My theses in case you have been wondering from the first post is that Labor Day and our entire idea of resting outside of the Biblical establishment of true rest is a misguided concept. All excessive holidays and even excessive weekly feasting, can be a detriment to a proper view of the Sabbath.
Bodies need repose as Adam needed rest, but when bodies seek excessive rest outside of Biblical rest, it is akin to sleeping during a night shift in a war zone. It is possible, but highly unlikely to be restful.
The ancient Egyptians and later the French revolutionary calendar tried to modify the Creator’s pattern by establishing a 10-day week only to fail miserably. It is inconceivable that any human invention can alter the certainty of God’s calendar. Labor day or for that matter any day that attempts to undo the eternal plan fails and is intended to suppress the ethics of the Christian week.
