Summary of Goodacre-Kloppenberg about Q

In February 2026 at BSA, Mark Goodacre and John Kloppenberg presented opposing lectures about whether or not Q existed. A member of BSA offered a summary of their positions and Goodacre said the summary was better than he could have done. The summary is pasted below. Other members thought the summary was prepared with an AI. Goodacre thought so as well, but liked it. As Mark thought it was a good summary, it is pasted below. Formatting is mine.

Did Q Really Exist? A Scholarly Debate Over Ancient Texts

This exchange between two prominent New Testament scholars raises one of the most significant questions in Synoptic studies: Was there a lost sayings source called Q, or did Luke directly use Matthew?

Team Q: John Kloppenborg’s Position

The Case: Matthew and Luke independently used Mark and a second written source (Q) containing sayings of Jesus.

Key Arguments:

1. The Reorganization Problem
   Matthew and Luke often place shared sayings in very different locations within their respective narrative frameworks. If Luke copied from Matthew, why would he systematically rearrange large blocks of teaching material?
2. The Sermon Example
   Matthew presents the Sermon on the Mount (Matthew 5–7), while Luke presents similar material in the Sermon on the Plain (Luke 6:17–49). The teachings overlap substantially, but the narrative settings and structural contexts differ.
3. Close Verbal Agreement
   In passages absent from Mark (the so-called “double tradition”), Matthew and Luke sometimes agree in wording at a level suggesting a shared written source rather than independent oral transmission.

Why Q Is Proposed?

If Luke used Matthew directly, one might expect more consistent agreement in sequence and structure. The significant divergence in arrangement suggests, in this view, that both evangelists drew independently from a sayings collection.

Team No-Q: Mark Goodacre’s Position

The Case: Luke used both Mark and Matthew. Q is unnecessary as a hypothetical document.

Key Arguments:

1. Luke’s Literary Strategy
   Luke reshapes Mark into a more continuous narrative and relocates Matthew’s teaching blocks to serve his own compositional goals. Rearrangement is evidence of redactional creativity, not proof of a lost source.
2. The Journey Motif
   Luke structures much of his Gospel around Jesus’s journey to Jerusalem (Luke 9:51–19:27). This theological and narrative framework naturally requires the redistribution of teaching material.
3. Patristic Silence
   No extant early church writer explicitly mentions a document resembling Q. Ancient sources refer to Matthew and Mark, but never to a separate sayings gospel used by both Matthew and Luke.
4. Parsimony (Occam’s Razor)
   If Luke’s use of Matthew accounts for the data, introducing a lost document becomes methodologically unnecessary.

Why the No-Q Hypothesis Is Proposed

Luke may be understood as a deliberate literary author who freely adapts and reorganizes sources for theological and narrative purposes rather than preserving their structural sequence.

The Core Disagreement

Kloppenborg’s question:
How could two independent authors using the same source arrange it so differently without direct literary dependence?

Goodacre’s response:
Ancient authors were capable of substantial restructuring. Luke’s redactional freedom explains the divergences without positing a hypothetical source.

Underlying Issue

The debate turns on assumptions about ancient compositional practices:

• Were ancient writers generally conservative in preserving structure?
• Or were they creative redactors who freely reorganized inherited material?

Points of Agreement

• Mark is generally regarded as the earliest Gospel.
• Matthew and Luke both use Mark.
• Matthew and Luke share additional material not found in Mark.

Point of Disagreement – Whether that shared non-Markan material derives from:

• A lost sayings source (Q), or
• Luke’s direct use of Matthew.

What Is at Stake? The question affects broader issues in biblical scholarship:

• Models of literary dependence among the Synoptic Gospels
• The plausibility of reconstructing lost written sources
• Assumptions about ancient historiography and compositional technique
