“Who being” (saith he) “the brightness of His glory.” See what Paul is doing. Having said, “Who being the brightness of His glory,” he added again, “He sat down on the right hand of the Majesty”: what names he hath used, nowhere finding a name for the Substance. For neither “the Majesty,” nor “the Glory” setteth forth the Name, which he wishes to say, but is not able to find a name. For this is what I said at the beginning, that oftentimes we think something, and are not able to express [it]: since not even the word God is a name of substance, nor is it at all possible to find a name of that Substance.
