That is a very good question--and hits at the heart of my OP.
The answer is obvious--the Trinitarians can separate God the Father and Jesus Christ out as two separate substances--but since they cannot differentiate that in the term "God"--they have to make their minds up--does God have a body of flesh and bone--or is only a Spirit--as they ***ign both those values to each as a separate person--but cannot, as God. They are in a "pickle".
