It is often said that the discourse on the bread of life in John 6 is about the Eucharist. Occurring after our Lord's feeding of the many with loaves and fish, this speech is about faith, eating flesh, drinking blood, partaking, abiding, and eternal life - all pregnant with mystery. Roman Catholics are fond of relating this to transubstantiation, and Christians in general think it is about the Eucharist, but is it? The institution of the Lord's Supper does not properly occur in John's Gospel. The only reference is indirect: he reports "the supper being ended..." (13:2), and "He riseth from supper..." (13:4) to wash the disciples' feet; thus begins the Farewell Discourse. There is nothing about the Eucharist. John is alone in mentioning the water changed into wine at Cana, and the words "it is finished", when Christ Jesus finished the passover by partaking of the bitter substance upon the Cross. Were all these events about eating, drinking, spirit and flesh, to be seen in the light of the Eucharist, or are we imprinting the Eucharist on passages that are about faith in Jesus Christ, and the metaphors He used to describe it? I wonder whether John 6, specifically, has anything to do with the Eucharist: the celebration and sacrament. The Lord said that partaking of his body and blood is eternal life, but he also said "the words that I speak to you are spirit and life" and did not later tie these words in with the Eucharist, in John's report. Any thoughts, words of the Church Fathers, scriptural comparisons, essays, or articles on this? This is just a question... I have no answers or biases toward certain answers... I just want to know what it's all about.
