How does the Eastern Orthodox Bible's canon differ from the Protestant Bible's canon?

1. What "more books" means in practice

Eastern Orthodox Old Testaments routinely include Tobit, Judith, additional portions of Esther and Daniel, 1–2 Maccabees, Wisdom, Sirach (Ecclesiasticus), Baruch (with the Letter of Jeremiah), and the Prayer of Manasseh—titles Protestants generally classify as Apocrypha or exclude; some Orthodox editions go further and print 1 Esdras, 3 Maccabees, or other texts, so the Orthodox Old Testament is demonstrably larger and less uniform than the Protestant one ^{[1] [3] [4]}.

2. Why the difference: textual base and history

The divergence traces to the textual base used by early Christians: Eastern Orthodoxy relies heavily on the Septuagint (the ancient Greek Old Testament used in the early Church), so books contained in the LXX were treated as canonical by many Eastern communities; Protestants during the Reformation returned to the Hebrew (Masoretic) canon used in Rabbinic Judaism, producing the shorter Old Testament that modern Protestant Bibles preserve ^{[5] [2] [6]}.

3. New Testament agreement and minority divergences

Both traditions accept the same 27-book New Testament that became broadly settled by the fourth–fifth centuries, so the major canonical difference is confined to the Old Testament; nevertheless, Orthodox practice toward some New Testament books (for example, liturgical use of Revelation varies by local tradition) reflects a degree of regional practice rather than a single rigid list across all Orthodox churches ^{[2] [7] [8]}.

4. Terminology and theological implications

Eastern Christians typically use neutral or positive terms—deuterocanonical or anagignoskomena (“worthy to be read”)—for these additional books, whereas many Protestants call them Apocrypha and restrict them to edification rather than doctrine; Orthodox churches generally make little formal distinction between protocanonical and deuterocanonical texts in doctrinal standing, treating the Septuagint books as scripture in liturgy and theology ^{[4] [1] [5]}.

5. Canon as settled law vs. living tradition

Unlike the Western tendency toward a single, juridically defined canon (as in the Council of Trent for Catholics), Eastern Orthodoxy historically has exhibited a more “fluid” or regionally varied approach: some Orthodox jurisdictions include slightly different lists and place more emphasis on ecclesial usage and patristic practice than on one infallible, universally promulgated list ^{[9] [7] [8]}.

6. Practical outcomes: translations and reading

Because of these differences, published Orthodox Bibles and study editions (e.g., the Orthodox Study Bible) and liturgical lectionaries reflect the larger Septuagint-derived corpus, while most Protestant editions omit those books or relegate them to a separate Apocrypha section (as some historical KJV/Lutheran editions did), which affects what passages are cited in sermons, doctrinal proofs, and devotional reading ^{[3] [2]}.

7. Points of contention and honest limits in reporting

Controversies center on authority and method—whether canonicity is decided by ancient councils and Church usage (Orthodox argument) or by returning to the Hebrew textual standard and sola scriptura principles (Protestant argument)—and while sources document the existence of differing canons and textual bases, detailed claims about which specific books every local Orthodox church formally "binds" vary and reflect local liturgical practice; available reporting shows orthodoxy is not monolithic on minor inclusions, and definitive statements about every jurisdiction exceed the provided sources ^{[8] [7]}.
