Hebrews 1:2
Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds;
What this passage establishes
The God who spoke in the Son is said to have made the worlds through that climactic revelation.
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
