IF someone can tell me why people keep Sunday? Is it because Jesus rose on the 1st day of the week? IF so, then why would you need the Lords supper if you have Sunday to replace it. Because he says do this in remembrances of me right?. To me its clear that Sunday keeping is not biblical. What day does this leave for people to come together on then? The Sabbath of course. for Sunday is a lie made by Satan to try and make us forget. Which is why the commandment says Remember. It has been forgotten by most of those who confess to believe in Christ.
