It looks like the book name is missing from your question — could you tell me which book of the Bible you mean?

If you’re not sure which one to ask about, here are brief evangelical-oriented notes on a few books whose authorship people often ask about. Tell me which one (or another book) you want a fuller write-up on and I’ll expand from an evangelical perspective.

– Hebrews
– Traditional view (older evangelical tradition): Paul wrote Hebrews.
– Contemporary evangelical view: many accept that the author is anonymous; candidates suggested include Paul, Barnabas, Apollos, Luke, or another early Christian teacher. Evangelicals tend to weigh internal theology/style, early patristic testimony, and how the book fits Paul’s thought.

– Isaiah
– Traditional view: Isaiah son of Amoz wrote the whole book.
– Critical view: multiple authors (Isaiah, Deutero-/Trito-Isaiah). Many evangelicals defend single-authorship or hold that later sections are still prophetically Isaiah’s work; arguments include unity of themes and prophetic foresight.

– Deuteronomy / Pentateuch (Moses)
– Traditional evangelical view: Moses is the primary author (or the principal compiler/editor) of the Pentateuch, sometimes allowing later editorial additions.
– Critical scholarship: documentary hypothesis (JEDP). Many evangelicals reject full JEDP or adopt a modified view (Mosaic core with later redaction).

– Psalms
– Traditional view: many ascribed to David, but the Psalter is recognized as a compilation by various authors.
– Evangelicals typically accept Davidic authorship for many psalms while acknowledging other named authors (Asaph, Korah, Solomon) and anonymous psalms in the collection.

– Revelation
– Evangelical view: John the Apostle (the “beloved disciple”) or John of Patmos; majority of evangelicals accept Johannine authorship based on early church testimony and theological/literary links with John’s gospel/letters.

If you tell me the specific book, I’ll summarize the most-likely author from an evangelical perspective, including the main reasons for that conclusion (internal evidence, patristic testimony, linguistic/style notes, and theological implications).
