9 Thus we have all these different assurances of the Divinity of our Lord Jesus Christ:— His name, His birth, His nature, His power, His own assertion. As to the name, I conceive that no doubt is possible. It is written, In the beginning was the Word, and the Word was with God, and the Word was God. What reason can there be for suspecting that He is not what His name indicates? And does not this name clearly describe His nature? If a statement be contradicted, it must be for some reason. What reason, I demand, is there in this instance for denying that He is God? The name is given Him, plainly and distinctly, and unqualified by any incongruous addition which might raise a doubt. The Word, we read, which was made flesh, was none other than God. Here is no loophole for any such conjecture as that He has received this name as a favour or taken it upon Himself, so possessing a titular Godhead which is not His by nature.
