In 1865, having already preached before the Emperor of the French in Paris, and been greatly commended by the most distinguished people there, both French and foreigners, he was called to Vienna, where his family resides, and where all his former associates and co-religionists awaited him with the greatest curiosity and interest. The six lectures or discourses he gave in the _Schotten-Kirche_, opposite his brother’s residence, at which he was an honored and _fêted_ guest, were attended by crowds of his own Jewish friends, besides all the _élite_ of Viennese and foreign society. The impassioned tone of his voice, his closely knit arguments, the air of apostleship about his slight figure and pale, inspired face, the presence of his nearest and dearest relations, and, above all, his own position toward them, in the very centre of his youthful Revolutionary triumphs--all concurred in making this short station of Advent one of thrilling interest. At the end of each sermon, or _conférence_, as the French say (they were delivered in French, which is like a second mother-tongue to Marie-Bernard Bauer), he addressed a prayer to God, and, while the language of each succeeding discourse increased in sublimity, that of the concluding prayers seemed to take such flights of unparalleled grandeur that the audience could only kneel in motionless attention and unbroken silence for some minutes after the preacher had ceased to speak--the highest tribute, perhaps which an impressed people can offer to an orator. Marie-Bernard Bauer has since received the Roman title of Monsignore, and been appointed chaplain to the Emperor of the French. He accompanied the Empress Eugénie to the opening of the Suez Canal, and preached a magnificent sermon on the occasion, in presence of the assembled potentates. But whatever else he has done, whatever else he may be destined to do in the future, he will scarcely be able to surpass his admirable achievements of the Advent station of 1865, when he became, as it were, the champion and apologist of Christianity before one of those representative Jewish assemblies which contained within itself so much enlightenment, so much talent, and so much successful individuality. At the time when he preached these sermons, of which we will now endeavor to give some idea, as far as a translation will allow, he was only thirty-six years of age, and his frail, delicate body made him seem even younger. The following is the third in order of the _Conférences_, and was preached on the 17th of December, 1865. The text is given entire, and the subject, as expressed in the published edition of these sermons, was: CHRISTIANITY AS A HISTORICAL FACT.
