In the courageous standing of uncertainty, faith shows most visibly its dynamic character.
Paul TillichWe are known in a depth of darkness through which we ourselves do not even dare to look. And at the same time, we are seen in a height of a fullness which surpasses our highest vision.
Paul TillichI loved thee beautiful and kind, And plighted an eternal vow; So altered are thy face and mind, t'were perjury to love thee now!
Paul TillichWhy does philosophy use concepts and why does faith use symbols if both try to express the same ultimate? The answer, of course, is that the relation to the ultimate is not the same in each case. The philosophical relation is in principle a detached description of the basic structure in which the ultimate manifests itself. The relation of faith is in principle an involved expression of concern about the meaning of the ultimate for the faithful.
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.
