John 16:12
I still have much to tell you, but you cannot yet bear to hear it. 13However, when the Spirit of truth comes, He will guide you into all truth.
I guess I see it as one of those things the disciples of Jesus could not bear to hear at that time. They did not have a fully worked out doctrine of the trinity but they were the ones who taught that Jesus is the Son of God and equal to His Father and they were the ones who called Him God and worshipped Him.
If He was a created angel He would not have allowed them to do that and would have said stop, just as the angel in Revelations said to John when he wanted to worship him.
ALL THINGS that have come into existence have come into existence through Him. John 1:3
Jesus was not created and did not come into existence at any time.
He is the ruler of creation. (see Rev 3:14, the first in priority over creation, see Col 1:15,16)
He has the name above all names.(Phil 2:9) He is Jehovah just like His dad and together with the Holy Spirit they are the One God.
