I do not accept the Trinity as I believe that there is One God, Yahweh, God the Father and our Lord Jesus Christ is the Son of God.
And on that point you would be wrong. The Great Statement of God's unity in Deut 6.4 is called the Shema and is spoken by devout Jews at least twice every day.
Hear, O Israel! The Lord is our God, the Lord is one!
Shema Yisrael Adonai Elohenu Adonai echad!
IT is also the first statement of the Trinity. God's name appears 3 times Adonai Elohenu Adonai
and is then called "echad
' which is translated as ONE.
HOWEVER, the way Moses used the word echad
is NOT how the later OT authors used it. In Genesis 2:24 Moses writes "For this reason a man shall leave his father and his mother, and be joined to his wife; and they shall become one [echad
] flesh." Clearly echad
does not mean an absolute singularity, but a composite unity composed of various parts.
Clearly Israel took echad
to mean a singularity, and during the later writings it is used this way. And as I said above, when they got it wrong, God would speak thru a prophet and set it straight. Sometimes they listened, but often they would not. The issue of an absolute singularity of God was corrected in the prophetic writings, Daniel chapter seven where Daniel has a very disturbing vision. 9 “I kept looking
Until thrones were set up,
And the Ancient of Days took His seat;
His vesture was like white snow
And the hair of His head like pure wool.
His throne was ablaze with flames,
Its wheels were a burning fire.
10 “A river of fire was flowing
And coming out from before Him;
Thousands upon thousands were attending Him,
And myriads upon myriads were standing before Him;
The court sat,
And the books were opened.
13 “I kept looking in the night visions,
And behold, with the clouds of heaven
One like a Son of Man was coming,
And He came up to the Ancient of Days
And was presented before Him.
14 “And to Him was given dominion,
Glory and a kingdom,
That all the peoples, nations and men of every language
Might serve Him.
His dominion is an everlasting dominion
Which will not pass away;
And His kingdom is one
Which will not be destroyed.
28 “At this point the revelation ended. As for me, Daniel, my thoughts were greatly alarming me and my face grew pale, but I kept the matter to myself.”
Disturbing indeed. Clearly God (as understood by the Jews) was the Ancient of Days on His throne. But then a second person appears who clearly is also Deity by description. That really upsets the apple cart.
