22 I wish to give also a certain illustration of what I am saying, but I know that it is feeble; for of things visible what can be an exact illustration of the Divine Power? But nevertheless as feeble be it spoken by the feeble to the feeble. For just as any king, whose son was a king, if he wished to form a city, might suggest to his son, his partner in the kingdom, the form of the city, and he having received the pattern, brings the design to completion; so, when the Father wished to form all things, the Son created all things at the Father's bidding, that the act of bidding might secure to the Father His absolute authority, and yet the Son in turn might have authority over His own workmanship, and neither the Father be separated from the lordship over His own works, nor the Son rule over things created by others, but by Himself. For, as I have said, Angels did not create the world, but the Only-begotten Son, begotten, as I have said, before all ages, By Whom All Things Were Made, nothing having been excepted from His creation. And let this suffice to have been spoken by us so far, by the grace of Christ.
