Looking at what the Bible says (all ESV):
Exo 20:1 And God spoke all these words, saying,
Exo 20:2 "
I am the LORD your God, who brought you out of the land of Egypt, out of the house of slavery.
Exo 20:3 "
You shall have no other gods before me.
Exo 20:4 "You shall not make for yourself a carved image, or any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth.
Exo 20:5 You shall not bow down to them or serve them, for I the LORD your God am a jealous God, visiting the iniquity of the fathers on the children to the third and the fourth generation of those who hate me,
Exo 20:6 but showing steadfast love to thousands of those who love me and keep my commandments.
Deu 6:4 "Hear, O Israel: The LORD our God, the LORD is one.
Isa 43:10-11,
10 "You are my witnesses," declares the LORD, "and my servant whom I have chosen, that you may know and believe me and understand that I am he.
Before me no god was formed, nor shall there be any after me. 11 I, I am the LORD, and besides me there is no savior.
Isa 44:6-8, 6 Thus says the LORD, the King of Israel and his Redeemer, the LORD of hosts: "
I am the first and I am the last; besides me there is no god. 7 Who is like me? Let him proclaim it. Let him declare and set it before me, since I appointed an ancient people. Let them declare what is to come, and what will happen. 8 Fear not, nor be afraid; have I not told you from of old and declared it? And you are my witnesses!
Is there a God besides me? There is no Rock; I know not any."
Isa 45:18 For thus says the LORD, who created the heavens (he is God!), who formed the earth and made it (he established it; he did not create it empty, he formed it to be inhabited!): "
I am the LORD, and there is no other."
Isa 45:21 Declare and present your case; let them take counsel together! Who told this long ago? Who declared it of old? Was it not I, the LORD?
And there is no other god besides me, a righteous God and a Savior; there is none besides me.
Isaiah 46:9 remember the former things of old;
for I am God, and there is no other; I am God, and there is none like me,
These passages all show that
if, as you claim, Jesus is the God of Israel but not the one true God, then Jesus was a liar because clearly, as the God of Israel, he was claiming to be the one true God, the Creator. In fact, he makes it abundantly clear that there never has been nor ever will be another God.
There is absolutely no biblical support for saying that Jesus is the God of Israel but the Father is the true God. In fact, the Bible is very much against such a position and the passages I have given completely do away with your position. The God of Israel very much is the one true, creator God.
Not to mention what you have stated above goes against what you stated earlier:
MarkT said:
Jesus' function was basically to act as a temple for the living God. Jesus was fully a man. Can we say that? Yes. Otherwise how could we hope to be like him. I would not dispute Jesus was God's way of teaching us, in effect, God's way of communicating with man, but the basic truth of Christianity is Jesus was the Christ, the Son of the living God. To say Jesus was God or he was making himself God or equal to God dismisses what he said about himself with respect to the Father.
Was he fully a man and that's it? If I say that Jesus was God am I actually dismissing "what he said about himself with respect to the Father"? Your position is contradictory. You cannot rationally hold to a position which states that Jesus is only a man and that we cannot say he is God, and yet states that he is God, much less the God of Israel but not the one true God.
