How many gods does it take to screw in a light bulb? I know the old joke seems kind of irreverent but it needs to be said; because no longer does the trinitarian simply say:" God is three persons" but you will now hear very often in addition to " God is three persons" ( 3 persons are Something scripture, nor any writer of any books of the Bible mentioned.)"God is with God" and unashamedly so. This is conceptual tritheism at it's worst, and blatantly so.
No God does not intercede for us in the presence of God! Jesus died Once for all. That means his sinless sacrifice was the intercession on our behalf. It fulfills what God demanded for sin once for all.(Hebrews 10:5-7)
Note He said: in the world; not in eternity as another person of God but in the world. I have come to do your will.(Not my human will) but your God will. You will also notice the prophecy says:"My God." The Oneness position understands these prophecies Such as (Psalm 45:7KJV) as incarnation-al and not of pre-existent conversations between God.5 Therefore, when Christ came into the world, he said:
“Sacrifice and offering you did not desire,
but a body you prepared for me;
6 with burnt offerings and sin offerings
you were not pleased.
7 Then I said, ‘Here I am—it is written about me in the scroll—
I have come to do your will, my God.
Thou lovest righteousness, and hatest wickedness: therefore God, thy God, hath anointed thee with the oil of gladness above thy fellows.The Psalm passage prophetically claims that he is God, but is he a different God from his own God? This is where the trinitarian keeps making the same distinction error because of the incarnation. Jesus is that same one God and what is prophetically in Psalm 45:7 as it refers to the coming incarnation. The very same incarnation the psalm passage and Later Hebrews 1:9 quotes from. It was Jesus divinity; that of God the Father that incarnated him as son, that also pre-existed.(John14:10)
Jesus was not only the priest but was the lamb sacrificed ie. his sinless flesh. That same sinless flesh sacrificed is what pleads our case in his priestly duties. However, it does not mean the son stands and begs God in eternity. What the trinitarian means is that God somehow begs himself (One person as God) in the presence of himself(the other person of God) in eternity on our behalf. Does it need to be said that the very idea is silly anti-biblical doctrine?
The trinitarian will be quick to say that the son of God is a term of divinity. The son even if he were a god the son as god he did not know the time of his own second coming.The trinitarian will confuse the incarnation misinterpreting, misapplying, and misquoting a passage in (John 10:30-39) to attempt to prove the doctrine.
The trinitarain will attempt to say that they understood the phrase and term:" son of God" meant he was claiming divinity and this would be known to them but careful reading of the text reveals no such thing. They clearly stated they saw a man claiming equality with the father ie. God. Now that is some fancy twisting of the text to come up with such a fanciful trick. Jesus said he and the father were One. A union of God(The Father) and son as in the incarnation.
"I and my Father are one." The Jews took up stones again to stone Him. Jesus answered them, "I showed you many good works from the Father; for which of them are you stoning Me?" The Jews answered Him, "For a good work we do not stone You, but for blasphemy; and because You, being a man, make Yourself out to be equal to God." Jesus answered them, "Has it not been written in your Law, 'I said, you are gods'? "If he called them gods, to whom the word of God came (and the Scripture cannot be broken), do you say of Him, whom the Father sanctified and sent into the world, 'You are blaspheming,' because I said, 'I am the Son of God'? "If I do not do the works of My Father, do not believe Me; but if I do them, though you do not believe Me, believe the works, that you may know and understand that the Father is in Me, and I in the Father."
We see Jesus had a limited Mind in (Mark 13:32.) No man knows the hour, or the day, of Jesus second coming no not the Angels, or even the son, but the Father Only. There is that distinction of minds and knowing. How could Jesus not know something as God? You say he is "God the son" but the passage said he did not know the time of his second coming. The trinitarian says it was the self imposed limitation which is truth, but the son or genuine humanity incarnated by God the father was that self imposed limitation. However It was not "god the son" imposing limitation. Again, Jesus genuine humanity and sonship incarnated by God was that limitation. He could have called ten thousand Angels at anytime to do his bidding as God in the flesh but chose to accomplish the work or will of the father.
God did not have two or three God minds or wills. He had 1 ultimate God mind and will and 1 limited human mind in the incarnation. Again, that is not two minds of God, or two human minds. The trinitarian seems to disregard the incarnation and confuse that in Jesus and that is where they run into trouble with conceptual tritheism in trying to force the trinity doctrine upon scripture.
(Hebrews 9:11-15)But Christ being come an high priest of good things to come, by a greater and more perfect tabernacle, not made with hands, that is to say, not of this building;
Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us.
For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh:
How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?
And for this cause he is the mediator of the new testament, that by means of death, for the redemption of the transgressions that were under the first testament, they which are called might receive the promise of eternal inheritance.
There is One mediator between God and man, the man Christ Jesus.(1st.Tim.2:5)
