Jacob Frank's route from heresy to baptism
Jacob Frank was a Podolian Jew who led a Sabbatean sect. His followers were excommunicated by the rabbis, and at the Kamieniec disputation of 1757 they sided with Bishop Dembowski, who then ordered the Talmud burned. After the 1759 Lwów disputation, the Frankists were baptized as Catholics en masse, with King Augustus III as Frank's godfather, yet the Church soon imprisoned Frank for heresy at Częstochowa for thirteen years, and his followers reread the imprisonment as a necessary stage of his messianic mission.
