El Gibbor — The Mighty God
Jesus is a Mighty God but not THE Almighty God.
The identical Hebrew phrase El Gibbor is used for both the Messiah and Jehovah within one chapter. This creates a logical fork: either Jesus is Jehovah, or there are two Mighty Gods — which contradicts JW monotheism.
The same exclusive divine title is applied to both Jehovah and the Messiah within one chapter of the same book.
It says Mighty God, not Almighty God — there's a difference.
El Gibbor is the same title used of Jehovah in the very next chapter. The Hebrew is identical. There is no textual distinction.
He is the Father of Eternity because through his blood people can receive eternity.
'Father of Eternity' is a title describing who he IS, not what he GIVES. The text says his name shall be called these things — they are identity titles.
The four titles in Isaiah 9:6 are just messianic descriptors — a poetic list, not a claim about divine identity.
Each of the four is divine-identity language and the stack is deliberate. 'Wonderful Counsellor' — says no creature is God's counsellor; only God has the wisdom the title names. 'Mighty God' (El Gibbor) — the identical phrase is applied to Jehovah Himself in , the very next chapter. 'Father of Eternity' (Avi-Ad) — a title no creature whose existence is bounded can carry; it names the one who authors and possesses eternity. 'Prince of Peace' — the same Hebrew shalom-rule attributed to Jehovah throughout the Psalms (29:11; 85:8-10). Read together they are not four polite compliments; they are four identity-claims confessing that the child born is the God who appeared in the Old Testament.
Don't get sidetracked by the 'Mighty vs Almighty' deflection. Stay on the identical Hebrew phrase.
