Kimbanguist theology affirms that Hebrews 1:8 (quoting Psalm 45:6) presents God the Father addressing the Son as 'God,' clearly affirming the deity of Christ. This passage is understood as explicit biblical testimony to Christ's full divinity. The Kimbanguist emphasis on Christ as God's supreme revealer and the central figure of faith is rooted in passages that affirm his divine nature and authority. Hebrews 1:8 is cited as evidence that Christ is not merely a created being or an exalted creature but is truly God.

The prophetic tradition of Kimbanguism, which honors Simon Kimbangu as a prophet sent by God, is consistent with affirming Christ as fully divine. God sends prophets, but Christ is God in a unique and singular way — the Word who was God from the beginning.
