The seventh day is the armistice in man’s cruel struggle for existence, a truce in all conflicts, personal and social, peace between man and man, man and nature, peace within man; a day on which handling money is considered a desecration, on which man avows his independence of that which is the world’s chief idol.

A.J. Heschel, The Sabbath, Farrar, Straus and Young, Inc. p 29
