One can scarcely pass by a leap of thought from the age of Paul to the age of Dante without an instant's glance at the intervening tract. There are the early Christian communities, bound together by tender ties of brotherhood; storms of persecution fanning high the flame of courage and faith; a new purity and sweetness of domestic life spreading itself like the coming of the dawn. There are wild vagaries of the mind, taking shape in fantastic heresies. There is the degeneracy of a faith held in pureness and peril into a popular and fashionable religion. There are enthroned monsters like Nero and Commodus; "Christian" emperors, like Constantine, ambitious, crafty, and blood-guilty; and noble "heathen" emperors like Trajan and Aurelius. There is the peace of the Empire in its best days, with some wide diffusion of prosperity and content. There are incursions of barbarians—the strange, little-known life of nomadic tribes—with pristine virtues of valor and chastity, half-pictured, half-imagined, by Tacitus. There is conquest, rapine, subjugation, suffering. There are ages in which violence is master, and in the disordered struggle of the violent among themselves the weak are trampled under foot. There are scenes of humble happiness and content, the toiler in the fields, the family about the hearth-stone, which scarcely are seen by the chronicler busy with kings and popes. There are superstitions and mummeries; wild fears of spectres and devils; sentimental piety handed with cruelty and debauchery. There are inward struggles, sorrows, achievements; rapturous glimpses, tender consolations; the ministry of faithful priests; the comforting of women and the purifying of men by the thought of the Virgin Mother and the saints. There are civilizers in state and church,—Alfred, Charlemagne, Hildebrand. There is the emergence of a social and ecclesiastical order; the ranking of kings, barons, and vassals; of priests, bishops, and popes; the establishment of laws and charters; the growth of liturgies and cathedrals.
The contrast is great between the simplicity of a high moral ideal, like that of Jesus or Paul, which claims, and with such show of reason and right, the whole allegiance of man, and the vast complexity of good and evil in which the ideal works only as one obscure and partial element. How simple, how clear, how sweetly inviting sounds the call,—how strange and discordant the response!
That inconsistency was explained by the church fathers, like Augustine, as due to the inherent badness of human nature. That universal badness flowed from one sin of the common ancestor. That sin was induced by the machinations of Satan, arch-enemy of God, and practically dividing the rule of the universe with him. A logical and symmetrical explanation in its day, but it no longer explains.
Neither does it explain, but it may profit, if the wondering inquirer turns his thoughts for a moment on his personal history. He has had his hours of clear vision and high resolve,—why have they borne such poor fruit in his actual life? His own riddle is one with the riddle of history.
Again we may say, with no pretense of probing the mystery in its depths, but as gaining a touch of side-light, it is plain that what we look at as the strictly moral forces of mankind—the clear thinking, the definite purpose, the pure aspiration—must be reckoned with as only a part of the volume of force that carries along the individual and the race. Other elements of that force are the physical needs; the push and play of passions ingrained in human nature; the inherited bias; the strength of habits formed before childhood had begun to reflect,—the thousand forces which blend with reason and choice to make up our destiny. Man's noblest aim is to make reason and purpose the rulers in his little republic, but at the best those rulers must deal with a set of very vigorous and often mutinous subjects.
Let us not at least wonder, though for the moment we sigh, that neither did the kingdom of God at once establish itself on earth, as Jesus hoped, nor did the Spirit guide mankind by a brief and sure path into full felicity and holiness, as Paul hoped.
The disappointment is a blank contradiction only for those who assume a superhuman revelation in Scripture or in church, and then have to reconcile this infallibility with that most fallible groping by which alone mankind gets along. Unembarrassed at least by that difficulty, let us note one natural cause of the imperfect progress of Christianity, namely, the substitution of fancy for clear and sound knowledge of nature and man, which was inwrought from the beginning in its creed.
We may recall the piercing question of Socrates, "Can virtue be taught?" Can the best life be so clearly shown and so skillfully inculcated, that it may be transmitted from man to man and from generation to generation as surely and safely as the knowledge of a mechanical art or a physical science? Socrates owned that he knew of no such way to teach virtue,—that while Pericles could teach his son to be a good horseman, he could not so guide him but that he became a bad man,—and Socrates himself found no sure way to guide men into the heroic path he walked himself.
Now Christianity offered a sort of knowledge as the proper training to produce virtue. Its knowledge included certain genuine and precious elements, such as the essential blessedness of purity and love; the trust and peace which flow from duty done; the hope which springs from the grave of a holy man;—ideas not new in substance, but wonderfully vivified and vitalized. But along with this genuine knowledge, Christianity blended in ever-growing volume a pseudo-knowledge. It had a professed explanation of the nature of Deity, the nature of humanity, and their mutual relation, which was so unreal that when applied to the conduct of human life its fruit was often as ashes and the east wind.
To sum up the method by which Christianity wrought: its vital ideas of character were infolded in a triple crust of Authority, Ceremony, Dogma. Its ideas could scarcely have been propagated except under some such incrustation. Pure gold must be mixed with alloy before it can be worked. The new society would have quickly dissolved into chaos if it had not had established laws and usages and discipline and rulers. The craving of the average man for definite symbols fastened eagerly on the cleansing water of baptism and the bread and wine of the love-feast. The thoughtful mind must needs seek to assign to the Master his true place and relation as between God and man. Here were the germs of hierarchy, ceremonial, and dogma. Internal order, self-protection against persecuting emperors and then against barbarian invaders, led to a gradual strengthening and perfecting of the organization. The craving for intellectual consistency and symmetry urged on the elaboration of the creed.
