A revelatory account of a spiritual leader who dared to assert the value of rabbinic doubt in the face of messianic certainty

In 1665, Sabbetai Zevi, a self-proclaimed Messiah with a mass following throughout the Ottoman Empire and Europe, announced that the redemption of the world was at hand. As Jews everywhere rejected the traditional laws of Judaism in favor of new norms established by Sabbetai Zevi, and abandoned reason for the ecstasy of messianic enthusiasm, one man watched in horror. Dissident Rabbi tells the story of Jacob Sasportas, the Sephardic rabbi who alone challenged Sabbetai Zevi's improbable claims and warned his fellow Jews that their Messiah was not the answer to their prayers.

Yaacob Dweck's absorbing and richly detailed biography brings to life the tumultuous century in which Sasportas lived, an age torn apart by war, migration, and famine. He describes the messianic frenzy that gripped the Jewish Diaspora, and Sasportas's attempts to make sense of a world that Sabbetai Zevi claimed was ending. As Jews danced in the streets, Sasportas compiled The Fading Flower of the Zevi, a meticulous and eloquent record of Sabbatianism as it happened. In 1666, barely a year after Sabbetai Zevi heralded the redemption, the Messiah converted to Islam at the behest of the Ottoman sultan, and Sasportas's book slipped into obscurity.

Dissident Rabbi is the revelatory account of a spiritual leader who dared to articulate the value of rabbinic doubt in the face of messianic certainty, and a revealing examination of how his life and legacy were rediscovered and appropriated by later generations of Jewish thinkers.
