"As regards the Sabbath, or Sunday, there is no necessity for keeping it" (Michelet's Life of Luther, Book IV., chap. ii).
"Paul and the apostles, after the gospel began to be preached and spread over the world, clearly released the people from the observance of the Sabbath" (Luther's Works, Vol. III., p. 73).
"If anywhere the day is made holy for the mere day's sake—if anywhere any one sets up its observance upon a Jewish foundation—then I order you to work on it, to dance on it, to ride on it, to feast on it—to do anything that shall reprove this encroachment on the Christian spirit of liberty" (Table Talk).
MELANCTHON.
"The scripture allows that the observance of the Sabbath has now become void, for it teaches that the Mosaic ceremonies are not needful after the revelation of the gospel" (Augsburg Confession).
"The observance neither of the Sabbath nor of any other day is necessary" (Ibid).
BUCER.
"It is not only a superstition, but an apostasy from Christ, to think that working on the Lord's day, in itself considered, is a sinful thing" (Cox's Sabbath Laws, p. 289).
ZWINGLE.
"It is lawful on the Lord's day, after divine service, for any man to pursue his labors" (Ibid, p. 287).
