This cut and paste stuff does not help. Go consult the traditions of the early Church fathers and the great theologians from Augustine to Aquinas to Benedict and also the great Lutheran theologians from Richard Nehaus to Anglicans like Henry Newman (after whom university theological clubs have been set) who converted to Catholicism and found the errors in this interpretation. This is the stuff that has repeatedly been discussed and effectively rebuffed for over 2000 years. The context is clear to the point that those who remained with Him like Peter, James, and John all understood what He meant. The books in the Bible did not fall from the skies. They were authoritatively selected by the early Church Fathers who found that these books ratified the received oral traditions on the nature of the Eucharist that was handed down for the sixty years before the books were ever written.
AMEN.
