the Works of Dionysius the Areopagite - On Divine Names - Chapter 01 - Section 8

8. Moreover, the sacred writers proclaim not only such titles as these (titles drawn from universal or from particular providences or providential activities), but sometimes they have gained their images from certain heavenly visions (which in the holy precincts or elsewhere have illuminated the Initiates or the Prophets), and, ascribing to the super-luminous nameless Goodness titles drawn from all manner of acts and functions, have clothed It in human (fiery or amber) shapes or forms, and have spoken of Its Eyes, and Ears, and Hair, and Face, and Hands, and Wings, and Feathers, and Arms, and Back Parts, and Feet; and fashioned such mystical conceptions as its Crown, and Throne, and Cup, and Mixing Bowl, etc., concerning which things we will attempt to speak when we treat of Symbolical Divinity. At present, collecting from the Scriptures what concerns the matter in hand, and employing as our canon the rule we have described, and guiding our search thereby, let us proceed to an exposition of God’s Intelligible Names; and as the Hierarchical Law directs us in all study of Divinity, let us approach these godlike contemplations (for such indeed they are) with our hearts predisposed unto the vision of God, and let us bring holy ears to the exposition of God’s holy Names, implanting holy Truths in holy instruments according to the Divine command, and withholding these things from the mockery and laughter of the uninitiate, or, rather, seeking to redeem those wicked men (if any such there be) from their enmity towards God. Thou, therefore, O good Timothy, must guard these truths according to the holy Ordinance, nor must thou utter or divulge the heavenly mysteries unto the uninitiate. And for myself I pray God grant me worthily to declare the beneficent and manifold Names of the Unutterable and Nameless Godhead, and that He do not take away the word of Truth out of my mouth.
