Morality [or ethics] is not a subject; it is a life put to the test in dozens of moments.

Doubt is the necessary tool of knowledge.

The character of human life, like the character of the human condition, like the character of all life, is "ambiguity": the inseparable mixture of good and evil, the true and false, the creative and destructive forces-both individual and social.

The courage to be is rooted in the God who appears when God has disappeared in the anxiety of doubt.

In the courageous standing of uncertainty, faith shows most visibly its dynamic character.

I hope for the day when everyone can speak again of God without embarrassment.

One cannot be strong without love. For love is not an irrelevant emotion; it is the blood of life.
