The very definition of God, all knowing, all powerful, everywhere at once.....refutes it. If there was more than one God they would neither be everywhere at once, as they would share their real estate. They would also share knowledge and neither would have all knowledge of all actions because some actions would be unique to both and without knowledge of each other. By the very definition of God...there is only one God. The great shema, Jews had it right. If there was more than one God, none of them would truly by definition, be God.
You are treating knowledge as if it is a chair of which only one person can posses.
1+1 = 2, I know that and you know that, billions of billions of people know that 1+1 = 2. Clearly more than one God could know that also, they could have a shared knowledge of all things.
all powerful? What does that mean? I would assume in your mind it means the power to create thus the energy to do it.
Matt 28 “And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth.”
The word ‘all’ means “collectively”. The word power does not just connote energy but “the power of authority (influence) and of right (privilege)” (Strongs Bible Concordance)
All power = all authority over creation.
John 10
17 Therefore doth my Father love me, because I lay down my life, that I might take it again.
18 No man taketh it from me, but I lay it down of myself. I have power to lay it down, and I have power to take it again. This commandment have I received of my Father.
John 17
1.…Father, the hour is come; glorify thy Son, that thy Son also may glorify thee:
2 As thou hast given him power over all flesh, that he should give eternal life to as many as thou hast given him.
Matt 9 we’ve got two here
5 For whether is easier, to say, Thy sins be forgiven thee; or to say, Arise, and walk?
6 But that ye may know that the Son of man hath power on earth to forgive sins, (then saith he to the sick of the palsy,) Arise, take up thy bed, and go unto thine house….
8 But when the multitudes saw it, they marvelled, and glorified God, which had given such power unto men.
John 5,
21 For as the Father raiseth up the dead, and quickeneth them; even so the Son quickeneth whom he will.
22 For the Father judgeth no man, but hath committed all judgment unto the Son:
26 For as the Father hath life in himself; so hath he given to the Son to have life in himself;
27 And hath given him authority to execute judgment also, because he is the Son of man.
In that list there is the authority of the resurrection, the authority to heal, forgive and judge.
There are other powers which he demonstrates, the power to sees what he wants, he saw Nathanael under the tree. The power to read men’s minds.
And the power over the elements of the earth, he commands the waves to be still. That power would be the power of creation which God the Father gave him, Heb 1
My point here is that God the Father shared his power or authority to act with Jesus.
Mark 3
14 And he ordained twelve, that they should be with him, and that he might send them forth to preach,
15 And to have power to heal sicknesses, and to cast out devils:
It is possible for Jesus to also share this power even to the point of having power over the elements because by faith we can move mountains.
Rev 3
21 To him that overcometh will I grant to sit with me in my throne, even as I also overcame, and am set down with my Father in his throne.
There is only one seat or throne of power but God doesn’t mind sharing it.
