Jesus is not the word. The word is the good news of God the father. The word became flesh when Jesus Christ came into this world to preach the good news. Thats what it means. So no Jesus is not the word and jews did not use the word to ever refer to the messiah neither did john think oh let me be clever and call jesus the word.
It's all well and good to say that Jesus is not the Word, but I'm afraid if you want to consider it "theology" you will need the Bible to back you up.
John says, in John 1:1-18, that John the Baptist testified of the Word:
“This was he of whom I said, ‘He who comes after me ranks before me, because he was before me.’”
And later (Vs. 29) we read:
The next day he saw Jesus coming toward him, and said, “Behold, the Lamb of God, who takes away the sin of the world! 30 This is he of whom I said, ‘After me comes a man who ranks before me, because he was before me.’"
But beyond that, in John 1 we read that all things were created through Him (the Word, a.k.a. Jesus), and without Him not one thing was created that was created. In 1 Corinthians we read "yet for us there is one God, the Father, from whom are all things and for whom we exist, and one Lord,
Jesus Christ, through whom are all things and through whom we exist."
Furthermore, we have the testimony of the church fathers. Some of the oldest writings testify to this, including the works of St. Irenaeus, which I have alluded to in another forum. Here is an excerpt from his writings, "Against Heresies."
"For it was to this end that the Word of God was made man, and He who was the Son of God became the Son of man, that man, having been taken into the Word, and receiving the adoption, might become the son of God... But how could we be joined to incorruptibility and immortality, unless, first , incorruptibility and immortality had become that which we also are, so that the corruptible might be swallowed up by incorruptibility, and the mortal by immortality...
...For as he became man in order to undergo temptation, so also was He the Word that He might be glorified; the Word remaining quiescent, that He might be capable of being tempted, dishonoured, crucified, and of suffering death, but the human nature being swallowed up in it (the divine)... He therefore, the Son of God, our Lord, being the Word of the Father, and the Son of man..."
If you're not familiar with St. Irenaeus, he lived from 130 AD to 202 AD. Which means that next to the New Testament writers, his are the earliest written records of what the early church believed.
And in case you're wondering why somebody would be arguing against this heresy that early in church history, it's because the idea that the Word was not Jesus originated with the gnostic sects of the first and second centuries AD.
