The NT does state that Gods only like to like "begotten" Son shares His Fathers nature and that Son is called God.Bible does not teach that ,the churches teach that.
which did not happen till 200-300 years after jesus died
Col 1:19 Col 1:15
Hebrews 1:3
John 1:1
Just as it teaches the only "unbegotten" God is the Father and He is the God and "Father" of ALL including His Son who we now call Jesus and Lord.
A distinction was made that is not captured in orthodox trinity statements
1 Corinthians 8:6
Ephesians 3:14-15
1 Corth 1:3
I disagree that Jesus is the only unbegotten, begotten Son of the Father.
I disagree in a 3rd distinct person known as God the Spirit. Though the "Fathers" Spirit would have His nature it's the person of the Father. When the Father pours out His Spirit in Jesus's name then that Spirit is in the persona of the Son living in those in the faith and in that context is the person of the Son and in that manner both the Father and Son make their home with those in the faith Paul spoke of.
I hold to this statement from the beginning.
yet for us there is but one God, the Father, from whom all things came and for whom we live; and there is but one Lord, Jesus Christ, through whom all things came and through whom we live.
And in regard to Jesus the Lord I hold to this statement in regard to nature of the Son.
The Son is the radiance of God’s glory and the exact representation of his being, sustaining all things by his powerful word. After he had provided purification for sins, he sat down at the right hand of the Majesty in heaven.
So I agree in part.
Begotten of the Father before all things but not made.
Its God from true God for me, not true God from true God. Jesus is the first begotten of the Father. He is God the begotten. The Father is the only unbegotten God and the Father and God of all.
One God the Father; One Lord Jesus Christ who shares "His" Fathers nature they are ONE.
Its dishonest to call those who believe in true God from true God "false" Christians.
This is the test stated. (I pass this test)
Examine yourselves to see whether you are in the faith; test yourselves. Do you not realize that Christ Jesus is in you—unless, of course, you fail the test?
