Comparative Theology · Additions & Interpolations
Timeline: When Each Addition Entered the Text
Handle with care. Do not present the timeline as evidence of deliberate corruption at every stage. Most changes were unintentional or well-meant; the argument is about preservation, not malice.
In short
- 1.2nd-3rd century: harmonisations between Gospels, explanatory glosses like John 5:4
- 2.4th-5th century: the long ending of Mark spreads; the Comma appears in Latin
- 3.1516-1611: Erasmus, the Textus Receptus and the KJV fix additions in print
- 4.1881 onward: critical editions remove them again
The claim being examined
Interpolations are not a single event. They accumulated across more than a thousand years of hand copying, and each one can be dated.
The Islamic position
Islam's claim is about transmission over time, not about a single act of forgery. A timeline is the most accurate way to present that claim.
Analysis
The earliest period of copying was the least controlled — professional scriptoria came later, and the second-century copies were made by non-professionals within local communities. This is when most harmonisations and glosses entered. From the fourth century, standardised Byzantine texts spread these readings widely. The invention of printing froze one late form of that tradition into the Textus Receptus, which the King James translators used. Nineteenth-century access to Sinaiticus and Vaticanus, and twentieth-century papyrus discoveries, allowed the additions to be identified and removed. The scholarship that exposes the additions is itself Christian scholarship.
Side by side
| 2nd-3rd century | John 5:4, harmonisations | Glosses and cross-Gospel harmonisations enter during uncontrolled early copying. |
|---|---|---|
| 4th-5th century | Mark 16:9-20, Comma (Latin) | Longer endings spread; the Trinitarian formula appears in Latin only. |
| 1516-1611 | Erasmus → Textus Receptus → KJV | Late readings fixed in print and inherited by English Bibles. |
| 1881-present | Critical editions | Earlier manuscripts recovered; additions bracketed, footnoted or removed. |
From the Qur'an
Qur'an 15:9
إِنَّا نَحْنُ نَزَّلْنَا الذِّكْرَ وَإِنَّا لَهُ لَحَافِظُونَ
Indeed, We sent down the Reminder, and indeed We are its guardian.
