What is Jewish about Polydox Judaism?
4A. Once it is recognized that there have been a series of new and different Jewish religions over the ages, this question can be answered simply. A religion is Jewish, that is, a religion is a “Judaism,” if it has been created by Jews as the religious expression of their Jewishness. New Jewish religions or Judaisms arise when Jews of some particular age find that the Judaism they have inherited is no longer responsive to their ultimate concerns. Based on the realities of Jewish history, the rule can be laid down that all given “Judaisms” of an age are those that Jews of the age say they are.
