Had He been of inferior substance, He would not have put this. But now that thou mayest not deem that the Father is included, to make up the number (of two), observe that His power hath nothing different (from the Father’s). A man bears witness when he is trustworthy of himself, not when he himself needs testimony, and that too in a matter pertaining to another; but in a matter of his own, where he needs the witness of another, he is not trustworthy. But in this case it is all contrary. For He though bearing witness in a matter of His own, and saying that witness is borne to Him by another, asserteth that He is trustworthy, in every way manifesting His independence. For why, when He had said, “I am not alone, but I and the Father that sent Me,” and, “The testimony of two men is true,” did He not hold His peace, instead of adding, “I am One that bear witness of Myself”? It was evidently to show His independence. And He placeth Himself first; “I am One that bear witness of Myself.” Here He showeth His equality of honor, and that they were profited nothing by saying that they knew God the Father, while they knew not Him. And He saith that the cause of this (ignorance) was that they were not willing to know Him. Therefore He telleth them that it was not possible to know the Father without knowing Him, that even so He might draw them to the knowledge of Him. For since leaving Him they even sought to get the knowledge of the Father, He saith, “Ye cannot know the Father without Me.” ( Ver. 19.) So that they who blaspheme the Son, blaspheme not the Son only, but Him that begat Him also.
