Q Source Theories: Reconstructing the Lost Gospel

In the landscape of biblical scholarship, few hypotheses have proven as enduringly significant as the existence of the Q source—a lost document believed to have been used independently by the authors of the gospels of Matthew and Luke. Though no physical manuscript of Q has ever been discovered, its shadow looms large across our understanding of early Christianity and the formation of the New Testament. This book undertakes a comprehensive exploration of Q source theories, examining the evidence for this hypothetical document, methods for its reconstruction, and its implications for understanding the origins and development of Christianity. The quest to understand the relationships among the first three canonical gospels—Matthew, Mark, and Luke, collectively known as the Synoptic Gospels—has occupied scholars for centuries. The remarkable similarities in content, structure, and even exact wording among these texts demand explanation, as do their equally significant differences. In the late eighteenth and early nineteenth centuries, scholars began developing more systematic approaches to what became known as the "Synoptic Problem," the literary puzzle of how these three texts relate to one another. Out of this inquiry emerged the Two-Source Hypothesis, which proposes that both Matthew and Luke independently used two main sources: the Gospel of Mark and a now-lost collection of Jesus's sayings that scholars have designated "Q" (from the German Quelle, meaning "source").
