...The final fate of Christianity is dependent upon our need of it. This religion has for eighteen centuries been a blessing to suffering humanity; it was providential, divine, holy. All that it has benefited civilisation, by taming the strong and strengthening the weak, by uniting the nations through like emotions and a like language, by all that its panegyrists extol—all these are insignificant in comparison with that great consolation which in itself is bestowed upon mankind. Eternal praise is due to that symbol of a suffering God, the Saviour with the crown of thorns, the Christ crucified, whose blood was a soothing balsam dripping into humanity's wounds. The poet, in particular, will reverently recognise the solemn grandeur of that symbol. The whole system of allegory, as expressed in the life and art of the middle ages, will in all times excite the admiration of poets. What colossal consistency in the Christian art!—that is, in architecture! How harmoniously those Gothic cathedrals are adapted to the religious services of the Church, and how the fundamental idea of the Church itself is revealed in them! Everything towers upward; everything transubstantiates itself; the stone blossoms into branches and foliage and becomes a tree; the fruits of the vine and of the wheat-stalk become blood and flesh; man becomes God, and God becomes a pure, abstract spirit. The Christian life during the middle ages is for the poet a rich, inexhaustible store-house of precious materials. Only through Christianity could, in this world, such varied phases arise—contrasts so striking, sorrows so diverse, beauties so strange, that one is inclined to believe that they never did exist in reality, and that all was but a colossal fever-dream, a delirious fantasy of an insane God. Nature herself appeared in those times fantastically disguised; but notwithstanding that man, occupied with abstract metaphysical speculations, turned peevishly away from her, yet at times she awoke him with a voice so solemnly sweet, so deliciously terrible, so enchanting, that he involuntarily listened and smiled, then shrank back with terror, and sickened even unto death. The story of the nightingale of Basle here comes to my mind, and, as it is probably unknown to you, I will relate it.

In May 1433, at the time of the Ecumenical Council, a party of ecclesiastics, prelates, learned scholars, and monks of every shades took a walk in a grove near Basle, wrangling over theological disputations, drawing hair-splitting distinctions, or arguing concerning annates, expectatives, and reservations, debating whether Thomas of Aquinas was a greater philosopher than Bonaventura, and what not! But suddenly, in the midst of their abstract and dogmatical discussions, they paused, transfixed, before a blooming linden-tree, on which sat a nightingale, trilling and trolling the sweetest and tenderest strains. The learned men were ravished with delight. The glowing melodies of spring penetrated to their scholastic, musty, bookworm hearts, their souls awoke from the mouldy, wintry sleep, they looked at one another in astonished ecstasy. But finally one of them made the sagacious remark that such things could not come of good, that the nightingale might be a devil, and that this devil might be seeking through its sweet music to decoy them from their pious conversations and to lure them to voluptuousness and similar pleasant sins; and then he began to exorcise, probably with the usual formula—"Adjuro te per cum, qui venturus est, judicare vivos et mortuos," etc. It is said that at this conjuration the bird replied, "Yes, I am an evil spirit!" and flew away, laughing. But those who heard its song sickened that very night, and soon after died.

This legend needs no commentary. It bears distinctly the horrible impress of a time when all that was sweet and lovely was denounced as diabolical. Even the nightingale was slandered, and it was customary to make the sign of the cross when she sang. The true Christian, like an abstract spectre, walked timorously, with closed senses, amidst the loveliness of nature.

...As regards the good principle, the same conception prevailed over all the Christian countries of Europe. The Roman Catholic Church took care of that, and whoever deviated from the prescribed faith was a heretic. But in relation to the evil principle and the empire of Satan, different views were held in different countries, and the Germanic North had quite different conceptions from the Latin South. This was caused by the fact that the Christian priesthood did not reject the previously existing national gods as baseless fantasies of the brain, but conceded to them an actual existence; asserting, however, that all these gods were nothing but male and female devils, who, through the victory of Christ, had lost their power over mankind, and now sought through wiles and stratagems to lure them to sin. All Olympus was now transformed into an airy hell; and if a poet of the middle ages sang of Grecian mythology ever so beautifully, the pious Christian would persist in seeing therein only devils and hobgoblins. The gloomy fanaticism of the monks alighted with special severity on poor Venus: she was considered a daughter of Beelzebub, and the good knight Tannhäuser tells her to her face—

"O Venus, lovely wife of mine,
You are but a she-devil!"

Tannhäuser had been enticed by her into that wondrous mountain-cavern called the Venusburg, where, according to tradition, dwelt the beautiful goddess with her nymphs and her paramours, beguiling the hours with the most wanton carousings and dancing. Even poor Diana was not spared, and, notwithstanding her previous reputation for chastity, similar scandals were fastened on her good name. It is said that she, together with her nymphs, indulged in nightly rides through the forest; hence the legend of a strange midnight chase, by wild and furious hunters. This legend reveals clearly the then pervading Gnostic theory of the degeneration of the former divinities. In this transformation of the ancient national religion the underlying principle of Christianity is most fully manifested. The national religion of Europe in the North, even more than in the South, was pantheism. All the mysteries and symbols of that religion were founded on and had reference to a worship of nature; each of the elements was regarded as the embodiment of some mysterious being, and as such was revered and worshipped; in every tree dwelt a divinity, and all nature swarmed with gods and goddesses. Christianity exactly reversed this, and in place of gods it substituted devils and demons. The cheerful figures of Grecian mythology, beautified as they were by art, had taken root in the South along with Roman civilisation, and were not so easily to be displaced by the hideous, weird, and satanic divinities of the German North. The latter seemed to have been fashioned without any particular artistic design, and even before the advent of Christianity they were as sombre and as gloomy as the North itself. Hence there could not arise in France so frightful a devil-dom as among us in Germany, and even the witchcraft and sorcery of the former assumed a cheerful guise. How lovely, fair, and picturesque are the popular superstitions of France as compared with the bloody, hazy, and misshapen monsters which loom gloomily and savagely from out the mists of German legendary lore!

Those German poets of the middle ages who chose such themes as had originated, or been first treated, in Brittany and Normandy, thereby invested their poems with somewhat of the cheerfulness of the French temperament. But the old Northern sombreness, of whose gloom we can now scarcely form any idea, exercised full sway over such of our literature as was distinctly national, and over such popular traditions as have been orally transmitted. The superstitions of the two countries offer as striking a contrast as that which exists between a Frenchman and a German. The supernatural beings that figure in old French fabliaux and legends are bright and cheerful creations, and remarkable for a cleanliness which is noticeably lacking in our filthy rabble of German hobgoblins. French fairies and sprites are as distinguishable from German spectres as a spruce and daintily-gloved dandy, jauntily promenading the Boulevard Coblence, is different from a burly German porter, carrying a heavy load upon his shoulders. A French nixen, such as a Melusina, is to a German elf as a princess to a washerwoman. The fay Morgana would stand aghast at sight of a German witch, her body naked and besmeared with ointment, riding on a broom-stick to the Brocken. The Brocken is no merry Avalon, but a rendezvous for all that is weird and hideous. On the very summit of the mountain sits Satan, in the shape of a black goat. The infamous sisterhood form a circle around him and dance, and sing, "Donderemus! Donderemus!" Mingled in the infernal din are heard the bleating of the goat and the shouting of the demoniac crew. If, during the dance, a witch happens to drop a shoe, it is an evil omen, and portends that she will be burned at the stake ere the year ends. But all the terror which such a portent inspires is forgotten amid the wild and maddening Berlioz-like music of the witches' sabbath—and when in the morning the poor witch awakens from her delirium, she finds herself lying, stark naked and tired, by the glimmering embers of her hearth.

The most complete account of witches we find in the learned Dr. Nicolai Remigius's Demonology. This sagacious man had the best opportunity to learn the tricks of witches, as he officiated at their trials, and during his time, in Lotharingia alone, eight hundred women were burned at the stake, after trial and conviction. The trial was generally as follows:—Their hands and feet were tied together, and then they were thrown into the water. If they went under and were drowned, it was a proof that they were innocent, but if they floated on the surface, they were recognised as guilty and burned. Such was the logic of those times.... When the learned Dr. Remigius had completed his great work on witchcraft, he deemed himself so great a master of his subject as to be able to work magic, and, conscientious man that he was, did not fail to accuse himself before the courts; in consequence of which accusation he was burned as a sorcerer.

...I must confess that Luther did not understand the real nature of Satan. Whatever evil may be said of the devil, it cannot be denied that he is a spiritualist. Still less did Luther understand the real nature of Catholicism. He did not comprehend that the fundamental idea of Christianity, the deadening of the senses, was too antagonistic to human nature to be ever entirely practicable in life; he did not comprehend that Catholicism was a concordat between God and the devil—that is to say, between the spirit and the senses, in which the absolute reign of the spirit was promulgated in theory, but in which the senses were nevertheless practically reinstated in the enjoyment of their rights. Hence a wise system of concessions allowed by the Church to the senses, always, however, under formalities which cast a slur on every act of the senses, and maintained the sham usurpation of the spirit. You might yield to the tender impulses of your heart and embrace a pretty girl, but you must confess that it was a flagrant sin, and for this sin you must make atonement. That this atonement might be made with money was as beneficial to humanity as useful to the Church. The Church imposed fines, so to say, for every indulgence of the flesh; hence there arose taxes on all sorts of sins, and there were pious colporteurs who, in the name of the Roman Catholic Church, hawked for sale through the land absolutions for every taxed sin. Such a one was that Tetzel against whom Luther first entered the field.

...Leo X., the keen Florentine, the pupil of Politian, the friend of Raphael, the Greek philosopher with the triple crown, bestowed by the Conclave, probably because he suffered from a disease, nowise due to Christian abstinence, which was then very dangerous, Leo of Medici, how he must have smiled at the poor, chaste, simple-minded monk who imagined that the evangelic gospels were the chart of Christianity, and that this chart must be a truth! Perhaps he never comprehended what Luther was aiming at, for at that time he was busily occupied with the building of St. Peter's Cathedral, the cost of which was defrayed by the money derived from these sales of absolutions, so that sin actually furnished the means wherewith to build this church, which became thereby, as it were, a monument to the lusts of the flesh, like that pyramid which an Egyptian girl built with the money she had earned by prostitution. Of this house of God it perhaps might be said more truly than of Cologne Cathedral, that it was built by the devil. This triumph of spiritualism, compelling sensualism itself to build its most beautiful temple—this reaping from the multitude, by concessions made to the flesh, the means wherewith to beautify spiritualism, was not understood in the German North. For there, more easily than under the burning skies of Italy, was it possible to practice a Christianity that should make the fewest concessions to the senses. We Northerners are cold-blooded, and needed not so many price-lists of absolution for sins of the flesh as the fatherly Leo sent us. The climate makes the exercise of Christian virtues easier for us; and when, on the 31st of October 1517, Luther nailed to the door of St Augustine's Church his thesis against indulgences, the city moat of Wittenberg was, perhaps, already frozen over with ice thick enough for skating, which is a chilly pleasure, and therefore no sin.
