“Book Descriptions: "Jacob Frank, one of the most unexpected, shocking, original, and misunderstood figures in Jewish history, stirred up the Jewish world from the margins of heresy to the center of broad messianic movement that engaged thousands of followers in the mid-eighteen century, by crossing every traditional border of the Jewish community. Now, for the first time, The Heresy of Jacob Frank provides a groundbreaking book-length analysis of Frank's outrageous and innovative religious ideas, based on close readings of his recorded oral teachings. Dr. Michaelson's brilliant work is a major achievement in the scholarship of Frankism, Sabbateanism and Jewish mysticism, as well as an engaging and surprising tale of a man who transgressed every boundary he came across. Highly recommended." -- Rachel Elior, John and Golda Cohen Professor Emerita of Jewish Philosophy, The Hebrew University of Jerusalem” DRIVE
