39 To suffer with the other and for others; to suffer for the sake of truth and justice; to suffer out of love and in order to become a person who truly loves—these are fundamental elements of humanity, and to abandon them would destroy man himself. Yet once again the question arises: are we capable of this? Is the other important enough to warrant my becoming, on his account, a person who suffers? Does truth matter to me enough to make suffering worthwhile? Is the promise of love so great that it justifies the gift of myself? In the history of humanity, it was the Christian faith that had the particular merit of bringing forth within man a new and deeper capacity for these kinds of suffering that are decisive for his humanity. The Christian faith has shown us that truth, justice and love are not simply ideals, but enormously weighty realities. It has shown us that God —Truth and Love in person—desired to suffer for us and with us. Bernard of Clairvaux coined the marvellous expression: Impassibilis est Deus, sed non incompassibilis —God cannot suffer, but he can suffer with . Man is worth so much to God that he himself became man in order to suffer with man in an utterly real way—in flesh and blood—as is revealed to us in the account of Jesus's Passion. Hence in all human suffering we are joined by one who experiences and carries that suffering with us; hence con-solatio is present in all suffering, the consolation of God's compassionate love—and so the star of hope rises. Certainly, in our many different sufferings and trials we always need the lesser and greater hopes too—a kind visit, the healing of internal and external wounds, a favourable resolution of a crisis, and so on. In our lesser trials these kinds of hope may even be sufficient. But in truly great trials, where I must make a definitive decision to place the truth before my own welfare, career and possessions, I need the certitude of that true, great hope of which we have spoken here. For this too we need witnesses—martyrs—who have given themselves totally, so as to show us the way—day after day. We need them if we are to prefer goodness to comfort, even in the little choices we face each day—knowing that this is how we live life to the full. Let us say it once again: the capacity to suffer for the sake of the truth is the measure of humanity. Yet this capacity to suffer depends on the type and extent of the hope that we bear within us and build upon. The saints were able to make the great journey of human existence in the way that Christ had done before them, because they were brimming with great hope.
