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.

I have given no definition of love. This is impossible, because there is no higher principle by which it could be defined. It is life itself in its actual unity. The forms and structures in which love embodies itself are the forms and structures in which love overcomes its self-destructive forces.

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.

Man and nature belong together in their created glory – in their tragedy and in their salvation.

Fear is the absence of faith.

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

All things and all people, so to speak, call on us with small or loud voices. They want us to listen. They want us to understand their intrinsic claims, their justice of being. But we can give it to them only through the love that listens.
