So, when it comes to the Sacrament of the Altar, which as I see it is the sublimest myth known to humanity, we have powerful archetypal symbols that not only commemorate in symbol the metaphysical and spiritual ideas to which I have made reference, they enable all who participate in the ceremony with sincerity, right intention, and purpose to actually take part, both interiorly and exteriorly, in that sacred mystery drama ('self-same sacrifice,' in the words of one Christian liturgy) that is going on all the time wherever there is life. Not only that, but we have a powerful ritual that (to borrow from one Christian liturgy) serves to 'perpetuate within the limitations of time and space ... the enduring sacrifice by which the world is nourished and sustained.'
Here’s something else. The Eucharist is a powerful transformative ritual. You see, we are the bread and the wine. The bread (cf flesh) may be said to represent our terrestrial, mortal life, whilst the wine (cf blood) signifies our spiritual life. Conjointly, both represent or signify our lower and higher natures respectively. So, we should place upon the paten all our joys and sorrows along with all our hopes, fears, negativity, and disappointments---everything, in fact. We can also place upon the paten all those we love and for whom we care. And that drop of water added to the wine and cast into the chalice---that, too, represents us, indeed every moment of our lives as well as the lives and sufferings of others whom we love and for whom we care. Yes, we offer ourselves so that we can be consecrated, that is, transformed into new and better people. Of course, it is not magic. We need to die to our old, tired, false selves in order to be resurrected into our True Self, the latter being the very best person we can be. That requires, among other things, self-surrender … on a daily basis. Fulton J Sheen, in his inimitably beautiful manner of writing, has written:
In all respects, the Divine is the creative, dynamic, and transformative principle of life and love---in particular, suffering love---that forever gives of itself to itself so as to enable life to continue and grow. It is the power that brings peace, works for unity and wholeness, forgives, cleanses, heals, revitalizes, refreshes, renews, and recreates. It is the principle of oneness, wholeness, and holiness. It is 'the peace that passeth understanding' (cf Phil 4:7). There is nothing in the world quite like it, and the great mystery drama of the Eucharist is a living symbol and regular re-presentation of this Divine Power and Presence. Indeed, it's all of life.
Yes, the microcosm is the macrocosm. The One, which forever becomes the many, and the many are one. And so it is.
