A metaphorical reading of eating Jesus’ flesh in John 6 is insufficient. It keeps the reader from seeing the connection between Jesus’ self-giving and his divinity; it does not reckon with the communication of divinity to communicants; it does not allow for our participation in the life of God through the ascent of the incarnate Word.
