What is the difference between Oneness and Trinity teaching?
Both teachings confess one God, and both confess that Jesus Christ is God come in the flesh. They differ on how the Father, the Son, and the Holy Spirit relate within that one God. Trinity teaching, as it was settled by the councils of the fourth and fifth centuries, says God is one in essence and three in persons — Father, Son, and Holy Spirit as three distinct persons, eternally co-equal. The word "Trinity" itself does not appear in Scripture, and the Doctrine page traces, from the standard histories, how that vocabulary developed over several centuries of controversy. Oneness teaching — the confession of this site — says the Bible's distinctions are not distinctions of persons: there is one God, indivisible, who has revealed Himself as Father in creation, through the Son in redemption, and as the Holy Ghost in the believer. "Son" names the incarnation — God manifest in flesh — not a second person alongside God.
"Hear, O Israel: The LORD our God is one LORD:"
— Deuteronomy 6:4 (KJV)
"One Lord, one faith, one baptism, One God and Father of all, who is above all, and through all, and in you all."
— Ephesians 4:5–6 (KJV)
The difference shows in practice as well as in confession. Trinitarian baptism is administered in the titles of Matthew 28:19; Oneness believers baptize in the name of Jesus, as the book of Acts records the apostles doing, understanding the name of the Father, Son, and Holy Ghost to be Jesus. And Father–Son language in the epistles, read the Oneness way, is incarnation language — it tells how grace reaches us: the holy God who must judge sin stepped into creation and bore the punishment Himself, in the man Christ Jesus.
