 that this guy worships on Sunday, as do the vast majority of all Protestant folk. They worship on Sunday. Why do you worship on Sunday? In Exodus 20, God said, worship on Saturday. Now, here's the answer, and I'm certain that he doesn't know the answer. He worships on Sunday because the Catholic Church transferred the observance of the commandment to worship on the Sabbath day, Saturday, to worshiping on the first day of the week, Sunday, because that's the day the Lord Jesus Christ rose.
