Who Wrote the Bible

We now come to one of the most fascinating and delicate questions in the entire course. Who actually wrote the Bible? And I want to warn you gently at the start. This is a unit where the answer many of us grew up with, and the answer most scholars give, have drifted a long way apart.

My job here is to lay both out fairly, to help you understand why thoughtful people land where they do, and to do it without fear. Remember the spirit of this whole course. Curiosity is not a betrayal. It is how the most serious readers have always approached these texts.

Let me start with the traditional answer, because it deserves respect and because it is where the tradition itself began.

For most of history, communities of faith attached specific names to the books of the Bible. Moses is said to have written the first five books of the Torah. King David was credited with the Psalms, or at least most of them. King Solomon was tied to the wisdom books, including Proverbs, Ecclesiastes, and the Song of Songs. The prophets wrote the books that bear their names.

In the New Testament, the four Gospels were attributed to Matthew, Mark, Luke, and John, and the letters were signed by Paul, Peter, James, John, and Jude. This traditional map of authorship is ancient; it is deeply woven into how the books have been read and loved, and it carries real weight simply because it is old and close to the source.

Now let me give you the scholarly answer, the mainstream consensus that developed over the last few centuries as people began to study these texts with new tools and new questions.

That answer is more complicated, and it turns on a single big idea. Many of the biblical books appear to be the product of a long process rather than a single sitting. They show signs of multiple hands, combined sources, later editing, and growth over time.

Scholars came to this not out of hostility but out of close reading. They noticed things in the text itself that were hard to explain if a single author wrote each book straight through.

Let me give you one clear example to make this concrete, and we will develop it more as we move on.

Tradition says Moses wrote the entire Torah, including the book of Deuteronomy. Yet the end of Deuteronomy describes Moses’ death and burial, and notes that no one knows the location of his grave “to this day.”

Readers noticed long ago that it is difficult for a man to write the account of his own death and burial, and to add that his grave remained unknown for a long time afterward. Something as simple and honest as that observation is the kind of thing that started people asking whether the picture might be more complicated than a single author from start to finish.

This line of questioning is not a modern attack on faith. Even ancient and medieval readers noticed puzzles like this and wondered about them.

I want to introduce a key idea here that will carry through the rest of the unit: the concept of composition as a process.

In the ancient world, texts often grew. A core of material might be spoken, then written, then copied, then supplemented, then edited, then combined with other material, then edited again, across generations. A book could carry a great name at its head, honoring a founding figure or a tradition traced back to that figure, while actually reaching its final form through many hands over a long time.

To ancient people, this was not dishonesty. Attaching a revered name to a work, or writing in the spirit and tradition of a great teacher, was a recognized and honorable practice. We will meet that practice again when we get to the letters of the New Testament.

So we have two honest answers on the table.

The traditional answer gives us named individuals and single authors, a picture that is ancient and beloved. The scholarly answer gives us a longer process of sources, authors, and editors, a picture built from close attention to the texture of the texts themselves.

For the rest of this unit, I want to walk you through the two most famous places where this question gets worked out, the Torah in the Old Testament and the Gospels in the New. Hold both answers in your mind as we go, and let yourself be curious rather than anxious. We are learning the shape of a real and serious conversation.

Let me take you into the single most famous example of the scholarly view of biblical composition, the study of how the Torah came to be. This is the standard model taught in introductory courses across the world, so I want you to understand it clearly, and I want you to understand why scholars proposed it in the first place.

Let’s begin with what careful readers noticed in the text. When you read the Torah closely, you begin to see patterns that are hard to explain if a single author wrote it all in one voice.

There are places where the same story seems to be told twice, with differences between the two tellings. There are two accounts of creation at the very beginning of Genesis, side by side, with different emphases, a different order of events, and even a different favored name for God. The flood story reads as though two versions have been woven together, which is why the number of animals and the length of the flood seem to be described in more than one way. The same kinds of doubling and difference appear elsewhere.

Readers also noticed that the name used for God shifts back and forth in a patterned way. In some passages God is called by the personal name often rendered as Yahweh in scholarship. In other passages God is referred to with the more general term often rendered as Elohim, meaning God.

Alongside these shifts came differences in vocabulary, in style, and in the concerns of different sections, with some material intensely focused on priests, sacrifice, and ritual detail, and other material telling vivid, earthy stories.

Out of observations like these grew the model known as the Documentary Hypothesis. In its classic form, it proposes that the Torah was woven together from several originally separate sources, each with its own style, vocabulary, and theological emphasis, and that these were combined and edited over a long period.

The four traditional sources are usually labeled with the letters J, E, D, and P. The J source favors the personal divine name and tells vivid, human stories. The E source tends to use the more general term for God and has its own flavor. The D source is associated especially with the book of Deuteronomy and its distinctive voice and concerns. The P source is the priestly material, focused on order, genealogy, ritual, and worship, and often credited with the stately first creation account.

In this model, editors, sometimes called redactors, wove these sources together into the Torah we now have.

I want to be careful and fair here, so let me say several things clearly. First, this is a hypothesis, a scholarly reconstruction, and the details are debated even among specialists. The neat four-source picture has been challenged, revised, and complicated in many ways over the years, and scholars argue vigorously about the number of sources, their dates, and how they came together.

What commands broad consensus is the underlying idea that the Torah is a composite work that grew over time through multiple hands, rather than a single document written straight through by one person. The exact recipe is disputed. But the fact that there was a recipe is widely accepted in the scholarly world.

Second, I want to name honestly that many people of faith find this model troubling when they first meet it, and others find that it enriches their reading. Seeing the Torah as a conversation across generations, a treasury into which many faithful hands poured their understanding of God, can be its own kind of wonder.

You do not have to resolve all of that today. This is an introductory course, and my aim is that you understand the model, understand why it exists, and understand that it is the mainstream scholarly account. We will return to the deeper questions later, as we always promise to do.

Third, notice how this connects to what we learned in earlier units. Back in Unit 2, we saw that arrangement is interpretation. Here we see that composition itself was a process of gathering and shaping.

The people who produced the Torah were doing something creative and theological with inherited material, and the seams that scholars point to are, in a sense, the fingerprints of that long and reverent labor.

Whatever you eventually conclude about the model, learning to notice those seams will make you a sharper and more attentive reader of the text.

Now let me carry the same question into the New Testament, into the four Gospels, where scholars have wrestled with a puzzle every bit as famous as the one in the Torah. It even has a name that sounds grander than it is. It is called the Synoptic Problem.

Let’s begin with a simple observation that anyone can make with a simple reading. Three of the four Gospels, Matthew, Mark, and Luke, are strikingly similar to one another.

They tell many of the same stories, in a broadly similar order, often in remarkably similar wording, sometimes matching word for word for long stretches. Because they can be lined up side by side and seen together, these three are called the Synoptic Gospels, from a Greek expression meaning to see together.

The fourth Gospel, John, stands notably apart, with its own distinctive style, its own selection of events, and its own long meditative speeches that sound quite different from the shorter, punchier sayings in the other three.

The Synoptic Problem is simply this. Why are Matthew, Mark, and Luke so similar, similar enough that one seems to be using another, and yet also different in revealing ways? When three documents agree word for word in long passages, the natural explanation is that they are somehow literarily related, that they share sources or that some copied from others. So how exactly are they connected?

The consensus among scholars is this. Mark was probably written first, the earliest of the Gospels, shorter and more compact. Matthew and Luke then appear to have used Mark as one of their sources, which explains why so much of Mark shows up in both of them, often in the same order and wording.

But Matthew and Luke also share a good deal of material, mostly sayings of Jesus, that are not found in Mark at all. To explain that shared non-Markan material, many scholars propose a lost source, a collection of sayings that both Matthew and Luke drew from independently.

Scholars call this hypothetical source Q, from the German word Quelle, which simply means source. Now, as a note, while much of what is thought to be from this Q source are sayings, there are also narrative portions.

On top of all of that, Matthew has material found only in Matthew, and Luke has material found only in Luke, which scholars attribute to their own special sources or traditions, which are often termed the M source and the L source, which just refers to that unique material.

This overall model, with Markan priority and a sayings source behind Matthew and Luke, is the most widely held solution, though like the Documentary Hypothesis, it is debated, and there are respected scholars who propose alternatives.

Now let me connect this to the larger point of the unit. Just as with the Torah, close reading reveals that the Gospels appear to be related through a process of shared sources and use of earlier material. The traditional picture gives us four independent eyewitnesses each writing his own account. The scholarly picture gives us a family of documents drawing on one another and on shared earlier traditions, both written and oral, in a community that was remembering, collecting, and shaping the story of Jesus over the decades after his life.

And notice, underneath all of this sits the oral tradition we mentioned back in Unit 1. Before any Gospel was written, the stories and sayings of Jesus circulated by word of mouth, told and retold in gatherings of the early movement. The written Gospels drew that living oral memory into fixed form.

I want to close this unit the way I opened it, with fairness and a calming reassurance. The differences among the Gospels, which the scholarly model helps explain, are sometimes treated as a threat. I would encourage you to see them first as a gift.

Four portraits of one figure give us more than a single flat photograph ever could. Matthew, Mark, Luke, and John each emphasize different things, shape their material toward different audiences, and bring out different facets of who they believed Jesus to be.

Understanding that they are related, and how, does not diminish them. It helps you read each one for its own distinctive voice, which is exactly the skill this whole course is trying to build.

So here is where this Unit 4 leaves us. There are two honest answers to the question of who wrote the Bible: the traditional answer of named single authors, ancient and beloved, and the scholarly answer of a longer process of sources, authors, and editors, built from close attention to the texts themselves.

The Torah is the great Old Testament example, where doubled stories, shifting names for God, and differences of style led scholars to the Documentary Hypothesis, a model of composite authorship that is debated in its details and broadly accepted in its core idea. And the Gospels are the great New Testament example, where the striking similarities among Matthew, Mark, and Luke led scholars to the theory of Markan priority and a shared sayings source, with John standing apart.

In both cases, close reading reveals a process of composition, and learning to see that process makes you a sharper reader.

That is a full and fair picture of the scholarly consensus on authorship. As we move forward, we will see exactly where the ground shifts a bit here, but for now, in our next unit, we will look at the Canon.
