Source Criticism

The Core Assumption

Meaning lives in the earlier sources a composite text combines, so the text's history of composition must be uncovered.

The Four Assumptions

Where meaning lives

Meaning lives partly in the history of the text's composition, so a passage is understood by tracing the sources it combines and their separate voices.

What the text is

The text is a composite document whose seams, duplications, and tensions preserve the history of its own making.

Who may interpret

The interpreter is the scholar trained to detect stylistic and theological variation and to test source hypotheses against the text.

What counts as a good reading

A source division is adequate when it consistently explains the text's duplications, vocabulary shifts, and theological tensions better than reading the book as a unity.

Genealogy

This method arose in the 19th c period (18th century origins, classic form in the late 19th century).

Key proponents: Julius Wellhausen, Karl Heinrich Graf, Hermann Gunkel, William Wrede.

Key texts: Prolegomena to the History of Ancient Israel by Julius Wellhausen; The Synoptic Problem by various, classic statement in the two-source hypothesis; The Formation of the Synoptic Gospels, discussions of Markan priority.

The Procedure

These are the same steps The Workshop will walk you through.

1. Notice the seams

   Mark duplications, contradictions, abrupt changes of vocabulary, and shifts of perspective in the passage.

   Why this step matters: Source criticism begins from observable features that unity alone cannot explain.

   How to do it: List each seam with its exact verse references before proposing any source.

   What goes wrong here: Calling every tension a source seam when a single author could produce it.

   You record: Seam list. Done well when: Each seam is a genuine textual feature, not an imported difficulty.

2. Test the divisions

   Try dividing the passage among candidate sources and check whether each part is internally consistent.

   Why this step matters: A source hypothesis earns assent by making each source read coherently on its own.

   How to do it: Track vocabulary, divine names, theology, and narrative details across the whole book, not one passage only.

   What goes wrong here: Dividing a text by one criterion, such as divine names, while ignoring the rest.

   You record: Proposed source division. Done well when: Each proposed source is consistent in style and content across its assigned parts.

3. Characterize each source

   Describe each source's distinctive vocabulary, theology, social setting, and interests.

   Why this step matters: A source is not a name but a profile that must be recognizable wherever it appears.

   How to do it: Distinguish firm characteristics from traits inferred from a single passage.

   What goes wrong here: Inventing a source's theology from the very passage being divided, then using it to prove the division.

   You record: Source profiles. Done well when: Each profile is supported by multiple passages assigned to that source.

4. Date and situate the sources

   Propose dates and settings for each source, and a sequence for their combination.

   Why this step matters: Source criticism aims at a history of the text's growth, not a static list of documents.

   How to do it: Use independent evidence, such as datable institutions and language, rather than the hypothesis itself.

   What goes wrong here: Dating a source by the theology one wishes to find at that period.

   You record: Composition history. Done well when: Each date is supported by evidence independent of the source division.

5. Read the composite

   State what the final composition achieves by combining these sources in this order.

   Why this step matters: The redactor's work is itself a theological act worth interpreting, not merely a problem to dissolve.

   How to do it: Note placements, framing, and juxtapositions that create meaning beyond any single source.

   What goes wrong here: Stopping at the division and never interpreting the book as it stands.

   You record: Reading of the composite text. Done well when: The reading addresses the final text as readers actually encounter it.

Inputs Required

• A biblical book or passage in a translation that preserves its seams
• A concordance and tools for vocabulary analysis
• Knowledge of the classic source hypotheses for the book in question

Outputs Produced

• A source division of the passage
• Profiles of the underlying sources
• A composition history for the book

Quality Criteria

Under this method, a good reading is one that meets these tests:

• Consistency of each proposed source across many passages
• Explanatory power over the observed seams
• Independence of the dating evidence
• Acknowledgment of the final text as an object of interpretation

Common Errors

• Over-dividing texts into fragments that explain nothing
• Treating hypothetical sources as discovered facts
• Ignoring the final composition once the sources are named

Strengths

• It explained otherwise inexplicable duplications, such as the two creation accounts and the two flood chronologies.
• It gave the Pentateuch and the Synoptic Gospels a testable history of composition.
• It opened the text to questions about the communities that produced its sources.

Weaknesses and Critics

• Its classic Pentateuchal hypothesis has been substantially revised, and its documentary sources are now disputed in detail.
• It fragments books whose unity later methods recover.
• Source boundaries often rest on cumulative, contestable judgments rather than decisive evidence.

John Van Seters: Van Seters argued that the documentary hypothesis misdates and mischaracterizes its sources, especially the Yahwist, and that the Pentateuch's composition is better understood as a later literary process than a mosaic of independent documents. (Abraham in History and Tradition and Prologue to History, by John Van Seters)

Brevard Childs: Childs argued that source criticism's preoccupation with sources displaced the canonical text, which is the only text the community of faith actually reads and confesses. (Introduction to the Old Testament as Scripture by Brevard Childs)

Internal Schools

Classical documentary school: Wellhausen's school divides the Pentateuch into J, E, D, and P, dated in that broad sequence and tied to stages of Israel's religion.

Supplementary and fragmentary revisions: Later scholars, including Van Seters and Rendtorff, replace the documentary model with later supplements and fragments added to a core narrative.

Exemplar Readings

Wellhausen on the flood (Genesis 6-9): Wellhausen separated the flood narrative into a Priestly account, with its measured chronology and dates, and a Yahwist account, with its seven pairs of clean animals and narrative vividness, explaining the double chronology and duplicate commands.

The two-source hypothesis on Matthew and Luke (Matthew and Luke against Mark): Source criticism reads Matthew and Luke as each combining Mark with a sayings source, Q, explaining their extensive verbatim agreement with Mark and their shared non-Markan sayings.

What This Method Cannot Do

Site Stance

The site has not yet assigned its stance on this method. The stance assignments wait on the named reviewers, the same naming the Christian Assessment verdicts wait on. The method stands here in full in the meantime: a stance discloses the site's judgment, and it never filters what a reader may read or run. The stance values and their criteria stand on the criteria page.
