Period III. The Dissolution Of The Imperial State Church And The Transition To The Middle Ages: From The Beginning Of The Sixth Century To The Latter Part Of The Eighth

The third period of the ancient Church under the Christian Empire begins with the accession of Justin I (518-527), and the end of the first schism between Rome and Constantinople (519). The termination of the period is not so clearly marked. By the middle and latter part of the eighth century, however, the imperial Church has ceased to exist in its original conception. The Church in the East has become, in great part, a group of national schismatic churches under Moslem rulers, and only the largest fragment of the Church of the East is the State Church of the greatly reduced Eastern empire. In the West, the imperial influence has ceased, and the Roman see has allied its fortunes with the rising Frankish power, and the rise of a Western empire is already foreshadowed.

In this period, the imperial ecclesiastical system, which had begun with Constantine, found its completion in the Cæsaropapism which was definitively established by Justinian as the constitution of the Eastern Church. But at the same time the Monophysite churches seceded and became permanent national churches. The long Christological controversy found, at least as regards Monophysitism, its settlement on a basis derived from the revived Aristotelian philosophy; and the mystical piety of the East, with its apparatus [pg 539] of hierarchy and sacraments, found its characteristic expression in the works of Dionysius the Areopagite.

While in the East the Church was assuming its permanent form, in the West the condition of the Church was being profoundly influenced by the completely changed political organization of what had been the Roman Empire of the West, but was now parcelled out among new Germanic nationalities. The Church in the various kingdoms, in spite of its adherence to the see of Rome as the centre of Catholic unity, came, to no small extent, under the secular authority, and Christianity in Ireland, in Spain, among the Franks, Anglo-Saxons, and even among the Lombards in Italy assumed a national character, coming largely under the control and subject to the laws and customs of the nation. In this period were laid the foundations of the leading ecclesiastical institutions of the Middle Ages, as the Church, although still under the influence of antiquity, adapted itself and its institutions to the changed condition due to the political situation and took up its duty of training the rude peoples that had come within its fold.

The seventh and eighth centuries saw the completion of the revolution in the ecclesiastical situation. In the East, in the territories in which the national churches of the Monophysites were established, the Moslem rule protected them from the attempts of the orthodox emperors to enforce uniformity. The attempts made to recover their allegiance before they succumbed to Islam had only ended in a serious dispute within the Orthodox Church, the Monothelete controversy, which ended in the Sixth General Council of 681. In Italy the Arian Lombards were gradually won to the Catholic faith, but the Roman see soon found itself embarrassed by the too near secular authority. Accordingly, when the controversy with the East over Iconoclasm broke out, the Roman Church became practically independent of the Eastern imperial authority, and in its conflict with the Lombards came into alliance with the rising Frankish power. With this, the transition to the Middle Ages may be said to have been completed. [pg 540] It was, however, only the last of a series of acts whereby the Church was severing itself from the ancient order and coming into closer alliance with the new order in the life of the West. Henceforth the Church, which found its centre in the Roman see, belongs to the West, and its relations to the East, although no formal schism had occurred, are of continued and increasing estrangement or alienation.
