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
The NT very clearly speaks of God as Father, Son, and Holy Spirit. They can't be three "gods" because there aren't "gods," there is only one (see Isaiah 43-45). They can't be one God and two lesser beings (cf Jehovah's Witnesses), both because they are spoken of as being equals, and also because Hebrews has the Father commanding his angels to worship the Son.
The only way it makes sense is to understand that the One God is one Divine essence but also exists eternally as a perfect society of Divine Persons.
If, as the Christian scripture teaches, "God is love," and (as reason teaches) God is utterly perfect in Himself without reference to His creation, then God is necessarily a communion of Persons, since love always requires both a "lover" and a "beloved".
Here's a related concept as described in the Tree of Souls:
Some say that the soul of the Messiah has been exiled to a place of desert and desolation where no one walks. A storm wind rose up and created such confusion that the Messiah lost all the signs that were given to him, with which he was to identify himself before the people of Israel. As a result, it became impossible to recognize him, for he had no way of revealing himself.Furthermore, some of the lost signs and marvels of the Messiah were found by false prophets who began to appear, calling themselves by the name Messiah. But once their lies and wantonness were exposed, their false teachings were revealed for all the world to see.
Others say that the soul of the Messiah has been chained and is being held captive by the forces of evil. Not until the chains of the Messiah are broken will the captive soul of the Messiah be set free.
In any case, the smart money's on those who recognized the problem and got straight to work on it.
