Book of Classical Hymns
"But, let the rule of the Oracles be here also prescribed for us, that we shall establish the truth of the things spoken concerning God, not in the persuasive words of man’s wisdom, but in demonstration of the Spirit-moved power of the Theologians, by aid of which we are brought into contact with things unutterable and unknown, in a manner unutterable and unknown, in proportion to the superior union of the reasoning and intuitive faculty and operation within us. By no means then is it permitted to speak, or even to think, anything, concerning the superessential and hidden Deity, beyond those things divinely revealed to us in the sacred Oracles. For Agnosia of its superessentiality above reason and mind and essence— to it must we attribute the superessential science, so far aspiring to the Highest, as the ray of the supremely Divine Oracles imparts itself, whilst we restrain ourselves in our approach to the higher glories by prudence and piety as regards things Divine."
