Isaiah 45:12
I have made the earth, and created man upon it: I, even my hands, have stretched out the heavens, and all their host have I commanded.
Primary
What this passage establishes
God says His own hands stretched out the heavens and commanded their host.
Why it matters in the argument
Scripture says God created alone, then the New Testament places creation in Christ. The identity claim is stronger than merely saying Jesus assisted another Creator.
Apostolic connection
Because the LORD says He created by Himself, New Testament creation passages reveal Jesus within the identity of the one Creator.
Common misunderstanding
Language such as ‘by’ or ‘through’ does not require a second creator beside God; Scripture also describes God creating by His word, wisdom, power, and will.
How to use it in conversation
Pair an Old Testament ‘created alone’ passage with a New Testament passage that attributes creation to Christ.
