First, then, I think we must consider that name which is so commonly used in Holy Scripture, that is, God (Θεός). For although there are many names by which the Divine Nature is called, such as Goodness, Essence, Truth, and others of this kind, yet that is the name which most frequently occurs in Scripture. (...)
Of this name [then] an etymology has been taken over from the Greeks: for either it is derived from the verb θεωρῶ, that is, "I see"; or from the verb θέω, that is, "I run"; or-which is more likely [since] the meaning of both is [one and] the same-it is correctly held to be derived from both. For when it is derived from the verb θεωρῶ, Θεὸς is interpreted to mean "He Who sees," for He sees in Himself all things that are [while] He looks upon nothing that is outside Himself because outside Him there is nothing. But when Θεὸς is derived from the verb θέω it is correctly interpreted "He Who runs," for He runs throughout all things and never stays but by His running fills out all things, as it is written: "His Word runneth swiftly."
[And yet He is not moved at all. For of God] it is most truly said that He is motion at rest and rest in motion. For He is at rest unchangingly in Himself, never departing from the stability of His Nature; yet He sets Himself in motion through all things in order that those things which essentially subsist by Him may be. For by His motion all things are made. And thus there is one and the same meaning in the two interpretations of the same name, which is God. For in God to run through all things is not something other than to see all things, but as by His seeing so too by His running all things are made. (...)
