Labor Day is a US federal holiday observed on the first Monday in September.  The holiday originated in 1882 as the Central Labor Union of New York City sought to create "a day off for the working citizens."  Congress made Labor Day a federal holiday in 1894.  All fifty states have made Labor Day a state holiday.  Today, Labor Day is often regarded as a day of rest. Now we know that the US day of rest is on the first Monday in September. But should Christians observe God's Sabbath day of rest on Saturday or Sunday?  In the Book of Acts, Christians were predominately Jews.  When Gentiles began to receive the gift of salvation through Jesus Christ, they had a problem.  Should they obey the law or the Jewish tradition?  The decision was, "It is my judgment therefore, that we should not make it difficult for the Gentiles who are turning to God.  Instead we should write to them, telling them to abstain from food polluted by idols, from sexual immorality, from the meat of strangled animals and from blood." (Acts 15:19-20) 

A common error in the Sabboth day debate is the concept that the Sabbath was the day of worship.  The Seventh Day Adventists say that God requires the church service to be held on Saturday, which they believe is the Sabbath day.  But that is not what the Sabbath commands.  In Exodus 20:8-11, the Sabbath command was not to do any work on this day.  It doesn't say it has to be the day of worship.  In the Book of Acts, the meetings that were on the Sabbath, were meetings of the Jews and not Christians.  Acts 2:46-47 tells us when Christians had their meetings.  "Every day they continued to meet together in the temple courts.  They broke bread in their homes and ate together with glad and sincere hearts, praising God and enjoying the favor of all the people.  And the Lord added to their number daily those who were being saved."  The day that Christians met on a regular basis was the first day of the week, which was Sunday and not the Sabbath day.  But is there anything wrong with worshipping God on Saturday? No way!  We should worship God everyday, not just Saturday or Sunday.  But the Sabbath is part of the Old Testament Law, and Christians are free from this law.  In Revelation 1:10, Sunday, the Lord's Day, celebrates the New Creation, with Christ as our Resurrected Savior.  We are not required to follow the Sabbath, but are now free to follow Christ.
