If you believe that the Written Word of God contains only 66 books, or if you believe that only 66 books are inspired and inerrant, why is that? Catholics and Orthodox believe the bible contains at least 73 books, all of which are inspired and inerrant.
From history we can read what the Church believed to be inspired and inerrant at the Council of Rome.
“The order of the Old Testament begins here: Genesis, one book; Exodus, one book; Leviticus, one book; Numbers, one book; Deuteronomy, one book; Joshua [Son of] Nave, one book; Judges, one book; Ruth, one book; Kings, four books [ie., 1 and 2 Samuel and 1 and 2 Kings]; Paralipomenon [Chronicles], two books; Psalms, one book; Solomon, three books: Proverbs, one book; Ecclesiastes, one book; Canticle of Canticles, one book; likewise Wisdom, one book; Ecclesiasticus [Sirach], one book. Likewise the order of the Prophets. Isaias one book, Jeremias one book,…lamentations, Ezechiel one book, Daniel one book, Osee … Nahum … Habacuc … Sophonias … Aggeus … Zacharias … Malachias … Likewise the order of the historical [books]: Job, one book; Tobit, one book; Esdras, two books [Ezra and Nehemiah]; Esther, one book; Judith, one book; Maccabees, two books.” Council of Rome, Decree of Pope Damasus (A.D. 382).

At the Synod of Carthage
“[It has been decided] that nothing except the canonical Scriptures should be read in the Church under the name of the divine Scriptures. But the canonical Scriptures are: Genesis, Exodus, Leviticus, Numbers, Deuteronomy, Joshua, Judges, Ruth, four books of Kings, Paralipomenon, two books, Job, the Psalter of David, five books of Solomon [Proverbs, Ecclesiastes, Song of Songs, Wisdom, Sirach], twelve books of the Prophets, Isaiah, Jeremiah, Daniel, Ezekiel, Tobit, Judith, Esther, two books of Esdras, two books of the Maccabees.” Council of Carthage III, Canon 397 (A.D. 397).
I welcome our Orthodox brothers to share dates where in their tradition, the canon was listed as well.
