If the later datings of the book (e.g. Hellenistic period) some people call the Hebrew Bible and others call the Old Testament (etc) are accepted, then can the case be made that its very formation was (partly) justification for Jewish identity or at least an assumption of Jewish identity?
If earlier datings are accepted (say pre-Hellenistic), is the attribution of specifically Jewish identity something involved in the later canonising?
Or, is something we roughly call Jewish identity much earlier than the Hellenistic period, even if a certain crystallization occurred from the Maccabees onwards?
And from which time period can we start talking about recognisably ‘Jewish identity’?
And presumably all those tricky questions of historicity of the major stories will play a role, will they not?
(For those who prefer other terms, e.g. ‘Judean’, substitute accordingly if meant as roughly synonymous)
