"We rest the designation of Sunday on the church’s having set it apart of its own authority. The seventh-day rest was commanded in the fourth commandment….The selection of Sunday, thus changing the particular day designated in the fourth commandment, was brought about by the gradual concurrence of the early Christian church; and on this basis, and none other, does the Christian Sabbath, the first day of the week, rightly rest."
E.J. Waggoner
But in vain they do worship Me, teaching for doctrines the commandments of men. Matthew 15:9
