In this survey we have tried to understand the objections alleged by unbelievers during the first four centuries, successively changing in character, from the calumnies of ignorance in the second century, to the statements of intelligent disbelief in the third and fourth, until they finally subside in the fifth into the murmuring of popular superstition; and have endeavoured to give their natural as well as literary history, by exhibiting them as corollaries from the various views concerning religion enumerated at the commencement of the lecture. The blind prejudices of the uneducated populace, and the attachment, merely political, to heathen creeds, manifested themselves in deeds rather than words; but each of the other lines of thought there indicated gave [pg 070] expression in literature to its opinion concerning Christianity; the flippant impiety of Epicureanism in Lucian, the debased form then prevalent of Platonism in Celsus, the subtle and mystic philosophy of the neo-Platonists in Porphyry, the oriental Theosophy in Hierocles, the romantic attachment to the old pagan literature in Julian.
If these causes be still further classified for comparison with the enumeration of intellectual causes stated in the previous lecture, we find only the adumbration of some of the forms there named. The attack from physical science, so prevalent since the era of modern discovery, is barely discernible in the passing remarks on the Mosaic cosmogony in Celsus and Julian.[246] The attack from criticism is seen in a trifling form in Celsus; in a superior manner in the perception which Porphyry exhibits of the literary characteristics of the Old Testament, and Julian of the New. The chief ground of the attack was derived from metaphysical science, which acted not so much in its modern form of a subjective inquiry into the tests of truth, as in the shape of rival doctrines concerning the highest problems of life and being, which preoccupied the mind against Christianity. If the eclectic attempts to adjust such speculations to Christianity which marked the progress of Gnosticism could have been embraced in our inquiry, the force of this class of causes would have been made still more apparent.
The obvious insufficiency however of this analysis to afford an entire explanation of the prejudices of these early unbelievers points to the close union before noticed[247]of the emotional with the intellectual causes. While asserting the possibility of the independent action of the intellectual element under peculiar circumstances as a cause of doubt, and while thus vindicating the importance [pg 071] of investigating the history of free thought from the intellectual side, we admitted the necessity of taking the probability of the action of the moral element into account when we pass from the abstract study of tendencies to form a judgment on concrete instances. Here accordingly, in the mental history of these early unbelievers, we already encounter cases where philosophy as well as piety requires that a very large share in the final product be referred to the influence of emotional causes. Christianity addresses itself to the compound human nature, to the intellect and heart conjoined. Accordingly the excitement of certain forms of moral sensibility is as much presupposed in religion as the sense of colour in beholding a landscape. The means fail for estimating with historic certainty the particular emotional causes which operated in the instances now under consideration. The moral chasm which separates us from heathens is so great that we can hardly realize their feelings.
If however we cannot pronounce on the positive presence of moral causes which produced their disbelief, we may conjecture negatively the nature of those, the absence of which precluded the possibility of faith. Christianity demands a belief in the supernatural, and a serious spirit in the investigation of religion, both of which were wholly lacking in Lucian. It requires a deep consciousness of guilt and of the personality of God, which were wanting in Celsus. It exacts a more delicate moral taste to appreciate the divine ideal of Christ's character than Hierocles manifested. Porphyry and Julian are more difficult cases for moral analysis. Porphyry is so earnest a character, so spiritual in his tastes,[248] that we wonder why he was not a Christian; and except by the reference of his conduct to general causes, such as philosophical pride, we cannot understand his motives without a more intimate knowledge than is now obtainable of his personal history. The [pg 072] difficulty of understanding Julian's character arises from its very complexity. Who can divine the many motives which must have combined with intellectual causes at successive moments of his life, to change the Christian student, into the apostate, to convert disbelief into hatred, and to degrade the philosopher into the persecutor? History happily offers so few parallels to enable us to form a conjecture on the answer, that we may be content to leave the problem unsolved.
We have now summed up the causes which operated in the first great intellectual struggle in which Christianity was engaged. No means exist for estimating the amount of harm done by the writings of unbelievers. The retributive destruction of some of them and the indignant alarm of the Christian apologists indicate the probability that these works had excited attention. But under a merciful Providence truth has in the end gained rather than lost by this first conflict of reason against Christianity. The church encountered the unbelievers by apologetic treatises, and met the Gnostics by dogmatic decisions. The truths brought out by the action and reaction, and embodied in the literature stimulated by Gnosticism, in the apologies created by unbelief, and in the creeds suggested as a protest against heresy, are the permanent result which the struggle has contributed to the world.
The contest however is not quite obsolete, and has a practical as well as antiquarian interest. Though the analogy to the attacks of ancient unbelievers must be sought in pagan countries in the objections of modern heathens, yet some resemblance to them may be found in the unbelief of Christian lands. Such parallels are frequently hasty generalizations founded on a superficial perception of agreement, without due recognition of the differences which more exact observation would bring to view; for identity of cause as well as result is necessary in order to establish philosophical affinity. In the present cases however the agreement is moral if not intellectual, in spirit if not in form, generally also in condition if not in cause. The flippant wit of Lucian, [pg 073] which attributes religion to imposture and craft, is repeated in the French criticism of the last century. Some of the doubts of Celsus reappear in the English deists. The delicate criticism of Porphyry is reproduced in the modern exegesis. The disposition to explain Christianity as a psychological phenomenon, as merely one form of the religious consciousness, an organic product of human thought, unsuited for men of superior knowledge, who can attain to the philosophical truth which underlies it, is the modern parallel to Julian.
Accordingly the conduct of the early church during this struggle has a living lesson of instruction for the church in Christian lands, as well as in its missionary operations to the heathen. The victory of the early church was not due wholly to intellectual remedies, such as the answers of apologists, but mainly to moral; to the inward perception generated of the adaptation of Christianity to supply the spiritual wants of human nature.[249] As the heathen realized the sense of sin, they felt intuitively the suitability of salvation through Christ; as they witnessed the transforming power of belief in Him, they felt the inward testimony to the truth of Christianity. The external evidence of religion had its office in the early church, though the belief[250] in magic and in oracles probably prevented the full perception of the demonstrative force due to the two forms of external evidence, miracles and prophecy. But the internal evidences,—Christ, Christianity, Christendom, [pg 074] were the most potent proofs offered,—the doctrine of an atoning Messiah filling the heart's deepest longings, and the lives of Christians embodying heavenly virtues.
The modern church may therefore take comfort, and may hope for victory. The weak things of the world confounded the strong, not only because the Holy Spirit granted the dew of his blessing, but because the scheme and message of reconciliation which the church was commissioned to announce, were of divine construction. Each Christian who tries, however humbly, to spread the knowledge of Christ by word or by example is helping forward the Redeemer's kingdom. Let each one in Christ's strength do his duty, and he will leave the world better than he found it; and in the present age, as in the times of old, Gnosticism and heathenism will retire before Christianity; the false will be dissipated, the good be absorbed, by the beams of the Sun of righteousness.
