Jacob Frank

Jacob Joseph Frank was a Polish-Jewish religious leader who claimed to be the reincarnation of the self-proclaimed messiah Sabbatai Zevi (1626–1676) and also of the biblical patriarch Jacob. The religious authorities of the Jewish community excommunicated Frank and his followers due to his heretical doctrines that included deification of himself as a part of a trinity and other controversial concepts such as neo-Carpocratian "purification through transgression". Frank’s teachings led his sect into scandalous practices, including ritualized orgies, incestuous acts—most notably between fathers and daughters—and the deliberate violation of Jewish moral laws, which he preached were necessary to hasten a messianic redemption through embracing the "abyss" of sin.
