You do know that the Trinity is of pagan origin, correct?
Why are you trying to force paganism onto a theology of ethical monotheism? “Mono” in monotheism is about one God who isn’t divisible in any way, shape, or form.
God, through the Jews, says over and over he isn’t physical or a man, isn’t divisible, and beyond space and time, yet mankind keeps saying the opposite. Over 3,300 years and you still can’t let go of those pagan ideas.
Hosea 11:9
I will not execute the kindling of My anger, I will not return to destroy Ephraim, for I am God and not a man. In your midst is the Holy One, and I will not enter a city.
Numbers 23:19
God is not a man that He should lie, nor is He a mortal that He should relent. Would He say and not do, speak and not fulfill?
1st Samuel 15:29
And also, the Strength of Israel will neither lie nor repent, for He is not a man to repent.
Job 9:32
For He is not man like me, that I should answer Him, ‘Let us come together in debate.’
Isaiah 44:6
So said the Lord, the King of Israel and his Redeemer the Lord of Hosts, “I am first and I am last, and besides Me there is no God.
Isaiah 44:8
Do not tremble, do not be afraid. Did I not proclaim this and foretell it long ago? You are my witnesses. Is there any God besides me? No, there is no other Rock; I know not one.”
Even the Christian’s New Testament gets this one verse correct about the truth that God is not physical nor a man.
“God is spirit, and his worshipers must worship in the Spirit and in truth.”
John 4:24
