  After Sabbatai Zevi's decision, under duress, to convert to Islam and remain under the protection of the Sultan (where he died a decade later) his disciples split into “moderate” and “radical” camps. The moderates held that they should remain Jews, even observant ones, and keep their faith in Sabbatai Zevi as a secret doctrine. The “radicals” held they must imitate their master and thus convert to Islam to continue the redemptive process. Included in this radical camp was Jacob Frank (1726–1791) (about whom Scholem had little to say) who, with most of his disciples, converted to Catholicism in 1759. The radicals did not present much of a problem for the Jews as they disappeared from the community. The moderates, however, presented a grave problem and inspired a whole industry of Sabbatean hunting that extended into the 19th century. The point in all this, according to Scholem, is that Sabbateanism destroyed Jewish tradition from within a century before the Enlightenment, and may have even brought the latter into existence.
