Chizuk Emunah (Pt 2) Under the Microscope: Chapter 55

John 17:3, Jesus says, "And this is life eternal, that they might know Thee, the only true God, and Jesus Christ, whom thou hast sent." In this verse, Jesus acknowledged himself to be merely a messenger, and not an integral part of the Deity. The awe and worship due to the Almighty is also, in 1 Timothy 1:17, declared to belong to God alone; for we find there, "Now unto the king eternal, immortal, invisible, the only wise God, be honour and glory for ever and ever, amen." If Jesus does not share the glory of God, he must be dependent on the will of his Creator, like every other creature. 

 Troki gives an allusion to Isaiah 42:

“I am the Lord, I have called You in righteousness,
I will also hold You by the hand and watch over You,
And I will appoint You as a covenant to the people,
As a light to the nations,
To open blind eyes,
To bring out prisoners from the dungeon
And those who dwell in darkness from the prison. “I am the Lord, that is My name;
I will not give My glory to another,
Nor My praise to graven images. “Behold, the former things have come to pass,
Now I declare new things;
Before they spring forth I proclaim them to you.”

Again, Troki reads John while ignoring the first 18 verses, which give the background needed to understand this book. A key verse is 14

And the Word became flesh, and dwelt among us, and we saw His glory, glory as of the only begotten from the Father, full of grace and truth.

Let's look at John 12:

These things Jesus spoke, and He went away and hid Himself from them. But though He had performed so many [n]signs before them, yet they were not believing in Him. This was to fulfill the word of Isaiah the prophet which he spoke: “Lord, who has believed our report? And to whom has the arm of the Lord been revealed?” For this reason they could not believe, for Isaiah said again, “He has blinded their eyes and He hardened their heart, so that they would not see with their eyes and perceive with their heart, and be converted and I heal them.” These things Isaiah said because he saw His glory, and he spoke of Him. Nevertheless many even of the rulers believed in Him, but because of the Pharisees they were not confessing Him, for fear that they would be put out of the synagogue; for they loved the approval of men rather than the approval of God.

 John is quoting Isaiah 6, which speaks of God's glory and says that Isaiah saw the glory of Jesus. This can only make sense if Jesus is God.

Regarding John 17, what exactly did we expect Jesus to say? Did we expect him to say that you, Father, are just one of many gods? If the Jehovah's Witnesses were right that this verse teaches that only the Father is God, then they would have to reject Jesus as a false God, because even the New World Translation translates John 1:1 as saying that Jesus was a god.

Again, Troki's answer is a straw man attack on the idea of Trinitarian monotheism. This is to say that there is one God, but that God is not one person. I think of this as one mind with multiple centers of self-consciousness. Since there is one God, any of the three persons could say to another "you are the only true God" and the statement would be true.
