The “Bread of Life Discourse” in John 6 is often read sacramentally and used as justification for eucharistic beliefs regarding true-presence. Though the evangelist of the Gospel deals with chronology differently than modern authors and readers, the sacramental-sounding language in the “Bread of Life Discourse” does not necessarily mean that the passage is referring to the establishment of the Eucharist at the Last Supper. The main point of the “Bread of Life Discourse” is to emphasize faith in Jesus through the metaphor of bread, continuing the dominant theme in the entire chapter of John 6.
