what in the world do you mean that "Sunday Keeping" is not biblical? How do you keep sunday?
"this is the day that the Lord hath made" the devil has never made a day.....everyday belongs to God!
how is "sunday a lie made by satan?" and if so in Acts 20:7 was Paul being used by the devil to preach to the disciples on the first day of week?
If you believe Act 20:7 is teaching Sunday worship then yes you believe a lie by Satan. They came together everyday to break bread. then you have to make everyday Sunday. So as you can see Sunday worship falls apart. For there is no teaching here about Sunday worship its only a recorded of time not a sign of keeping Sunday.
