26. The Emperor-Papacy and the Hierarchy. (Chapter 3. Alliance of Church and State and its Influence on Public Morals?...) (History of the Christian Church) (Schaff, Philip)

And this, in point of fact, took place first under Constantine, and developed under his successors, particularly under Justinian, into the system of the Byzantine imperial papacy, or of the supremacy of the state over the church.

Constantine once said to the bishops at a banquet, that he also, as a Christian emperor, was a divinely appointed bishop, a bishop over the external affairs of the church, while the internal affairs belonged to the bishops proper. In this pregnant word he expressed the new posture of the civil sovereign toward the church in a characteristic though indefinite and equivocal way. He made there a distinction between two divinely authorized episcopates; one secular or imperial, corresponding with the old office of Pontifex Maximus, and extending over the whole Roman empire, therefore ecumenical or universal; the other spiritual or sacerdotal, divided among the different diocesan bishops, and appearing properly in its unity and totality only in a general council.

Accordingly, though not yet even baptized, he acted as the patron and universal temporal bishop of the church; summoned the first ecumenical council for the settlement of the controversy respecting the divinity of Christ; instituted and deposed bishops; and occasionally even delivered sermons to the people; but on the other hand, with genuine tact (though this was in his earlier period, a.d. 314), kept aloof from the Donatist controversy, and referred to the episcopal tribunal as the highest and last resort in purely spiritual matters. In the exercise of his imperial right of supervision he did not follow any clear insight and definite theory so much as an instinctive impulse of control, a sense of politico-religious duty, and the requirements of the time. His word only raised, did not solve, the question of the relation between the imperial and the sacerdotal episcopacy and the extent of their respective jurisdictions in a Christian state.

This question became thenceforth the problem and the strife of history both sacred and secular, ran through the whole mediaeval conflict between emperor and pope, between imperial and hierarchical episcopacy, and recurs in modified form in every Protestant established church.

In general, from this time forth the prevailing view was, that God has divided all power between the priesthood and the kingdom (sacerdotium et imperium), giving internal or spiritual affairs, especially doctrine and worship, to the former, and external or temporal affairs, such as government and discipline, to the latter. But internal and external here vitally interpenetrate and depend on each other, as soul and body, and frequent reciprocal encroachments and collisions are inevitable upon state-church ground. This becomes manifest in the period before us in many ways, especially in the East, where the Byzantine despotism had freer play, than in the distant West.

The emperors after Constantine (as the popes after them) summoned the general councils, bore the necessary expenses, presided in the councils through commissions, gave to the decisions in doctrine and discipline the force of law for the whole Roman empire, and maintained them by their authority. The emperors nominated or confirmed the most influential metropolitans and patriarchs. They took part in all theological disputes, and thereby inflamed the passion of parties. They protected orthodoxy and punished heresy with the arm of power. Often, however, they took the heretical side, and banished orthodox bishops from their sees. Thus Arianism, Nestorianism, Eutychianism, and Monophysitism successively found favor and protection at court. Even empresses meddled in the internal and external concerns of the church. Justina endeavored with all her might to introduce Arianism in Milan, but met a successful opponent in bishop Ambrose. Eudoxia procured the deposition and banishment of the noble Chrysostom. Theodora, raised from the stage to the throne, ruled the emperor Justinian, and sought by every kind of intrigue to promote the victory of the Monophysite heresy. It is true, the doctrinal decisions proceeded properly from the councils, and could not have maintained themselves long without that sanction. But Basiliscus, Zeno, Justinian I., Heraclius, Constans II., and other emperors issued many purely ecclesiastical edicts and rescripts without consulting the councils, or through the councils by their own influence upon them. Justinian opens his celebrated codex with the imperial creed on the trinity and the imperial anathema against Nestorius, Eutyches, Apollinaris, on the basis certainly of the apostolic church and of the four ecumenical councils, but in the consciousness of absolute legislative and executive authority even over the faith and conscience of all his subjects.

The voice of the catholic church in this period conceded to the Christian emperors in general, with the duty of protecting and supporting the church, the right of supervision over its external affairs, but claimed for the clergy, particularly for the bishops, the right to govern her within, to fix her doctrine, to direct her worship. The new state of things was regarded as a restoration of the Mosaic and Davidic theocracy on Christian soil, and judged accordingly. But in respect to the extent and application of the emperor's power in the church, opinion was generally determined, consciously or unconsciously, by some special religious interest. Hence we find that catholics and heretics, Athanasians and Arians, justified or condemned the interference of the emperor in the development of doctrine, the appointment and deposition of bishops, and the patronage and persecution of parties, according as they themselves were affected by them. The same Donatists who first appealed to the imperial protection, when the decision went against them denounced all intermeddling of the state with the church. There were bishops who justified even the most arbitrary excesses of the Byzantine despotism in religion by reference to Melchizedek and the pious kings of Israel, and yielded them selves willing tools of the court. But there were never wanting also fearless defenders of the rights of the church against the civil power. Maximus the Confessor declared before his judges in Constantinople, that Melchizedek was a type of Christ alone, not of the emperor.

In general the hierarchy formed a powerful and wholesome check on the imperial papacy, and preserved the freedom and independence of the church toward the temporal power. That age had only the alternative of imperial or episcopal despotism; and of these the latter was the less hurtful and the more profitable, because it represented the higher intellectual and moral interests. Without the hierarchy, the church in the Roman empire and among the barbarians would have been the football of civil and military despots. It was, therefore, of the utmost importance, that the church, at the time of her marriage with the state, had already grown so large and strong as to withstand all material alteration by imperial caprice, and all effort to degrade her into a tool. The Apostolic Constitutions place the bishops even above all kings and magistrates. Chrysostom says that the first ministers of the state enjoyed no such honor as the ministers of the church. And in general the ministers of the church deserved their honor. Though there were prelates enough who abused their power to sordid ends, still there were men like Athanasius, Basil, Ambrose, Chrysostom, Augustine, Leo, the purest and most venerable characters, which meet us in the fourth and fifth centuries, far surpassing the contemporary emperors. It was the universal opinion that the doctrines and institutions of the church, resting on divine revelation, are above all human power and will. The people looked, in blind faith and superstition, to the clergy as their guides in all matters of conscience, and even the emperors had to pay the bishops, as the fathers of the churches, the greatest reverence, kiss their hands, beg their blessing, and submit to their admonition and discipline. In most cases the emperors were mere tools of parties in the church. Arbitrary laws which were imposed upon the church from without rarely survived their makers, and were condemned by history. For there is a divine authority above all thrones, and kings, and bishops, and a power of truth above all the machinations of falsehood and intrigue.

The Western church, as a whole, preserved her independence far more than the Eastern; partly through the great firmness of the Roman character, partly through the favor of political circumstances, and of remoteness from the influence and the intrigues of the Byzantine court. Here the hierarchical principle developed itself from the time of Leo the Great even to the absolute papacy, which, however, after it fulfilled its mission for the world among the barbarian nations of the middle ages, degenerated into an insufferable tyranny over conscience, and thus exposed itself to destruction. In the Catholic system the freedom and independence of the church involve the supremacy of an exclusive priesthood and papacy; in the Protestant, they can be realized only on the broader basis of the universal priesthood, in the self-government of the Christian people; though this is, as yet, in all Protestant established churches more or less restricted by the power of the state.
