Cruelty towards others is always also cruelty towards ourselves.

Faith is the state of being ultimately concerned.

The separation of faith and love is always a consequence of a deterioration of religion.

The courage to be is the courage to accept oneself, in spite of being unacceptable.

Language... has created the word 'loneliness' to express the pain of being alone. And it has created the word 'solitude' to express the glory of being alone.

Theology moves back and forth between two poles, the eternal truth of its foundations and the temporal situation in which the eternal truth must be received.

Why does philosophy use concepts and why does faith use symbols if both try to express the same ultimate? The answer, of course, is that the relation to the ultimate is not the same in each case. The philosophical relation is in principle a detached description of the basic structure in which the ultimate manifests itself. The relation of faith is in principle an involved expression of concern about the meaning of the ultimate for the faithful.
