Saturday vs. Sunday Sabbath


Why do Jews observe Shabbat from Friday evening to Saturday evening and Christians observe the Sabbath on Sunday? If Christians incorporate Genesis into their Bible as first book of the Old Testament, why is there a discrepancy?



  1. The seven day week has always been the standard method of counting the weeks and the seventh day of the week has always been the Sabbath, see Genesis 1 and the Kuzari. Rabbi Yonatan Eibshitz writes in his book Ya’arat Dvash that one of the reasons that the Christians changed the Sabbath from Saturday to Sunday was because, according to the signs of the various planets Saturday is influenced by the planet Saturn which is associated with depression and pain.
