Existential anxiety of doubt drives the person toward the creation of certitude of systems of meaning, which are supported by tradition and authority. Neurotic anxiety builds a narrow castle of certitude which can be defended with the utmost certainty.
Paul TillichEvery person, every place and every action is qualified by this association with the unconditional; it penetrates every moment of daily life and sanctifies it: "The Universe is God's sanctuary. Every work day is a day of the Lord, every supper is a Lord's supper, every work a fulfillment of the divine task, every joy a joy in God. In all preliminary concerns, ultimate concern is present, consecrating them."
