the Works of Dionysius the Areopagite - On Divine Names - Chapter 01 - Section 6

6. For instance, they call It Nameless when they say that the Supreme Godhead Itself, in one of the mystical visions whereby It was symbolically manifested, rebuked him who said: “What is thy name?” and, as though bidding him not seek by any means of any Name to acquire a knowledge of God, made the answer: “Why askest thou thus after My Name seeing it is secret?” Now is not the secret Name precisely that which is above all names and nameless, and is fixed beyond every name that is named, not only in this world but also in that which is to come? On the other hand, they attribute many names to It when, for instance, they speak of It as declaring: “I am that I am,” or “I am the Life,” or “the Light,” or “God,” or “the Truth,” and when the Inspired Writers themselves celebrate the Universal Cause with many titles drawn from the whole created universe, such as “Good,” and “Fair,” and “Wise,” as “Beloved,” as “God of Gods” and “Lord of Lords”, and “Holy of Holies,” as “Eternal,” as “Existent” and as “Creator of Ages,” as “Giver of Life,” as “Wisdom,” as “Mind,” as “Word,” as “Knower,” as “possessing beforehand all the treasures of knowledge,” as “Power,” as “Ruler,” as “King of kings,” as “Ancient of Days;” and as “Him that is the same and whose years shall not fail,” as “Salvation,” as “Righteousness,” as “Sanctification,” as “Redemption,” as “Surpassing all things in greatness,” and yet as being in “the still small breeze.” Moreover, they say that He dwells within our minds, and in our souls and bodies, and in heaven and in earth, and that, while remaining Himself, He is at one and the same time within the world around it and above it (yea, above the sky and above existence); and they call Him a Sun, a Star, and a Fire, and Water, a Wind or Spirit, a Dew, a Cloud, an Archetypal Stone, and a Rock, and All Creation, Who yet (they declare) is no created thing.
