Why Only Matthew Records the Sermon on the Mount
This paper investigates why the Sermon on the Mount appears in complete form only in the Gospel of Matthew, using this puzzle as a lens through which to examine competing scholarly theories about the origins of the four canonical gospels. The paper surveys the orthodox divine-inspiration explanation, the Markan priority hypothesis, the Q source theory, the possible influence of the Gospel of Thomas, and the more speculative proposal that Roman playwright Seneca shaped the gospel narratives. By tracing each theory to its implications for the sermon's unique placement, the paper demonstrates how a single textual anomaly opens onto broad debates in New Testament scholarship.
- Introduction: A Puzzling Omission: Four gospels, one complete Sermon on the Mount
- The Orthodox Explanation and Divine Will: Divine inspiration explains gospel differences and similarities
- Markan Priority and the Synoptic Problem: Mark written first; Matthew and Luke depend on it
- The Q Source Hypothesis: Lost sayings document explains shared Matthew-Luke content
- The Gospel of Thomas and Gnostic Influences: Thomas gospel may have inspired synoptic sermon passages
- The Seneca Theory and Wisdom Teachings: Roman playwright Seneca possibly shaped gospel narratives
- Conclusion: No single theory fully resolves the sermon's omission

What makes this paper effective
- The paper anchors a broad scholarly debate to a single, concrete textual question — why the Sermon on the Mount appears fully only in Matthew — giving the survey of theories a clear unifying purpose.
- It presents multiple competing hypotheses fairly and in a logical sequence, moving from the most orthodox to the most speculative, which gives the argument a natural sense of escalating complexity.
- The use of direct textual comparison (the three parallel beatitude quotations from Matthew, Luke, and Thomas) provides concrete evidence that grounds the more abstract theoretical discussion.
Key academic technique demonstrated
The paper demonstrates comparative textual analysis alongside a survey of scholarly hypotheses. By placing three near-identical verses from different sources side by side, the writer shows rather than tells why source-dependency theories are credible — a technique central to biblical and literary scholarship.
Structure breakdown
The paper opens with an introduction identifying the puzzle, then moves through five explanatory theories in roughly ascending order of heterodoxy: divine will, Markan priority, the Q document, the Gospel of Thomas, and the Seneca hypothesis. Each section connects its theory back to the central question about the sermon's singular appearance. A brief conclusion acknowledges the irresolvability of the question while affirming its significance.
Introduction: A Puzzling Omission
There are four gospels in the Bible, each purporting to tell the true story of Jesus' time on earth. In these four books, the famous Sermon on the Mount is recorded in full only once — in Matthew — though a much abridged version appears in Luke, reportedly delivered after Christ had descended from that same mountain. Understandably, no single short book could possibly encompass all the events of any man's life, let alone the life of a wise prophet and Messiah. It seems odd that this sermon is not recorded elsewhere — not because each of the gospels should be expected to cover the same episodes, as if there were no others, but rather because generally speaking they do stick to the same canon of stories.
Matthew, Mark, and Luke are referred to as the synoptic gospels because they are interwoven with one another and tend to portray the same events. John is the odd gospel out, appearing interested in different parables and stories. The inclusion of four gospels, all of which tell slightly different and at times inconsistent stories, has led to a great deal of speculation among scholars as to which are most accurate and where between their lines the "real" story lies. In order to thoroughly examine why there is only one complete telling of the Sermon on the Mount across four gospels, it is necessary to understand the many competing theories about why there are four gospels and what the connections between them may be.
The Orthodox Explanation and Divine Will
The most obvious and orthodox answer to this question can be summed up in one word: God. To be more precise — what God wants, God gets, and one does not question God. This theory suggests that each author was divinely instructed as to precisely what words should be used. Similarities between gospels are therefore evidence that God was dictating the literal words of Jesus, while differences may be attributed to metaphor, mystery, or the possibility of dual truths. For example, some claim that the different lineages recorded in Matthew and Luke come from tracing Jesus' lineage alternately through his adoptive father and through his mother. Old orthodoxy would link the number of gospels to the divine will of God: "Why were there only four? St. Irenaeus explained: 'There are four principal winds, four pillars that hold up the sky, and four corners of the universe; therefore, it is only right that there be four gospels.'"
According to this explanation, one may be sure that the Sermon on the Mount appears in the Bible only once because God, in his inscrutable knowledge, willed this to be the case.
