In those who rest on their unshakable faith, pharisaism and fanaticism are the unmistakable symptoms of doubt which has been repressed. Doubt is not overcome by repression but by courage. Courage does not deny that there is doubt, but it takes the doubt into itself as an expression of its own finitude and affirms the content of an ultimate concern. Courage does not need the safety of an unquestionable conviction. It includes the risk without which no creative life is possible.
Paul TillichOne cannot be strong without love. For love is not an irrelevant emotion; it is the blood of life.
Paul TillichWe can speak without voice to the trees and the clouds and the waves of the sea. Without words they respond through the rustling of leaves and the moving of clouds and the murmuring of the sea.
Paul TillichKnowledge of that which concerns us infinitely is possible only in an attitude of infinite concern.
Paul TillichFaith as ultimate concern is an act of the total personality. It happens in the center of the personal life and includes all its elements. Faith is the most centered act of the human mind. It is not a movement of a special section or a special function of man's total being. They all are united in the act of faith.
