I think those Greek Thinkers were ahead of their time, the ones looking for a less "material" view of gods. Prior to them, and ever after, the Anthropomorphising of gods went on.
The gods and goddesses who came to Israel via Canaan and ultimately Sumer, were VERY human in their actions, having huge Banquets, Drinking Parties, and of course having copious sexual encounters and unions, the god El being particularly randy with two goddesses at one time !
Christians today cannot manage, no matter how they try, not to anthropomorphise their god at least in some way, but the N.T does , "Revelation" talking of god's "Hand" etc.
I think the gods are far more appealing as characters when we envisage them as supernatural beings, but being very human in so many ways, even YHWH is a much more sympathetic character when we think of him being in Love, albeit with Israel, or being saddened, or enjoying a good meal of sacrificed meat and so on.
Therefore I can see the difficulty that those who advocate for a more mystical version of god, we puny humans cannot stop thinking of our gods, and depicting them in Art, as very human in most ways.
