The Word became flesh. He did not simply appear to be flesh. He was not “faking it,” to use modern terminology. Jesus was not simply some phantom or spirit masquerading as a real human being. He became flesh. John uses a term that was easily understandable in his day. It’s not an unusual word. At times it refers solely to flesh, as in the material stuff of our bodies. At other times it refers to the whole human nature. In any case, its meaning could not be missed. The Logos entered into the physical realm. He became a human being, a real, living, breathing human being.
