Lets do what MOST Trinitarians do NOT do.
Lets delve deep and be a barean Jew and understand the true meaning of ISAIAH 9:6.
Trinitarians say their faith is a mystery, yet it is more of a mystery to others trying to understand why they believe Isaiah 9:6, proves the Trinity.
We may not always help people see or understand the truth, often because of human pride, but at least when the end comes, people cannot say they were not told.
And I favour the Codex Sinaiticus.
St John DEFINES Jesus perfectly in John 1:18: The ONLY BEGOTTEN God.
As we already know Jesus is the second greatest in the universe, who is: The King of Kings and Lord of Lords, and the HIGHEST of all Gods, chosen and appointed by THE ONE TRUE FATHER GOD, which makes Him (A) Mighty God.
Jesus is God, because He is the IDENTICAL NATURE and copy of His Father GOD, but He is not THE GOD, As Jesus told us Himself in John 17:3, and that’s probably why St John says: and the word was God, in John 1:1c.
