History of the Decline and Fall of the Roman Empire — Volume 2

by Edward Gibbon

The genius of Plato, informed by his own meditation, or by the traditional knowledge of the priests of Egypt, had ventured to explore the mysterious nature of the Deity. When he had elevated his mind to the sublime contemplation of the first self-existent, necessary cause of the universe, the Athenian sage was incapable of conceiving how the simple unity of his essence could admit the infinite variety of distinct and successive ideas which compose the model of the intellectual world; how a Being purely incorporeal could execute that perfect model, and mould with a plastic hand the rude and independent chaos. The vain hope of extricating himself from these difficulties, which must ever oppress the feeble powers of the human mind, might induce Plato to consider the divine nature under the threefold modification—of the first cause, the reason, or Logos, and the soul or spirit of the universe. His poetical imagination sometimes fixed and animated these metaphysical abstractions; the three archical on original principles were represented in the Platonic system as three Gods, united with each other by a mysterious and ineffable generation; and the Logos was particularly considered under the more accessible character of the Son of an Eternal Father, and the Creator and Governor of the world. Such appear to have been the secret doctrines which were cautiously whispered in the gardens of the academy; and which, according to the more recent disciples of Plato, * could not be perfectly understood, till after an assiduous study of thirty years.

The arms of the Macedonians diffused over Asia and Egypt the language and learning of Greece; and the theological system of Plato was taught, with less reserve, and perhaps with some improvements, in the celebrated school of Alexandria. A numerous colony of Jews had been invited, by the favor of the Ptolemies, to settle in their new capital. While the bulk of the nation practised the legal ceremonies, and pursued the lucrative occupations of commerce, a few Hebrews, of a more liberal spirit, devoted their lives to religious and philosophical contemplation. They cultivated with diligence, and embraced with ardor, the theological system of the Athenian sage. But their national pride would have been mortified by a fair confession of their former poverty: and they boldly marked, as the sacred inheritance of their ancestors, the gold and jewels which they had so lately stolen from their Egyptian masters. One hundred years before the birth of Christ, a philosophical treatise, which manifestly betrays the style and sentiments of the school of Plato, was produced by the Alexandrian Jews, and unanimously received as a genuine and valuable relic of the inspired Wisdom of Solomon. A similar union of the Mosaic faith and the Grecian philosophy, distinguishes the works of Philo, which were composed, for the most part, under the reign of Augustus. The material soul of the universe might offend the piety of the Hebrews: but they applied the character of the Logos to the Jehovah of Moses and the patriarchs; and the Son of God was introduced upon earth under a visible, and even human appearance, to perform those familiar offices which seem incompatible with the nature and attributes of the Universal Cause.

The eloquence of Plato, the name of Solomon, the authority of the school of Alexandria, and the consent of the Jews and Greeks, were insufficient to establish the truth of a mysterious doctrine, which might please, but could not satisfy, a rational mind. A prophet, or apostle, inspired by the Deity, can alone exercise a lawful dominion over the faith of mankind: and the theology of Plato might have been forever confounded with the philosophical visions of the Academy, the Porch, and the Lycæum, if the name and divine attributes of the Logos had not been confirmed by the celestial pen of the last and most sublime of the Evangelists. The Christian Revelation, which was consummated under the reign of Nerva, disclosed to the world the amazing secret, that the Logos, who was with God from the beginning, and was God, who had made all things, and for whom all things had been made, was incarnate in the person of Jesus of Nazareth; who had been born of a virgin, and suffered death on the cross. Besides the general design of fixing on a perpetual basis the divine honors of Christ, the most ancient and respectable of the ecclesiastical writers have ascribed to the evangelic theologian a particular intention to confute two opposite heresies, which disturbed the peace of the primitive church. I. The faith of the Ebionites, perhaps of the Nazarenes, was gross and imperfect. They revered Jesus as the greatest of the prophets, endowed with supernatural virtue and power. They ascribed to his person and to his future reign all the predictions of the Hebrew oracles which relate to the spiritual and everlasting kingdom of the promised Messiah. Some of them might confess that he was born of a virgin; but they obstinately rejected the preceding existence and divine perfections of the Logos, or Son of God, which are so clearly defined in the Gospel of St. John. About fifty years afterwards, the Ebionites, whose errors are mentioned by Justin Martyr with less severity than they seem to deserve, formed a very inconsiderable portion of the Christian name. II. The Gnostics, who were distinguished by the epithet of Docetes, deviated into the contrary extreme; and betrayed the human, while they asserted the divine, nature of Christ. Educated in the school of Plato, accustomed to the sublime idea of the Logos, they readily conceived that the brightest Æon, or Emanation of the Deity, might assume the outward shape and visible appearances of a mortal; but they vainly pretended, that the imperfections of matter are incompatible with the purity of a celestial substance. While the blood of Christ yet smoked on Mount Calvary, the Docetes invented the impious and extravagant hypothesis, that, instead of issuing from the womb of the Virgin, he had descended on the banks of the Jordan in the form of perfect manhood; that he had imposed on the senses of his enemies, and of his disciples; and that the ministers of Pilate had wasted their impotent rage on an airy phantom, who seemed to expire on the cross, and, after three days, to rise from the dead.

The divine sanction, which the Apostle had bestowed on the fundamental principle of the theology of Plato, encouraged the learned proselytes of the second and third centuries to admire and study the writings of the Athenian sage, who had thus marvellously anticipated one of the most surprising discoveries of the Christian revelation. The respectable name of Plato was used by the orthodox, and abused by the heretics, as the common support of truth and error: the authority of his skilful commentators, and the science of dialectics, were employed to justify the remote consequences of his opinions and to supply the discreet silence of the inspired writers. The same subtle and profound questions concerning the nature, the generation, the distinction, and the equality of the three divine persons of the mysterious Triad, or Trinity, were agitated in the philosophical and in the Christian schools of Alexandria. An eager spirit of curiosity urged them to explore the secrets of the abyss; and the pride of the professors, and of their disciples, was satisfied with the sciences of words. But the most sagacious of the Christian theologians, the great Athanasius himself, has candidly confessed, that whenever he forced his understanding to meditate on the divinity of the Logos, his toilsome and unavailing efforts recoiled on themselves; that the more he thought, the less he comprehended; and the more he wrote, the less capable was he of expressing his thoughts. In every step of the inquiry, we are compelled to feel and acknowledge the immeasurable disproportion between the size of the object and the capacity of the human mind. We may strive to abstract the notions of time, of space, and of matter, which so closely adhere to all the perceptions of our experimental knowledge. But as soon as we presume to reason of infinite substance, of spiritual generation; as often as we deduce any positive conclusions from a negative idea, we are involved in darkness, perplexity, and inevitable contradiction. As these difficulties arise from the nature of the subject, they oppress, with the same insuperable weight, the philosophic and the theological disputant; but we may observe two essential and peculiar circumstances, which discriminated the doctrines of the Catholic church from the opinions of the Platonic school.

I. A chosen society of philosophers, men of a liberal education and curious disposition, might silently meditate, and temperately discuss in the gardens of Athens or the library of Alexandria, the abstruse questions of metaphysical science. The lofty speculations, which neither convinced the understanding, nor agitated the passions, of the Platonists themselves, were carelessly overlooked by the idle, the busy, and even the studious part of mankind. But after the Logos had been revealed as the sacred object of the faith, the hope, and the religious worship of the Christians, the mysterious system was embraced by a numerous and increasing multitude in every province of the Roman world. Those persons who, from their age, or sex, or occupations, were the least qualified to judge, who were the least exercised in the habits of abstract reasoning, aspired to contemplate the economy of the Divine Nature: and it is the boast of Tertullian, that a Christian mechanic could readily answer such questions as had perplexed the wisest of the Grecian sages. Where the subject lies so far beyond our reach, the difference between the highest and the lowest of human understandings may indeed be calculated as infinitely small; yet the degree of weakness may perhaps be measured by the degree of obstinacy and dogmatic confidence. These speculations, instead of being treated as the amusement of a vacant hour, became the most serious business of the present, and the most useful preparation for a future, life. A theology, which it was incumbent to believe, which it was impious to doubt, and which it might be dangerous, and even fatal, to mistake, became the familiar topic of private meditation and popular discourse. The cold indifference of philosophy was inflamed by the fervent spirit of devotion; and even the metaphors of common language suggested the fallacious prejudices of sense and experience. The Christians, who abhorred the gross and impure generation of the Greek mythology, were tempted to argue from the familiar analogy of the filial and paternal relations. The character of Son seemed to imply a perpetual subordination to the voluntary author of his existence; but as the act of generation, in the most spiritual and abstracted sense, must be supposed to transmit the properties of a common nature, they durst not presume to circumscribe the powers or the duration of the Son of an eternal and omnipotent Father. Fourscore years after the death of Christ, the Christians of Bithynia, declared before the tribunal of Pliny, that they invoked him as a god: and his divine honors have been perpetuated in every age and country, by the various sects who assume the name of his disciples. Their tender reverence for the memory of Christ, and their horror for the profane worship of any created being, would have engaged them to assert the equal and absolute divinity of the Logos, if their rapid ascent towards the throne of heaven had not been imperceptibly checked by the apprehension of violating the unity and sole supremacy of the great Father of Christ and of the Universe. The suspense and fluctuation produced in the minds of the Christians by these opposite tendencies, may be observed in the writings of the theologians who flourished after the end of the apostolic age, and before the origin of the Arian controversy. Their suffrage is claimed, with equal confidence, by the orthodox and by the heretical parties; and the most inquisitive critics have fairly allowed, that if they had the good fortune of possessing the Catholic verity, they have delivered their conceptions in loose, inaccurate, and sometimes contradictory language.

II. The devotion of individuals was the first circumstance which distinguished the Christians from the Platonists: the second was the authority of the church. The disciples of philosophy asserted the rights of intellectual freedom, and their respect for the sentiments of their teachers was a liberal and voluntary tribute, which they offered to superior reason. But the Christians formed a numerous and disciplined society; and the jurisdiction of their laws and magistrates was strictly exercised over the minds of the faithful. The loose wanderings of the imagination were gradually confined by creeds and confessions; the freedom of private judgment submitted to the public wisdom of synods; the authority of a theologian was determined by his ecclesiastical rank; and the episcopal successors of the apostles inflicted the censures of the church on those who deviated from the orthodox belief. But in an age of religious controversy, every act of oppression adds new force to the elastic vigor of the mind; and the zeal or obstinacy of a spiritual rebel was sometimes stimulated by secret motives of ambition or avarice. A metaphysical argument became the cause or pretence of political contests; the subtleties of the Platonic school were used as the badges of popular factions, and the distance which separated their respective tenets were enlarged or magnified by the acrimony of dispute. As long as the dark heresies of Praxeas and Sabellius labored to confound the Father with the Son, the orthodox party might be excused if they adhered more strictly and more earnestly to the distinction, than to the equality, of the divine persons. But as soon as the heat of controversy had subsided, and the progress of the Sabellians was no longer an object of terror to the churches of Rome, of Africa, or of Egypt, the tide of theological opinion began to flow with a gentle but steady motion towards the contrary extreme; and the most orthodox doctors allowed themselves the use of the terms and definitions which had been censured in the mouth of the sectaries. After the edict of toleration had restored peace and leisure to the Christians, the Trinitarian controversy was revived in the ancient seat of Platonism, the learned, the opulent, the tumultuous city of Alexandria; and the flame of religious discord was rapidly communicated from the schools to the clergy, the people, the province, and the East. The abstruse question of the eternity of the Logos was agitated in ecclesiastic conferences and popular sermons; and the heterodox opinions of Arius were soon made public by his own zeal, and by that of his adversaries. His most implacable adversaries have acknowledged the learning and blameless life of that eminent presbyter, who, in a former election, had declared, and perhaps generously declined, his pretensions to the episcopal throne. His competitor Alexander assumed the office of his judge. The important cause was argued before him; and if at first he seemed to hesitate, he at length pronounced his final sentence, as an absolute rule of faith. The undaunted presbyter, who presumed to resist the authority of his angry bishop, was separated from the community of the church. But the pride of Arius was supported by the applause of a numerous party. He reckoned among his immediate followers two bishops of Egypt, seven presbyters, twelve deacons, and (what may appear almost incredible) seven hundred virgins. A large majority of the bishops of Asia appeared to support or favor his cause; and their measures were conducted by Eusebius of Cæsarea, the most learned of the Christian prelates; and by Eusebius of Nicomedia, who had acquired the reputation of a statesman without forfeiting that of a saint. Synods in Palestine and Bithynia were opposed to the synods of Egypt. The attention of the prince and people was attracted by this theological dispute; and the decision, at the end of six years, was referred to the supreme authority of the general council of Nice.
