How do we know that Christ's nature is divine?

The divinity of Christ is affirmed by His title as the 'first-born of every creature' in Colossians 1:15. This distinction indicates that Christ exists before creation and holds authority over all. His dual nature as fully God and fully man is critical; as God, He is the Creator ('by him all things were made'), while as man, He is a true member of creation. The Council of Chalcedon asserts that He is recognized not as a creature but as the Creator Himself. His unique role shows His divine authority, ensuring that He is not merely one of the creations but the one by whom all creation came into being.
