I'm not going to try and present to you Polytheism since I do not believe in many gods, but One God.
The concept of God being three in one is not something I have come to from reading creeds or church history or early church Fathers, but from reading scripture.
If the Word who WAS GOD in the beginning is not God who became flesh, then John 1:1 is incorrect.
Thank you for providing the quotes and in time I will deal with them all if God Wills.
Before we begin we need to clarify your position on the Godhead. Are you suggesting the Trinity is not Polytheism?
If so, I assume you see a single God who is in three parts?
Three gods but one god
And if so, you prefer to claim monotheism, yes?
By the way, I went through your verses to find the below terminology:
"But the Godhead of the Father, of the Son, and of the Holy Ghost, is all one: the Glory equal, the Majesty co-eternal. Such as the Father is, so is the Son, and such is the Holy Ghost.
“So likewise the Father is Almighty, the Son Almighty and the Holy Ghost Almighty. And yet there are not three Almighties, but one Almighty.
"So the Father is God, the Son is God, and the Holy Ghost is God. And yet there are not three Gods: but one God.
I searched each of these in the AV with zero hits.
- Son is God
- Son Almighty
- Holy Ghost Almighty
- three Gods
However, I search the Athanasian Creed and I found them!
