That’s a classic
Oneness / Modalist argument heresy, blending truth (Christ’s divinity and unity with the Father) with a denial of the distinct Persons within the Godhead. Scripture shows that
Christ contains the fullness of the Godhead because He
shares the divine essence — not because He
is the entire Trinity by Himself.
I appreciate the Scriptures you quoted — all true, but we must handle them in harmony, not isolation. The fullness of the Godhead dwelling in Christ doesn’t mean Jesus
is the Father and the Spirit; it means the
one divine nature of God is fully present in Him.
Colossians 2:9 (KJV) says,
“For in him dwelleth all the fulness of the Godhead bodily.”
That verse speaks of essence, not identity collapse. The same divine fullness also belongs to the Father and the Spirit because they share one essence — not because they are one Person.
If Colossians 2:9 KJV meant Jesus
is all three Persons, then His prayers to the Father (John 17:1 KJV) and His promise to send “another Comforter” (John 14:16 KJV) would make no sense.
Jesus wasn’t pretending to talk to Himself; the Son was communing with the Father through the Spirit — three distinct Persons acting in perfect unity.
When Scripture says,
“The Lord our God is one Lord” (Deuteronomy 6:4 KJV), it’s affirming
oneness of being, not singleness of Person. The Hebrew word
’echad for “one” often denotes a
compound unity — like “one flesh” (Genesis 2:24 KJV) referring to two individuals joined as one.
The Father is not the Son, the Son is not the Spirit, yet all are the same one God — co-equal, co-eternal, and inseparable in will and essence.
That’s why 1 John 5:7 KJV says,
“These three are one,” not “these three are the same Person.”
God’s Word presents unity without confusion and distinction without division.
The mystery is profound — but not contradictory.
