What does the past tense "hath spoken" in Hebrews 1:2 mean?
The past tense “hath spoken” in Hebrews 1:2 indicates a past, finished transaction: God, who spoke in times past through the prophets, has now spoken in these last days by His Son. This means divine revelation is complete, so claims of further special revelation contradict Scripture.
Les explains that the phrase “hath spoken” is in the past tense, showing that God’s speaking in these last days by His Son was a finished transaction. He uses this to refute people who claim grandiose visions or special revelation above what is in the Bible, saying Scripture is finished and there is no further revelation. The same pattern appears in Revelation: the ascended Lord reveals to John, and the Holy Spirit is instrumental, but the Lord Jesus is the one speaking. Les also notes that Hebrews 1:2 presents Christ as Creator, appointed heir of all things, by whom God made the world.
God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets,
