I am deeply mistrustful of "revelations" from the divine that come in the form of concepts or words.

As a compulsive rationalist, I would tend to agree with you. Language (at least for me) seems often to trip me up into the "What The Thinker Thinks, The Prover Proves" trap. Not to say that I haven't spilt endless ink trying to philosophize and explicate my conceptions of (t)ruth, but for the most part I think the Numinous must remain an experiential thing. Or, to let Chuang Tzu show me up: "The Tao which can be expressed is no longer the Tao."
