I’m missing the book name in your question — you wrote “the most-likely Bible author of ”.” Which book or passage do you mean?

To help you decide, here’s a short primer on how many evangelical Christians approach Bible authorship and a few examples of common attributions (so you can pick the book you want more about):

– Evangelical approach in brief
– Generally gives a high view of Scripture and gives significant weight to the Bible’s own internal claims and early church testimony.
– Uses historical-grammatical interpretation and engages with critical scholarship, but often prefers traditional attributions unless there is strong contrary evidence.
– Where scholarship raises questions, many evangelicals look for explanations that conserve historic authorship while accounting for textual and historical data.

– Common traditional evangelical attributions (examples)
– Genesis–Deuteronomy (the Pentateuch): traditionally Moses (with allowance by many evangelicals for later editing/compilation).
– Psalms: many by David; others by Asaph, the Korahites, Solomon, etc.
– Proverbs, Ecclesiastes, Song of Solomon: largely Solomon (though Ecclesiastes and some proverbs have more complex transmission histories).
– Isaiah: many evangelicals affirm single-author Isaiah (the prophet Isaiah) and accept his far-reaching prophecy; some accept critical proposals of multiple authors (Deutero-/Trito-Isaiah), but influential evangelical scholars (e.g., John Oswalt) defend unity.
– Daniel: many evangelicals affirm the historic prophet Daniel (some critical scholars propose a later date; evangelicals argue for predictive prophecy and historical fit).
– Matthew, Mark, Luke, John (Gospels): traditionally Matthew (the tax collector/apostle), Mark (companion of Peter), Luke (physician and companion of Paul), John (the apostle). Evangelicals typically accept these attributions.
– Acts: Luke (the same Luke who wrote the Gospel).
– Hebrews: historically debated. The early church and many evangelicals (e.g., F. F. Bruce historically) attributed it to Paul; others question Pauline authorship because of style and anonymity. Many evangelicals still allow for Pauline authorship or a Pauline associate.
– Revelation: traditionally John of Patmos, often identified with John the Apostle by many evangelicals (though there is some debate).

If you tell me the specific book (or passage) you meant, I’ll share an evangelical Christian perspective on the most likely author, including the internal and external evidence, main scholarly debates, and representative evangelical scholars who defend that view.
