"The object of theology is what concerns us ultimately. Only those propositions are theological which deal with their object in so far as it can become a matter of ultimate concern for us."

“North American Paul Tillich Society”

“conformism might approximate collectivism, not so much in economic respects, and not too much in political respects, but very much in the pattern of daily life and thought. Whether this will happen or not, and if it does to what degree, is partly dependent on the power of resistance in those who represent the opposite pole of the courage to be, the courage to be as oneself.”

“The existential attitude is one of involvement in contrast to a merely theoretical or detached attitude. “Existential” in this sense can be defined as participating in a situation, especially a cognitive situation, with the whole of one’s existence.”

“In a man like Friedrich von Schlegel the courage to be as an individual self produced complete neglect of participation, but it also produced, in reaction to the emptiness of this self-affirmation, the desire to return to a collective. Schlegel, and with him many extreme individualists in the last hundred years, became Roman Catholics. The courage to be as oneself broke down, and one turned to an institutional embodiment of the courage to be as a part.”

“Man is infinitely concerned about the infinity to which he belongs, from which he is separated, and for which he is longing. Man is totally concerned about the totality which is his true being and which is disrupted in time and space. Man is unconditionally concerned about that which conditions his being beyond all the conditions in him and around him. Man is ultimately concerned about that which determines his ultimate destiny beyond all preliminary necessities and accidents.”

“Without the eros toward truth, theology would not exist.”
