Sabbath is not Sunday but "the day of worship". The Bible says he who works on Sabbath should be put to death,

And who wrote the bible? It is just a story. People who have to work on either Sat or Sun,must work and if there is a higher being and I personally do not believe it,then they must forgive people like nurses, doctors,police,firemen,taxi drivers, cemetery workers,any one who takes care of people. If all people for instance worshiped on Sunday, who would staff the hospital where your mother,brother, father, wife or husband was in the ICU. Who would man the emergency rooms when your 3 yr old is burning up with fever,or your new baby had a seizure,would you have them die because you put them to death for not worshiping the way you feel is right?
