The Rambam understands this verse to mean simply that God has no character trait that one could ascribe to anything physical. Thus God has no form, no matter, no substance, no "essence" or anything else that could be ascribe to any physical being.
This is well known and common place, but in the Jewish religious world in the next breath, people will start to talk about God as if he has characteristics that could apply to physical beings or things.
Thus the basic beliefs are self contradictory, and therefore false.
I mean to say that if God would have any form or substance, then there would be things [Heaven forbid] that one could compare Him to. Therefore nothing that one can attribute to a physical being can be applicable to God.
With the religious this change in the belief system of Torah goes along with worship of their religious teachers. They ascribe Divine traits to their leaders. Thus this change in the philosophy of Torah goes along with a hidden agenda. It is not an innocent mistake.
