Astounding!! Now show me in the Bible where it says "Keep the weekend".I want to know that verse. What day did Jesus keep, if you are a true believer of Christ? Did He keep just any day holy? What was His custom in regards to that? Was He pretty lax in His observance of the commandments?
If the week starts on Monday, and the weekend ends on Sunday, then that makes Sunday the seventh or Sabbath day.
