XXIX. Who spread the sky around us, and set the stars in order? Or rather, first, can you tell me, of your own knowledge of the things in heaven, what are the sky and the stars; you who know not what lies at your very feet, and cannot even take the measure of yourself, and yet must busy yourself about what is above your nature, and gape at the illimitable? For, granted that you understand orbits and periods, and waxings and wanings, and settings and risings, and some degrees and minutes, and all the other things which make you so proud of your wonderful knowledge; you have not arrived at comprehension of the realities themselves, but only at an observation of some movement, which, when confirmed by longer practice, and drawing the observations of many individuals into one generalization, and thence deducing a law, has acquired the name of Science (just as the lunar phenomena have become generally known to our sight), being the basis of this knowledge. But if you are very scientific on this subject, and have a just claim to admiration, tell me what is the cause of this order and this movement. How came the sun to be a beacon-fire to the whole world, and to all eyes like the leader of some chorus, concealing all the rest of the stars by his brightness, more completely than some of them conceal others. The proof of this is that they shine against him, but he outshines them and does not even allow it to be perceived that they rose simultaneously with him, fair as a bridegroom, swift and great as a giant for I will not let his praises be sung from any other source than my own Scriptures— so mighty in strength that from one end to the other of the world he embraces all things in his heat, and there is nothing hid from the feeling thereof, but it fills both every eye with light, and every embodied creature with heat; warming, yet not burning, by the gentleness of its temper, and the order of its movement, present to all, and equally embracing all.
XXX. Have you considered the importance of the fact that a heathen writer speaks of the sun as holding the same position among material objects as God does among objects of thought? For the one gives light to the eyes, as the Other does to the mind; and is the most beautiful of the objects of sight, as God is of those of thought. But who gave him motion at first? And what is it which ever moves him in his circuit, though in his nature stable and immovable, truly unwearied, and the giver and sustainer of life, and all the rest of the titles which the poets justly sing of him, and never resting in his course or his benefits? How comes he to be the creator of day when above the earth, and of night when below it? Or whatever may be the right expression when one contemplates the sun? What are the mutual aggressions and concessions of day and night, and their regular irregularities— to use a somewhat strange expression? How comes he to be the maker and divider of the seasons, that come and depart in regular order, and as in a dance interweave with each other, or stand apart by a law of love on the one hand, and of order on the other, and mingle little by little, and steal on their neighbour, just as nights and days do, so as not to give us pain by their suddenness. This will be enough about the sun.
Do you know the nature and phenomena of the Moon, and the measures and courses of light, and how it is that the sun bears rule over the day, and the moon presides over the night; and while She gives confidence to wild beasts, He stirs Man up to work, raising or lowering himself as may be most serviceable? Know you the bond of Pleiades, or the fence of Orion as He who counts the number of the stars and calls them all by their names? Know you the differences of the glory of each, and the order of their movement, that I should trust you, when by them you weave the web of human concerns, and arm the creature against the Creator?
XXXI. What say you? Shall we pause here, after discussing nothing further than matter and visible things, or, since the Word knows the Tabernacle of Moses to be a figure of the whole creation— I mean the entire system of things visible and invisible— shall we pass the first veil, and stepping beyond the realm of sense, shall we look into the Holy Place, the Intellectual and Celestial creation? But not even this can we see in an incorporeal way, though it is incorporeal, since it is called— or is— Fire and Spirit. For He is said to make His Angels spirits, and His Ministers a flame of fire...though perhaps this “making” means preserving by that Word by which they came into existence. The Angel then is called spirit and fire; Spirit, as being a creature of the intellectual sphere; Fire, as being of a purifying nature; for I know that the same names belong to the First Nature. But, relatively to us at least, we must reckon the Angelic Nature incorporeal, or at any rate as nearly so as possible. Do you see how we get dizzy over this subject, and cannot advance to any point, unless it be as far as this, that we know there are Angels and Archangels, Thrones, Dominions, Princedoms, Powers, Splendours, Ascents, Intelligent Powers or Intelligencies, pure natures and unalloyed, immovable to evil, or scarcely movable; ever circling in chorus round the First Cause (or how should we sing their praises?) illuminated thence with the purest Illumination, or one in one degree and one in another, proportionally to their nature and rank...so conformed to beauty and moulded that they become secondary Lights, and can enlighten others by the overflowings and largesses of the First Light? Ministrants of God's Will, strong with both inborn and imparted strength, traversing all space, readily present to all at any place through their zeal for ministry and the agility of their nature...different individuals of them embracing different parts of the world, or appointed over different districts of the Universe, as He knows who ordered and distributed it all. Combining all things in one, solely with a view to the consent of the Creator of all things; Hymners of the Majesty of the Godhead, eternally contemplating the Eternal Glory, not that God may thereby gain an increase of glory, for nothing can be added to that which is full— to Him, who supplies good to all outside Himself but that there may never be a cessation of blessings to these first natures after God. If we have told these things as they deserve, it is by the grace of the Trinity, and of the one Godhead in Three Persons; but if less perfectly than we have desired, yet even so our discourse has gained its purpose. For this is what we were labouring to show, that even the secondary natures surpass the power of our intellect; much more then the First and (for I fear to say merely That which is above all), the only Nature.
