4. If, then, it was external to God, something else surely existed besides God, conceived, in respect of eternity, together with Him Who exists ungenerately; so that the argument supposes two eternal and unbegotten existences, having their being concurrently with each other—that of Him Who operates as an artificer, and that of the thing which admits this skilled operation; and if any one under pressure of this argument should assume a material substratum for the Creator of all things, what a support will the Manichæan find for his special doctrine, who opposes by virtue of ungenerateness a material existence to a Good Being. Yet we do believe that all things are of God, as we hear the Scripture say so; and as to the question how they were in God, a question beyond our reason, we do not seek to pry into it, believing that all things are within the capacity of God’s power—both to give existence to what is not, and to implant qualities at His pleasure in what is.
