Matthew ch.4:11PHB"Then Yeshua said to him, “Depart Satan, for it is written: 'You shall worship THE LORD JEHOVAH your God and him(note the singular personal pronoun) ALONE shall you serve.'"
If the the object of our devotion is a mystical union of co-equals obviously their would be no single person anywhere who is entitled to exclusive devotion even if ,as some have, we make the entire union a single person,thus adding a forth person to our supposed triad. Trinitarians insists that each member of the trinity is entitled to the highest worship effectively meaning that no member of their mystifying concept including the trinity(quadrinity?) Himself is entitled to exclusive devotion
John ch.1:18ASV"No one has seen God at any time. The only begotten [h]Son, who is in the bosom of the Father, He has declared Him."
The coming to earth of our Heavenly Father's nearest and dearest Child was meant to make JEHOVAH plain to his people this is most certainly not the case with the logos of Christendom.
