Turn to Deuteronomy 34 and read verse 10: "And there arose not a prophet since in Israel like unto Moses, whom the LORD knew face to face." Look closely at the word "since." It looks back on Moses's death from some later point. Then turn to Romans 16:22, where a man named Tertius interrupts Paul's letter to greet the readers himself, because he was the one holding the pen. Two of the most trusted names in the Bible, and in each case the text itself shows another hand at work.
What should a reader do with that? The traditional authors have serious, informed defenders, and the challenges against them are real but narrower than the footnotes suggest. The church also never built its trust on bylines alone. It received books whose authors it could not name, tested writings against the faith already handed down, and confessed that God was at work in human writers. Most doubts about the Bible's authors belong mainly to one of three layers: who wrote the book, whether the writer can be trusted, or what makes any of it Scripture at all. Once you know which layer your own doubt lives in, you know what kind of evidence could actually help.
Over four sessions you will practice that diagnosis on real cases: the end of Deuteronomy, the puzzle of Cain's wife, the letters some scholars doubt Paul wrote, and the charge that Paul contradicted Jesus. You will read the passages the debates turn on, weigh scholars from Jude 3 Project podcast conversations in their own words, and finish by rewriting your own question and voicing it in a real conversation.
