Doubt is not the opposite of faith; it is one element of faith. Paul Tillich
Religion is the state of being grasped by an ultimate concern, a concern which qualifies all other concerns as preliminary and which itself contains the answer to the question of a meaning of our life. Paul Tillich
Man is asked to make of himself what he is supposed to become to fulfill his destiny. Paul Tillich
Language... has created the word "loneliness" to express the pain of being alone. And it has created the word "solitude" to express the glory of being alone. Paul Tillich
