Concept
Synoptic Problem
Intro
Sponsored
Put Matthew, Mark, and Luke side by side and you notice something strange. They tell many of the same stories, often in the same order, and sometimes in almost identical wording. Other times they overlap with two of the three but not the third. And each of them has unique material the other two lack.
That pattern is what scholars call the synoptic problem. (Synoptic means "seen together," because you can read the three in parallel columns.) The question is: how did they end up so similar in places and so different in others? Did one copy from another? Did they share a written source nobody has? Did they all draw from a common oral tradition?
The most popular answer for the last 150 years is the Two-Source Hypothesis. It says Mark was first, and Matthew and Luke independently used Mark plus another lost written source nicknamed Q (from German Quelle, source). Q is supposed to be the bag of sayings Matthew and Luke share that are not in Mark, things like the Beatitudes and the Lord's Prayer.
There is no copy of Q. Nobody has ever found one. It is a hypothesis built from the overlap pattern. Some scholars accept it. Others propose alternatives: Luke used Matthew (the Farrer-Goodacre proposal), Matthew came first (Griesbach), or the relationship is more complex than any clean diagram.
This matters for apologetics because radical reconstructions of "the historical Jesus" often rest on slicing Q into early and late layers and treating only the early layer as authentic. That whole project depends on Q existing. If Q is shaky, the radical-Jesus project gets much shakier too.
Quick reply line: "The synoptic problem is real. The Two-Source Hypothesis is one solution. Q is a guess, not a manuscript. The radical-Jesus reconstructions built on Q layers are built on a building that may not exist."
In full
The literary-critical question of how Matthew, Mark, and Luke (the synoptic gospels, gospels that can be "seen together" in parallel columns) relate to one another. The question is forced by the data: the three gospels share substantial material in close verbal agreement, with characteristic patterns of agreement and disagreement that any model has to explain. The dominant scholarly answer for ~150 years has been the Two-Source Hypothesis, Mark was first, and Matthew and Luke independently used Mark plus a hypothetical sayings-source called Q (German Quelle = "source"). Q is the centerpiece of contemporary critical scholarship on the synoptics and the focal point of apologetic engagement, since "Q-stratified Jesus" reconstructions are the basis for many revisionist accounts of the historical Jesus.
This hub sets out the data, the major models, the case for and against Q, and the apologetic responses Christians should be ready to deploy.
The data to be explained
Synoptic material sorts into four categories:
| Category | Description | Approximate share |
|---|---|---|
| Triple tradition | Material in Matt + Mark + Luke (e.g., feeding the 5,000, baptism of Jesus, passion narrative) | ~50% of Mark; ~25% of Matt and Luke |
| Double tradition (Q) | Material in Matt + Luke but NOT Mark (Lord's Prayer, Beatitudes, Sermon on Mount/Plain, Baptist's preaching, temptation narrative, woes, Q apocalypse) | ~235 verses |
| Special M | Material unique to Matthew (genealogy, magi, Sermon on Mount additions, [[Matthew 25 | Matt 25]] parables, [[Matthew 28 |
| Special L | Material unique to Luke (Annunciation, Magnificat, Good Samaritan, Prodigal Son, Emmaus, [[Luke 1 | Luke 1]]-2 infancy material) |
The "agreements" are striking: Matt 3:7-10 and Luke 3:7-9 give John the Baptist's "brood of vipers" speech in 63 of 64 Greek words identical, despite both writing without Mark's version of this saying. Patterns like this constrain any model, there must be a literary-source relationship (oral tradition alone won't produce 63-of-64-word verbatim agreement).
The major models
1. Two-Source Hypothesis (mainstream)
Claim: Mark was first. Matthew and Luke independently used Mark + a hypothetical sayings source (Q) + their own special material (M and L).
Origin: developed in 19th-century German scholarship (Christian Hermann Weisse, 1838; H. J. Holtzmann, 1863); given canonical English-language statement by B. H. Streeter, The Four Gospels: A Study of Origins (1924), which expanded it to a "Four-Document Hypothesis" (Mark + Q + M + L).
Held by: the majority of academic NT scholars, John Kloppenborg (the leading living Q scholar), Christopher Tuckett, James Robinson, Bart Ehrman, Dale Allison, John Meier, James Dunn, N. T. Wright (with reservations).
Reasons to posit Q specifically:
- Verbatim Greek agreements between Matt and Luke in non-Markan material (the Baptist's preaching, Lord's Prayer, Q apocalypse) require a literary source, not just oral tradition.
- Matt and Luke do not appear to know each other's specifically Matthean / Lukan material (e.g., Luke seems unaware of Matthew's infancy narrative, magi, Matt 28 commission; Matt seems unaware of Luke's good Samaritan, prodigal son).
- The independent ordering of double-tradition material in Matt and Luke is hard to explain if one used the other; easier if both arranged Q according to their own redactional interests.
- "Doublets", sayings that appear twice in Matt or Luke (once from Mark, once from Q), suggest two independent sources.
2. Farrer-Goulder-Goodacre Hypothesis (the Q-skeptic alternative)
Claim: Mark was first. Matthew used Mark. Luke used Mark and Matthew. There is no Q.
Origin: Austin Farrer, "On Dispensing with Q" (in Studies in the Gospels, ed. D. E. Nineham, 1955); developed by Michael Goulder, Luke: A New Paradigm (1989); given the major contemporary defense by Mark Goodacre, The Case Against Q (2002) and The Synoptic Problem: A Way Through the Maze (2001). Sometimes called "Lukan posteriority."
Held by: a respected minority, Goodacre (Duke), the late Goulder, E. P. Sanders (sympathetic), Eric Eve, John Drury.
Their case:
- Q is unattested. No manuscript fragment, no patristic mention, no quotation. Streeter himself acknowledged the awkwardness. Every other ancient document widely used in the early church is attested either by manuscript or by external citation; Q is not.
- The "minor agreements" against Mark. Matt and Luke agree against Mark in many small details within the triple tradition (e.g., both say "who is it that struck you?" at Matt 26:68 / Luke 22:64, missing in Mark 14:65). The two-source hypothesis has to handle these as either coincidence, textual corruption, or "Mark-Q overlap" (a desperate move). Lukan-knowledge-of-Matthew explains them naturally.
- Editorial fatigue. Goodacre's signature argument: when Luke's redactional fingerprint appears at the start of a pericope but fades into Matthean phrasing partway through, this looks like a redactor tiring of his source, and Luke's source is therefore Matthew, not Q.
- Reconstruction circularity. "Q's order" is reconstructed by following Luke's order, on the assumption that Luke is more conservative with Q than Matt is. But this is circular: if you don't already accept Q, you have no reason to think Luke preserves Q's order. The Q-text in critical editions (Robinson-Hoffmann-Kloppenborg, The Critical Edition of Q, 2000) is essentially "what's left when you subtract Mark from Luke."
- No passion narrative. A sayings collection without a passion / resurrection narrative would be unique in the early Christian movement (the Gospel of Thomas is the closest analogue, but Thomas is later and gnostic). Streeter, Kloppenborg, and others answer that Q was a supplement to oral passion-tradition, but this concedes that Q was not a "complete" gospel and weakens the "Q gives us the real Jesus" reconstructions.
3. Other models
- Augustinian Hypothesis (Augustine, De Consensu Evangelistarum): Matthew first → Mark abridged Matt → Luke used both. Held by some traditional Catholic scholars and (in modified form) by C. S. Mann (Anchor Bible Mark, 1986).
- Griesbach / Two-Gospel Hypothesis (J. J. Griesbach, 1789; revived by William R. Farmer, The Synoptic Problem, 1964; defended today by David Peabody, Allan McNicol): Matthew first → Luke used Matt → Mark conflated both.
- Multi-Source Hypotheses (Pierson Parker, M.-É. Boismard), postulate multiple intersecting sources beyond the simple Q proposal.
- Oral tradition models (B. F. Westcott; recently James D. G. Dunn, Jesus Remembered, 2003): downplay literary dependence and emphasize stable oral-tradition transmission. Dunn doesn't deny Markan priority but treats some agreements as oral-tradition phenomena.
The genuine state of the field: Markan priority is near-consensus (~95%); Q is majority-but-not-consensus (~60-70%); the Farrer hypothesis is a significant minority view (~15-25%, growing); other models are marginal.
Q stratification, the apologetic flashpoint
The serious apologetic concern is not Q-as-a-document but the Crossan-Mack-Robinson reconstruction of "the historical Jesus" from a stratified Q.
The Kloppenborg stratification
John Kloppenborg, The Formation of Q (1987), proposed that Q itself shows literary strata:
- Q1, sapiential (wisdom) sayings: a sage's instructional material (Beatitudes, "love your enemies," "consider the lilies"). Hypothetically the earliest layer.
- Q2, prophetic / apocalyptic judgment material: woes against "this generation," "the day of the Son of Man." Layered onto Q1.
- Q3, biographical / temptation narrative framing: the Q temptation account (Luke 4:1-13 / Matt 4:1-11). The latest layer.
Kloppenborg himself was cautious about what stratification means, he held that literary layers don't necessarily map onto chronological development of the Jesus tradition.
The Crossan / Mack / Robinson overreach
John Dominic Crossan (The Historical Jesus, 1991), Burton Mack (The Lost Gospel: The Book of Q and Christian Origins, 1993), and to some extent James M. Robinson went further: they treated Q1 as the earliest historical layer of the Jesus tradition, and concluded that the earliest Jesus was a Cynic-style wisdom sage, non-apocalyptic, non-Messianic, non-divine, non-resurrected. Christianity-as-we-know-it (atoning death, bodily resurrection, divine Christ) is a later overlay of mythology onto a wisdom-teacher original.
This thesis became a centerpiece of the Jesus Seminar (Robert Funk, Crossan, Marcus Borg) and is the most popularly disseminated form of the Q argument, it's what an interlocutor is leaning on when they say "scholars say the earliest Jesus didn't claim to be God."
The case against Q-stratification overreach
Even within Q-affirming scholarship, the Crossan-Mack-Robinson reconstruction is widely rejected:
- Stratification is double-hypothetical. Q itself is hypothetical; Q1/Q2/Q3 are stratified layers within that hypothesis. You can't ground a confident reconstruction of "the historical Jesus" on layers of speculation.
- Wisdom and apocalyptic are inseparable in Q. The Beatitudes presuppose the apocalyptic reversal they describe ("blessed are you who weep now, for you shall laugh"). Removing the apocalyptic from Q1 mutilates even the wisdom material.
- Dale Allison (a Q-affirming scholar) has demonstrated in Jesus of Nazareth: Millenarian Prophet (1998) that the apocalyptic Jesus is firmly grounded in the earliest recoverable tradition, including Q's apocalyptic material, which can't be peeled off without circular reasoning.
- N. T. Wright (Jesus and the Victory of God, 1996) argues the Cynic-sage hypothesis is implausible on Jewish-historical grounds: a non-apocalyptic, non-Messianic Jesus does not fit 2nd-Temple Jewish context.
- The pre-Pauline credal tradition predates any Q stratum. The 1 Cor 15:3-7 creed, datable to within ~5 years of the resurrection (see Pre-Pauline Creeds), already contains atoning death, bodily resurrection, and Kyrios Christology. No Q-stratification can produce a "pre-Christian-Christ" Jesus that pre-dates this attested credal material.
The Q-stratification project is one of the clearest cases in NT scholarship of methodology outrunning evidence. Even sympathetic Q-scholars (Tuckett, Allison, Kloppenborg himself) distance themselves from the Crossan-Mack reconstruction.
How to talk about Q in apologetics
When an interlocutor invokes Q, typically as "the earliest Jesus tradition shows a non-divine, non-resurrected wisdom teacher", work through these steps in order:
Step 1, Distinguish three claims
The interlocutor is conflating three increasingly speculative claims:
- Q exists as a literary source (debated; ~60-70% of scholars agree).
- Q has stratified layers (Kloppenborg, debated).
- Q1 represents the historical Jesus and Christianity is a later overlay (Crossan / Mack, minority even within Q-affirming scholarship).
Make them name which claim they're making. The first is respectable critical scholarship. The third is methodologically reckless.
Step 2, Note that Q is unattested
Q is hypothetical. There is no manuscript, no patristic citation, no quotation. The interlocutor invoking "what Q says" is invoking a reconstructed text whose very existence is contested. Mention Mark Goodacre's The Case Against Q (2002): a respected, mainstream NT scholar at Duke who argues Q probably doesn't exist. The conversation should not proceed as though Q is settled.
Step 3, Ask what we do have
If we set Q aside, what attested sources do we have for the earliest Christian theology?
- The pre-Pauline creed in 1 Cor 15:3-7, datable to ~AD 36-38, within 5 years of the resurrection. Affirms atoning death, burial, bodily resurrection, named eyewitnesses.
- The Christ-hymn in Phil 2:6-11, pre-Pauline, datable to ~AD 30s-40s. Affirms pre-existence, incarnation, Kyrios exaltation.
- Romans 10:9, pre-Pauline baptismal confession ("Jesus is Kyrios").
- The Aramaic Maranatha (1 Cor 16:22), pre-Pauline Aramaic prayer addressed to the risen Christ.
These are attested in the actual NT manuscripts, datable on their own internal evidence, and cumulatively contradict the Q-stratified-Jesus reconstruction. See Pre-Pauline Creeds for the full catalog.
Step 4, Show that even granting Q, the conclusion doesn't follow
Even if Q exists, even if Kloppenborg's stratification is correct, the Crossan-Mack inference still fails:
- Argument from silence, Q's silence on the Passion (if it was silent) doesn't mean the Passion wasn't central; Q was a different genre.
- Q is supplementary, it's a sayings collection, not a complete gospel. Its silence on X tells us nothing about whether X mattered to the community.
- The sapiential / apocalyptic split doesn't track historical chronology, Allison and others have shown that Jesus's wisdom and apocalyptic teaching are intertwined throughout the earliest tradition.
Step 5, Pivot to the strongest ground
End on the pre-Pauline creeds, not on defending Q's nonexistence. The Christian apologetic does not depend on Q being false. It depends on the attested credal tradition being what the earliest Christians believed, which it was, regardless of what one thinks about Q.
Steel-man rules
Don't deny Q exists categorically, that overreaches against majority scholarship and weakens credibility. Better posture:
"The Q hypothesis is a respectable critical-scholarly position that I take seriously. I lean toward the Farrer alternative, following Goodacre, but the question is genuinely open. What's not open is the dating of the pre-Pauline credal tradition in 1 Corinthians 15, that's within five years of the resurrection, and it already contains everything you say is a later development."
Conversely, don't embrace Q reflexively. Conservative evangelical scholars are mixed:
| Scholar | Position |
|---|---|
| Craig Blomberg | Two-Source / Q (cautious) |
| D. A. Carson | Two-Source / Q |
| Darrell Bock | Two-Source / Q (with reservations) |
| N. T. Wright | Two-Source / Q (with reservations) |
| Eta Linnemann | Anti-Q (rejects synoptic-source criticism altogether) |
| Robert Thomas / F. David Farnell | Anti-Q (independence hypothesis) |
| Eckhard Schnabel | Sympathetic to Farrer |
The Christian apologist has room to take any of these positions; what's not allowed is ignoring the question.

- NT Authorship and Eyewitness Apologetics, the broader apologetic frame
- Historicity of Jesus, the question Q is sometimes invoked to undermine
- Pre-Pauline Creeds, the attested earliest-doctrine material that defeats Q-stratified-Jesus reconstructions
- Didache, earliest extra-canonical witness; corroborates the Trinitarian baptismal formula and eucharist
