“The Eucharist is the food reserved for those who in Baptism were delivered from slavery and have become sons; it is the food that sustained them in the long journey of the Exodus through the desert of human existence.  Like the manna for the people of Israel, for every Christian generation the Eucharist is the indispensable nourishment that sustains them as they cross the desert of this world, parched by the ideological and economic systems that do not promote life bur rather humiliate it.  It is a world where the logic of power and possession prevails rather than that of service and love; a world where the culture of violence and death is frequently triumphant.  Yet Jesus comes to meet us and imbues us with certainty: he himself is the ‘Bread of Life’.  He repeated this to us in the words of the Gospel Acclamation: ‘I am the living bread from Heaven; if anyone eats of this bread, he will live for ever.”  Pope Benedict XVI.
