Many confuse the plurality of human beings (pl) with the Being of God and try to make the interpretation that one is the same as the other. However, when you think of baseball you might see were the difference lies.
In basebal there is the term RBI's that legally should be interpreted as RUN BATTED IN'S however it doesn't mean that does it? It REALLY means RUNS (pl) BATTED IN, RBI's The concept is the same when we speak of human BEINGS (pl), that should REALLY be stated as HUMANS (pl) being. or singular HUMAN BEING.
So that when we see say 100 human beings (pl) we should REALLY BE SAYING 100 of the HUMANS (pl) BEING.
Funny how we do that, but we get the drift anyway.
When it comes to GOD though the is ONLY ONE TRUE GOD BEING, that is the BEING that consist of the nature of the ONE TRUE GOD. However, there are 3 DISTINCT PERSONS, FATHER, SON, and HOLY SPIRIT that have the very nature consistent with the nature of the ONE TRUE GOD BEING. So it can be said there is ONE "WHAT" (GOD) but 3 "WHO's", who are the ONE GOD.
