9 Who can fail to observe that these statements are full of fraud and fallacy? Cleverly as issues have been confused and texts combined, malice and folly is the character indelibly imprinted upon this laborious effort of cunning and clumsiness. For instance, among their points of faith they have included this, that they confess the Father only to be unborn; as though any one on our side could suppose that He, Who begot Him through Whom are all things, derived His being from any external source.
The very fact that He bears the name of Father reveals Him as the cause of His Son's existence. That name of Father gives no hint that He who bears it is Himself descended from another, while it tells us plainly from Whom it is that the Son is begotten. Let us therefore leave to the Father His own special and incommunicable property, confessing that in Him reside the eternal powers of an omnipotence without beginning. None, I am sure, can doubt that the reason why, in their confession of God the Father, certain attributes are dwelt upon as peculiarly and inalienably His own, is that He may be left in isolated possession of them.
For when they say that He alone is true, alone is righteous, alone is wise, alone is invisible, alone is good, alone is mighty, alone is immortal, they are raising up this word alone as a barrier to cut off the Son from His share in these attributes. He Who is alone, they say, has no partner in His properties. But if we suppose that these attributes reside in the Father only, and not in the Son also, then we must believe that God the Son has neither truth nor wisdom; that He is a bodily being compact of visible and material elements, ill-disposed and feeble and void of immortality; for we exclude Him from all these attributes of which we make the Father the solitary Possessor.
