If you don’t believe Paul wrote Hebrews who do you think did?
Please show me where in the Bible it says Paul wrote the Book of Hebrews. I don’t know who wrote it. No one does. It has no authorship name. That has been the argument through the years. Did Paul write it or did he not? But I do know the Bible doesn’t say. That leaves conjecture.
