a day set aside for rest and worship given in remembrance that God rested from creation on the seventh day or cycle. In early Christianity, the Sabbath was on Saturday, the seventh day, while Sunday became the eighth day of creation, the Lord's Day. This idea came from the resurrection of Jesus, with Sunday now being both the first and the last day.
