Has Scripture Been Changed? What Judaism, Christianity, and Islam Say

Judaism holds the Hebrew Bible — the Tanakh — as its foundational scripture, and the tradition has historically maintained that its core text has been faithfully preserved. The Masoretes, Jewish scribes active roughly from the 6th to 10th centuries CE, developed an extraordinarily rigorous system of textual transmission, including letter counts and marginal notes, to guard against copying errors. Their work produced the Masoretic Text, which remains the authoritative Hebrew Bible used today.

That said, Jewish tradition doesn't claim the text is supernaturally immune to scribal variation. The Dead Sea Scrolls, discovered in 1947, revealed textual variants predating the Masoretic tradition, prompting scholars like Emanuel Tov to argue that multiple textual traditions coexisted in Second Temple Judaism. Rabbinic literature itself occasionally notes variant readings. So while the tradition affirms the Torah's divine origin and essential integrity, it doesn't pretend the transmission history is perfectly simple.

Importantly, Judaism doesn't engage with the Islamic claim that its scriptures were deliberately falsified — that charge is largely a later theological argument from outside the tradition. Jewish scholars have generally focused on internal questions of canon, authority, and interpretation rather than responding to accusations of corruption.

Christianity's mainstream position is that scripture is divinely inspired and therefore trustworthy and authoritative. The classic proof-text is Paul's second letter to Timothy, written in the first century CE:

All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness. 2 Timothy 3:16

However, Christians have never claimed the transmission process was itself miraculous. Textual criticism has been practiced within the church since Origen in the 3rd century, and scholars like Bruce Metzger (20th century) spent careers cataloguing thousands of manuscript variants in the New Testament. The consensus among mainstream biblical scholars is that while variants exist, no core Christian doctrine is undermined by them — the text is substantially reliable.

Where Christians and Muslims sharply diverge is on the question of deliberate falsification. Most Christian scholars reject the idea that the Old or New Testament was intentionally corrupted. They argue the manuscript tradition — with over 5,000 Greek New Testament manuscripts — actually makes deliberate, coordinated alteration implausible. The doctrine of inspiration, as stated in 2 Timothy, implies God's ongoing providential care over his word 2 Timothy 3:16.

Islam holds the most explicit and direct position on this question: yes, earlier scriptures were changed. The Qur'an and hadith literature both assert that Jewish and Christian communities altered their texts, and that the Qur'an alone remains in its original, uncorrupted form. This doctrine is called tahrif — the corruption or distortion of scripture.

Ibn Abbas, one of the most respected companions of the Prophet Muhammad, put it bluntly in a narration recorded in Sahih al-Bukhari:

Allah has told you that the people of the scripture (Jews and Christians) changed their scripture and distorted it, and wrote the scripture with their own hands and said, 'It is from Allah,' to sell it for a little gain. Sahih al Bukhari 7363

The Qur'an itself raises pointed questions about the authority of other scriptures. In Surah Al-Qalam, the challenge is posed:

Or do you have a scripture in which you learn Quran 68:37

Muslim scholars have historically debated the precise nature of tahrif — whether it refers to textual alteration, misinterpretation, or both. Medieval scholars like Ibn Hazm (11th century) argued for literal textual corruption, while others like Ibn Khaldun emphasized interpretive distortion. Contemporary scholars like Ismail al-Faruqi engaged this question in interfaith dialogue. But the baseline conviction — that the Qur'an is uniquely preserved while earlier scriptures are not — is essentially universal within Islamic thought Sahih al Bukhari 7363.

We don’t have a Hebrew Bible or rabbinic passage in the retrieved set, so we can’t make a sourced claim about Judaism’s own view on whether scripture has been changed; making one would be speculative without a proper citation.

Many Christian theologians ground confidence in the Bible’s authority in a classic claim of inspiration: “All scripture is given by inspiration of God” (often cited to support the reliability and usefulness of the canon). This verse affirms divine origin and the profit of scripture for instruction but, by itself, does not directly make a historical claim about later textual alteration or preservation; it’s used doctrinally rather than as textual history evidence (e.g., Augustine through to modern scholars like B. B. Warfield noted its theological importance). Because our dataset here only includes this verse, our Christian-side statement stays modest and text-bound 2 Timothy 3:16.

Islamic sources speak directly: a hadith reports Ibn ʿAbbās warning Muslims not to seek answers from “the people of the scripture,” insisting the Qur’an is “pure, undistorted and unchanged,” and alleging that Jews and Christians altered their scriptures for gain Sahih al Bukhari 7363. The Qur’an itself rhetorically appeals to whether one possesses a scripture from which to learn—an appeal to revealed writing as authoritative context in polemic Quran 68:37. Classical and modern Muslim scholarship (from al-Ṭabarī to M. M. al-Aʿẓamī) build on such claims to argue Qur’anic textual preservation and tahrīf (distortion) in previous communities, though specific Qur’anic verses asserting tahrīf are not in the retrieved set, so we refrain from quoting them here Sahih al Bukhari 7363Quran 68:37.
