"Quelle" is a German word that translates to "source" in English. It holds significant meaning in both everyday usage and academic contexts. In general terms, "Quelle" refers to the origin or starting point of something, such as a water source or the source of information. In scholarly work, particularly in history, theology, and biblical studies, "Quelle" often refers to a hypothetical written source. One of the most notable examples is the "Q source" (from "Quelle"), a supposed document that scholars believe was used in the composition of the Gospels of Matthew and Luke in the New Testament. Although no physical copy of the Q source has been found, its existence is inferred from textual similarities. In journalism and research, citing the "Quelle" is crucial for credibility and transparency. Overall, "Quelle" emphasizes the importance of identifying where information or material originates, reflecting the value of authenticity and accuracy.
