The literary puzzle of the three Gospels that scholars cannot solve
Matthew, Mark, and Luke share strikingly similar stories, often using nearly identical wording. This intense parallelism suggests they weren't just independent witnesses, but were likely reading and rewriting one another. Yet, after centuries of intense study, the true nature of their relationship remains one of history's great unsolved mysteries.
The term 'synoptic' comes from the Greek *synopsis*, meaning 'seeing all together.' This describes the unique relationship between the Gospels of Matthew, Mark, and Luke. Unlike the Gospel of John, which offers a distinct perspective, the Synoptics share a massive amount of overlapping material known as the 'triple tradition.' In some cases, the overlap is profound: Robert H. Stein notes that 97.2 percent of the words in Mark find a parallel in Matthew, and 88.4 percent appear in Luke.
This similarity has birthed the 'Synoptic Problem,' a debate over how these texts were composed. For much of the 20th century, the 'two-source theory' dominated. This hypothesis suggests 'Marcan priority'—that Mark was written first and used by both Matthew and Luke—alongside a lost, hypothetical document called 'Q' (from the German *Quelle*, meaning source) which provided shared sayings. This 'Q' source is thought to account for the 'double tradition,' the roughly 200 verses shared by Matthew and Luke but absent from Mark.
However, the consensus is fracturing. Modern scholars are exploring the 'Farrer hypothesis,' which suggests Luke simply used Matthew directly, removing the need for 'Q' entirely. Others are revisiting the 'Augustinian hypothesis,' which posits a sequential dependence (Matthew, then Mark, then Luke). While some recent statistical models suggest Luke was likely the last to be composed and Mark the least likely, no definitive solution exists. The debate continues to oscillate between theories of complex literary dependence and the power of ancient oral traditions and shared memory.
