Sabbath day observances had 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 regulations were commanded by God to Israel. (Exodus 35:1-3)
If keeping the sabbath day is still in effect today, then why don't sabbatarians seek to obey ALL that the LORD has commanded? How can someone keep a certain law when they only keep 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.
Now who is going to enforce that? The Jewish synagogue? The Seventh day Adventist church or perhaps the government? Since we do not live under a theocratic state as ancient Israel did under the old covenant of law, no sabbatarian today can live consistently under these Mosaic regulations.
