Now this kinda stuff is what upsets Mormons; but I do NOT understand why...
Why should it upset so called Mormon’s? It is essentially what they believe. That has always been kind of your problem. Lack of understanding.
Because you want to believe and say things that are not true relative to man’s requirements/commandments vis a vis the one true and living God.
You even laid out for all to read many verses from the Book of Mormon, that say precisely what you seem not to understand.
They believe BOTH?
Trinity and non-Trinity??
Trying to reconcile that in my head would make me reach for the Prozac©!
