This leads to the epistemological element of theistic belief.
The belief of god is basically the unknowable is the most important epistemological element of theistic belief.
Religious agnosticism suffers from the obvious flaw that one cannot possibly know that something exists without some knowledge of what it is that exists. If god is unknowable, the concept of "god" is totally devoid of content, and the word "god" becomes a meaningless sound. To state that god exists-where "god" represents an unknown, a blank- is to say nothing whatsoever.
Religious agnosticism is predicated on the concept of the "unknowable," and herein lies the root of its irrationality. To posit the existence of something which, by its nature, cannot be known to man is to submerge oneself in the hopeless contradictions.
First we must ask our self: If god cannot be known, how can god be known to exist?
Second, if god cannot be comprehended, then none of his attributes can be known-including the attribute of incomprehensibility. To state that something is by nature unknowable is to pronounce knowledge of its nature, in which case we are again involved in a contradiction.
When one claims that something is unknowable, can one produce knowledge in support of this claim? If one can't, then one's insertion is arbitrary and utterly without merit. If one can, one has accomplished the impossible: one has knowledge of the unknowable.
Third, to support the existence of the unknowable not only presupposes knowledge-it presupposes omniscient knowledge. To claim that god is incomprehensible is to say that one's concept of god is unintelligible, which is to confess that one does not know what one is talking about.
By criticizing the notion of an unknowable being, we have indirectly destroyed the concept of a supernatural being.
