Christ has taught man to do good by his suffering and to do good to those who suffer… This is the meaning of suffering, which is truly supernatural and at the same time human. It is supernatural because it is rooted in the divine mystery of the Redemption of the world, and it is likewise deeply human, because in it the person discovers himself, his own humanity, his own dignity, his own mission. We ask precisely you who are weak to become a source of strength for the Church and humanity. In the terrible battle between the forces of good and evil, revealed to our eyes by our modern world, may your suffering in union with the Cross of Christ be victorious!
—POPE JOHN PAUL II, Salvifici Doloros; Apostolic Letter, February 11th, 1984
