As I said, your thesis leaves on with a lot to think about:
Your thesis gives me occasion to articulate _my_ thesis.
Most important, to my mind, is your discovery of
the importance of the Mosaic.
prohibition against imagery
This prohibition is to my thinking conjoined
with the prohibition against uttering his name. 
The name is a representation of the object named.
That which is pictured becomes by virtue of its being depicted
the object of worship.
That which is named becomes objective,
at least to the extent.
that the name enables two or more persons
to talk about it.
All pictorial art strives to be
must be considered
imagery of the divine,
prohibited, because the divine
defies representation.

I consider the prohibition of uttering his name the discovery
or invention of humanness; because with the encounter
at the burning bush the awareness of the divine, now unutterable,
became inward, became subjective. At the burning bush, man
himself became divine, because ever after, the divine was within.
That prohibition of uttering his name,
I consider not only the focus of Judaism, but the focus of humanity.
That prohibition, properly understood,
liberates us from all public worship,
and all public religions, including Judaism itself.

I may have mentioned to you, that I interpret the
Mosaic command to fashion brazen images of poisonous snakes,
that whoever gazes upon them should be immunized against
their venom.
It is obviously a repudiation of the image-prohibition.
I consider it the legitimization of art.
