Such was the mild and equal constitution by which the Christians were governed more than a hundred years after the death of the apostles. Every society formed within itself a separate and independent republic; and although the most distant of these little states maintained a mutual as well as friendly intercourse of letters and deputations, the Christian world was not yet connected by any supreme authority or legislative assembly. As the numbers of the faithful were gradually multiplied, they discovered the advantages that might result from a closer union of their interest and designs. Towards the end of the second century, the churches of Greece and Asia adopted the useful institutions of provincial synods, * and they may justly be supposed to have borrowed the model of a representative council from the celebrated examples of their own country, the Amphictyons, the Achaean league, or the assemblies of the Ionian cities. It was soon established as a custom and as a law, that the bishops of the independent churches should meet in the capital of the province at the stated periods of spring and autumn. Their deliberations were assisted by the advice of a few distinguished presbyters, and moderated by the presence of a listening multitude. 115 Their decrees, which were styled Canons, regulated every important controversy of faith and discipline; and it was natural to believe that a liberal effusion of the Holy Spirit would be poured on the united assembly of the delegates of the Christian people. The institution of synods was so well suited to private ambition, and to public interest, that in the space of a few years it was received throughout the whole empire. A regular correspondence was established between the provincial councils, which mutually communicated and approved their respective proceedings; and the catholic church soon assumed the form, and acquired the strength, of a great foederative republic. 116
As the legislative authority of the particular churches was insensibly superseded by the use of councils, the bishops obtained by their alliance a much larger share of executive and arbitrary power; and as soon as they were connected by a sense of their common interest, they were enabled to attack with united vigor, the original rights of their clergy and people. The prelates of the third century imperceptibly changed the language of exhortation into that of command, scattered the seeds of future usurpations, and supplied, by scripture allegories and declamatory rhetoric, their deficiency of force and of reason. They exalted the unity and power of the church, as it was represented in the Episcopal Office, of which every bishop enjoyed an equal and undivided portion. 117 Princes and magistrates, it was often repeated, might boast an earthly claim to a transitory dominion; it was the episcopal authority alone which was derived from the Deity, and extended itself over this and over another world. The bishops were the vicegerents of Christ, the successors of the apostles, and the mystic substitutes of the high priest of the Mosaic law. Their exclusive privilege of conferring the sacerdotal character, invaded the freedom both of clerical and of popular elections; and if, in the administration of the church, they still consulted the judgment of the presbyters, or the inclination of the people, they most carefully inculcated the merit of such a voluntary condescension. The bishops acknowledged the supreme authority which resided in the assembly of their brethren; but in the government of his peculiar diocese, each of them exacted from his flock the same implicit obedience as if that favorite metaphor had been literally just, and as if the shepherd had been of a more exalted nature than that of his sheep. 118 This obedience, however, was not imposed without some efforts on one side, and some resistance on the other. The democratical part of the constitution was, in many places, very warmly supported by the zealous or interested opposition of the inferior clergy. But their patriotism received the ignominious epithets of faction and schism; and the episcopal cause was indebted for its rapid progress to the labors of many active prelates, who, like Cyprian of Carthage, could reconcile the arts of the most ambitious statesman with the Christian virtues which seem adapted to the character of a saint and martyr. 119
The same causes which at first had destroyed the equality of the presbyters introduced among the bishops a preeminence of rank, and from thence a superiority of jurisdiction. As often as in the spring and autumn they met in provincial synod, the difference of personal merit and reputation was very sensibly felt among the members of the assembly, and the multitude was governed by the wisdom and eloquence of the few. But the order of public proceedings required a more regular and less invidious distinction; the office of perpetual presidents in the councils of each province was conferred on the bishops of the principal city; and these aspiring prelates, who soon acquired the lofty titles of Metropolitans and Primates, secretly prepared themselves to usurp over their episcopal brethren the same authority which the bishops had so lately assumed above the college of presbyters. 120 Nor was it long before an emulation of preeminence and power prevailed among the Metropolitans themselves, each of them affecting to display, in the most pompous terms, the temporal honors and advantages of the city over which he presided; the numbers and opulence of the Christians who were subject to their pastoral care; the saints and martyrs who had arisen among them; and the purity with which they preserved the tradition of the faith, as it had been transmitted through a series of orthodox bishops from the apostle or the apostolic disciple, to whom the foundation of their church was ascribed. 121 From every cause, either of a civil or of an ecclesiastical nature, it was easy to foresee that Rome must enjoy the respect, and would soon claim the obedience of the provinces. The society of the faithful bore a just proportion to the capital of the empire; and the Roman church was the greatest, the most numerous, and, in regard to the West, the most ancient of all the Christian establishments, many of which had received their religion from the pious labors of her missionaries. Instead of one apostolic founder, the utmost boast of Antioch, of Ephesus, or of Corinth, the banks of the Tyber were supposed to have been honored with the preaching and martyrdom of the two most eminent among the apostles; 122 and the bishops of Rome very prudently claimed the inheritance of whatsoever prerogatives were attributed either to the person or to the office of St. Peter. 123 The bishops of Italy and of the provinces were disposed to allow them a primacy of order and association (such was their very accurate expression) in the Christian aristocracy. 124 But the power of a monarch was rejected with abhorrence, and the aspiring genius of Rome experienced from the nations of Asia and Africa a more vigorous resistance to her spiritual, than she had formerly done to her temporal, dominion. The patriotic Cyprian, who ruled with the most absolute sway the church of Carthage and the provincial synods, opposed with resolution and success the ambition of the Roman pontiff, artfully connected his own cause with that of the eastern bishops, and, like Hannibal, sought out new allies in the heart of Asia. 125 If this Punic war was carried on without any effusion of blood, it was owing much less to the moderation than to the weakness of the contending prelates. Invectives and excommunications were their only weapons; and these, during the progress of the whole controversy, they hurled against each other with equal fury and devotion. The hard necessity of censuring either a pope, or a saint and martyr, distresses the modern Catholics whenever they are obliged to relate the particulars of a dispute in which the champions of religion indulged such passions as seem much more adapted to the senate or to the camp. 126
The progress of the ecclesiastical authority gave birth to the memorable distinction of the laity and of the clergy, which had been unknown to the Greeks and Romans. 127
