Now please don't make the assumption here that the important issue lies in the use of the correct names, as the Sacred Name movement holds.  It is rather in understanding the correct relationships between Father, Son, and Spirit.  The Father, Yah Yahweh, is supreme, yet grants all power and all authority over all which is created, to the Son.  The Son, Yashua Yahweh, the creator of the heavens (the universe) and the earth, is equal to the Father, yet obedient to Him, sub-servant.  Spirit is their essence, what they are.  Spirit is unapproachable light, different from matter and energy; greater.
HPWells:  I suggest that you have the right to follow your chosen religion, but please stay out of ours.  Us "pagen Christians" have enough variance within our own belief structure, and don't need outsiders meddling, adding fuel to the fire.  And you have the written Torah?  We have Torah written in our hearts.  Even better!  We do by instinct, what you have to be forced to do by Jewish law.
