Upon the Sovereign Sun (362), Context: To explain, however, everything relating to the nature of this deity, is beyond the power of man, even though the god himself should grant him the ability to understand it: in a case where it seems, to me at least, impossible even mentally to conceive all its extent. And now that we have discussed so much, we must put as it were a seal upon this subject; and to stay a while and pass on to other points no less requiring examination. What then is this seal; and what comprises everything, as it were in a summary of the conception concerning the nature of the god? May He Himself inspire our understanding when we attempt briefly to explain the source out of which he proceeded; and what he is himself; and with what effects he fills the visible world. It must therefore be laid down that the sovereign Sun proceeded from the One God, — One out of the one Intelligible world; he is stationed in the middle of the Intelligible Powers, according to the strictest sense of "middle position;" bringing the last with the first into a union both harmonious and loving, and which fastens together the things that were divided: containing within himself the means of perfecting, of cementing together, of generative life, and of the uniform existence, and to the world of Sense, the author of all kinds of good; not merely adorning and cheering it with the radiance wherewith he himself illumines the same, but also by making subordinate to himself the existence of the Solar Angels; and containing within himself the unbegotten Cause of things begotten; and moreover, prior to this, the unfading, unchanging source of things eternal.
All, therefore, that was fitting to be said touching the nature of this deity (although very much has been passed over in silence) has now been stated at some length.
