One cannot be strong without love. For love is not an irrelevant emotion; it is the blood of life.
Paul TillichThere is faith in every serious doubt, namely, the faith in the truth as such, even if the only truth we can express is our lack of truth.
Paul Tillich...history has shown that the most terrible crimes against love have been committed in the name of fanatically defended doctrines.
Paul TillichOut 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.
