The point is that whatever you consider to be the beginning, the Word already existed in relationship with God the Father.
Yes, but John 1:1 just proves that the Word existed in relationship with God SINCE THE BEGINNING OF THE UNIVERSE.
And I agree with that! (see my overview below)
But it does NOT prove that there were multiple separate individuals SINCE ETERNITY PAST.
That is the distinction of the DOCTRINE OF THE TRINITY.
Are you able to post an overview of what YOU believe? Here is mine...
For this creation, YHWH God (the only one who transcends all creations) determined to create a universe with a kingdom of redeemed humans (living souls) for his glory where he would reign as a living soul himself. The Scriptures describe how God would accomplish his plan. In an instant, transcendent God (called God the Father) created the supernatural and space-time of this universe and also became immanent as a spirit (called the Spirit of God) and in the form of a living soul (called the Word of God) with a glorious body. God the Father then created all things within the universe by the power of the Spirit of God commanded by the Word of God. But whereas God created a human spirit and soul for each of us, God himself as the Word became the human spirit and soul of Jesus. At his conception, Jesus' glorious body was changed to a mortal body to be made like us so he could make reconciliation for our sins. At his resurrection, Jesus' mortal body was changed back to a glorious body and he will also give each of his elect a glorious body when he returns to reign in his kingdom forever.
