Salvifici Doloris §4

4. This is the origin also of the present reflection, precisely in the Year of the Redemption: a meditation on suffering. Human suffering evokes compassion; it also evokes respect, and in its own way it intimidates. For in suffering is contained the greatness of a specific mystery. This special respect for every form of human suffering must be set at the beginning of what will be expressed here later by the deepest need of the heart, and also by the deep imperative of faith. About the theme of suffering these two reasons seem to draw particularly close to each other and to become one: the need of the heart commands us to overcome fear, and the imperative of faith—formulated, for example, in the words of Saint Paul quoted at the beginning—provides the content, in the name of which and by virtue of which we dare to touch what appears in every man so intangible: for man, in his suffering, remains an intangible mystery.
