According to Pastor Vance Stinson of the Church of God International, the Ten Commandments are a "universal" feature of God's Law - meaning that they apply to everyone. Of course, as part of the Decalogue, that would also include the commandment to "remember the Sabbath day and keep it holy." Is that, however, consistent with what Scripture has to say about the Sabbath? OR Does the Bible reveal that the Sabbath was a "cultic" feature of God's Law - meaning that it applied to a relatively small group of people as a religious practice which set them apart from the religious practices of other peoples?
First, although the book of Genesis informs us that the Sabbath was created at the end of God's six days of work after "he" had finished creating (or recreating, as some would say) the earth and universe. Even so, we do not see the Sabbath mentioned again until God introduced it to the children of Israel after "he" had rescued them from Egyptian slavery.
In the sixteenth chapter of the book of Exodus, we read that "the whole congregation of the people of Israel grumbled against Moses and Aaron in the wilderness" because they were hungry (Exodus 16:1-3). As a consequence, we read that God told Moses: "Behold, I am about to rain bread from heaven for you, and the people shall go out and gather a day's portion every day, that I may test them, whether they will walk in my law or not. On the sixth day, when they prepare what they bring in, it will be twice as much as they gather daily." (Exodus 16:4-5, ESV) A little later, in the same chapter, we read: "On the sixth day they gathered twice as much bread, two omers each. And when all the leaders of the congregation came and told Moses, he said to them, 'This is what the Lord has commanded: ‘Tomorrow is a day of solemn rest, a holy Sabbath to the Lord; bake what you will bake and boil what you will boil, and all that is left over lay aside to be kept till the morning.' So they laid it aside till the morning, as Moses commanded them, and it did not stink, and there were no worms in it. Moses said, 'Eat it today, for today is a Sabbath to the Lord; today you will not find it in the field. Six days you shall gather it, but on the seventh day, which is a Sabbath, there will be none.'" (Exodus 16:22-26, ESV) In this way, God introduced the children of Israel to the Sabbath.
Later, at Mount Sinai, we are informed that God included the observance of this Sabbath in the Ten Commandments which "he" gave to Moses (Exodus 20:8-11). Of course, in so doing, the Sabbath became an integral part of God's covenant with the Children of Israel. Indeed, this was made clear at the conclusion of that account of God's dictation to Moses of the terms of the covenant. We read there: "And the Lord said to Moses, 'You are to speak to the people of Israel and say, ‘Above all you shall keep my Sabbaths, for this is a sign between me and you throughout your generations, that you may know that I, the Lord, sanctify you. You shall keep the Sabbath, because it is holy for you. Everyone who profanes it shall be put to death. Whoever does any work on it, that soul shall be cut off from among his people. Six days shall work be done, but the seventh day is a Sabbath of solemn rest, holy to the Lord. Whoever does any work on the Sabbath day shall be put to death. Therefore the people of Israel shall keep the Sabbath, observing the Sabbath throughout their generations, as a covenant forever. It is a sign forever between me and the people of Israel that in six days the Lord made heaven and earth, and on the seventh day he rested and was refreshed.'" (Exodus 31:12-17, ESV)
Thus, we can see that the Sabbath was a special feature of God's covenant with the children of Israel. Certainly, the Gentile nations of the world had no such tradition or practice. Hence, if Mr. Stinson is correct in differentiating between "cultic" and "universal" commandments, then we would have to say that the Sabbath commandment is "cultic"!
