Jews who follow the Bible do not believe in a "triune 'gxd.'"
I've always admired Fundamentalist Protestantism's philo-Semitism (it's where I started). Unfortunately, I realize that this philo-Semitism is based on the belief that Judaism is merely a museum-exhibit relic of "pre-incarnation chrstianity." As I said, I've been there.
But sometimes Fundamentalist Protestants get carried away, as this statement that "Jews who follow the Bible believe in a 'triune gxd.'"
What's next? David HaMelekh sang Southern gospel music???
David believed in a Triune God, Father, Son, and Spirit. Read the Psalms (I.e. 2, 110, etc). Solomon in Proverbs 30, Isaiah in 9, 53, Moses in Deut 18. Jesus Christ is the Metatron, or Theophany that appeared to the Old Testament saints. Wake up before he returns and it is too late
