It is not significant that the trinity (as a word) isn't in the OT, because it wasn't their (Israel's) concern.
Neither was it God's concern to inform them about such a monumental truth.
Hmmmm!!!!
Since we know that Jesus is the word...
You need to tell this to the prophets, Jesus and the apostles.
John referred to Isa 55:11.
Logos never denotes Jesus.
God the Father and the spirit of God...
Why not God the Spirit?
Deny all you want but take care Matt. 12:31- "Wherefore I say unto you, All manner of sin and blasphemy shall be forgiven unto men: but the blasphemy against the Holy Ghost shall not be forgiven unto men. [sup]32 [/sup]And whosoever speaketh a word against the Son of man, it shall be forgiven him: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come."
1. The Father is not mentioned.
2. Jesus is lesser than the Holy Ghost.
In my opinion, denying His existence, separate from God is coming close to blasphemy.
You based your opinion on man made story.
You need to get rid of it and consider hundreds of proof texts which make it clear that those who trample upon them and make themselves other "Gods" are blaspheming (and are accursed) the Father the only one true God.
Maybe you can supply some scripture that supports God is NOT tripartite?
You don't seem to know that God speaks about things that are.
Here are some of hundreds proof texts you trample upon in order of promoting the unbiblical theology (the two "Gods" of 325 were declared unbiblical in 357 but had to become politically correct with addition of the third "God" in 381):
