The sabbath is God's special present to the working man, and one of its chief objects is to prolong his life, and preserve efficient his working tone. The savings bank of human existence is the weekly sabbath.- William G. Blaikie

M. Let us now see how far this command has reference to us.
S. In regard to the ceremony [the resting one day in seven], I hold that it was abolished, as the reality existed in Christ.
M. How?
S. Because, by virtue of his death, our old man is crucified, and we are raised up to newness of life.
M. What of the commandment then remains for us?
S. Not to neglect the holy ordinances which contribute to the spiritual polity of the Church; especially to frequent sacred assemblies, to hear the word of God, to celebrate the sacraments, and engage in the regular prayers, as enjoined.
M. But does the figure give us nothing more?
S. Yes, indeed. We must give heed to the thing meant by it; namely, that being engrafted into the body of Christ, and made his members, we cease from our own works, and so resign ourselves to the government of God. -Calvin's Catechism for the Church at Geneva. - on the Fourth Commandment

Sundays, quiet islands on the tossing seas of life. - S.W. Duffield

If anywhere the day is made holy for the mere day's sake -- if anyone set up its observance on a Jewish foundation, then I order you to work on it, to ride on it, to dance on it, to feast on it, to do anything that shall remove this encroachment on Christian liberty.- Luther

Luther, in speaking of the good by itself and the good for its expediency alone, instances the observance of the Christian day of rest, -- a day of repose from manual labour, and of activity in spiritual labour, -- a day of joy and cooperation in the work of Christ's creation. "Keep it holy", says he, "for its use's sake -- both to body and soul! But if anywhere the day is made holy for the mere day's sake, -- if anywhere anyone sets up its observance upon a Jewish foundation, then I order you to work on it, to ride on it, to dance on it, to feast on it -- to do anything that shall reprove this encroachment on the Christian spirit and liberty." - Samuel Tayler Coleridge (1772-1834), Table Talk

Sunday: A day given over by Americans to wishing that they themselves were dead and in Heaven, and that their neighbors were dead and in Hell.- H. L. Mencken

In Hebrew thought the word 'rest ' has a positive meaning and ' stands for consummation of a work accomplished and the joy and satisfaction attendant upon this. Such was its prototype in God...For mankind, too, a great task awaits to be accomplished, and at its close beckons a rest of joy and satisfaction that shall copy the rest of God. Before all other important things, therefore, the Sabbath is an expression of the eschatological principle on which the life of humanity has been constructed...It teaches its lesson through the rhythmical succession of six days of labour and one ensuing day of rest in each successive week. Man is reminded in this way that life is not an aimless existence, that a goal lies beyond.' - Geoffrey B Wilson, Hebrews, Banner of Truth, 1970, p52, quoting, G Vos, Biblical Theology, pp156-157.
