To say that God “has no name,” or that He has only “the name above every name,” is a way of summarizing this fundamental aspect of Biblical revelation. Nor is it a coincidence that the revelation (or non-revelation) of the divine name occurs at the burning bush.
If there is to be a vision of the divine essence in the afterlife, then God is in Himself intrinsically intelligible, however much we may be unable to apprehend Him in our current state. The locus of mystery in God accordingly shifts from God Himself to the limitations of our current bodily and temporal ways of knowing.
