Most Christians assume that Sunday is the biblically approved day of worship. The Roman Catholic Church protests that it transferred Christian worship from the biblical Sabbath (Saturday) to Sunday, and that to try to argue that the change was made in the Bible is both dishonest and a denial of Catholic authority. If Protestantism wants to base its teachings only on the Bible, it should worship on Saturday. Over one hundred years ago the Catholic Mirror ran a series of articles discussing the right of the Protestant churches to worship on Sunday. The articles stressed that unless one was willing to accept the authority of the Catholic Church to designate the day of worship, the Christian should observe Saturday. Those articles are presented here in their entirety.
