In Christology, the conception that the Christ is the Logos (i.e. The Word) has been important in establishing the doctrine of the divinity of Christ and his position as God the Son in the Trinity as set forth in the Chalcedonian Creed. The conception derives from the opening of the Gospel of John, commonly translated into English as: "In the beginning was the Word, and the Word was with God, and the Word was God." In the original Greek, Logos (λόγος) is used for "Word," and in theological discourse, this is often left untranslated.
