One God Not Three — The Trinity Tested Under Rule 1
The trinity doctrine states that God exists as three distinct persons — Father, Son, and Holy Spirit — sharing one divine essence. This doctrine was not present in the church from the beginning. It was formalised at the Council of Nicaea in 325 AD, nearly three hundred years after the apostles wrote. Under Rule 1 it must be tested against the text rather than assumed.
The Starting Definition — John 4:24
> John 4:24 — God is a Spirit: and they that worship him must worship him in spirit and in truth.
Jesus himself gives the foundational definition of God. Not three persons sharing one divine essence. One Spirit. This is not a peripheral verse. It is Jesus ‘s direct answer to the woman at the well when she asks where God should be worshipped. God is a Spirit. Everything else in the investigation of God ‘s nature builds from this definition.
The Word Is Not a Separate Person — It Is the Spirit in Expression
> Ephesians 6:17 — Take the helmet of salvation and the sword of the Spirit, which is the word of God.
>
> John 1:1 — In the beginning was the Word, and the Word was with God, and the Word was God.
The sword of the Spirit is the Word of God. The sword is the metaphor. The Spirit is the substance. Therefore the Word in John 1:1 is the Spirit of God in expression — not a separate person alongside God, but God expressing Himself. The Word was God because the Spirit expressing itself is the Word. The Word and the Spirit are the same substance: one as the underlying reality, one as the expression of that reality.
Three Roles, Not Three Persons
> John 10:30 — I and my Father are one.
>
> John 14:9 — He that hath seen me hath seen the Father.
>
> John 14:26 — The Father will send the Comforter in my name.
Three statements that are conclusive under Rule 1. I and my Father are one — not two persons in agreement, one. He that hath seen me hath seen the Father — not has met my Father, has seen. The Father sending the Comforter in Jesus ‘s name — the Spirit sending Himself under the name of the Son. Three roles. Father as source and sovereign. Word as expression and incarnation. Holy Ghost as the Spirit active in the world after the ascension. One Spirit in three roles.
The Trinity Was Not in the Church Before Nicaea
The disputes that led to the Council of Nicaea were about the precise relationship between the Father and the Son — not about whether there were two or three persons. Nicaea formalised the three-person formulation and inserted it into creed using Greek philosophical vocabulary (homoousios — of one substance) that is not in the biblical text. Under Rule 1 what was inserted at Nicaea carries no more authority than any other council decision. Only the text speaks. The text says God is a Spirit. Three roles. One Spirit.
