Oahspe, which I quoted in the previous post, was written by a man who claims to have sat in front of his typewriter and let angels control him. It claims to be a revelation from God ("Jehovih") about the spiritual history of the world and all the ethereal beings who have ruled it through the ages. Yet in it God says the following:

"Of all things, therefore, man should learn, especially of what he can see, and hear, and prove, rather than of spirits whom he cannot prove, nor find when he wanteth them."
