Members of this sect are still to be found, however, in eastern lands. [11]
[Illustration: THE NESTORIAN MONUMENT Evidence of Nestorian missions in China is afforded by the famous monument at Chang-an, province of Shensi. The stone, which was set up in 781 A.D., commemorates by an inscription in Chinese characters and the figure of a cross the introduction of Christianity into northwestern China. A replica of the Nestorian monument was taken to the United States in 1908 A.D. and was deposited in the Metropolitan Museum of Art, New York.]
After the formation of the Nestorian and other heretical sects, the orthodox faith was preserved in the East only by the Greeks of Asia Minor and Europe. The Greek Church, which calls itself the "Holy Orthodox Church," for a time remained in unity with the Roman Church in the West. The final separation of these two churches occurred in the eleventh century. [12]
Christianity in the West presented two sharp contrasts to eastern Christianity. In the first place, the great heresies which divided the East scarcely affected the West. In the second place, no union of Church and State existed among western Christians. Instead of acknowledging the religious supremacy of the emperor at Constantinople, they yielded obedience to the bishop of Rome, the head of the Roman Church. He is known to us as the pope, and his office is called the Papacy. We shall now inquire how the popes secured their unchallenged authority over western Christendom.
[Illustration: PAPAL ARMS According to the well-known passage inMatthew(xvi, 19), Christ gave to St. Peter the "keys of the kingdom of heaven," with the power "to bind and to loose." These keys are always represented in the papal arms, together with the tiara or headdress, worn by the popes on certain occasions.]
A church in Rome must have been established at an early date, for it was to Roman Christians that St. Paul addressed one of theEpistlesnow preserved in the New Testament. St. Paul visited Rome, as we know from theActs of the Apostles, and there he is said to have suffered martyrdom. Christian tradition, very ancient and very generally received, declares that St. Peter also labored in Rome, where he met a martyr's death, perhaps during the reign of the emperor Nero. To the early Christians, therefore, the Roman Church must have seemed in the highest degree sacred, for it had been founded by the two greatest apostles and had been nourished by their blood.
Another circumstance helped to give the Roman Church a superior position in the West. It was a vigorous missionary church. Rome, the largest and most flourishing city in the empire and the seat of the imperial government, naturally became the center from which Christianity spread over the western provinces. Many of the early Christian communities planted in Spain, Gaul, and Africa owed their start to the missionary zeal of the Roman Church. To Rome, as the great "Mother-church," her daughters in western Europe would turn henceforth with reverence and affection; they would readily acknowledge her leading place among the churches; and they would seek her advice on disputed points of Christian belief or worship.
The independence of the Roman Church also furthered its development. The bishop of Rome was the sole patriarch in the West, while in the East there were two, and later four patriarchs, each exercising authority in religious matters. Furthermore, the removal of the capital from Rome to Constantinople helped to free the Roman bishop from the close oversight of the imperial government. He was able, henceforth, to promote the interests of the church under his control without much interference on the part of the eastern emperor.
Finally, it must be noted how much the development of the Roman Church was aided by its attitude on disputed questions of belief. While eastern Christendom was torn by theological controversies, the Church of Rome stood firmly by the Nicene Creed. [13] After the Arian, Nestorian, and other heresies were finally condemned, orthodox Christians felt indebted to the Roman Church for its unwavering championship of "the faith once delivered to the saints." They were all the more ready, therefore, to defer to that church in matters of doctrine and to accept without question its spiritual authority.
The claim of the Roman bishops to supremacy over the Christian world had a double basis. Certain passages in the New Testament, where St. Peter is represented as the rock on which the Church is built, the pastor of the sheep and lambs of the Lord, and the doorkeeper of the kingdom of heaven, appear to indicate that he was regarded by Christ as the chief of the Apostles. Furthermore, a well-established tradition made St. Peter the founder of the Roman Church and its first bishop. It was then argued that he passed to his successors, the popes, all his rights and dignity. As St. Peter was the first among the Apostles, so the popes were to be the first among bishops. Such was the doctrine of the Petrine supremacy, expressed as far back as the second century, strongly asserted by many popes during the Middle Ages, and maintained to-day by the Roman Church.
Up to the middle of the fifth century about forty-five bishops had occupied St. Peter's chair at Rome. The most eminent these was Leo the Great. When he became bishop, the Germans were overrunning the western provinces of the empire. The invaders professed the Arian faith, as we have seen, and often persecuted the orthodox Christians among whom they settled. At such a time, when the imperial power was growing weaker, faithful Catholics in the West naturally turned for support to the bishop of Rome. Leo became their champion against the barbarians. Tradition declares that he succeeded in diverting Attila from an attack on Rome, and when the Vandals sacked the city Leo also intervened to prevent its destruction. [14]
After Leo, no important name occurs in the list of popes until we come to Gregory the Great. Gregory, as the son of a rich and distinguished Roman senator, enjoyed a good education in all the learning of the time. He entered public life and at an early age became prefect of Rome. But now, almost at the outset of his career, Gregory laid aside earthly ambition. He gave up his honorable position and spent the fortune, inherited from his father, in the foundation of monasteries and the relief of the poor. He himself became a monk, turned his palace at Rome into a monastery, and almost ruined his health by too great devotion to fasts and midnight vigils. Gregory's conspicuous talents, however, soon called him from retirement and led to his election as pope.
The work of Gregory lay principally in two directions. As a statesman he did much to make the popes virtual sovereigns at Rome and in Italy. At this time the Italian peninsula, overrun by the Lombards and neglected by the eastern emperor, was in a deplorable condition. The bishop of Rome seemed to be the only man who could protect the people and maintain order. Gregory had very great success in this task. He appointed governors of cities, issued orders to generals, drilled the Romans for military defense, and sent ambassadors to treat with the king of the Lombards. It was largely owing to Gregory's efforts that these barbarians were prevented from conquering central Italy.
Gregory was no less eminent as a churchman. His writings and his personal influence greatly furthered the advancement of the Roman Church in the West. We find him sternly repressing heresies wherever they arose, aiding the conversion of Arian Visigoths in Spain and Arian Lombards in Italy, and sending out monks as missionaries to distant Britain. [15] He well deserved by these labors the title "Servant of the servants of God," [16] which he assumed, and which the popes after him have retained. The admiration felt for his character and abilities raised him, in later ages, to the rank of a saint.
When Gregory the Great closed his remarkable career, the Papacy had reached a commanding place in western Christendom. To their spiritual authority the popes had now begun to add some measure of temporal power as rulers at Rome and in Italy. During the eighth century, as we have already learned, [17] the alliance of the popes and the Franks helped further to establish the Papacy as an ecclesiastical monarchy, ruling over both the souls and bodies of men. Henceforth it was to go forward from strength to strength.
The Papacy during the Middle Ages found its strongest supporters among the monks. By the time of Gregory the Great monasticism [18] was well established in the Christian Church. Its origin must be sought in the need, often felt by spiritually-minded men, of withdrawing from the world —from its temptations and its transitory pleasures—to a life of solitude, prayer, and religious contemplation. Joined to this feeling has been the conviction that the soul may be purified by subduing the desires and passions of the body. Men, influenced by the monastic spirit, sought a closer approach to God.
The monastic spirit in Christianity owed much to the example of its founder, who was himself unmarried, poor, and without a place "where to lay his head." Some of Christ's teachings, taken literally, also helped to exalt the worth of the monastic life. At a very early period there were Christian men and women who abstained from marriage, flesh meat, and the use of wine, and gave themselves up to prayer, religious exercises, and works of charity. This they did in their homes, without abandoning their families and human society.
Another monastic movement began about the middle of the third century, when many Christians in Egypt withdrew into the desert to live as hermits. St. Anthony, who has been called the first Christian hermit, passed twenty years in a deserted fort on the east bank of the Nile. During all this time he never saw a human face. Some of the hermits, believing that pain and suffering had a spiritual value, went to extremes of self- mortification. They dwelt in wells, tombs, and on the summits of pillars, deprived themselves of necessary food and sleep, wore no clothing, and neglected to bathe or to care for the body in any way. Other hermits, who did not practice such austerities, spent all day or all night in prayer. The examples of these recluses found many imitators in Syria and other eastern lands. [19]
[Illustration: ST. DANIEL THE STYLITE ON HIS COLUMNFrom a Byzantine miniature in the Vatican.]
A life shut off from all contact with one's fellows is difficult and beyond the strength of ordinary men. The mere human need for social intercourse gradually brought the hermits together, at first in small groups and then in larger communities, or monasteries. The next step was to give the scattered monasteries a common organization and government. Those in the East gradually adopted the regulations which St. Basil, a leading churchman of the fourth century, drew up for the guidance of the monks under his direction. St. Basil's Rule, as it is called, has remained to the present time the basis of monasticism in the Greek Church.
The monastic system, which early gained an entrance into western Christendom, looked to St. Benedict as its organizer. While yet a young man, St. Benedict had sought to escape from the vice about him by retiring to a cave in the Sabine hills near Rome. Here he lived for three years as a hermit, shutting himself off from all human intercourse, wearing a hair shirt, and rolling in beds of thistles to subdue "the flesh." St. Benedict's experience of the hermit's life convinced him that there was a surer and better road to religious peace of mind. His fame as a holy man had attracted to him many disciples, and these he now began to group in monastic communities under his own supervision. St. Benedict's most important monastery was at Monte Cassino, midway between Rome and Naples. It became the capital of monasticism in the West.
[Illustration: PLAN OF KIRKSTALL ABBEY, YORKSHIRE]
To control the monks of Monte Cassino St. Benedict framed a Rule, or constitution, which was modeled in some respects upon the earlier Rule of St. Basil. The monks formed a sort of corporation, presided over by an abbot, [20] who held office for life. To the abbot every candidate for admission took the vow of obedience. Any man, rich or poor, noble or peasant, might enter the monastery, after a year's probation; having once joined, however, he must remain a monk for the rest of his days. The monks were to live under strict discipline. They could not own any property; they could not go beyond the monastery walls without the abbot's consent; they could not even receive letters from home; and they were sent to bed early. A violation of the regulations brought punishment in the shape of private admonitions, exclusion from common prayer, and, in extreme cases, expulsion.
The Rule of St. Benedict came to have the same wide influence in the West which that of St. Basil exerted in the East. Gregory the Great established it in many places in Italy, Sicily, and England. During Charlemagne's reign it was made the only form of monasticism throughout his dominions. By the tenth century the Rule prevailed everywhere in western Europe. [21]
St. Benedict sought to draw a sharp line between the monastic life and that of the outside world. Hence he required that, as far as possible, each monastery should form an independent, self-supporting community whose members had no need of going beyond its limits for anything. In course of time, as a monastery increased in wealth and number of inmates, it might come to form an enormous establishment, covering many acres and presenting within its massive walls the appearance of a fortified town.
The principal buildings of a Benedictine monastery of the larger sort were grouped around an inner court, called a cloister. These included a church, a refectory, or dining room, with the kitchen and buttery near it, a dormitory, where the monks slept, and a chapter house, where they transacted business. There was also a library, a school, a hospital, and a guest house for the reception of strangers, besides barns, bakeries, laundries, workshops, and storerooms for provisions. Beyond these buildings lay vegetable gardens, orchards, grain fields, and often a mill, if the monastery was built on a stream. The high wall and ditch, usually surrounding a monastery, shut it off from outsiders and in time of danger protected it against attack.
[Illustration: ABBEY OF SAINT GERMAIN DES PRÉS, PARIS This celebrated monastery was founded in the sixth century. Of the original buildings only the abbey church remains. The illustration shows the monastery as it was in 1361 A.D., with walls, towers, drawbridge, and moat. Adjoining the church were the cloister, the refectory, and the dormitory.]
St. Benedict defined a monastery as "a school for the service of the Lord." The monks under his Rule occupied themselves with a regular round of worship, reading, and manual labor. Each day was divided into seven sacred offices, beginning and ending with services in the monastery church. The first service came usually about two o'clock in the morning; the last, just as evening set in, before the monks retired to rest. In addition to their attendance at church, the monks spent several hours in reading from the Bible, private prayer, and meditation. For most of the day, however, they worked hard with their hands, doing the necessary washing and cooking for the monastery, raising the necessary supplies of vegetables and grain, and performing all the other tasks required to maintain a large establishment. This emphasis on labor, as a religious duty, was a characteristic feature of western monasticism. "To labor is to pray" became a favorite motto of the Benedictines. [22]
[Illustration: A MONK COPYISTFrom a manuscript in the British Museum, London.]
It is clear that life in a Benedictine monastery appealed to many different kinds of people in the Middle Ages. Those of a spiritual turn of mind found in the monastic life the opportunity of giving themselves wholly to God. Studious and thoughtful persons, with no disposition for an active career in the world, naturally turned to the monastery as a secure retreat. The friendless and the disgraced often took refuge within its walls. Many a troubled soul, to whom the trials of this world seemed unendurable, sought to escape from them by seeking the peaceful shelter of the cloister.
The civilizing influence of the Benedictine monks during the early Middle Ages can scarcely be over-emphasized. A monastery was often at once a model farm, an inn, a hospital, a school, and a library. By the careful cultivation of their lands the monks set an example of good farming wherever they settled. They entertained pilgrims and travelers, at a period when western Europe was almost destitute of inns. They performed many works of charity, feeding the hungry, healing the sick who were brought to their doors, and distributing their medicines freely to those who needed them. In their schools they trained both boys who wished to become priests and those who intended to lead active lives in the world. The monks, too, were the only scholars of the age. By copying the manuscripts of classical authors, they preserved valuable books that would otherwise have been lost. By keeping records of the most striking events of their time, they acted as chroniclers of medieval history. To all these services must be added the work of the monks as missionaries to the heathen peoples of Europe.
Almost all Europe had been won to Christianity by the end of the eleventh century. In the direction of this great missionary campaign the Roman Church took the leading part. [23] The officers of her armies were zealous popes, bishops, and abbots; her private soldiers were equally zealous monks, priests, and laymen. Pagan Rome had never succeeded in making a complete and permanent conquest of the barbarians. Christian Rome, however, was able to bring them all under her spiritual sway.
Christianity first reached the Germanic invaders in its Arian [24] form. Visigoths, Ostrogoths, Vandals, Burgundians, and Lombards were all Arians. The Roman Church regarded them as heretics and labored with success to reconvert them. This work was at last completed when the Lombards, in the seventh century, accepted the Catholic faith.
The Franks and the Anglo-Saxons, whose kingdoms were to develop into the chief states of medieval Europe, adopted from the outset the Catholic form of Christianity. The conversion of the Franks provided the Roman Church with its strongest and most faithful adherents among the Germanic tribes. [25] The conversion of Anglo-Saxon Britain by Augustine and his monks, followed later by the spread of Roman Catholicism in Ireland and Scotland, firmly united the British Isles to the Papacy. [26] Thus Rome during the Middle Ages came to be the one center of church life for the peoples of western Europe.
An Anglo-Saxon monk, St. Boniface, did more than any other missionary to carry Christianity to the remote tribes of Germany. Like Augustine in England, St. Boniface was sent by the pope, who created him missionary bishop and ordered him to "carry the word of God to unbelievers." St. Boniface also enjoyed the support of the Frankish rulers, Charles Martel and Pepin the Short. Thanks to their assistance this intrepid monk was able to penetrate into the heart of Germany. Here he labored for nearly forty years, preaching, baptizing, and founding numerous churches, monasteries, and schools. His boldness in attacking heathenism is illustrated by the story of how he cut down with his own hands a certain oak tree, much reverenced by the natives of Hesse as sacred to the god Woden, and out of its wood built a chapel dedicated to St. Peter. St. Boniface crowned a lifetime of missionary labor with a martyr's death, probably in 754 A.D. His work was continued by Charlemagne, who forced the Saxons to accept Christianity at the point of the sword. [27] All Germany at length became a Christian land, devoted to the Papacy.
Roman Catholicism not only spread to Celtic and Germanic peoples, but it also gained a foothold among the Slavs. Both Henry the Fowler and Otto the Great attempted to Christianize the Slavic tribes between the Elbe of the Slavs and the Vistula, by locating bishoprics in their territory. The work of conversion encountered many setbacks and did not reach completion until the middle of the twelfth century. The most eminent missionaries to the Slavs were Cyril and Methodius. These brother-monks were sent from Constantinople in 863 A.D. to convert the Moravians, who formed a kingdom on the eastern boundary of Germany. Seeing their great success as missionaries, the pope invited them to Rome and secured their consent to an arrangement which brought the Moravian Christians under the control of the Papacy. [28] From Moravia Christianity penetrated into Bohemia and Poland. These countries still remain strongholds of the Roman Church. The Serbians and Russians, as we have learned, [29] received Christianity by way of Constantinople and so became adherents of the Greek Church.
Roman Catholicism gradually spread to most of the remaining peoples of Europe. The conversion of the Norwegians and Swedes was well advanced by the middle of the eleventh century. The Magyars, or Hungarians, accepted Christianity at about the same date. The king of Hungary was such a devout Catholic that in the year 1000 A.D. the pope sent to him a golden crown and saluted him as "His Apostolic Majesty." The last parts of heathen Europe to receive the message of the gospel were the districts south and east of the Baltic, occupied by the Prussians, Lithuanians, and Finns. Their conversion took place between the twelfth and fourteenth centuries.
Before the Christian conquest of Europe was finished, Christianity had divided into two great communions—the Greek Church and the Roman Church. Their separation was a long, slow process, arising from the deep-seated differences between East and West. Though Rome had carried her conquering arms throughout the Mediterranean basin, all the region east of the Adriatic was imperfectly Romanized. [30] It remained Greek in language and culture, and tended, as time went on, to grow more and more unlike the West, which was truly Roman. The founding of Constantinople and the transference of the capital from the banks of the Tiber to the shores of the Bosporus still further widened the breach between the two halves of the Roman world. After the Germans established their kingdoms in Italy, Spain, Gaul, and Britain, western Europe was practically independent of the rulers at Constantinople. The coronation of Charlemagne in 800 A.D. marked the final severance of East and West.
The division of the Roman Empire led naturally to a grouping of the Christian Church about Rome and Constantinople, the two chief centers of government. The popes, it has been seen, had always enjoyed spiritual leadership in the West. In temporal matters they acknowledged the authority of the eastern emperors, until the failure of the latter to protect Rome and Italy from the barbarians showed clearly that the popes must rely on their own efforts to defend Christian civilization. We have already learned how well such men as Leo the Great and Gregory the Great performed this task. Then in the eighth century came the alliance with the Frankish king, Pepin the Short, which gave the Papacy a powerful and generous protector beyond the Alps. Finally, by crowning Charlemagne, the pope definitely broke with the emperor at Constantinople and transferred his allegiance to the newly created western emperor.
The patriarch of Constantinople, as bishop of the capital city, enjoyed an excellent position from which to assert his preeminence over the bishops of the other churches in the East. Justinian in 550 A.D. conferred on him the privilege of receiving appeals from the other patriarchs, and a few years later that dignitary assumed the high-sounding title of "Universal Archbishop." The authority of the patriarch of Constantinople was immensely strengthened when the Mohammedans, having conquered Syria and Egypt, practically extinguished the three patriarchates of Antioch, Jerusalem, and Alexandria. [31] The Church in the East now had a single patriarch, just as that in the West had the one bishop of Rome. Rivalry between them was inevitable.
