They keep Sunday holy because they received it from the Roman Catholic Church as a legacy of the traditions of men. The Catholic Church teaches that it was by their own authority that they changed the 3rd commandment (actually the 4th) to make Sunday 9the 1st day of the week) the replacement for Saturday (the 7th day). They rightly assert that one may search The Bible from Genesis to Revelation in vain for a scriptural reference that sanctions the transfer of sanctity from the seventh-day Sabbath to Sunday. They ridicule Protestants who claim the Bible as their sole authority for such inconsistency in so following their tradition above the Bible.

Protestants believe that everything in the Word of God (the Bible) is true and it is their only Holy Book.
"Sunday is a Catholic institution, and... can be defended only on Catholic principles... From beginning to end of Scripture there is not a single passage that warrants the transfer of weekly public worship from the last day of the week to the first." Catholic Press, Aug. 25, 1900 "The Sabbath was Saturday, not Sunday. The Church altered the observance of the Sabbath to the observance of Sunday. Protestants must be rather puzzled by the keeping of Sunday when God distinctly said, 'Keep holy the Sabbath Day.' The word Sunday does not come anywhere in the Bible, so, without knowing it they are obeying the authority of the Catholic Church."
