The Stoic philosophers had developed the concept of the logos into one of the most sophisticated ideas in ancient philosophy. For them, the logos was the universal reason pervading and ordering all things β the principle that made the cosmos a cosmos (an ordered whole) rather than chaos. When Marcus Aurelius wrote his Meditations, he was addressing himself to a universe structured by logos. Heraclitus, centuries earlier, had proposed that all things flow and change but the logos underlying them is eternal and constant. This was not an obscure academic concept. It was common intellectual currency across the Greco-Roman world.
The Jewish philosopher Philo of Alexandria, a contemporary of Jesus, had already been working to synthesize the Greek logos concept with the Hebrew concept of the Word of God (dabar, memra). For Philo, the logos was the intermediary between the transcendent God and the created world β the first-born son of God, the instrument of creation. Philo never identified the logos with a historical person. He kept it as a philosophical concept. John's move was to name one.
When John wrote "In the beginning was the Word," the opening words en arche echoed Genesis 1:1 in Greek β "in the beginning God created." Every Jewish reader caught it. When he continued "and the Word was with God, and the Word was God," every Greek reader recognized the logos. John was speaking to both audiences at once, and both would have understood that something unprecedented was being claimed. The logos β the organizing principle of all reality β was personal, was with God, and was God. And then, in verse 14, the statement that no Greek philosopher had ever risked: "the Word became flesh."
