§ 1. Introduction and General View.

From the Christianity of the Apostles and Martyrs we proceed to the Christianity of the Patriarchs and Emperors.

The third period of the history of the Church, which forms the subject of this volume, extends from the emperor Constantine to the pope Gregory I.; from the beginning of the fourth century to the close of the sixth. During this period Christianity still moves, as in the first three centuries, upon the geographical scene of the Graeco-Roman empire and the ancient classical culture, the countries around the Mediterranean Sea. But its field and its operation are materially enlarged, and even touch the barbarians on the limit of the empire. Above all, its relation to the temporal power, and its social and political position and import, undergo an entire and permanent change. We have here to do with the church of the Graeco-Roman empire, and with the beginning of Christianity among the Germanic barbarians. Let us glance first at the general character and leading events of this important period.

The reign of Constantine the Great marks the transition of the Christian religion from under persecution by the secular government to union with the same; the beginning of the state-church system. The Graeco-Roman heathenism, the most cultivated and powerful form of idolatry, which history knows, surrenders, after three hundred years’ struggle, to Christianity, and dies of incurable consumption, with the confession: Galilean, thou hast conquered! The ruler of the civilized world lays his crown at the feet of the crucified Jesus of Nazareth. The successor of Nero, Domitian, and Diocletian appears in the imperial purple at the council of Nice as protector of the church, and takes his golden throne at the nod of bishops, who still bear the scars of persecution. The despised sect, which, like its Founder in the days of His humiliation, had not where to lay its head, is raised to sovereign authority in the state, enters into the prerogatives of the pagan priesthood, grows rich and powerful, builds countless churches out of the stones of idol temples to the honor of Christ and his martyrs, employs the wisdom of Greece and Rome to vindicate the foolishness of the cross, exerts a molding power upon civil legislation, rules the national life, and leads off the history of the world. But at the same time the church, embracing the mass of the population of the empire, from the Caesar to the meanest slave, and living amidst all its institutions, received into her bosom vast deposits of foreign material from the world and from heathenism, exposing herself to new dangers and imposing upon herself new and heavy labors.

The union of church and state extends its influence, now healthful, now baneful, into every department of our history.

The Christian life of the Nicene and post-Nicene age reveals a mass of worldliness within the church; an entire abatement of chiliasm with its longing after the return of Christ and his glorious reign, and in its stead an easy repose in the present order of things; with a sublime enthusiasm, on the other hand, for the renunciation of self and the world, particularly in the hermitage and the cloister, and with some of the noblest heroes of Christian holiness.

Monasticism, in pursuance of the ascetic tendencies of the previous period, and in opposition to the prevailing secularization of Christianity, sought to save the virgin purity of the church and the glory of martyrdom by retreat from the world into the wilderness; and it carried the ascetic principle to the summit of moral heroism, though not rarely to the borders of fanaticism and brutish stupefaction. It spread with incredible rapidity and irresistible fascination from Egypt over the whole church, east and west, and received the sanction of the greatest church teachers, of an Athanasius, a Basil, a Chrysostom, an Augustine, a Jerome, as the surest and shortest way to heaven.

It soon became a powerful rival of the priesthood, and formed a third order, between the priesthood and the laity. The more extraordinary and eccentric the religion of the anchorets and monks, the more they were venerated among the people. The whole conception of the Christian life from the fourth to the sixteenth century is pervaded with the ascetic and monastic spirit, and pays the highest admiration to the voluntary celibacy, poverty, absolute obedience, and excessive self-punishments of the pillar-saints and the martyrs of the desert; while in the same degree the modest virtues of every-day household and social life are looked upon as an inferior degree of morality.

In this point the old Catholic ethical ideas essentially differ from those of evangelical Protestantism and modern civilization. But, to understand and appreciate them, we must consider them in connection with the corrupt social condition of the rapidly decaying empire of Rome. The Christian spirit in that age, in just its most earnest and vigorous forms, felt compelled to assume in some measure an anti-social, seclusive character, and to prepare itself in the school of privation and solitude for the work of transforming the world and founding a new Christian order of society upon the ruins of the ancient heathenism.

In the development of doctrine the Nicene and post-Nicene age is second in productiveness and importance only to those of the apostles and of the reformation. It is the classical period for the objective fundamental dogmas, which constitute the ecumenical or old Catholic confession of faith. The Greek church produced the symbolical definition of the orthodox view of the holy Trinity and the person of Christ, while the Latin church made considerable advance with the anthropological and soteriological doctrines of sin and grace. The fourth and fifth centuries produced the greatest church fathers, Athanasius and Chrysostom in the East, Jerome and Augustine in the West. All learning and science now came into the service of the church, and all classes of society, from the emperor to the artisan, took the liveliest, even a passionate interest, in the theological controversies. Now, too, for the first time, could ecumenical councils be held, in which the church of the whole Roman empire was represented, and fixed its articles of faith in an authoritative way.

Now also, however, the lines of orthodoxy were more and more strictly drawn; freedom of inquiry was restricted; and all as departure from the state-church system was met not only, as formerly, with spiritual weapons, but also with civil punishments. So early as the fourth century the dominant party, the orthodox as well as the heterodox, with help of the imperial authority practised deposition, confiscation, and banishment upon its opponents. It was but one step thence to the penalties of torture and death, which were ordained in the middle age, and even so lately as the middle of the seventeenth century, by state-church authority, both Protestant and Roman Catholic, and continue in many countries to this day, against religious dissenters of every kind as enemies to the prevailing order of things. Absolute freedom of religion and of worship is in fact logically impossible on the state-church system. It requires the separation of the spiritual and temporal powers. Yet, from the very beginning of political persecution, loud voices rise against it and in behalf of ecclesiastico-religious toleration; though the plea always comes from the oppressed party, which, as soon as it gains the power, is generally found, in lamentable inconsistency, imitating the violence of its former oppressors. The protest springs rather from the sense of personal injury, than from horror of the principle of persecution, or from any clear apprehension of the nature of the gospel and its significant words: “Put up thy sword into the sheath;” “My kingdom is not of this world.”

The organization of the church adapts itself to the political and geographical divisions of the empire. The powers of the hierarchy are enlarged, the bishops become leading officers of the state and acquire a controlling influence in civil and political affairs, though more or less at the expense of their spiritual dignity and independence, especially at the Byzantine court. The episcopal system passes on into the metropolitan and patriarchal. In the fifth century the patriarchs of Rome, Constantinople, Antioch, Alexandria, and Jerusalem stand at the head of Christendom. Among these Rome and Constantinople are the most powerful rivals, and the Roman patriarch already puts forth a claim to universal spiritual supremacy, which subsequently culminates in the mediaeval papacy, though limited to the West and resisted by the constant protest of the Greek church and of all non-Catholic sects. In addition to provincial synods we have now also general synods, but called by the emperors and more or less affected, though not controlled, by political influence.

From the time of Constantine church discipline declines; the whole Roman world having become nominally Christian, and the host of hypocritical professors multiplying beyond all control. Yet the firmness of Ambrose with the emperor Theodosius shows, that noble instances of discipline are not altogether wanting.

Worship appears greatly enriched and adorned; for art now comes into the service of the church. A Christian architecture, a Christian sculpture, a Christian painting, music, and poetry arise, favoring at once devotion and solemnity, and all sorts of superstition and empty display. The introduction of religious images succeeds only after long and violent opposition. The element of priesthood and of mystery is developed, but in connection with a superstitious reliance upon a certain magical operation of outward rites. Church festivals are multiplied and celebrated with great pomp; and not exclusively in honor of Christ, but in connection with an extravagant veneration of martyrs and saints, which borders on idolatry, and often reminds us of the heathen hero-worship not yet uprooted from the general mind. The multiplication and accumulation of religious ceremonies impressed the senses and the imagination, but prejudiced simplicity, spirituality, and fervor in the worship of God. Hence also the beginnings of reaction against ceremonialism and formalism.

Notwithstanding the complete and sudden change of the social and political circumstances of the church, which meets us on the threshold of this period, we have still before us the natural, necessary continuation of the pre-Constantine church in its light and shade, and the gradual transition of the old Graeco-Roman Catholicism into the Germano-Roman Catholicism of the middle age.

Our attention will now for the first time be turned in earnest, not only to Christianity in the Roman empire, but also to Christianity among the Germanic barbarians, who from East and North threaten the empire and the entire civilization of classic antiquity. The church prolonged, indeed, the existence of the Roman empire, gave it a new splendor and elevation, new strength and unity, as well as comfort in misfortune; but could not prevent its final dissolution, first in the West (a.d. 476), afterwards (1453) in the East. But she herself survived the storms of the great migration, brought the pagan invaders under the influence of Christianity, taught the barbarians the arts of peace, planted a higher civilization upon the ruins of the ancient world, and thus gave new proof of the indestructible, all-subduing energy of her life.

In a minute history of the fourth, fifth, and sixth centuries we should mark the following subdivisions:

1. The Constantinian and Athanasian, or the Nicene and Trinitarian age, from 311 to the second general council in 381, distinguished by the conversion of Constantine, the alliance of the empire with the church, and the great Arian and semi-Arian controversy concerning the Divinity of Christ and the Holy Spirit.

2. The post-Nicene, or Christological and Augustinian age, extending to the fourth general council in 451, and including the Nestorian and Eutychian disputes on the person of Christ, and the Pelagian controversy on sin and grace.

3. The age of Leo the Great (440–461), or the rise of the papal supremacy in the West, amidst the barbarian devastations which made an end to the western Roman empire in 476.

4. The Justinian age (527–565), which exhibits the Byzantine state-church despotism at the height of its power, and at the beginning of its decline.

5. The Gregorian age (590–604) forms the transition from the ancient Graeco-Roman to the mediaeval Romano-Germanic Christianity, and will be more properly included in the church history of the middle ages.
