You are wrong.
Borrowing this from another poster:
One being need not equate to one person. A cat or a dog is one being and NO persons. A bird or a fish is one being and NO persons. A human is one being and ONE person. God is one being and THREE persons.
"Being" refers to what we are. "Person" refers to who we are. God, the Bible states, is Father, Son, Holy Spirit. WHO he is is three persons. WHAT he is is one God.
Jesus tells his apostles to baptize "in the name [notice, singular, not plural] of the Father and of the Son and of the Holy Spirit" (Matt. 28:19). This is a proof-text: three distinct Persons united in the one divine name. In 2 Corinthians 13:14, Paul writes, "The grace of the Lord Jesus Christ and the love of God and the fellowship of the Holy Spirit be with you all." We see this same unity of divine Persons in 1 Corinthians 12:4–11, Ephesians 4:4–6, and 1 Peter 1:2–3.
The Bible clearly teaches that Jesus is God (cf. John 8:58, 10:38, 14:10; Col. 2:9). It also clearly teaches that the Holy Spirit is God (cf. Acts 5:3–4, 28:25–28; 1 Cor. 2:10–13). Everyone agrees the Father is God. Yet there is only one God (Mark 12:29, 1 Cor. 8:4–6, Jas. 2:19). How can we hold all four truths except to say all three are One God?
And yes, Jesus DID say he was God. In John 8:58, when quizzed about how he has special knowledge of Abraham, Jesus replies, "Truly, truly, I say to you, before Abraham was, I Am"—invoking and applying to himself the personal name of God—"I Am" (Ex. 3:14). His audience understood exactly what he was claiming about himself. "So they took up stones to throw at him; but Jesus hid himself, and went out of the temple" (John 8:59).
Also significant are passages that apply the title "the First and the Last" to Jesus. This is one of the Old Testament titles of Yahweh: "Thus says Yahweh, the King of Israel and his Redeemer, Yahweh of armies: ‘I am the First and I am the Last; besides me there is no god’" (Is. 44:6; cf. 41:4, 48:12).
Scripture is God's word, not man's word. God's logos, based on God's complete knowledge, wisdom and understanding. God, being perfect, His Word, His logos, is likewise perfect.
I, for one, believe that God tells us everything that pertains to life and godliness in scripture. I Peter 1:3-4
Therefore, everything we need to know about living a godly life is found in scripture precisely and perfectly communicated.
That includes answers to questions like
Who is God? Who is not God?
Who is the son of God? Are there differences between God and His son?
If you actually rely on scripture for answers,
Can you show me a scripture that refers to God as a "being"?
Can you show me a scripture that refers to "God is one being and THREE persons." or God being three persons?
For the most part, the word person(s) in the KJV refers to people
Below are several examples:
Deuteronomy 10:17
For the Lord your God is God of gods, and Lord of lords, a great God, a mighty, and a terrible, which regardeth not
persons, nor taketh reward:
2 Chronicles 19:7
Wherefore now let the fear of the Lord be upon you; take heed and do it: for there is no iniquity with the Lord our God, nor respect of
persons, nor taking of gifts.
Luke 15:7
I say unto you, that likewise joy shall be in heaven over one sinner that repenteth, more than over ninety and nine just
persons, which need no repentance.
Below we have a reference to Chist being a person, but since Christ is referred to as the man in I Timothy 2:5, again person refers to a human.
2 Corinthians 2:10
To whom ye forgive any thing, I forgive also: for if I forgave any thing, to whom I forgave it, for your sakes forgave I it in the
person of Christ;
Below we have a reference to God as a person, however, it is singular, ie, one person, not three. thus your conclusions are clearly guess work at best.
Hebrews 1:3
Who being the brightness of his glory, and the express image of his
person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high:
Matthew 28:19 has been shown to be a forgery in other posts, I believe Cherubim supplied some info on that.
As for your list of other verses, when you take them in the context of scripture, they actually show that Jesus in not God, but the son of God.
You stated:
"And yes, Jesus DID say he was God. In John 8:58, when quizzed about how he has special knowledge of Abraham, Jesus replies, "Truly, truly, I say to you, before Abraham was, I Am"—invoking and applying to himself the personal name of God—"I Am" (Ex. 3:14). His audience understood exactly what he was claiming about himself. "So they took up stones to throw at him; but Jesus hid himself, and went out of the temple" (John 8:59)."
I find that an amusing guess at the meaning of "Before Abraham was, I am"
Can you find any other quote of Jesus Christ that defies grammar like your interpretation of that phrase?
When Jesus uses the words, "I am" in other passages, he states what "I am" is.
He affirms that he is the son of God
Luke 22:70
Then said they all, Art thou then the Son of God? And he said unto them, Ye say that
I am.
Jesus tells us that he is the bread of life
John 6:35
And Jesus said unto them,
I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst.
John 6:48
I am that bread of life.
Jesus affirms that he is the light of the world.
John 8:12
Then spake Jesus again unto them, saying,
I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.
John 9:5
As long as
I am in the world,
I am the light of the world.
and
John 10:7
Then said Jesus unto them again, Verily, verily, I say unto you,
I am the door of the sheep.
John 10:11
I am the good shepherd: the good shepherd giveth his life for the sheep.
Jesus calls himself, not God, but the son of God
John 10:36
Say ye of him, whom the Father hath sanctified, and sent into the world, Thou blasphemest; because I said,
I am the Son of God?
John 11:25
Jesus said unto her,
I am the resurrection, and the life: he that believeth in me, though he were dead, yet shall he live:
So, why the grammatical inconsistency in John 8:58
If he was actually declaring himself to be what you call "I am" he would have said, "Before Abraham was, I am I am" which he did not do.
for that matter, what does "Before Abraham was" and "I am " or "I am I am" have to do with each other, why not just skip over Abraham and say "I am I am"?
The foolishness of the claim that Jesus is claiming to be God is evident for those who have eyes to see and ears to hear
