"He hath assigned no associate unto Himself in His Kingdom, no counselor to counsel Him, none to compare unto Him, none to rival His glory."

 

"AND now concerning thy reference to the existence of two Gods. Beware, beware, lest thou be led to join partners with the Lord, thy God. He is, and hath from everlasting been, one and alone, without peer or equal, eternal in the past, eternal in the future, detached from all things, ever-abiding, unchangeable, and self-subsisting. He hath assigned no associate unto Himself in His Kingdom, no counselor to counsel Him, none to compare unto Him, none to rival His glory. To this every atom of the universe beareth witness, and beyond it the inmates of the realms on high, they that occupy the most exalted seats, and whose names are remembered before the Throne of Glory."
