ISB ~ John 6 v35 - 59
The Bread of Life discourse. Interpretations of this sermon often take one of two positions. Some think of the discourse as an extensive invitation to faith, so that eating the bread of life is seen as a metaphor for believing in Jesus. Others interpret the discourse along sacramental lines, so that eating the bread of life means partaking of the Eucharist. Both of these views are true and can be correlated with a natural and symmetrical division of the sermon into two parts. (1) Invitation to Faith (6:35-47). The first half of the discourse opens with the statement āI am the bread of lifeā (6:35). This is followed by a string of invitations to come to Jesus and believe in him for salvation. The metaphorical import of Jesusā teaching is so obvious that it stands out in the response of the Jews, who ask him, not why he calls himself bread, but how he can claim to have descended from heaven (6:42). (2) Invitation to the Eucharist (6:48-58). The second half of the discourse likewise opens with the statement āI am the bread of lifeā (6:48). This is followed by a string of invitations to eat the flesh of Jesus and drink his blood. Here the literal import of Jesusā teaching is so obvious that it, too, stands out in the response of the Jews, who ask how it is possible to consume his flesh (6:52). In the end, these two halves of the sermon work in tandem, since without faith we can neither be united with Christ nor recognize his presence in the Eucharist. If eating is believing in 6:3547, then believing leads to eating in 6:48-58
