Scripture is neither pro-Trinity nor specifically anti-Trinity.
Scripture is pro-one God of Israel and anti-idolatry.
What does Jesus do? He keeps us within the sphere of the one God of Israel, his God.
What does trinitarianism do? It attempts to position the Trinity - not the one God of Jesus - as the one God of Israel.
Scripture - OT and NT - comes to us from the Jews (unitarians); not from the trinitarians.
“We are therefore come to (the gist of) our position; for at this point we were aiming, and for this we were preparing in the preamble of our address (which we have just completed), - so that we may now join issue on the contention to which our adversaries challenge us. They put forward the Scriptures, and by this insolence of theirs they at once influence some. In the encounter itself, however, they weary the strong, they catch the weak and dismiss waverers with a doubt. Accordingly, we oppose to them this step above, of all others, of not admitting them to any discussion of the Scriptures.
If in these these lie their resources, before they can use them, it ought to be clearly seen to whom belongs the possession of the Scriptures, that none may be admitted to the use thereof who has no title at all to the privilege.”
(Tertullian,
The Prescription Against Heretics, Chapter 15)
Tertullian (Roberts-Donaldson)
We who will not acknowledge any other God than the one God whom Jesus insists is his God and our God - the one God of Israel - are called heretics by those who will. They do so without having the title to the privilege.
P.S.
I’m not suggesting that we shouldn’t discuss scripture with the trinitarians. I believe that we should. What I’m saying is that we aren’t what they aggressively insist we are and, keeping that in mind, our conversation with them should be markedly different in both tone and content.
