Abraham Joshua Heschel, The Sabbath
To set apart one day a week for freedom, a day on which we would not use the instruments which have been so easily turned into weapons of destruction, a day for being with ourselves, a day of detachment from the vulgar, of independence of external obligations, a day on which we stop worshipping the idols of technical civilization, a day on which we use no money, a day of armistice in the economic struggle with our fellow men and the forces of nature—is there any institution that holds out a greater hope for man's progress than the Sabbath?
The solution of mankind's most vexing problem will not be found in renouncing technical civilization, but in attaining some degree of independence of it.
Ignatius, Epistle to the Magnesians
"Let us therefore no longer keep the Sabbath after the Jewish manner, and rejoice in days of idleness .... But let every one of you keep the Sabbath after a spiritual manner, rejoicing in meditation on the law, not in relaxation of the body, admiring the workmanship of God, and not eating things prepared the day before, nor using lukewarm drinks, and walking within a prescribed space, nor finding delight in dancing and plaudits which have no sense in them. And after the observance of the Sabbath, let every friend of Christ keep the Lord's [Day, Dominicam] as a festival, the resurrection-day, the queen and chief of all the days.
