If you follow the Hebrew calendar, the seventh day falls on Saturday.

"Remember the Sabbath day, to keep it holy. Six days you shall labor, and do all your work, but the SEVENTH day is a Sabbath to the LORD your God …Therefore the LORD blessed the Sabbath day and made it holy. "(Exodus 20:8-10a, 11b)

However, the sabbath day was changed by the Roman Emperor Flavius Valerius Constantinus

"On the venerable day of the Sun let the Magistrates and the people residing in the cities rest, and let all workshops be closed."
Edict of Constantine A.D. 321

Sunday was a name given by the heathens to the first day of the week, because it was the day on which they worshipped the sun, Constantine after is nominal conversion to christianity tried to unify christianity and paganism and in the process many pagan cultures were brought in.

The Sabbath is very important but modern Christiandom are ignorant of church history so they undermine the sabbath.

1. Why do you concern yourself with an edict spelled out in God's Constitutional Law given to the people of Isreal in the Land of Canaan when you pretend you are instead a follower of Jesus Christ, God's Constitutional Law in the Kingdom of God — God's special nation of priests?

2. But your modern Christendom was born primarily from the decisions made by the same Constantine and has little to nothing to do with that decreed by God or Jesus Christ, to begin with.(Jesus Christ never proposed a sabbath for His worship or any of that sort.) So, why do you suppose yourself better than the so-called heathens when that which you hold you has more in given with the ideas progressed by heathens and not God Himself?
