The feeding didn't save, or alter a single one of them according to the words of the Lord. He stated that they continued to follow him to keep their belly filled. The eucharist is a total fiction, intended to spiritually enslave weak believers. It is not in any way supported by the gospels. Taken in context, verse 53 has to agree with the preceeding verses, thus the eating and drinking is completely spiritual, as stated by the Lord in verse 63.
That statement is equivalent to calling Jesus Christ a total fiction.
No Christ, no Eucharist. No Eucharist, no Christ.
"I am the living bread."
