Many Christians, particularly those in Evangelical circles would say that Sunday is like the "Christian Sabbath" in which people must come to church and refrain from work. This was seen at Puritan colonies in New England. This eventually evolved to Sunday Laws in the US. The laws forbid working or selling things. To break one of the Sunday Laws would get you stripped of your food allowance for the week on the first offense. On the third offense, the Sunday Laws breaker could be executed. The idea among Christians that the Lord's Day, Sunday, is the Sabbath still has influences on Western society today. There is no school on Sundays, except for Sunday schools. Many stores and restaurants still close early or don't open at all on Sundays. Chick fil A is a good example of a restaurant that closed on Sunday.
What many are unaware of us that the Sabbath is not the Lord's Day nor vice versa. The Sabbath was the last day of the week dedicated to rest from work that God has done with the Earth. And God then transferred that duty to His people as stated in
Exodus 20:11. It is true that Jesus rose from the grave on the first day of the week (
Mark 16:9,
John 20:1, and
Matthew 28:1-7). But we know that God never changes (
Malachi 3:6,
Hebrews 13:8, and
James 1:17). The purpose of the Lord's Day is different from that of the Sabbath. The Lord's Day represents a renewal of creation through His resurrection, just as Sunday is the first day of the new week. The Sabbath also holds significance for Jesus. The Sabbath does not commemorate the resurrection, but rather the day that Jesus's body laid in the tomb between His death and resurruction. This is why some the Orthodox Churches and some Oriental Orthodox Churches acknowledge the Sabbath on Saturday and the Lord's Day in Sunday.
