Overview
The Evidence in Brief
history
From Early Writings to Modern Bibles
Most differences are spelling, word order, or other small copying changes. A smaller group is more significant: the longer ending of Mark, the story of the woman accused of adultery, and the Trinitarian wording in 1 John 5:7 are familiar examples identified in modern translations. Canon is a separate question: Catholic, Orthodox, and Protestant churches do not include exactly the same Old Testament books.

وَأَنزَلْنَآ إِلَيْكَ ٱلْكِتَٰبَ بِٱلْحَقِّ مُصَدِّقًۭا لِّمَا بَيْنَ يَدَيْهِ مِنَ ٱلْكِتَٰبِ وَمُهَيْمِنًا عَلَيْهِ ۖ فَٱحْكُم بَيْنَهُم بِمَآ أَنزَلَ ٱللَّهُ ۖ وَلَا تَتَّبِعْ أَهْوَآءَهُمْ عَمَّا جَآءَكَ مِنَ ٱلْحَقِّ ۚ لِكُلٍّۢ جَعَلْنَا مِنكُمْ شِرْعَةًۭ وَمِنْهَاجًۭا ۚ وَلَوْ شَآءَ ٱللَّهُ لَجَعَلَكُمْ أُمَّةًۭ وَٰحِدَةًۭ وَلَٰكِن لِّيَبْلُوَكُمْ فِى مَآ ءَاتَىٰكُمْ ۖ فَٱسْتَبِقُوا۟ ٱلْخَيْرَٰتِ ۚ إِلَى ٱللَّهِ مَرْجِعُكُمْ جَمِيعًۭا فَيُنَبِّئُكُم بِمَا كُنتُمْ فِيهِ تَخْتَلِفُونَ
سورة المائدة · الآية ٤٨
And We have revealed to you, [O Muhammad], the Book in truth, confirming that which preceded it of the Scripture and as a criterion over it. So judge between them by what Allah has revealed and do not follow their inclinations away from what has come to you of the truth. To each of you We prescribed a law and a method. Had Allah willed, He would have made you one nation [united in religion], but [He intended] to test you in what He has given you; so race to [all that is] good. To Allah is your return all together, and He will [then] inform you concerning that over which you used to differ.

How the Biblical Texts Reached the Present
Key passage
Bible
Since many have undertaken to set in order a narrative concerning those matters which have been fulfilled among us, even as those who from the beginning were eyewitnesses and servants of the word delivered them to us, it seemed good to me also, having traced the course of all things accurately from the first, to write to you in order, most excellent Theophilus; that you might know the certainty concerning the things in which you were instructed.
Luke 1:1-4
Version: World English Bible

Two Transmission Stories, Side by Side
Language: the Quran is preserved and recited in its original Arabic, while the words of Jesus were spoken in Aramaic but preserved in Greek — with few exceptions, not available in his own tongue.
Timescale: Muslim tradition and the early manuscript record describe a complete text standardized within a generation of the Prophet Muhammad's death, while the New Testament canon took shape over centuries.
Mechanism: the Quran's transmission ran on two parallel tracks — mass memorization alongside written copies — each checking the other; the Bible's ran on hand copying alone, which is why variants accumulated and textual criticism became necessary.
Self-description: Luke's prologue describes research and compilation of handed-down reports; the Quran presents itself throughout as the direct speech of God to one messenger.

Common Misconceptions
"Muslims believe the Bible is worthless." Not so. The Quran calls the original Torah and Gospel guidance and light and calls Christians the People of the Gospel. The Islamic claim concerns transmission, not a denial that God spoke through Jesus.
"Textual variants mean nobody knows what the Bible says." Also not so. Mainstream textual critics hold that the vast majority of variants are minor and the general shape of the text is well established. The serious questions concern specific passages and wording — significant, but not a free-for-all.
"The books of the Bible were chosen at the Council of Nicaea." This story circulates in novels and internet memes, but historians of Christianity describe canon formation as a gradual process reflected in usage, debate, and later lists and councils. Repeating the Nicaea legend weakens any argument built on it.

Why the Quranic Criterion Matters
وَأَنزَلْنَآ إِلَيْكَ ٱلْكِتَٰبَ بِٱلْحَقِّ مُصَدِّقًۭا لِّمَا بَيْنَ يَدَيْهِ مِنَ ٱلْكِتَٰبِ وَمُهَيْمِنًا عَلَيْهِسورة المائدة · الآية ٤٨
'We have revealed to you the Book in truth, confirming what preceded it of the Scripture and as a criterion over it' (Quran 5:48). The transmission history explains why such a criterion is needed. Islam preserves respect for God's earlier messengers while locating final textual authority in the Quran.
summary
The Central Takeaway
notes
Frequently Asked Questions
A: No. Mainstream Christian scholarship agrees that Jesus left no writings. The Gospels were written about him, in Greek, in the decades after his ministry — a process Luke describes in his prologue.
Q: Do Muslims believe the Bible is completely corrupted?
A: No. The Quran affirms the original Torah and Gospel as guidance and light, and classical scholars differed over whether the distortion it warns of affected mainly the text or its interpretation. Today's Bible is seen as containing truth alongside material shaped by long human transmission.
Q: What language did Jesus speak, and why does it matter?
A: Historians broadly agree Jesus taught in Aramaic, while the New Testament was composed in Greek. With few exceptions, his words reach us in translation — a fact acknowledged in standard Christian scholarship.
Q: Who decided which books belong in the Bible?
A: No single meeting decided it. Books circulated and were debated for generations; the earliest surviving exact list of today's twenty-seven New Testament books comes from Athanasius in the later fourth century, and Christian communions still differ over the Old Testament canon.
Q: Is textual criticism an attack on Christianity?
A: No. It is a discipline built largely by Christian scholars seeking the earliest recoverable wording of the Bible. The manuscript footnotes in modern Christian Bibles are the fruit of that work.
