The Septuagint: The Parting of the Ways — How the LXX Became the Church’s Old Testament

In the first century BCE, Greek-speaking Jews treasured their Scriptures in translation. Philo celebrated the translation’s origin each year with a festival on the island of Pharos, and the diaspora read, prayed, and studied from it. Within two centuries the same text had become a battlefield. Christians cited it against rabbinic readings, the rabbis abandoned it, and new Greek versions appeared to take its place. This final episode follows that rupture through the revisions, the scholars, and the great parchment codices it produced, from Justin Martyr’s argument with Trypho to the manuscripts that carried the Old Greek into the present.


Literary Backgrounds: Greek and Ancient Near Eastern Connections

Origen of Caesarea compiled the Hexapla between 230 and 240 CE, a work that filled roughly 6,000 parchment pages. It arranged the Old Testament in six parallel columns: the Hebrew text in square script, a Greek transliteration of the Hebrew, Aquila, Symmachus, the Old Greek, and Theodotion. The Hebrew of the ancient Near East stood first on every page, and every Greek witness answered to it. In the fifth column Origen applied critical symbols that Alexandrian scholars had developed for editing Homer. An asterisk marked words present in the Hebrew but missing from the Old Greek, and Origen usually supplied them from Theodotion. An obelus marked Greek words that had no Hebrew counterpart. A method sharpened on the epics of Greece now served the oracles of God.

The Jewish revisers each wrote in a distinct literary voice. The kaige movement, active from the late first century BCE into the first century CE, reworked the Old Greek toward the proto-Masoretic Hebrew and rendered the particle וְגַם with καί γε. Aquila of Sinope, a proselyte and disciple of Rabbi Akiva, produced a version around 125 CE so tied to Hebrew grammar that it bent Greek syntax, translating the object marker אֵת with σύν. Symmachus took the opposite road in the late second century and wrote clear, elegant Koine that carried the sense of the Hebrew into natural prose. Theodotion revised the existing Old Greek against the Hebrew, and his Daniel won such favor for its clarity that it replaced the Old Greek Daniel in most Christian Bibles.


Theological and Ethical Analysis

Justin Martyr’s Dialogue with Trypho, written around 160 CE, records the quarrel in the words of the combatants. Justin charges Jewish scholars with removing passages from their Scriptures that pointed to Christ. Trypho answers that Christian writers lean on inaccurate Greek translations that altered the original Hebrew. Both men understood that a translation carries theology, and both treated the wording of Scripture as a matter of conscience. The Greek text that Jews once used in liturgy and law now served Christian argument, and that shift moved Jewish scholars to produce versions tied closely to the standardized Hebrew.

Origen answered the confusion with transparency. He placed every competing witness side by side and marked each addition and deletion so that any reader could inspect the evidence. That labor reflects a sound ethic for handling God’s word: show the reader what the text says and where the witnesses differ. Time added an irony. Scribes who copied the fifth column often dropped Origen’s symbols and kept the added text, and the resulting Hexaplaric text became a mixed, expanded Greek that hid the shorter Old Greek readings Origen had meant to preserve. Careless copying can undo careful scholarship, and the church still carries that warning.


Old Testament Analysis and Critique

Isaiah 7:14 stood at the center of the dispute. The Hebrew reads עַלְמָה, a young woman, and the Old Greek translators rendered it παρθένος, a virgin. Aquila and Symmachus replaced that word with νεᾶνις, a young woman, which fits the narrower literal range of the Hebrew and removes the Greek text’s support for the Christian claim. The prophet introduces the verse with a promise that the Lord Himself will give a sign, and a sign from the Lord invites wonder. The Alexandrian translators chose παρθένος generations before any Christian controversy existed, and the Jewish revisers chose νεᾶνις after the controversy had begun.

The Old Testament itself forbids both the careless addition and the convenient subtraction. Moses commands Israel to add nothing to the word and to take nothing from it (Deuteronomy 4:2), and Isaiah declares that the word of our God stands forever (Isaiah 40:8). Those texts judge every community that reshapes Scripture to win an argument. The revisions of the Three aimed at fidelity to the Hebrew, yet they pushed aside a translation that earlier generations of Jews had honored in synagogue and festival. A reader who loves the Old Testament owes loyalty to the whole inherited witness and no single school’s preference.


New Testament Analysis and Critique

Matthew 1:23 quotes the Greek of Isaiah 7:14: ἰδοὺ ἡ παρθένος ἐν γαστρὶ ἕξει. The evangelist wrote in the language his readers held and cited the Scripture they already read, and the Old Greek gave him the word παρθένος. Matthew’s Gospel appeared in the first century, when the Greek translation held high regard across the diaspora. Aquila and Symmachus came later, in the second century, so the Gospel’s citation predates every revision that tried to correct it.

That sequence answers Trypho’s charge directly. Matthew did not construct a doctrine on a late Christian alteration of the text. He cited a translation that Jewish communities had read for generations, and the virgin birth stands on the wording of that Scripture. The apostles took the Greek Old Testament into the churches they planted, and the churches kept it. The parting of the ways left the Christian community holding the Bible the apostles had used.


Benefits of Reading and Implications for Christian Belief and Practice

The Septuagint survived into modern times in the large parchment codices of the fourth and fifth centuries, produced under imperial Christian patronage, and the fragile papyrus rolls of earlier centuries gave way to them. Codex Vaticanus, dated to about 325 to 350 CE and housed in the Vatican Library, preserves the purest witness to the Old Greek for most books. Codex Sinaiticus, from about 330 to 360 CE, came to light at St. Catherine’s Monastery and carries extensive corrections within a high-quality Alexandrian text. Codex Alexandrinus, from about 400 to 440 CE, preserves a heavily revised text drawn toward the Hebrew and bears witness to the expanded manuscript tradition. Reading this history shows believers how God guarded His word through generations of scribes, scholars, and patrons.

Jerome, in the late fourth century, began his work on the Old Testament by translating from the Septuagint into Latin. He then saw how far the Greek diverged from the Hebrew of his day, abandoned that plan, and translated directly from the hebraica veritas. His Vulgate established the Hebrew-priority tradition across Western Europe. The Septuagint remains the official Old Testament of the Eastern Orthodox Church, used directly in its liturgy, theology, and translation. The two great streams of Christian practice thus carry the same Scriptures by different roads. Readers who want to go deeper can open Rahlfs and Hanhart’s Septuaginta, Origen’s Letter to Africanus, Jerome’s prefaces to the Vulgate, and T. Law’s When God Spoke Greek.


Application to Christian Life Today

Every believer will meet a skeptic, a coworker, or a curious neighbor who raises Isaiah 7:14 and the word “virgin.” You can answer with confidence. Matthew cited the Greek Scripture of his day, and the Jewish revisions that challenged it arrived after the Gospel was written. Take Origen as your pattern in your own study: lay the translations side by side, mark where they differ, and keep reading until you understand why. Join a Bible study, teach a friend what you learn, and let your growing knowledge of the text become a gift to someone else in the church. God has entrusted His word to ordinary people, and He gives every believer a share in guarding and passing it on.

The sign Isaiah promised arrived in a real child born to a real virgin, and that child grew up, died on a cross for sinners, and rose from the dead on the third day. Everything the codices, the columns, and the quarrels protected points to Him. If you have never trusted Jesus Christ, turn from your sin today and ask Him to forgive you and make you His own. He will receive you. If you already follow Him, tell one person this week who He is and what He has done for you.
