This is a reply to another poster on another thread, but it answers your question.
While I agree with you regarding the Trinity doctrine as portrayed in the creeds and many church manuals, I cannot agree with you regarding the Son. I have read 1 John numerous times. No where is there any hint that the relationship between Jesus and the Father is anything other than real. The Father/Son paradigm is not metaphorical. Nor did the Father become a Father at the incarnation. They two were two separate beings, persons, before creation, the Father creating all things through the agency of His Son.
KJV
Hebrews 1:1-3
1 God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets,
2 Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds;
3 Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high;
The Son is the express image of the Father, begotten with all the fullness of the Godhead. The Father is God, and the Son is God manifest.
Picture if you will two windows. Before creation. Before anything outside of God was created. God alone. No universe. No worlds. No angels. Just God. He fills the first window. That's all there is in that window. God and God alone. Then the Son is begotten. He isn't created, because scripture tells us the Son created everything. So He doesn't belong in the second window, He belongs in the first. He inherited all things from the Father. All that the Father is, the Son is.
“For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.”
John 3:16
Jesus told Nicodemus that God “gave” His Son. This is the everlasting gospel. If God did not possess a son then He would not have had a son to give. It must follow therefore that Christ was God’s “only begotten Son” before He came to earth.
That God gave His Son as a sacrifice for sin is the core-belief of Christianity. Without this belief, Christianity is meaningless. It is therefore a subject that not only demands our fullest attention but also needs great care when being presented. To get it wrong will pervert the gospel. A correct understanding of the atonement is totally dependent on a correct understanding of the relationship between God the Father and His Son.
Those who teach that Christ is not really the Son of God are perverting what it cost God in redeeming mankind from sin. They are also perverting, in the minds of those who believe what they say, the love that God has for humanity.
The apostle Paul wrote
“For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh:”
Romans 8:3
“He that spared not his own Son, but delivered him up for us all, how shall he not with him also freely give us all things?”
Romans 8:32
When expressing this great truth to his little flock, John the gospel writer put it this way
“Beloved, let us love one another: for love is of God; and every one that loveth is born of God, and knoweth God. He that loveth not knoweth not God; for God is love. In this was manifested the love of God toward us, because that God sent his only begotten Son into the world, that we might live through him. Herein is love, not that we loved God, but that he loved us, and sent his Son to be the propitiation for our sins. Beloved, if God so loved us, we ought also to love one another.”
1 John 4:7-11
It is only when we realize that God really did give His Son that we can say we truly understand the gospel. Any other understanding of it is a perversion. In order to make manifest God’s love in the way that we treat others we need to correctly understand what God has done through His Son. It is only when we see the ‘other person’ (whoever that may be) as someone purchased by the blood of God’s only begotten Son that we are able to treat that person as they should be treated. Christ died for everyone. He did not die only for those who will be saved. We must regard everyone as the purchase of God. There are no exceptions.
John also wrote
“Who is he that overcometh the world, but he that believeth that Jesus is the Son of God?…He that believeth on the Son of God hath the witness in himself: he that believeth not God hath made him a liar; because he believeth not the record that God gave of his Son. And this is the record, that God hath given to us eternal life, and this life is in his Son.”
1 John 5:5, 10-11
Begotten in the express image of God’s person
The Scriptures also tell us
“For it pleased the Father that in him [in Christ] should all fulness dwell; Colossians” 1:19
This is referring to the fullness of deity. As it says in
Colossians 2:9
“For in him [in Christ] dwelleth all the fulness of the Godhead bodily.”
The Scriptures tell us that it was God’s pleasure to have His fullness dwell in the Son. Christ therefore was God Himself (the fullness of deity) in the person of the Son (
John 1:1-3,
Hebrews 1:1-3). This was Christ’s inheritance as a son. As a son He received (inherited) all things from His father (God the Father). As we are told in the opening verses of the book of Hebrews
“God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets, Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds; Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high:”
Hebrews 1:1-3
Like I said above. If the Son inherited everything the Father is... The express image... Then the Son is God.
