Why is it Trinitarians try to prove both Jesus and Paul are liars?
Exodus 3:14 should be translated I WILL BE who/that/what I WILL BE. The I Ams of Christ are I am the light, bread, door, only way to the Father, and etc.
Isaiah 7:14 is a stretch since Mary named her son Yehoshua (God is salvation) not Immanuel. Jesus is God with us since he is the image of the invisible God (Colossians 1:15), the exact representation of God's nature (Hebrew 1:3), and was given all authority in heaven and on earth (Matthew 28:18).
Isaiah 9:6 is a list of titles, which Trinitarians mistranslate. In no Scripture is Jesus ever referred to as "Eternal Father", the Jews translate the Hebrew as Father of eternity, which is what Jesus is since he is the first born of the dead. Also a central tenet of the Trinitarian doctrine is Christians should “neither confound the Persons nor divide the Substance” (Athanasian Creed) of the Trinity. The Hebrew for Mighty God is "gibowr 'el", which can be translated "mighty ruler" as in Ezekiel 31:31. Now put vs. 6 in its full context and what you find is a description of God's Anointed who will come from David's line and reign over Israel for eternity.
In Hebrew culture the eldest son was due all the titles, honor, privileges, and etc. due his father, therefore any title given to the Father can be applied to Jesus His son without that meaning Jesus is God. Also in the Hebrew usage of "el", "elohiym", and other words for "god" can also be applied to human beings, therefore the Psalmist wrote that the Jews were "gods" (John 10:34).
Since Luke was written in Greek not Hebrew the word used by Elizabeth was "kurios". However since you want to appeal to Hebrew:
Psalms 110:1
The LORD says to my Lord:
"Sit at My right hand,
Until I make Thine enemies a footstool for Thy feet."
NAS
Yaweh says to my "adown" not "adonai".
The rest of your NT proofs are refuted on this forum so I will not repost that information.
The Trinity is a doctrine that is not supported in Scripture and is the invention of Greeks who used Greek philosophy to interpret books written by Jews.
Now, do you think you can address just the three Scriptures I posted or are explicit statements made by both Jesus and Paul more than you can handle? Trying to avoid those statements implies you cannot refute them and that you are labeling both Jesus and Paul liars.
