It? There was more than one Sabbath command, including execution of those who worked on the Sabbath. I don't know of anyone who keeps the Sabbath commands, but some sure do try to force it on others.
Even when Sabbatarians today set out to keep the Sabbath day, are they truly "keeping the Sabbath?" To "keep the Sabbath" as it was required under the old covenant would involve
compliance with specific regulations (Exodus 16:23; 35:3; Leviticus 23:32; Jeremiah 17:21) that were
strictly enforced.
If keeping the Sabbath day was still required today, so would the
burnt offerings which went along with them (Leviticus 19:30; 23:2-3; Numbers 28:1-10; 29:39-40; I Chronicles. 23:30-31; II Chronicles 31:2-4; Isaiah 1:13). So
no kindling a fire in any of your dwellings on the sabbath (Exodus 35:3).
Every man must remain in his place on the sabbath (Exodus 16:29).
No trading (Amos 8:5).
No marketing (Nehemiah 10:31; 13:15,19).
These were
commanded by God to Israel (Exodus 35:1). "The
Israelites are to observe the Sabbath, celebrating it for the generations to come as a lasting covenant. It will be a
sign between me and the Israelites forever, for in six days the Lord made the heavens and the earth, and on the seventh day he abstained from work and rested." (Exodus 31:16-17). Moses gives the reason the Sabbath was given to the nation Israel:
“Remember that you were slaves in Egypt and that the Lord your God brought you out of there with a mighty hand and an outstretched arm. Therefore the Lord your God has commanded you to observe the Sabbath day” (Deuteronomy 5:15).
If keeping the Sabbath day is still in affect, then why don't Sabbatarians seek to obey ALL that the LORD has commanded? How can someone keep a certain law when he only keeps part of it? If the Sabbath day laws were still in effect today, then according to Exodus 31:12-18; 35:1-3; and Numbers 15:32-36,
anyone who profaned the Sabbath was put to death and any person who does any work on it, that person shall be cut off from his people. So who is going to enforce that? The Jewish synagogue or perhaps the Seventh day Adventist church? Since we do not live under a theocratic state under the old covenant as ancient Israel did, no Sabbatarian can live consistently under these Mosaic regulations.
