The Bible presents the Sabbath as the most ancient institution, excepting marriage, which man was to observe as a moral duty. Genesis 2:1-3. Its existence has run parallel with that of the race. Multitudes of the most intelligent and conscientious believe that its universal observance is necessary if man is to attain to his highest physical, moral, and spiritual development. The most civilized and powerful nations of the earth have even made rigorous laws to enforce a weekly rest-day upon their subjects. It comes to the hundreds of millions of our race every seven days of our mortal life. It furnishes a day of worship and religious instruction to a large portion of the human family. It cannot be denied that it has furnished one of the most powerful impulses that have molded our modern civilization. The importance of the subject, then, cannot be overestimated. ChSa 10.1
