God’s heart has a special place for the poor, so much so that he himself “became poor” (2 Cor 8:9). The entire history of our redemption is marked by the presence of the poor. Salvation came to us from the “yes” uttered by a lowly maiden from a small town on the fringes of a great empire. The Saviour was born in a manger, in the midst of animals, like children of poor families; he was presented at the Temple along with two turtledoves, the offering made by those who could not afford a lamb (cf. Lk 2:24; Lev 5:7); he was raised in a home of ordinary workers and worked with his own hands to earn his bread. When he began to preach the Kingdom, crowds of the dispossessed followed him, illustrating his words: “The Spirit of the Lord is upon me, because he has anointed me to preach good news to the poor” (Lk 4:18). He assured those burdened by sorrow and crushed by poverty that God has a special place for them in his heart: “Blessed are you poor, yours is the kingdom of God” (Lk 6:20); he made himself one of them: “I was hungry and you gave me food to eat”, and he taught them that mercy towards all of these is the key to heaven (cf. Mt 25:5ff.).
For the Church, the option for the poor is primarily a theological category rather than a cultural, sociological, political or philosophical one. God shows the poor “his first mercy.” This divine preference has consequences for the faith life of all Christians, since we are called to have “this mind… which was in Jesus Christ” (Phil 2:5). Inspired by this, the Church has made an option for the poor which is understood as a “special form of primacy in the exercise of Christian charity, to which the whole tradition of the Church bears witness.” This option – as Benedict XVI has taught – “is implicit in our Christian faith in a God who became poor for us, so as to enrich us with his poverty.” This is why I want a Church which is poor and for the poor. They have much to teach us. Not only do they share in the sensus fidei, but in their difficulties they know the suffering Christ. We need to let ourselves be evangelised by them. The new evangelisation is an invitation to acknowledge the saving power at work in their lives and to put them at the centre of the Church’s pilgrim way. We are called to find Christ in them, to lend our voice to their causes, but also to be their friends, to listen to them, to speak for them and to embrace the mysterious wisdom which God wishes to share with us through them.
