Trinitarianism is polytheism, Trinitarians make God into nothing but a class of individuals. You put the persons before the essence. That is directly against Deuteronomy 6:4 "Hear O Israel, the Lord is God, the Lord is one"
God is ONE. The Father is how God reveals himself to creation, the Son is how God reveals himself in Jesus Christ, and the Holy Ghost is how God reveals himself to the Christian Church. Scripture does not teach Trinitarianism, it teaches Oneness. This was the teaching of the Apostles and this is what Apostolic Christians who have received baptism of the Holy Ghost believe in today because the Holy Ghost speaks through us.

>Believest thou not that I am in the Father, and the Father in me? the words that I speak unto you I speak not of myself: but the Father that dwelleth in me, he doeth the works.
>John 14:9-10
>Now the Lord is that Spirit: and where the Spirit of the Lord is, there is liberty.
