Terry, I understand the concern—it’s a fair question to ask how Jesus, if fully God, can also speak of being “sent” without implying two separate divine consciousnesses. But here’s the key difference: in the Oneness view, Jesus is not two persons talking to each other, nor is God suffering from anything like Dissociative Identity Disorder. Rather, Jesus is one Person with two natures—fully God and fully man (Colossians 2:9). When He speaks of being sent, He is speaking as a man, fulfilling the redemptive plan of the eternal Spirit who indwelt Him (John 14:10; 2 Corinthians 5:19). It was the eternal, invisible Spirit—whom Jesus called “the Father”—that sent the man Christ Jesus into the world, not a separate divine person sending another divine person. This is not fragmentation or division within God—it is manifestation.
The Son was begotten in time (Luke 1:35), and His mission was orchestrated by the eternal God who became visible in Him. The “sending” language reflects the redemptive mission, not a split within God’s identity. So rather than picturing God as fragmented or divided, the Oneness view sees a unified, sovereign God who, in love, entered into His own creation in a real, flesh-and-blood body to redeem mankind. That’s not disorder—it’s divine condescension in the most beautiful form: Emmanuel—God with us.
I see the sarcasm in your question, but it does give an opportunity to clarify what Oneness theology actually teaches—and perhaps correct a misunderstanding. Oneness theology does not teach that God “was once Yahweh but no longer is,” or that Jesus “was once Jesus of Nazareth but no longer is.” Rather, we affirm that Yahweh is the eternal Spirit, the one true and living God, who in the fullness of time manifested Himself in flesh as Jesus of Nazareth (1 Tim. 3:16). That same Spirit never ceased to be God while dwelling fully in the man Christ Jesus (Col. 2:9). After the resurrection and ascension, Jesus is now glorified—but He does not cease to be human. Instead, He remains the visible, glorified image of the invisible God (Heb. 1:3; Rev. 1:13–18). He is both Lord and Christ (Acts 2:36), both God and man, and He forever bears the name that is above every name (Phil. 2:9–11).
So no, we do not believe God switched roles or discarded identities. We believe the eternal God revealed Himself progressively and simultaneously—as Father in creation, as Son in redemption, and as Holy Ghost in regeneration. These are not separate persons but distinct manifestations of the same indivisible God, whose fullness now and forever dwells in the glorified Christ. Jesus is not “of the cosmos” in some vague cosmic identity—He is Yahweh revealed, the Lamb upon the throne, and the only name by which we must be saved (Acts 4:12).
