Non Biblical?
Consider yourself corrected.
Matthew 28
18 And Jesus came and said to them, “All authority in heaven and on earth has been given to me.
19 Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit,
20 teaching them to observe all that I have commanded you; and lo, I am with you always, to the close of the age.”

And just where is the word “Trinity” in these verses. And these verses are after the resurrection and indeed after Christ did inherit all that The Father had. The very fact that “All Authority” had been given to Him meant that prior to that or at least at some time He didn’t have that “All Authority” which pretty much said He wasn’t always God.
When I would travel for the company I worked for I would go in the name of my company owners. they weren’t all the same however.
Father, Son and Holy Spirit
Why don’t you believe the words of Jesus?
John Chapter 1...”In the beginning was the WORD(logos) and the WORD was with God and the WORD was God” Go down further in the chapter and you read “And the WORD was made flesh and dwelt amongst us...” If the WORD was God and the Word was made flesh, then Christ is God in flesh! Logical enough for you? Jesus is God’s thumbprint pressed into matter!
John 1: 9The true Light who gives light to every man was coming into the world. 10He was in the world, and though the world was made through Him, the world did not recognize Him.…
Hence we know that the world was “made thru him”...that is Jesus...the light that has come into the world.
I encourage you to read thru the ist Chapter of the gospel of John....it should answer your questions about who Jesus is!
