The Cabala, or oral tradition, is, according to the Jews, a perpetual divine revelation, preserved among the Jewish people by secret transmission. It sometimes denotes the doctrines of the prophets, but most commonly the mystical philosophy, which was probably introduced into Palestine from Egypt and Persia. It was first committed to writing in the second century A.D. The Cabala is divided into the symbolical and the real, of which the former gives a mystical signification to letters. The latter comprehends doctrines, and is divided into the theoretical and practical. The first aims to explain the Scriptures according to the secret traditions, while the last pretends to teach the art of performing miracles by an artificial use of the divine names and sentences of the sacred Scriptures. The Jews of the Middle Ages acquired great reputation for learning, especially in Spain, where they were allowed to study astronomy, mathematics, and medicine in the schools of the Moors. Granada and Cordova became the centres of rabbinical literature, which was also cultivated in France, Italy, Portugal, and Germany. In the sixteenth century the study of Hebrew and rabbinical literature became common among Christian scholars, and in the following centuries it became more interesting and important from the introduction of comparative philology in the department of languages. Rabbinical literature still has its students and interpreters. In Padua, Berlin, and Metz there are seminaries for the education of rabbins, which supply with able doctors the synagogues of Italy, Germany, and France. There is also a rabbinical school in Cincinnati, Ohio. The Polish rabbins and Talmudists, however, are the most celebrated. 15. THE NEW REVISION OF THE BIBLE.--The convocation of the English House of Bishops, which met at Canterbury in 1870, recommended a revised version of the Scriptures, and appointed a committee for the work of sixty-seven members from various ecclesiastical bodies of England, to which an American committee of thirty-five was added, and by their joint labors the revised edition of the New Testament was issued in 1881. The revised Old Testament is expected to appear during 1884. The advantages claimed for these new versions are: a more accurate rendering of the text, a correction of the errors of former translations, the removal of misleading archaisms and obsolete terms, better punctuation, arrangement in sections as well as chapters and verses, the metrical arrangement of poetry, and an increased number of marginal readings.
