The meaning of freedom is not exhausted by deliberation, decision, and responsibility, although it must include all this....Free is he who has decided to act in agreement with the spirit beyond all necessities.
Freedom is a challenge and a burden against which man often rebels. He is ready to abandon it, since it is full of contradiction and continually under attack. Freedom can only endure as a vision, and loyalty to it is an act of faith.
There is no freedom without awe. We must cultivate many moments of silence to bring about one moment of expression. We must bear many burdens to have the strength to carry out one act of freedom...Freedom is an act of engagement of the self to the spirit, a spiritual event. Loyalty to freedom means loyalty to the substance of freedom. But such loyalty must be actualized again and again.
--"Religion in a Free Society" (1958)
