You are, as I said in the letter I sent you last year, a veritable invisible army; you are a fundamental part of that humanity that fights for life against a system of death. In this engagement I see the Lord who makes Himself present in our midst, to give to us His Kingdom as a gift. When He offered us the standard by which we will be judged (cf. Mt 25: 31-46), Jesus told us that salvation consists in taking care of the hungry, the sick, prisoners, foreigners; in short, in recognizing Him and serving Him in all suffering humanity. That is why I wish to say to you: “Blessed are those who hunger and thirst for justice, for they shall be satisfied” (Mt 5: 6), “Blessed are the peacemakers, for they shall be called children of God” (Mt 5: 9). We want this beatitude to expand, to permeate and anoint every corner and every space where life is threatened. But it happens to us as people, as communities, as families and even individually, that we have to face situations that paralyze us, where the horizon disappears and bewilderment, fear, powerlessness and injustice seem to take over the present. We also experience resistance to the changes we need and long for, many forms of resistance that run deep, that are rooted beyond our strength and decisions. They are what the Social Teaching of the Church calls structures of sin; these too we are called to change, and we cannot overlook them in the moment of thinking of how to act. Personal change is necessary, but it is also indispensable to adjust our socio-economic models so that they have a human face, because many models have lost it. And thinking about these situations, I make a pest of myself with my questions. And I go on asking. And I ask everyone in the name of God.
