The parable of the Good Samaritan . . . belongs to the Gospel of suffering, goes hand in hand with this Gospel through the history of the Church and Christianity, through the history of man and humanity. This parable witnesses to the fact that Christ’s revelation of the salvific meaning of suffering is in no way identified with an attitude of passivity. Completely the reverse is true. The Gospel is the negation of passivity in the face of suffering. Christ himself is especially active in this field. In this way he accomplishes the messianic program of his mission, according to the words of the prophet: “The Spirit of the Lord is upon me, because he has anointed me to preach good news to the poor. He has sent me to proclaim release to the captives and recovering of sight to the blind, to set at liberty those who are oppressed, to proclaim the acceptable year of the Lord”. In a superabundant way Christ carries out this messianic program of his mission: he goes about “doing good”. and the good of his works became especially evident in the face of human suffering. The parable of the Good Samaritan is in profound harmony with the conduct of Christ himself.
Finally, this parable, through its essential content, will enter into those disturbing words of the Final Judgment, noted by Matthew in his Gospel: “Come, O blessed of my Father, inherit the kingdom prepared for you from the foundation of the world; for I was hungry and you gave me food, I was thirsty and you gave me drink, I was a stranger and you welcomed me, I was in prison and you came to me”. To the just, who ask when they did all this to him, the Son of Man will respond: “Truly, I say to you, as you did it to one of the least of these my brethren, you did it to me”. The opposite sentence will be imposed on those who have behaved differently: “As you did it not to one of the least of these, you did it not to me”.
One could certainly extend the list of the forms of suffering that have encountered human sensitivity, compassion and help, or that have failed to do so. The first and second parts of Christ’s words about the Final Judgment unambiguously show how essential it is, for the eternal life of every individual, to “stop”, as the Good Samaritan did, at the suffering of one’s neighbor, to have “compassion” for that suffering, and to give some help. In the messianic program of Christ, which is at the same time the program of the Kingdom of God, suffering is present in the world in order to release love, in order to give birth to works of love towards neighbor, in order to transform the whole of human civilization into a “civilization of love”. In this love the salvific meaning of suffering is completely accomplished and reaches its definitive dimension. Christ’s words about the Final Judgment enable us to understand this in all the simplicity and clarity of the Gospel.
These words about love, about actions of love, acts linked with human suffering, enable us once more to discover, at the basis of all human sufferings, the same redemptive suffering of Christ. Christ said: “You did it to me”. He himself is the one who in each individual experiences love; he himself is the one who receives help, when this is given to every suffering person without exception. He himself is present in this suffering person, since his salvific suffering has been opened once and for all to every human suffering. And all those who suffer have been called once and for all to become sharers “in Christ’s sufferings”, just as all have been called to “complete” with their own suffering “what is lacking in Christ’s afflictions”. At one and the same time Christ has taught man to do good by his suffering and to do good to those who suffer. In this double aspect he has completely revealed the meaning of suffering. – from Salvifici Doloris, the pope’s Apostolic Letter of February 11. 1984
