Hebrews 1:8 is often used to try and support the Trinity doctrine. (It would be worthy to note that when trying to prove the Trinity, it seems the “third party” is trailing off somewhere in the dust.)
Hebrews 1:8 states,
“But to the Son He says ‘Your throne, O God, is forever”
What we are told is that Jesus is called God, therefore, Jesus the Messiah is viewed as supreme being, that is, God the Father Himself. But is this true?
Here the context proves that the word “God” does not denote God the Father. This is proven by the very next verse (v. 9) which says,
“therefore God, your God, has set you above your companions.”
We didn’t have to go very far to understand that Jesus is not the supreme God. The supreme God does not have a God!
Hebrews 1:8 is quoting Ps. 45:6-7. The context of that Psalm is of the Davidic king’s marriage to a princess from Tyre. Note the psalmist calls the king God because he represents God as God’s agent to rule over God’s people. Does this make the king the supreme God?
If Jesus is taken as the supreme God in Hebrews 1:8, then we must conclude that the Davidic king of Psalm 45:6 is also God. Jesus is called God in a “representative sense,” not as the supreme God Himself.
