Even before the destruction of the Temple in 70 C.E., the Jews of the Greco-Roman Diaspora successfully created Judaic systems that provided them with identity, purpose, new ways of thinking, and alternative points of access to the divine, independent of the Temple rituals in far-off Jerusalem.
2 Maccabees (ca. 1st cent. B.C.E) presents Judaism as the antithesis to Hellenism. A century or so later, however, 4 Maccabees uses Hellenistic ideas to encourage Jews to hold fast to their ancestral faith.
On Chanukah we celebrate the miraculous military victories of the “few over the many,” and of Jewish culture over Greek. Ironically, however, Chanukah has also bequeathed to us a new genre of Jewish literature, one that has been in frequent use ever since: Greek-style stories of bravery in defeat and dying for the cause.
