Although the verses read as today’s Gospel reading come from an earlier part of the Gospel according to St. John, the theme of that passage fits well into the Easter Season. If we think prayerfully about it I think you can see that it is possible to understand it on several levels. In the original context of these verses I think that Jesus was speaking of bread as representing the spirit of his teaching about God and about love.
When those words were spoken at the synagogue in Capernaum nobody would have understood them as we can today. At most it might only have been seen in terms of the love that God has for us, and the love that we have for one another.
Only when we think about it prayerfully can the Gospel Reading for today’s Eucharist be understood as referring to the Bread and Wine of the Holy Eucharist as Jesus presence with us and for us in the Holy Eucharist, as well as being his presence with us in his teaching. But that would be reading a later meaning into it than either Jesus or St. John may have intended originally when those words were first spoken..
