19 Reverence for the One Unbegotten Creator distressed me, lest in your sweeping assertion that all things were made by the Word you had included Him. You have banished my fears by your Without Him was nothing made. Yet this same Without Him was nothing made brings trouble and distraction. There was, then, something made by that Other; not made, it is true, without Him. If the Other did make anything, even though the Word were present at the making, then it is untrue that through Him all things were made. It is one thing to be the Creator's Companion, quite another to be the Creator's Self. I could find answers of my own to the previous objections; in this case, Fisherman, I can only turn at once to your words, All things were made through Him. And now I understand, for the Apostle has enlightened me:— Things visible and things invisible, whether thrones or dominions or principalities or powers, all are through Him and in Him.
