Branhamism affirms Hebrews 1:8 as proof that Jesus is God, interpreting the passage as divine attestation of Jesus's full divine nature. The verse 'Your throne, O God, is forever and ever' is read as the Father directly addressing Jesus as God, confirming Branhamism's central doctrine that Jesus is the fullness of God manifested in human form. Rather than seeing a tension between Hebrews 1:8 and 1:9 ('your God has anointed you'), Branhamism harmonizes the passage by affirming that Jesus possesses the full character and attributes of God while also submitting to the Father's will and purpose in his incarnate role.

For Branham, this passage exemplifies the relationship between God's transcendent nature and its revelation through Jesus: Jesus is truly God (not merely a creature or human with divine attributes), yet functionally subordinate in his historical mission. Hebrews 1:8 is deployed by Branhamism in contrast to Biblical Unitarianism and classical Arianism, which deny Jesus's divinity. The passage supports Branhamism's claim that to believe in Jesus as God's full self-revelation is to believe in the true God.
