I’m missing the book name in your request — which Bible book do you mean?

If you aren’t sure, here’s a brief, evangelical-friendly summary of who is most often considered the author for several commonly asked books (and a note where there’s significant debate).

– Genesis–Deuteronomy: Traditionally Moses. Evangelicals typically affirm Mosaic authorship while recognising editorial activity and later additions/compilations.
– Joshua: Traditionally Joshua; evangelicals often accept this while allowing later editorial shaping.
– Judges/Ruth/1–2 Samuel/1–2 Kings: Often attributed to prophets or a prophetic school (e.g., Samuel, Nathan, Gad) and later compilers; evangelicals accept prophetic/early-historic origins with editorial shaping.
– 1–2 Chronicles, Ezra, Nehemiah: Traditionally linked with Ezra (a priest/scribe) as compiler/author or with chronicler school. Evangelicals usually accept a postexilic chronicler tradition.
– Psalms: Attributed primarily to David, but many psalms are ascribed to other authors (Asaph, Sons of Korah, Solomon). Evangelicals accept Davidic core authorship alongside multiple contributors.
– Proverbs/Ecclesiastes/Song of Solomon: Largely Solomonic (Proverbs collects sayings of Solomon; Ecclesiastes traditionally Solomon though authorship is debated). Evangelicals often hold traditional Solomonic links but admit uncertainty for some books.
– Isaiah: Traditionally the prophet Isaiah. Many conservative evangelicals maintain single-author Isaiah (chapters 1–66) while some evangelical scholars accept multiple authors (Deutero-/Trito-Isaiah).
– Jeremiah, Ezekiel, Daniel: Traditionally named prophets (Jeremiah, Ezekiel, Daniel). Evangelicals typically accept prophetic authorship, with some critical discussion about dating and composition, especially in Daniel.
– The Gospels:
– Matthew: Traditionally Matthew the tax collector/apostle. Evangelicals commonly affirm Matthean authorship.
– Mark: Traditionally John Mark, associated with Peter’s teaching. Evangelicals commonly accept Mark as Peter’s interpreter’s account.
– Luke: Traditionally Luke the physician, companion of Paul; evangelicals generally accept Lucan authorship for Luke–Acts.
– John: Traditionally John the Apostle. Many evangelicals accept Johannine authorship for the Gospel and Revelation (though Revelation’s attribution has some early dispute).
– Acts: Traditionally Luke. Evangelicals accept Luke–Acts as a two-volume work by Luke.
– Pauline epistles (e.g., Romans, 1–2 Corinthians, Galatians, Philippians, etc.): Traditionally authored by Paul. Evangelicals overwhelmingly accept Pauline authorship for the undisputed letters (Romans, 1–2 Corinthians, Galatians, Philippians, 1 Thessalonians, Philemon). Some letters (Ephesians, Colossians, 2 Thessalonians, Pastoral Epistles) are debated; many evangelicals still affirm Pauline authorship of the Pastorals (1–2 Timothy, Titus), though some evangelical scholars view them as pseudonymous or by Paul’s circle.
– Hebrews: The author is anonymous in the text. Historically, some church fathers attributed it to Paul, but modern evangelical scholarship is divided — many now accept the author is unknown (proposals include Barnabas, Luke, Apollos, or an unknown Pauline associate). Conservative evangelicals differ: some still affirm Pauline authorship; others accept anonymity.
– Revelation: Traditionally John the Apostle (John of Patmos). Many evangelicals accept Johannine authorship, though a minority distinguish the author from the Gospel’s John.

If you tell me the specific book you meant, I can give a focused evangelical perspective: internal and external evidence, historical patristic testimony, key scholarly positions, and why most evangelicals accept or question that authorship.
