Here it is important to consider what the Synod Fathers described as eucharistic consistency, a quality which our lives are objectively called to embody. Worship pleasing to God can never be a purely private matter, without consequences for our relationships with others: it demands a public witness to our faith. Evidently, this is true for all the baptized, yet it is especially incumbent upon those who, by virtue of their social or political position, must make decisions regarding fundamental values, such as respect for human life, its defence from conception to natural death, the family built upon marriage between a man and a woman, the freedom to educate one's children and the promotion of the common good in all its forms. Those values are not negotiable. Consequently, Catholic politicians and legislators, conscious of their grave responsibility before society, must feel particularly bound, on the basis of a properly formed conscience, to introduce and support laws inspired by values grounded in human nature. There is an objective connection here with the Eucharist. Bishops are bound to reaffirm constantly these values as part of their responsibility to the flock entrusted to them.
The first and fundamental mission that we receive from the sacred mysteries we celebrate is that of bearing witness by our lives. The wonder we experience at the gift God has made to us in Christ gives new impulse to our lives and commits us to becoming witnesses of his love. We become witnesses when, through our actions, words and way of being, Another makes himself present.
In the memorial of his sacrifice, the Lord strengthens our fraternal communion and, in a particular way, urges those in conflict to hasten their reconciliation by opening themselves to dialogue and a commitment to justice. Certainly, the restoration of justice, reconciliation and forgiveness are the conditions for true peace. The recognition of this fact leads to the determination to transform unjust structures and to restore respect for the dignity of all men and women, created in God's image and likeness. Through the concrete fulfilment of this responsibility, the Eucharist becomes in life what is signifies in its celebration. As I have had occasion to say, it is not the proper task of the Church to engage in the political work of bringing about the most just society possible; nonetheless she cannot and must not remain on the sidelines in the struggle for justice. The Church "has to play her part through rational argument and she has to reawaken the spiritual energy without which justice, which always demands sacrifice, cannot prevail and prosper."
We must denounce those who squander the earth's riches, provoking inequalities that cry out to heaven. For example, it is impossible to remain silent before the "distressing images of huge camps throughout the world of displaced persons and refugees, who are living in makeshift conditions in order to escape a worse fate, yet are still in dire need. Are these human beings not our brothers and sisters? Do their children not come into the world with the same legitimate expectations of happiness as other children?" The Lord Jesus, the bread of eternal life, spurs us to be mindful of the situations of extreme poverty in which a great part of humanity still lives: these are situations for which human beings bear a clear and disquieting responsibility. Indeed, "on the basis of available statistical data, it can be said that less than half of the huge sums spent worldwide on armaments would be more than sufficient to liberate the immense masses of the poor from destitution. This challenges humanity's conscience.
Finally, to develop a profound eucharistic spirituality that is also capable of significantly affecting the fabric of society, the Christian people, in giving thanks to God through the Eucharist, should be conscious that they do so in the name of all creation, aspiring to the sanctification of the world and working intensely to that end. The Eucharist itself powerfully illuminates human history and the whole cosmos. In this sacramental perspective we learn, day by day, that ever ecclesial event is a kind of sign by which God makes himself known and challenges us. The eucharistic form of life can thus help foster a real change in the way we approach history and the world.
