The Celestial Hierarchy

This also is worthy, I think, of intellectual consideration, that the scriptural tradition respecting the Angels gives their number as thousands of thousands and ten thousand times ten thousand, multiplying and repeating the very highest numbers we have, thus clearly showing that the Orders of the Celestial Beings are innumerable for us; so many are the blessed Hosts of the Supermundane Intelligences, wholly surpassing the feeble and limited range of our material numbers. And they are definitely known only by their own supermundane and celestial Intellect and the knowledge which is granted to them allbounteously by the All-knowing Mother-Wisdom of the Most High God, which is superessentially at once the substantiating Cause, the connecting Power, and the universal Consummation of all principles and things.
