"Love one another as I love you"
The true measure of humanity is essentially determined in relationship to suffering and to the sufferer. This holds true both for the individual and for society. A society unable to accept its suffering members and incapable of helping to share their suffering and to bear it inwardly through “com-passion” is a cruel and inhuman society... The Latin word con-solatio, “consolation”, expresses this beautifully. It suggests being with the other in his solitude, so that it ceases to be solitude. Furthermore, the capacity to accept suffering for the sake of goodness, truth and justice is an essential criterion of humanity, because if my own well-being and safety are ultimately more important than truth and justice, then the power of the stronger prevails, then violence and untruth reign supreme...
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?... 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.
