Indeed there ‘could’ be three, but God says He is one. So who then is Jesus?Homer's point was that if all three are "fully God" even outside the confines of the "godhead" (the Creeds state the Jesus was "fully God and fully Man") then how could this not mean that there are Three Gods?
Jesus says He and the father are one. Ok, then they are One. I do not see why three parts could not be one. They all share the same substance and divinity, because ‘they’ say they do. I do not see any problem with this in relation to God, for God is not man (or even close) therefore trying to force the created humans concept of personhood around a being that is quite possibly larger and more dynamic than space and the whole Universe, does not make sense (like trying to say what happens in a fish bowl happens in the ocean). I am sure the sheer size and dimensions of God demand that His 'persons' or ‘personhood’ cannot be limited to our human concept of personhood.
‘Therefore’ I can revert back to believing that it makes sense that if God (super magnificent and incomprehensible) says He is One, and Jesus ‘also’ says He is One with the One God, then, If I want to believe Jesus, I find no other alternative but to believe He and the Father are One God (and Modalists can't make sense of the communication and distinctions between them).
Like I asked on the other thread; Who do you call Lord?
