Bread Of Life
John does not narrate the Last Supper words.
Instead, John gives a long bread discourse after the feeding of the five thousand. The crowd remembers manna: “He gave them bread from heaven to eat.” Jesus answers, “I am the bread of life.”1
The move is enormous. Manna becomes a sign that points beyond itself. Bread language is gathered into Christ’s identity.
Then the discourse becomes more difficult. Jesus speaks of giving his flesh for the life of the world. He says that those who eat his flesh and drink his blood have eternal life.2
Many readers hear this through later Eucharistic theology. Some scholars caution that John’s sacramental language works differently from the Synoptic institution narratives. That caution is fair.3
For this book, the basic point is enough. John makes bread the grammar of divine life.
Grammar means the structure through which meaning is expressed. In John 6, bread no longer only supports the body, as in The Staff of Bread. Bread becomes the language through which Christ names himself.
That intensifies the cultural inheritance. A food can be debated. A sign of divine life cannot be handled so casually.
