The Trinity - The Complete Godhead - The Universe*
Highest Authority
FATHER
SON
HOLY GHOST / SPIRIT
Dr. J. Vernon McGee noted in his writing on the Trinity a quote on the question.  "How many
persons are there in the Godhead"?  Dr. McGee quoted from the Westminister Confession of
Faith this answer, "There are three persons in the Godhead:  the Father, the Son and the Holy
Ghost:  and these three are one God, the same substance, equal in power and glory"..You
cannot find a better definition for the Trinity.
* The Universe is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter (or mankind) and energy.
