… those earliest Eucharistic meals were not our present morsel-and-sip ritual but a true meal, called the Lord’s Supper because it was the style of share-meal created by Jesus as a meal-symbol of equality within a community that believed in God’s ownership of food as the material basis of life itself. The radicality of God’s egalitarian Christian meal opposed the normalcy of Rome’s hierarchically patronal meal.
Thus John Dominic Crossan in his fascinating book God and Empire: Jesus against Rome, Then and Now.
