While celebrating Passover as a Jew with his friends, Jesus reinvents the ritual and verbally replaces the paschal lamb. This gesture, narrated by Paul and the Synoptic Gospels, becomes foundational to the Christian religious tradition. Jesus sacrifices himself for all in a vicarious capacity, sealing the practice. From then on, the bond of communion is guaranteed and literally nourished by participation in the Eucharistic supper.
Despite its singular literary form, however, it reveals itself in a plurality of variants. Christians, in fact, are divided at that single table. The different Christian denominations do not share the same understanding of Christ's presence in the bread and wine, foods necessary for the celebration. Furthermore, Christians are not always the same with respect to the meal. In some confessions, those marked by hierarchical structures, different roles entail different prerogatives at the meal. And, in these cases, the hierarchy exercises actual control over the meal, even excluding participants, based not only on codified norms but also on the charisma actually recognized by the communities. What, then, nourishes this food, and with whom does it strengthen bonds of communion?
