The citizens of a city are not guilty of the crimes committed in their city; but they are guilty as participants in the destiny of [humanity] as a whole and in the destiny of their city in particular; for their acts in which freedom was united with destiny have contributed to the destiny in which they participate. They are guilty, not of committing the crimes of which their group is accused, but of contributing to the destiny in which these crimes happened.

Out of the element of participation follows the certainty of faith; out of the element of separation follows the doubt in faith. And each is essential for the nature of faith. Sometimes certainty conquers doubt, but it cannot eliminate doubt. The conquered of today may become the conqueror of tomorrow. Sometimes doubt conquers faith, but it still contains faith. Otherwise it would be indifference.

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.

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

Man is not what he believes himself to be in his conscious decisions.

Every person, every place and every action is qualified by this association with the unconditional; it penetrates every moment of daily life and sanctifies it: "The Universe is God's sanctuary. Every work day is a day of the Lord, every supper is a Lord's supper, every work a fulfillment of the divine task, every joy a joy in God. In all preliminary concerns, ultimate concern is present, consecrating them."

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