[T]he sacraments constitute the events of a time which is the tension between the Resurrection and the Parousia …. Thus during the delay of the Parousia, the Eucharist prevents humanity, in this foretaste of celestial food …. And the Eucharist is the sacrament of unity which gathers about Christ of glory, present in the community, all nations in order to offer them through His hands to the Father.
