"WHICH day is the Sabbath?" asks one. What is written in the law? "The seventh day is the Sabbath of the Lord thy God." "But how," he continues, "do we know that the seventh day of the week is meant?" In several ways, of which we will mention two. The commandment says: "Six days shalt thou labor, and do all thy work; but the seventh day is the Sabbath of the Lord thy God." Now it cannot mean the seventh day of the month or the year, because there are more than seven days in a month or a year. A person can work six days and rest the seventh several times in a single month. Then the commandment must mean the seventh day of some period which contains exactly seven days. And what is that? Every child will answer, "Seven days make one week." A week is the only period of time that contains just seven days, and consequently the seventh day is the last day of the week. Plain enough, is it not? 2. The evangelists all give an account of Christ's crucifixion and resurrection. Speaking of the crucifixion, Luke says: "And that day was the preparation, and the Sabbath drew on." Luke 23:54. It being near the Sabbath, the women did not do any work in connection with the body, but only saw how it was laid. Then "they returned, and prepared spices and ointments; and rested the Sabbath day according to the commandment." Luke 23:56. The next verse says: "Now upon the first day of the week, very early in the morning, they came unto the sepulcher, bringing the spices which they had prepared." Here we see that the Sabbath immediately preceded "the first day of the week." But the week has only seven days; therefore the Sabbath must have been the seventh day of the week. Moreover, this Sabbath day was kept "according to the commandment." Thus the inspired penman gives positive testimony to the fact that the fourth commandment enjoins the observance of the seventh day of the week. And since there has never been another Sabbath commandment, we know that the seventh day of the week, commonly called Saturday, and no other day, is the Sabbath of the Lord.
