The Paschal Mystery is the New Covenant – not that the Old has gone [there is only one covenant]. New means greater depth of intimacy with universal outreach. Jesus takes the Law and the Prophets – Israel’s heritage – and through this loves his people into existence. By the end of his short life they were still in receiving mode, not yet deepening into giving what was received and so, as Scripture says, he loved them to the end; handing over his Spirit which has lived and a human existence to the Father to give to all willing to receive – Pentecost.
To sustain and feed them along this new way he gives himself as the bread of life; not like the feeding of the 5,000. Being with him at the Last Supper, eating the bread he broke, accepting his death is to continue his way; to come together to break bread and become sustaining food for others. The Covenant Community was set up at that supper table. This is why there is much more involved in celebrating the Eucharist than a memorial experience; it is to accept his presence through his death, to become body given and blood poured out for others – service.
The Eucharist is the mystery of God’s graciousness and our salvation. Transubstantiation is a word for something we cannot understand, something beyond the competence of human language; to claim to capture it is to nullify the challenge to attune the way we live so as to address the cry of the poor. Augustine [who used the word Transubstantiation] says we are present not to satisfy personal needs [or commandments] but to be attentive and proactive to the cry of the poor. We cannot appreciate Transubstantiation if we by-pass the challenge for personal change.
The Eucharist is the real presence, not just a memorial ritual. It is Presence there for our presence, so that what is in him can be in us. Jesus does not stand-in for us, but invites us to get involved. We cannot receive the Eucharist in passive ways – the fruit of the Eucharist is one community allowing God’s love to be felt in our world.
