The Catholic Church affirms that Hebrews 1:8, which applies Psalm 45:6-7 ('Your throne, O God, is forever and ever') to the Son, constitutes a direct affirmation of Christ's divinity. The Letter to the Hebrews is interpreted within Catholic tradition as establishing Christ as the definitive revelation of God, the 'radiance of his glory and the exact imprint of his nature' (Hebrews 1:3). The Catechism of the Catholic Church (§§ 465-469) cites this passage as evidence of Christ's equality with the Father and His divine nature.

Catholic exegesis, drawing on patristic sources and modern papal documents, understands this passage as the author of Hebrews making an explicit scriptural argument for Christ's superiority over the angels and His divine status. The application of 'God' (Gk. ho Theos) to the Son is seen as a deliberate Christological statement, particularly striking given the Jewish monotheistic context. This supports the Nicene definition of Christ as homoousios (of one substance) with the Father.
