According to the opinion of Bernays, the Hebrew cult differed from that of the heathen, and was intended to be a contrast. Idolatry expressed itself in plastic, Judaism in ritual, symbolism. Therefore the very aspect of Judaism which the reformers desired to abolish as unfitting and unworthy, should be preserved. Everything which in the course of Jewish history had been assimilated and developed, according to Bernays, ought to have a place assigned to it, being a necessary part of the whole,—even Talmudism and the Kabbala.

This book contains many immature and unpolished ideas, much that borders on the ridiculous. But if the author only succeeded in awakening the idea that Judaism has an historical mission as an apostle to the nations, it should suffice to procure for him a place of honor in the records of Jewish history. Not that he could claim this as a new discovery, for the text-book of Judaism plainly points to it. It is the essence of the messages proclaimed by the prophets. It has been verified by history, that European and Asiatic nations have been delivered from their darkness by the light that came from Judaism. But the accumulated sufferings of the Jews, and the servile form assumed by Judaism, had caused this fact to be so entirely forgotten, that its own sons had no idea thereof. The merit of the man who again called it to mind is therefore of no mean degree.

The extraordinary talents and original ideas of Bernays directed the attention of Jewish society to him. Afterwards, it is true, he denied the authorship of the "Biblical Orient"; but if he did not actually compose it, he might have done so, for it is flesh of his flesh, or spirit of his spirit.

The Hamburg community, which sorely needed a power to withstand the Temple Union, in consequence of his renown chose Bernays for their spiritual guide. It was a good move on their part, and bore important results. The rabbis of the old school were ill prepared for the contest between two justifiable principles, the preservation of Judaism in its peculiar manifestations, and the assimilation of European culture by the Jews. Their weapons had grown rusty, and injured the owners more than their opponents. Fresh forces were therefore required in their cause—men cognizant of the wants of the age, who could utilize them for the honor and purification of Judaism. The appointment of Bernays to the Hamburg rabbinate (November, 1821) created a stir: he was the first rabbi with a well-ordered secular education. It was a sign of the times that he dispensed with the title of rabbi and preferred to be called Chacham, as was customary among the Portuguese Jews: he did not wish the despised title of rabbi to be a hindrance to his activity. True to his aversion for slavish imitation, he eschewed all clerical mummery in costume and gestures, to which the reform preachers attached great importance in the pulpit. Bernays did not claim to be the guardian of souls, only the teacher of his congregation. He also delivered sermons, but the contents, form, and other details differed entirely from those introduced by the Jacobson school. Owing to his peculiar mode of thought, his addresses were not understood by the multitude; but thoughtful hearers at least conceded to him the merit of originality, which contrasted favorably with the insipidity of the Temple preachers. When Heine, who at this time was still interested practically in Judaism, was staying in Hamburg, he was induced to hear Bernays' sermons, and to compare them with those of other preachers. Heine understood the method and form of his thoughts, and the opinion of the lyrical satirist ran as follows:

"I have heard Bernays preach ..., none of the Jews understand him, he desires nothing for himself, and will never play any other part; but he is a man of mind, and has more life in him than Kley, Salomon, and Auerbach I and II."

By unobtrusive work, Bernays succeeded in gaining the respect, not only of the community, but also of the rigidly pious party elsewhere. Their suspicious natures found nothing to blame in the religious conduct of the Chacham. The changes that he introduced, in reality reforms, met with approval and imitation in orthodox congregations. By his penetration and his great erudition he exercised deep influence over the rising generation, to whom he opened up the rich treasures of Jewish literature, then but little known. He thereby imbued his disciples with joyous attachment to Judaism. As already stated, he did not care for writing. If his courage had kept pace with his knowledge and wealth of ideas, his activity would have had greater influence on modern Jewish history.

In another quarter, an equally beneficent and elevating, though differently constituted, personality, was at work. Isaac Noah Mannheimer (born at Copenhagen, 1793; died at Vienna, 1864), originally a disciple of the school of Jacobson, softened its crudities, and so caused the offensive alterations in the divine service to be received favorably; he struck the right note when making improvements. He may justly be considered the incarnation of Jewish refinement—every inch a man. In him the essential elements of peculiarly Jewish culture were harmoniously combined with the attractive forms of European civilization; indeed, in every respect his was a perfectly moulded nature. Gifted with genial humor and wit, enthusiasm and discretion, leading an ideal life, and possessing a sure practical instinct, endowed with poetic talents and sober thought, with childlike tenderness and cutting satire, great eloquence and earnest vigor, deep love of Judaism and delight in modern ideas—he combined these varied characteristics in the happiest manner. These brilliant qualities, together with his nobility of soul and disinterestedness, devotion to his convictions, and conscientiousness in all official duties, his delicacy of feeling, tact, aversion to vulgarity and forbearance with the vulgar—swiftly captivated all hearts, attracted the noble-minded, and even filled the unworthy with respect, and thus lightened his labors. Born and bred under the mild Danish government, which at an early date had granted equal rights to Jews, nor, like other states, withdrew or abridged them when circumstances changed, Mannheimer from childhood learned to hold his head high, and to represent his co-religionists and utter his convictions without fear even in a country where a servile conception of the position of burgesses, peasants, and especially of the Jews, long prevailed. Mannheimer did not possess original ideas or deep knowledge of Jewish literature; but he was powerfully swayed by his own convictions, which he cherished and disseminated, not hiding them away as buried treasures. This man of words and action was placed by destiny in a situation, where his peculiar nature and special gifts could find scope, and ennoble wide circles. Everyone cognizant of the state of affairs then prevailing in Austria, and the extent to which the Austrian Jews have since progressed, must confess that Mannheimer was providentially fitted for his position in the Austrian capital, on the boundary-line of semi-barbarous countries, to raise the Jews of those lands from the moral degeneracy into which they had been plunged as much by Joseph II's benevolent despotism as by his mother's hostility, and to repair the harm caused by the Herz Hombergs, the Peter Beers, and the whole troop of so-called "Normal teachers" and official religious instructors.

A chief who, in face of constant strife and danger, founds a colony with a band of half savage men, elevates it, and trains it to be a pattern to others, can claim no greater praise than Mannheimer deserved in founding the congregation of Vienna. The camp of Metternich and Francis I tolerated no Jews within its domains; only by way of exception a few rich families with their dependents were tolerated under various extraordinary titles. These favored families had immigrated from various countries, were in no way connected, had no rights as a community, could not possess a synagogue, nor appoint a rabbi; in short, by law almost everything was forbidden to them as a religious body. Nevertheless, certain adventurous persons amongst them desired to introduce a German order of service, founded on the model of the Hamburg Temple, and their efforts were alternately encouraged and frustrated by the government. When these enlightened men in Vienna undertook to build a Temple, they secured the aid of Mannheimer as preacher (June, 1825), but were compelled to evade the restrictive laws by inventing some insignificant title for him, so that he might be allowed to reside in Vienna.

Although Mannheimer was intimate with David Friedländer, Jacobson, and the young iconoclasts with whom destruction of the old Judaism was a principle, and had occasionally preached in the Reform synagogues of Berlin, Hamburg, and Leipsic, yet he was not so strongly attached to the new system that he did not recognize its fundamental errors. His first and his last word in his new sphere of action was that no rupture should be caused between Jews, no sectarianism should be encouraged, and that the old orthodox party should not be offended and repelled by daring movements, but should gradually be won over to the new forms. Actuated by these ideas, he carried a moderate change in the synagogue service, in opposition to the wishes of the man who had promoted him to his office. Mannheimer in the new synagogue removed only offensive excrescences, making the service dignified, and animating it by his impressive words, but he retained the Hebrew language, that strong bond of union, and, to the regret of his former brother reformers, dispensed with the organ and German hymns. Even more successfully than Isaac Bernays did Isaac Mannheimer pave the way to the reconciliation of old and new ideas.

In his pulpit eloquence, acknowledged by competent judges, Jews and Christians, to be of high quality, his power of harmoniously combining two apparently hostile elements was displayed. Mannheimer had discovered a noble treasure in Jewish literature and profited richly by it. In the Talmud and Agada—a mine of thoughtful sayings, parables, riddles, interesting observations and witty play upon words—he made himself thoroughly at home, discovered the golden grain, or, to speak more accurately, knew how to extract a pleasing meaning from the most insignificant saying, and employed the remarks of the old Agadists as interpreters of new views and thoughts. By utilizing the Agadic elements, his method of preaching acquired a peculiar character, and exercised strong attraction over the pious Jews and the rising generation. Portuguese Jews (Franks), who had migrated from Turkey to Vienna, also listened with pleasure to this lively and spirited preacher. The East and West were united in Mannheimer and in the new Viennese Temple, consecrated April, 1826. As if the congregation of this Temple were intended from the outset to complete the work of propitiation between old and new forms, they succeeded in securing the services of Sulzer, a skilled musician, who with his wealth of musical resources endowed the Hebrew prayers with almost magical expressiveness, and transformed the old objectionable intoning into soul-stirring melodies. These melodies rendered an organ superfluous. The soft, swelling chorals and solos of the Viennese Temple, as also Mannheimer's sermons, proved that the old possessions were not utterly useless, as violent reformers had represented them to be, but only required modifying to be impressive. Pulpit and choir, working in accord, produced great effect upon the minds of the growing congregation of Vienna, whose affection for inherited Judaism, and reverence for Jewish antiquity were combined with a desire to satisfy the demands of progress. Mannheimer's personality served to strengthen the feeling so awakened. In the pulpit, as in household and social affairs, he appeared, not as a guardian of souls, as a clergyman, or priest—he abominated a sanctimonious, unctuous manner—but as a tender father, as a friend, adviser, and help. As he did not shrink from censuring the objectionable side of old and new customs, he educated, by word and example, a pattern community in which each individual strove to maintain peace and suppress dissension.
