23 But let us now recur to our profession of the Faith, and so for the present finish our discourse. Christ made all things, whether thou speak of Angels, or Archangels, of Dominions, or Thrones. Not that the Father wanted strength to create the works Himself, but because He willed that the Son should reign over His own workmanship, God Himself giving Him the design of the things to be made. For honouring His own Father the Only-begotten says, The Son can do nothing of Himself, but what He sees the Father do; for what things soever He does, these also does the Son likewise. And again, My Father works hitherto, and I work, there being no opposition in those who work. For all Mine are Yours, and Yours are Mine, says the Lord in the Gospels. And this we may certainly know from the Old and New Testaments.
For He who said, Let us make man in our image and after our likeness, was certainly speaking to some one present. But clearest of all are the Psalmist's words, He spoke and they were made; He commanded, and they were created, as if the Father commanded and spoke, and the Son made all things at the Father's bidding. And this Job said mystically, Which alone spread out the heaven, and walks upon the sea as on firm ground; signifying to those who understand that He who when present here walked upon the sea is also He who aforetime made the heavens.
And again the Lord says, Or did Thou take earth, and fashion clay into a living being? Then afterwards, Are the gates of death opened to You through fear, and did the door-keepers of hell shudder at sight of You? Thus signifying that He who through loving-kindness descended into hell, also in the beginning made man out of clay.
