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.
CONVERSION OF THE SLAVS
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.
FINAL EXTENSION OF ROMAN CATHOLICISM
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.
127. SEPARATION OF EASTERN AND WESTERN CHRISTIANITY
DIVERGENCE OF EAST AND WEST
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 PAPACY AND THE EASTERN EMPERORS
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.
