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

[A] process was going on in which people were transformed into things, into pieces of reality which pure science can calculate and technical science can control. … [T]he safety which is guaranteed by well-functioning mechanisms for the technical control of nature, by the refined psychological control of the person, by the rapidly increasing organizational control of society – this safety is bought at a high price: man, for whom all this was invented as a means, becomes a means himself in the service of means.

Grace strikes us when we are in great pain and restlessness.

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 basic anxiety, the anxiety of a finite being about the threat of non-being, cannot be eliminated. It belongs to existence itself.

The most intimate motions within the depths of our souls are not completely our own. For they belong also to our friends, to humankind, to the universe, and the Ground of all being, the aim of our life.

Faith embraces itself and the doubt about itself.
