Mind the gap

gap-4-cropped-400px“Mind the gap” is a warning phrase to take caution while crossing the spacial gap between a train doorway and the station platform. It’s used by many train and rapid transport systems. This gap is wider at stations with curved platforms, which increases the likelihood of passengers or luggage falling into the gap between the train and the platform.

In this blogpost we look at the temporal gaps between the events described in the New Testament and their communication to us today. We will see that as the memory gap (from an event to the original written account) is less than one generation and the copy gap (from the original written account to the oldest manuscript available today) is significantly less than for other ancient documents, we can trust the historical accuracy of the New Testament.

According to scholars, the New Testament was written between AD 50 and AD 95. And most of the events described in the New Testament occurred between 5 BC and AD 65. But why was the New Testament written so long after the events it describes (up to about 65 years)?

Oral communication

The major way in which events and ideas were communicated in the ancient world was through the spoken word. It was an oral society. Many people were illiterate and writing materials were scarce. There were few books (scrolls) and they were very expensive to produce. So information was passed on by word of mouth and oral accounts were valued above written accounts.

In oral communication, the accuracy of a message received by a listener depends on the reliability of the speaker (sender) and the reliability of the information that the speaker wants to communicate. A reliable speaker tells the truth (instead of lying) and the information they communicate is more reliable if the speaker has access to the original source of the information, such as eyewitnesses.

A message can become unreliable if it passes through many intermediate speakers between the original speaker and the final listener. This is demonstrated in the telephone (Chinese whispers) game in which one person whispers a message to the ear of the next person through a line of people until the last player announces the message to the entire group. What usually happens is that the statement announced by the last player differs significantly from that of the first player. Obviously, if a message (or story) has been retold by many people, some of it can change if people forget parts of what they are told.

But the telephone (Chinese whispers) game doesn’t apply to the New Testament, because the time period when it was communicated orally was less than 65 years, which is one lifetime, and not many lifetimes. I call the gap to the first written account of the New Testament “the memory gap”, because in this case the accuracy of the message is dependent on the accuracy of the messenger’s memory.

The memory gap

The New Testament was written by the apostles and their associates who were eyewitnesses to the events they described.  An apostle had accompanied Jesus Christ during His 3-year ministry (from His baptism to His ascension) and had been with the other apostles when Christ was resurrected (Acts 1:21-22). So they knew Jesus very well. This means they had accurate source of the information.

The memory gap for the gospels is 30-55 years. Mark, Matthew and Luke were probably written in the AD 60s, and John about AD 85. Some skeptics claim that, even with eyewitnesses, memory isn’t trustworthy over that period of time and that all kinds of things can contaminate the message. But the accuracy of the New testament message is enhanced by the fact that:
– there were multiple witnesses. According to the Old Testament, there must be at least two witnesses to establish the truth in a court case (Dt. 17:6; 19:15). For example, the accounts of four separate witnesses are given in the gospels (Matthew, Mark. Luke and John).
– there were 12 apostles who could oversee (control) the accuracy of the message. In this was there was corporate control of the message.
– When it’s all you’ve got, memory works well. For example, children have good memories for stories and the words and tunes of songs.
– Memory works well if you have a stake in what took place. The apostles had a stake in the gospel message because they had given up everything else to follow Jesus and most of them were martyred for their Christian faith.
– Corporate repetition is important for retaining stories and memories. The Christian message was repeated at weekly church gatherings.

It seems as though the message in the gospels was put in writing when the eyewitnesses were near the end of their lives. This enabled an accurate record to be passed on to subsequent generations. In a eulogy children recollect events that occurred in their family up to 50 years earlier. When they do this, the gist of their accounts will be the same, although they will recollect different details. Likewise, the gospels have the same core message, but each writer records different details. Most alleged contradictions in the gospels are just minor variations in the account. One eyewitness will include a piece of information, while another one will leave it out. If the accounts were identical, then there could have been collusion or plagiarism.

As Paul was in Jerusalem at the time of the crucifixion, he knew what had happened. So when he was writing letters between 50 and 66 AD (20 to 26 years later), he knew what he was writing about. Paul was probably converted a few years after the resurrection. He summarized the gospel as “For what I received I passed on to you as of first importance; Christ died for our sins according to the Scriptures, that He was buried, that He was raised on the third day according to the Scriptures” (1 Cor. 15:3-4NIV). He received this message orally from other apostles (Gal. 1:18-19) and passed it on to others. That’s an example of oral communication.

Oral transmission was done very carefully in ancient times. For example, Paul commended the Corinthians “for following the teachings I passed on to you” (1 Cor. 11:2NLT). These teachings were prescribed standards for Christian living.

The copy gap

The Bible is like a library (or anthology) – it’s a collection of books written by different authors. The text of each book was originally written on a manuscript (written be hand) called an “autograph”, which in the case of the Bible would have been a scroll. The memory gap is the period of time between the writing of the autograph and the events described in the autograph.

We don’t have the autograph (original manuscript) of most ancient documents. Instead we have copies that were made at a later time. Textural critics use the available copies to reconstruct the original autograph. I will refer to the time gap between a copy and the autograph, as the “copy gap”. Obviously, other things being equal, a longer copy gap provides more opportunity for copy errors to accumulate in the manuscript.

Ancient texts were written on papyrus scrolls which may have had a useful life of about 100 years (and up to 500 years in dry climates). However, some papyrus codices (books) from the third century AD survive today (such as the Chester Beatty Papyri written about AD 200). Between the late 3rd century and the 5th century AD, papyrus scrolls and codices were replaced by parchment pages in a codex (book). Parchment (or vellum; made from animal skins) was more durable and could have a lifetime of about 1,000 years. For example, marginal notes in the Codex Sinaiticus indicate that it was still being used by scholars about 300 years after it was written.

codex-vaticanus-2-400pxAccording to classical scholars, the oldest surviving complete copies of single New Testament books were written around AD 200, and the oldest surviving (nearly) complete copy of the New Testament, was written about AD 350 (see below). And the oldest surviving fragments of manuscripts of the New Testament were written in the second century AD (such as the John Rylands Papyrus written about AD 125). The fragments and books could be 1st and 2nd generation copies of the autograph, while the whole New Testament (copied in the mid 4th century AD) could be a 2nd or 3rd generation copy of the autographs. It should be understood that “complete manuscript” when used by a textual critic does not necessarily mean 100% of it has survived. “Complete” is a technical term meaning that the manuscript has the beginning and end of the book in question. For example, a “complete copy of John” would be required to have John 1:1 and John 21:25 and substantial portions of those verses between.

It’s instructive to look at the “copy gap” (between the original autograph and the oldest complete manuscript) for other historical documents. The copy gap is about:
– 1,400 years for the Histories of Herodotus (written in the 5th century BC),
– 800 years for the works of Josephus in their original language of Greek (written about AD 90),
– 1,000 years for the Annals of Tacitus (written about AD 115),
– 750 years for the letters of Pliny the Younger (written AD 112),
– 700 years for the “The Twelve Caesars” by Suetonius (written AD 120).
It has been stated that the copy gap (for the oldest complete manuscript) for most non-biblical classical sources is about 700-1400 years.

On the other hand, for the New Testament, the copy gap is about 300 years – Codex Vaticanus was written in about 325-350 AD and Codex Sinaiticus in about 330-360 AD. So the gap is significantly shorter for the New Testament. A longer gap means more copies of copies, which means more potential for copy errors to appear in the text. So the version of the New Testament we have today should be a more accurate copy of the original than is the case for most other ancient historical documents.

The scholar Sir Frederic Kenyon concluded, “The interval then between the data of original composition and the earliest extant (complete) evidence becomes so small to be in fact negligible, and the last foundation for any doubt that the Scripture have come down to us substantially as they were written has now been removed. Both the authenticity and the general integrity of the books of the New Testament may be regarded as finally established.”


An investigation of the gaps between the events described in the New Testament and their communication to us today shows that as the memory gap (from an event to the original written account) is less than one generation and the copy gap (from the original written account to the oldest complete manuscript available today) is significantly less than for other ancient documents, we can trust the historical accuracy of the New Testament.

Appendix: Dating the New Testament

We can infer that most of the NT was written before AD 70, because there is no mention of the invasion of Jerusalem by the Romans and the destruction of the Jewish temple. This event was prophesied in Matthew, Mark and Luke. So these gospels were written before AD 70.

Also, the martyrdoms of James in 62 AD, Paul in 64 AD, and Peter in 65 AD, which would have had a significant impact on the Christian community aren’t mentioned in the New Testament. So Acts was written before 64 AD, and Luke was written before Acts (Acts 1:1-2). This is consistent with Paul quoting from Luke in 1 Timothy (Lk. 10:7; 1 Tim. 5:18).

Most scholars agree that John was written after Matthew, Mark and Luke because it seems to build on and supplement these. The fact that the destruction of Jerusalem is not mentioned in John may be because the book was written 15-20 years later, when the shock had worn off. Also, church fathers thought that John wrote Revelation in about AD 95 (during Domitian’s reign over the Roman Empire).
