“I feel how difficult it is for the human mind even to form a conception of that Sun who is not visible to the sense, if our notion of Him is to be derived from the Sun that is visible; but to express the same in language, however inadequately, is, perhaps, beyond the capability of man!”

Upon the Sovereign Sun (362)
Context: That divine and all-beauteous World, which from the highest vault of Heaven down to the lowest Earth is held together by the immutable providence of God, and which has existed from all eternity, without creation, and shall be eternal for all time to come, and which is not regulated by anything, except approximately by the Fifth Body (of which the principle is the solar light) placed, as it were, on the second step below the world of intelligence; and finally by the means of the "Sovereign of all things, around whom all things stand." This Being, whether properly to be called "That which is above comprehension," or the "Type of things existing," or "The One," (inasmuch as Unity appears to be the most ancient of all things), or "The Good," as Plato regularly designates Him, This, then, is the Single Principle of all things, and which serves to the universe as a model of indescribable beauty, perfection, unity, and power. And after the pattern of the primary substance that dwells within the Principle, He hath sent forth out of Himself, and like in all things unto Himself, the Sun, a mighty god, made up of equal parts of intelligible and creative causes. And this is the sense of the divine Plato, where he writes, "You may say (replied I) that I mean the offspring of the Good, whom the Good has produced, similar to itself; in order that, what the Good is in the region of intelligence, and as regards things only appreciable by the mind, its offspring should be the same in the region that is visible, and in the things that are appreciable by the sight." For this reason I believe that the light of the Sun bears the same relation to things visible as Truth does to things intelligible. But this Whole, inasmuch as it emanates from the Model and "Idea" of the primal and supreme Good, and exists from all eternity around his immutable being, has received sovereignty also over the gods appreciable by the intellect alone, and communicates to them the same good things, (because they belong to the world of intelligence), as are poured down from the Supreme Good upon the other objects of Intelligence. For to these latter, the Supreme Good is the source, as I believe, of beauty, perfection, existence, and union; holding them together and illuminating them by its own virtue which is the "Idea" of the Good.

Upon the Sovereign Sun (362)
Context: The one absolutely, the Intelligible, the ever Preexisting, comprehending all the universe together within the One — nay, more, is not the whole world One living thing — all and everywhere full of life and soul, perfect and made up out of parts likewise perfect? Now of this double unity the most perfect part (I mean of the Unity in the Intelligible World that comprehends all things in One, and of the Unity encompassing the Sensible World, that brings together all things into a single and perfect nature) is the perfection of the sovereign Sun, which is central and single, and placed in the middle of the intermediate Powers. <!-- But coming after this, there exists a certain connection in the Intelligible World with the Power that orders and arranges all things in one. Does not the essence of the Fifth Body, which is turned, as it were by a lathe, in a circle, move around the heavens, and is that which holds together all the parts, and binds them to one another, uniting what is naturally united amongst them and also those parts that mutually affect each other. These two essences, which are the causes of mutual attraction and of union (whereof the one manifests itself in the Intelligible, the other in the Sensible creation) does the Sun thus concentrate into one. Of the former he imitates this power of embracing and containing all things in the Intelligible creation, inasmuch as he proceeds from that source; whilst he governs the latter, that which is perceptible in the world of Sense. Perhaps, therefore, the self-existent principle, which existed first in the Intelligible creation, and lastly in the Visible bodies of the heavens, is owner of the intermediate, self-created essence of the sovereign Sun, from which primal creative essence there descends upon the visible world the radiance which illuminates the universe.

Christ's Object Lessons (1900)
Context: In Christ's parable teaching the same principle is seen as in His own mission to the world. That we might become acquainted with His divine character and life, Christ took our nature and dwelt among us. Divinity was revealed in humanity; the invisible glory in the visible human form. Men could learn of the unknown through the known; heavenly things were revealed through the earthly; God was made manifest in the likeness of men. So it was in Christ's teaching: the unknown was illustrated by the known; divine truths by earthly things with which the people were most familiar.
