Only by confusion can Trinitarians prevail.

 The ONLY Way that Trinitarians can appear to prevail in debate is by confusion. That is why it is so important to clarify definitions from the begining. Who/what is the most high God? Is this most high God triune? Is this trinity composed of three distinct Gods.

Is any of these three distinct persons/Gods the most high God?

This is especially the case when they attempt to use/misuse disputed scriptures like 

Romans ch.9:5NCB"to them belong the patriarchs, and from them, according to the flesh, comes the Messiah,[b] who is over all, God blessed for ever.[c] Amen."

Obviously Paul is glorifying the one and only most high God for favouring Israel spiritually. The greatest of these favours is that of having the saviour of mankind as a descendent of their patriarchs and prophets. Some Trinitarians in a desperate attempt to extract proof for their extra biblical claims of a triune most high God, claim that Paul is making the Messiah who sprang from Israel according to the flesh numerically identical to the most high God.

The problem of course is that if the very unipersonal Messiah is made to be the MOST HIGH GOD then the obvious result is a falsifying of the Nicene creed. Which plainly declares that the constituents of the trinity are merely distinct persons but not distinct Gods or Lords and certainly not that most distinct most high God and most high Lord who/which is tri-personal.

Romans ch.9:5CJB"the Patriarchs are theirs; and from them, as far as his physical descent is concerned, came the Messiah, who is over all. Praised be Adonai for ever! Amen."

Romans ch.9:5CEV"They have those famous ancestors, who were also the ancestors of the Christ.[a] I pray that God, who rules over all, will be praised forever![b] Amen."

Romans ch.9:5GNT"they are descended from the famous Hebrew ancestors; and Christ, as a human being, belongs to their race. May God, who rules over all, be praised forever![b] Amen."

Romans ch.9:5TLB"Great men of God were your fathers, and Christ himself was one of you, a Jew so far as his human nature is concerned, he who now rules over all things. Praise God forever!"

Romans ch.9:5NAB(RE)"They are Israelites; theirs the adoption, the glory, the covenants, the giving of the law, the worship, and the promises; 5 theirs the patriarchs, and from them, according to the flesh, is the Messiah. God who is over all[c] be blessed forever. Amen."

Romans ch.9:5NLV"The early preachers came from this family. Christ Himself was born of flesh from this family and He is over all things. May God be honored and thanked forever. Let it be so."

Romans ch.9:5RSV"to them belong the patriarchs, and of their race, according to the flesh, is the Christ. God who is over all be blessed for ever.[a] Amen."

Romans ch.9:5Goodspeed"and the patriarchs, and from them physically Christ came—God who is over all be blessed forever! Amen. "
