Exactally, the greeks may have respect the philosophy of the jews, but they didn't concern themselves with the theology. That is why I said jewish theology was inconsequential to aristotle, he didn't come to formulate his theories as a refutation of the jewish god out of denial of the "truth as told in the sacred writings of Moses and the Prophets" to use best's terminology.
And the ancient greeks did have quite a bit to say on metaphysics, Aristotle wrote an entire book on the topic which is where the "unmoved mover" theory comes from. Plato's views on metaphysics are labled Platonic Realism and deal with the theory there is a distinct seperation of the perceptual world and nonperceptual world with sub seperations of actual and reflected forms.
While the majority of greek philosophy does pertain to social and political writings, they did spend sometime on metaphysics and alot of western philosphy on the subject has roots in those theories.
