I am confident in saying that Christians view themselves as monotheistic. Whether they are Unitarian or trinitarian Christians, all Christians see themselves with the belief of one God. Trinitarians, which make up the vast majority of Christianity, see God in three forms: The Father, The Son and The Holy Spirit.
If I were a Christian, this is how I would perceive it. The Father created Heaven and the Earth, found his sovereignty with the monotheistic nation of Israel, established his reign of various prophets and his covenant with them. God spoke to certain prophets of his plan to raise a man who would commit no sin and was born of a virgin, this became Jesus. When the Father created Jesus, the Father ceased to exist. Jesus lived his life as man and God, and when he died on the cross and rose from the dead, his essence was raised into Heaven, and dissolved, becoming the Holy Spirit. The Holy Spirit is the reason why humanity has thus had a huge incline in modern prophets with the sciences and liberal arts. The Holy Spirit made humans aware of their surroundings.
In this contraption I have made, The Father, The Son and The Holy Spirit exist separately from each other, but each one of them is distinctly God as we now perceive it.
However, the common trinitarian Christian argument is that all three of these Gods exist at the same time. That The Father, The Son and The Holy Spirit are all eternal. Even the Jehovah Witnesses believe Christ to first exist as Michael the Archangel.
If The Father, The Son and The Holy Spirit all exist separately and at the same time, doesn't this make Christianity a polytheistic religion? Specifically tri-theism? Think about it. Yes, I know, Christians will make the allegory that water can be solid, liquid and gas as we know them, but if the water exists as solid, liquid and gas all at the same time, doesn't that lead the distinction into three Gods rather than one?
I am very confused about all of this. Something isn't adding up. Trinitarianism to me sounds like a fancy way of calling yourself a polytheist whilst still trying to hold yourself a monotheistic way of living.
I would like to try to talk to a standard Christian about this that helps me understand this confusion I have with the religion. It really doesn't make sense to me... Now, I have heard that Unitarian Christians believe that the Father is only God, and Oneness Pentecostals believe that the Son is only God, both of these arguments make more sense to me than the commonly perceived trinitarian monotheism that is popular in Christianity today.
As far as my own beliefs, what I hold to is a pantheistic understanding of trinitarian monotheism. The Omniverse, Entropy and Extropy all exist separately from each other, none of which is God without the other two. When all of them line up perfectly with each other, we create a Superverse - which is my conception of God. But The Father, The Son, and The Holy Spirit exist separately and together at the same time, so it doesn't really make sense to call Christianity a monotheistic religion.
Please, I would like a Christian to educate me so I am less confused about this matter.
