Is Deuterocanonical books (Labelled by Protestants as: "Apocrypha"), really part of the Septuagint?

Yes — the Deuterocanonical books were truly part of the Septuagint (LXX).
This is not speculation; it is a well-established historical fact supported by:

• Ancient manuscripts

• Jewish historical usage

• Early Christian writings

• The structure of the early Greek Bible

Let me explain it clearly and simply.

---

⭐ 1. What exactly is the Septuagint?

The Septuagint (LXX) is the Greek translation of the Hebrew Scriptures, begun around 250–100 B.C. in Alexandria, Egypt.

It became the Bible of:

• Greek-speaking Jews (Diaspora Jews)

• Jews living outside Judea

• The early Church (1st–4th century)

---

⭐ 2. Were the Deuterocanonical books included in the Septuagint?

YES. They were fully included.

The Septuagint manuscripts include:

✔ Tobit

✔ Judith

✔ Wisdom of Solomon

✔ Sirach (Ecclesiasticus)

✔ Baruch

✔ 1 Maccabees

✔ 2 Maccabees

✔ Additions to Esther

✔ Additions to Daniel (Susanna, Bel & the Dragon, Song of the Three Holy Children)

These books are found in every major ancient Septuagint manuscript.

---

⭐ 3. Proof: Ancient Manuscripts

The oldest complete Christian Bibles — all based on the Septuagint — contain the Deuterocanonicals:

📘 Codex Vaticanus (4th century)

Contains:

• Wisdom

• Sirach

• Judith

• Tobit

• Baruch

• Additions to Daniel & Esther

📘 Codex Sinaiticus (4th century)

Contains:

• Tobit

• Judith

• Wisdom

• Sirach

📘 Codex Alexandrinus (5th century)

Contains:

• All Deuterocanonical books

• 1–4 Maccabees

These are the oldest biblical manuscripts we have, and they show the Deuterocanonicals as standard books of Scripture.

---

⭐ 4. Early Jews and Early Christians Used These Books

Jews in the 1st century

Diaspora Jews (outside Israel) used the Septuagint with the Deuterocanonicals included.

We know this from:

• Philo of Alexandria

• Josephus (quotes some Deuterocanonicals)

• Jewish inscriptions

• Synagogue fragments

Jesus and the Apostles

Their Bible quotations, preserved in Greek, match the Septuagint, not the Hebrew Masoretic Text.

And the Septuagint they used already contained the Deuterocanon.

---

⭐ 5. Early Church Fathers Confirm It

Church Fathers (1st–4th century) quote these books as Scripture because they inherited the Septuagint from the Apostles’ generation:

• Clement of Rome (1st century) quotes Wisdom & Sirach

• Irenaeus (2nd century) quotes Baruch, Wisdom, 2 Maccabees

• Origen includes them in his Hexapla

• Augustine defends them as Scripture

• Councils of Rome (382), Hippo (393), Carthage (397) list them as Scripture

All based on the Septuagint tradition.

---

⭐ 6. When were they removed?

Protestants later removed these books in the 16th century (Reformation).

But for more than 1,500 years, the Christian Bible (based on the LXX) included the Deuterocanonicals as normal Scripture.

They were not added by Catholics —
they were removed by Protestants.

---

⭐ FINAL ANSWER

YES, the Deuterocanonical Books were absolutely part of the Septuagint.

They appear in:

• the oldest Septuagint manuscripts

• the early Christian Bibles

• early Jewish and Christian usage

• patristic quotations

• the biblical canon of the early Church

The idea that they were “not part of the Septuagint” is historically false.

⭐ FINAL CONFIRMATION

The Deuterocanonical books were fully included in the oldest complete Greek Bible manuscripts:

• Codex Vaticanus

• Codex Sinaiticus

• Codex Alexandrinus

This proves beyond doubt that:

✅ They were part of the Septuagint

✅ They were considered Scripture

✅ They were used by Jews and Christians before the time of Jesus

✅ They were used by the early Church for 1,500 years before the Reformation

⭐ WHAT DOES “SEPTUAGINT” REALLY MEAN?

The word Septuagint comes from the Latin word septuaginta, which means “seventy.”

✔ Septuagint = “The Seventy”

It is often abbreviated as LXX, the Roman numeral for 70.

---

⭐ WHY IS IT CALLED THE SEVENTY?

Because of an ancient Jewish tradition recorded in the Letter of Aristeas:

📘 72 Jewish scholars (rounded to “70”) were brought to Alexandria, Egypt

📘 They translated the Hebrew Torah into Greek

📘 Each translator worked separately

📘 Miraculously, all their translations matched

This story is symbolic, but the important part is:

👉 The translation was highly respected by Greek-speaking Jews
👉 It became the standard Scripture of the Jewish Diaspora
👉 It later expanded to include the Prophets, Writings, and Deuterocanonical books

---

⭐ WHAT IS THE SEPTUAGINT?

The Septuagint (LXX) is:

✔ The oldest Greek translation of the Hebrew Scriptures

✔ Started around 250–100 BC

✔ Used by Jews living outside Israel

✔ The Old Testament used by Jesus, the Apostles, and the early Church

✔ A Bible that includes the Deuterocanonical books

---

⭐ WHO USED THE SEPTUAGINT?

✔ Jews in Egypt, Greece, Turkey, Syria, and Italy

✔ Jesus and the Apostles (NT quotations follow the Septuagint text)

✔ The Early Church Fathers

✔ The first Christian Bibles (Codex Vaticanus, Sinaiticus, Alexandrinus)

The Septuagint was the Bible of Christianity for the first 300–400 years.

---

⭐ WHY IS THE SEPTUAGINT IMPORTANT?

Because:

✔ It preserves older Hebrew readings (older than the Masoretic Text)

✔ It includes books that the early Christians considered Scripture

✔ It was the translation used in most early Christian preaching

✔ Many New Testament quotes match the LXX, not the Hebrew text

Example:
Isaiah 7:14 (LXX) — “a virgin shall conceive”
Isaiah 7:14 (Hebrew MT) — “a young woman”

The New Testament follows the LXX reading.

---

⭐ SUMMARY

Septuagint (LXX) means:

“The Seventy” — the ancient Greek translation of the Old Testament, begun by about 70 Jewish scholars.”

It is the Old Testament used by:

• Jesus

• The Apostles

• The early Church

• The first Christian Bibles

And it includes the Deuterocanonical books.
