At first glance, the question “What is the Sabbath day?” seems fairly simple. According to Exodus 20:8–11, the Sabbath is the seventh day of the week, on which the children of Israel were to rest, in remembrance that God created the universe in six days and then “rested” on the seventh day. However, due to the misunderstanding and misinterpretation of some Christian groups, the meaning of the Sabbath day rest has been confused.
