1 Corinthians 15:28
1 Corinthians 15:2828And when all things have been subjected to Him, then the Son Himself will be made subject to Him who put all things under Him, so that God may be all in all.
JWs treat as their strongest proof-text against the Trinity: "the Son himself will also subject himself to the One who subjected all things to him, so that God may be all in all." If the Son subjects himself to the Father permanently, he cannot be equal to God. The verse is read as teaching eternal ontological subordination — not merely a functional arrangement within the economy of redemption.
The "subjection" in verse 28 is the completion of the incarnate Son's redemptive mission and the return to the pre-incarnation relationship — not an ontological statement about inferior nature. has Jesus asking the Father to glorify him "with the glory I had alongside you before the world was," pointing to a shared glory that precedes the incarnation. A general who voluntarily returns command to a king after winning a war is not proving he is less human than the king — he is completing his commission. Paul's logic in verse 27 is telling: he must explicitly exclude the Father from those subjected to the Son ("it is evident that this does not include the One who subjected all things to him"). The exception only needed to be stated because the Son's authority is so comprehensive that without the qualifier it would logically include the Father. That is divine- scale authority, not creaturely subordination.
