Remember the sabbath day, to keep it holy
Exodus 20:8-11 Remember the sabbath day, to keep it holy. Six days shalt thou labour, and do all thy work: But the seventh day is the sabbath of the LORD thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates: For in six days the LORD made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the LORD blessed the sabbath day, and hallowed it.
- The Jewish Sabbath is on Saturday, the last day of the week. The day was moved by Emperor Constantine to the first day of the week. This is problematic due to the reasoning that the seventh day is representative of the days in the Genesis story when God rested after making the world. The story didn't involve a creator God resting one day then working six. Changing the day of the week might qualify as not remembering the sabbath day or keeping it holy.
- The Sabbathists and Seventh Day Adventists celebrate the sabbath on Saturday.
In United States Law
- The 4th commandment is not a part of U.S. law or custom. No federal laws are in place to prevent a person from doing any activity on Sunday that they could legally do on any other of the 6 days in the week. There was a time when Blue Laws prevented many things, but most have since been repealed (although a few state or local laws may still limit things like the purchase of alcoholic beverages on Sunday).
