Friend, proof that it is you who are deceived is the doctrine of the trinity is not in the Bible.
The last verse of Acts 18 says the Apostles used the Tanaka to prove Jesus was - not God incarnate - but the Messiah.
Given these basic facts, on what bass do you disregard Scripture, in general, and the words of those who walked with Jesus, in particular, to advance this 4th century man-made doctrine?
It is you who have been deceived.
Scribe: Tell me, Teacher. What is the most important thing that God commands in the law?
Jesus: 29 The most important commandment is this: “Hear, O Israel, the Eternal One is our God, and the Eternal One is the only God.
Mark 12:28-29
‘For us, there is one God, the Father.’
1 Corinthians 8:6
Powerful accusations from one who doesn't even know what the book was called. they used the Tanach (not tanaka) yes to prove Jesus was Messiah! Because of the rejection of Jesus by the religious leaders, they showed from Scripture that Jesus fulfilled the Scriptures!
See I do not disregard Scripture as you selectively do! I fully know Jesus is Messiah and divine as well. Scriptures clearly shgow he is divine or god like His Father is divine or God. They share the same essence. Seeing as you reject the deity of jesus , what do you say He was before He became man?
I use verses like this to show Jesus is equally god(divine) with His Father:
John 1:1
King James Version
1 In the beginning was the Word, and the Word was with God, and the Word was God.
John 5:17-18
King James Version
17 But Jesus answered them, My Father worketh hitherto, and I work.
18 Therefore the Jews sought the more to kill him, because he not only had broken the sabbath, but said also that God was his Father, making himself equal with God.
John 10:30
I and my Father are one.
Genesis 1:1
King James Version
1 In the beginning God created the heaven and the earth.
John 1
King James Version
1 In the beginning was the Word, and the Word was with God, and the Word was God.
2 The same was in the beginning with God.
3 All things were made by him; and without him was not any thing made that was made.
God made the heavens and earth and Jesus is that God who made heaven and earth.
1 Timothy 3:16
And without controversy great is the mystery of godliness: God was manifest in the flesh, justified in the Spirit, seen of angels, preached unto the Gentiles, believed on in the world, received up into glory.
Philippians 2:6-10
King James Version
6 Who, being in the form of God, thought it not robbery to be equal with God:
7 But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men:
8 And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross.
9 Wherefore God also hath highly exalted him, and given him a name which is above every name:
10 That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth;
I could on and on showing that it is the bible that forms my doctrine. why do you reject these Scriptures?
I accept all the roles Jesus had and now has and will have. Which is why I can say He is equal to God in nature, subservient to God in position in the God head and the same as God the Father. I also accept He is Messiah/Christ/Savior as the Scriptures also teach
I also accept He was fully man, physically rose from the dead, physically ascended into heaven with a glorified body as the firstfruits, will physically return, will rule for 1,000 years and then submit Himself back to His Father and my Father as the Scriptures declare!
The bible will never contradict itself. If it appears to do so- it is because the understanding of one like you is wrong.
