Basics of Textual Criticism

26 May 2026

If you look at the end of the Gospel of Mark in any Bible that has some footnotes, you’ll notice something odd: there will be a note about 16:9-20. Depending on which translation you’re looking at, it will either say that verses 9-20 are part of the original text, but some manuscripts don’t have it, or it will say that verses 9-20 are not original, but some manuscripts have them. How do we tell which is right? And why do scholars differ on something like this?

First the good news: we have the original text of the New Testament established with a very high degree of confidence. The amount of manuscript evidence is extraordinary; other than the Hebrew Bible, no other ancient document even comes close. To give you an idea, we have around 25,000 total manuscript witnesses for the New Testament. The next most common ancient document is Homer’s Iliad, with under 1800. From there, it drops sharply: Plato’s works (about 250), Sophocles’ tragedies (under 200), Herodotus (just over 100), Aristotle (around 50), and so on.

In fact, the plethora of evidence is both a problem we have to navigate, and a source of solutions. That 25,000 manuscripts breaks down into 5,800 Greek manuscripts, plus the translations–10,000 in Latin and another 9,000+ in other languages. Every single one of them was hand-copied, and so of course there are scribal mistakes. Because we have so much evidence, most of those mistakes are pretty obvious. If one manuscript leaves out a phrase, but all the rest have it, we can be pretty sure which reading is right.

Most of the variations are nowhere near as consequential as the ending of Mark. For example, the single most common variation is a feature called the “movable nu.” It’s the Greek letter “n”, sometimes added to the end of a word that ends in a vowel. English does this too, with the indefinite article: a vs. an. We say “a house,” but “an apple,” because the latter sounds better to us. Greek has that same feature, but uses it with more words. That’s the movable nu. It doesn’t change the meaning of the word at all; it’s purely there for the sound. That is the single most common textual variant in the Greek New Testament, and it makes no difference at all.

Even most of the variants that are a different word usually don’t change the meaning of the sentence they’re in. What those variations can do, though, is help us establish how different manuscripts are related to each other. Two manuscripts that exhibit the same pattern of variants are very likely to be related to one another somehow. This is now we identify families and subfamilies of manuscripts. We’ll come back to that in a moment.

Now the bad news: there are a small minority of variants that do make a difference, for instance the question of whether Mark 16 ends after verse 8 or continues through verse 20. The art and science of discerning which reading best represents the original text is called textual criticism, and it’s not an easy pursuit. My goal here is to acquaint you with the basics of the discipline, and help you understand why there are different schools of thought within it.

Textual criticism uses a set of criteria to try to sift the available evidence and reconstruct the original text. Along the way, we’ve developed a series of guidelines that help. For example, given two different readings, we generally prefer the shorter one, because we find that scribes tend to err by adding words more often than deleting them. We prefer the harder reading, because scribes tend to simplify the text, not complicate it. We prefer the reading that reasonably accounts for the other readings. We prefer the reading from the best quality of manuscripts, not just the reading we find in the most manuscripts. And so on. Of course this is an art as well as a science, and scholars differ in how they apply these principles to particular cases; hence the differences.

Now obviously none of those guidelines would matter if we could hop into a time machine and go take pictures of the original scroll of Mark’s gospel, straight from his hand, with the ink still wet. If we had a photograph of the ending of Mark’s original draft, then it wouldn’t matter if it was shorter or longer, harder or easier, etc. But we don’t have that, and we’re using these guidelines to try to figure it out from the evidence we do have.

Failing the original, we’re playing a written version of the Telephone Game: we’re looking at copies of copies of copies. What we’re trying to do is establish which copies are the best witnesses to the original. Again, remember the good news: we have a ton of evidence, and overwhelmingly, the manuscripts we have agree with one another.

But what about where they don’t? Of course, if one single manuscript has a reading that none of the other 5,800 manuscripts have, we can pretty confidently chalk it up to scribal error. That’s not really a hard problem. The harder problem is when we have a bunch of manuscripts that have one reading, and a bunch more that read differently, as we do at the ending of Mark.

When you look at a series of such differences, you quickly realize that what you’re seeing is “families” of manuscripts. So now the question becomes, which family or families are more reliable? How do we know?

Remember, we’re playing a giant, centuries-spanning game of Telephone. So all other things being equal, the older a family is, the better–it’s fewer generations away from the source, and therefore fewer opportunities for errors to creep in. If it were that simple, we’d all just take the oldest manuscripts we could get, and call it a day. But age is not the only criterion that matters.

We also want widespread evidence. If we have a family of manuscripts that all come from one specific place, that doesn’t tell us a lot about what they were reading in other places. The manuscripts copied in that one place might have some idiosyncrasies that aren’t representative of everywhere else. So ideally, we want manuscripts from many places that all agree with one another.

We also want the most careful copying we can get, and not every family shows equal care. How can we tell? By tracking how much variance there is within the family. Families where the manuscripts disagree with one another a lot (relatively) show that the scribes weren’t as careful in their copying. Families where the manuscripts disagree with one another very little show that the scribes were very careful.

So putting it all together, what we want is the oldest family, the most geographically widespread family, and the family that shows the least internal disagreement. If we could get all of those in one manuscript family, there wouldn’t be much debate about textual criticism. Alas, that option is not on the menu.

The oldest manuscripts we have all come from Egypt, because papyrus was by far the most common writing material throughout the Roman world, and papyrus doesn’t tolerate moisture well, especially over the long term. It has a tendency to just fall apart if it gets wet at all. So the Sahara desert did us a huge favor by preserving manuscripts that couldn’t have survived anywhere else. These are collectively known as the Alexandrian family of manuscripts. Unfortunately, the Alexandrian manuscripts also exhibit a relatively high amount of internal disagreement within the family.

The other major family of manuscripts is known as the Majority Text. (The use of “majority” here is not tactical; even its ardent opponents like Kurt Aland use the term, because it clearly does encompass the majority of Greek manuscripts.) The Majority family is younger than the Alexandrian, but it is geographically widespread and exhibits far less internal disagreement than the Alexandrian; it gives evidence of more careful copying. In fact, there’s so little disagreement within the family, and it’s so widespread, that Wescott and Hort (early advocates of the Alexandrian texts) felt the need to literally invent a historical event to account for it. They suggested that Lucian of Antioch revised the New Testament text in the early 4th century and forced everyone to accept his version — a ridiculous slander for which there has never been a shred of historical evidence. That idiocy has long since been debunked , and the better explanation is as simple as it is disagreeable to Wescott and Hort’s thesis: the Antiochenes were careful about their copying, and the Alexandrians were notably sloppier. (Just like the Antiochenes were more careful with their hermeneutics, and the Alexandrians more sloppy — but that’s another post.)

Scholars who prefer the Alexandrian family are betting that the older manuscripts of Egypt are a representative sample of the whole Roman world. They don’t have any evidence that’s the case (since we don’t have manuscripts that old from anywhere but Egypt), but that’s the bet they’re making. The hard pill they have to swallow is that the far majority of manuscripts, and the more carefully copied family of manuscripts, disagree with them.

Scholars that prefer the Majority text are making a different bet: that the more carefully copied and more widespread family of manuscripts are better evidence, even though the copies we have are younger. They are betting that the Alexandrian family is a regional text that existed because of sloppier copying practices, and the witnesses we find throughout the Mediterranean world (although they’re younger) are representative of what was available in those places earlier on. The hard pill they have to swallow is that they have no early manuscript evidence, because there aren’t any manuscripts that old in the rest of the Mediterranean world.

So you can pick older, but local and sloppier, or you can pick younger, but more widespread and more careful. Not surprisingly, people disagree about which option is better. There’s also a school of thought that you should take it on a case-by-case basis using internal evidence. Dangerous ground, that, since the operative definition of “internal evidence” is sometimes “what I think it oughta say.” But there’s a case to be made for it nonetheless.


De-Christianisation as Apologetics

20 May 2025

Rough way to find out, but here we go…

Watch the whole interview here. If you’re not familiar with her work, Louise Perry is the author of The Case Against the Sexual Revolution and one of the more incisive commentators of our day when it comes to sex and gender issues. In this interview, she talks about her journey and why she intends to raise her children Christian even though she’s not a Christian (yet).


Defining Truth

20 September 2009

The Truth Project takes as its definition of truth a quote from Noah Webster’s 1824 dictionary:

that which is in conformity to fact or reality

(Missed a heck of a trick by not sticking with John 14:6, but anyway…)

Returning to the Webster definition for the moment, the advantage is that it ties “truth,” “fact” and “reality” together.  This keeps someone from playing silly word-games where they talk about how truth is different from fact, and so on.  But when you insist on the Webster definition as a way to say that there’s such a thing as truth, and that it’s not relative, a savvy unbeliever will ask you to define “reality,” and before you know it, you’re mired in a debate about post-foundationalism, postmodern epistemology, social construction of reality, reliability of sense perception, optical illusions, misperceptions, and the like.  Messy.

Navigable, if you keep your head, remain humble, ask for clarification, and keep your eyes firmly fixed on Scripture, but very, very messy.

Tactically, there’s a better option. The Webster definition has the same essential meaning as a famous definition of “truth” given in one-syllable words (Socrates by way of Plato by way of C. S. Lewis, if I remember correctly):

He who says of what is, that it is, or of what is not, that it is not, tells the truth;

he who says of what is not, that it is, or of what is, that it is not, lies.

Now, because it has the same sense as the Webster definition, it’s vulnerable to the same sort of attack.  It’s just that since it doesn’t have the words “fact” or “reality” in it, he can’t ask you to define “fact” or “reality.”  Instead, the attack comes at the word “is.”

That’s right.  Your savvy interlocutor is going to have to ask you to define “is.”

And thanks to a certain former president, you get to say, “So it all depends on what the definition of ‘is’ is?  Really?”

That presidential statement has become, in our culture, a universal symbol for a liar playing stupid word games in order to avoid facing the obvious truth.  Milk it for everything it’s worth: “Answer a fool according to his folly, lest he be wise in his own conceit.”

News: Devotional Apologetics Online Seminar

12 October 2008

Apologetics is devotional, worshipful, and radically sanctifying…

…if it’s done properly.

Most Christians find that statement surprising.  Christians tend to respond to challenges to their faith by succumbing to one of two temptations.  On the one hand, the gung-ho debaters among us seize on the opportunity to score a few points on the forces of unbelief, and there are some serious temptations that go with that.  These folks, however, are only a tiny minority — and even they wouldn’t normally describe their experience as devotional and worshipful.

Then there’s everyone else — those who dread a serious challenge to their faith.  These are the people who get past the local freethinkers’ society table at the county fair by walking fast and not making eye contact, who respond to Jehovah’s Witnesses at the door by pretending that nobody’s home, who retreat from serious discussion with a skeptical friend by saying “I don’t know how I know it’s true — I Read the rest of this entry »


Two Books for a More Robust Bibliology

7 September 2008

“The site is not the source.” In bodywork, this maxim means that where the client feels pain is probably not the location of the real problem. Back pain can be the result of an ankle injury that didn’t heal completely; pain in the elbow can come from chronic tension in the neck, and so on.

The same holds true in theology. We feel the pinch in a lot of areas lately, and we usually set about defending at the site — the place where we feel the pinch.

The Bible suggests a different approach. “Man shall not live by bread alone, but by every word that proceeds from the mouth of God.” If we’re hungry, eating is not the only, or even the first, solution. The first thing is to go back to God’s Word.

The Battle Belongs to the Lord by K. Scott Oliphint makes this line of thought explicit in the field of apologetics. When pressed by various Read the rest of this entry »


Further News on the Apologetics Seminar

15 July 2008

It seemed appropriate to add a little more about the nature of my approach to apologetics, since what we’ll be doing is a little uncommon.

My basic orientation on apologetics is that it’s all of a piece with theology, evangelism, and culture. Having a gleefully Christian take on everything from anchovy migration patterns to Zulu cooking is an integral part of defending the faith, not to mention a very persuasive witness in itself. Of course, no one person can know about everything, so learning how to construct a Christian approach to the subject at hand is terribly important.

Apologetics Seminar

13 July 2008

A local church here has agreed to host a four-week series on apologetics, taught by yours truly and starting this coming Friday (18 July), 7-9 pm in Orange, CA. Sorry about the short notice; we just got the details nailed down Friday night.

I’m titling the series “Biblical Apologetics for Busy Believers.” A rough, and tentative, outline follows:

Session 1: Start with God (Genesis 1-3) — All thinking must start with God, and the nature of God’s claims is such that no one can be neutral. A Christian must always begin with this understanding; to fail to start everything with God’s revelation is to make the same mistake that Eve made in the Garden of Eden. (As an example, we’ll consider a Christian response to the claim that there’s no good historical evidence for Jesus.)

Session 2: Without Excuse (Romans 1) — Unbelief has no excuse whatsoever; the unbeliever really does know the Christian God. To the extent that he refuses to acknowledge the triune God of the Bible, his Read the rest of this entry »


Basic Resources for Apologetics: An Overview

13 July 2008

If you’re looking for encyclopedic, facts-and-figures resources, there’s a ton of them on the market, and Josh McDowell’s material is still some of the best. A recent publication, Evidence for Christianity, combines and updates the evidential material from a number of previous works, and that’s the one I’d recommend, if you haven’t already got a few of McDowell’s works on the shelf.

Facts and figures are important, but in this post I want to address resources for how you use them. McDowell was never the best source for this — he’s more of the “make a bigger pile” school of thought. Until very recently, all the really good basic instruction on how to use the facts was on audio, but there wasn’t a book that did the job effectively and accessibly. Gary DeMar at American Vision has changed all that by transcribing and editing a series of talks Greg Bahnsen did for high school and college students back in the early nineties. The resulting book, Pushing the Antithesis: The Apologetic Methodology of Greg L. Bahnsen, is a gem. It’s accessible, relatively simple, and it has study questions at the end of each chapter. It’s also a little spendy, but it’s worth it. Bahnsen’s other basic book, Always Ready: Directions for Defending the Faith, is cheaper, but it’s a set of course syllabi edited together by Robert Booth. It’s much denser, and because the material was designed to be accompanied by live instruction, it’s much harder to plow through without help. Thanks to Pushing the Antithesis, the necessary help is now available in print.

The Weight of Glory

6 June 2008

The load, or weight, or burden of my neighbor’s glory should be laid on my back, a load so heavy that only humility can carry it, and the backs of the proud will be broken. It is a serious thing…to remember that the dullest and most uninteresting person you can talk to may one day be a creature which, if you saw it now, you would be strongly tempted to worship, or else a horror and a corruption such as you now meet, if at all, only in a nightmare. All day long we are, in some degree, helping each other to one or the other of these destinations. It is in the light of these overwhelming possibilities, it is with the awe and circumspection proper to them, that we should conduct all our dealings with one another, all friendships, all loves, all play, all politics. There are no ordinary people. You have never talked to a mere mortal. Nations, cultures, arts, civilisations — these are mortal, and their life is to ours as the life of a gnat. But it is immortals whom we joke with, work with, marry, snub, and exploit — immortal horrors or everlasting splendours. Read the rest of this entry »
