On March 7, 321, however, Roman Emperor Constantine I issued a civil decree making Sunday a day of rest from labor, stating: All judges and city people and the craftsmen shall rest upon the venerable day of the sun. 
QUOTES FROM THE CATHOLIC CHURCH ABOUT THE SABBATH  
Catholic Record (September 1, 1923):  
"Sunday is our mark of authority...The [catholic] Church is above the Bible, and this transference of the  
Sabbath observance is proof of that fact."  
Chancellor Albert Smith for Cardinal of Baltimore Archdiocese, letter dated February 10, 1920:  
"If Protestants would follow the Bible, they should worship God on the Sabbath day [which] by God is  
Saturday. In keeping the Sunday, they are following a law of the Catholic Church."  
The Convert's Catechism of Catholic Doctrine (1957): 50:  
"We observe Sunday instead of Saturday because the Catholic Church transferred the solemnity from  
Saturday to Sunday."  
Our Sunday Visitor (February 5, 195:  
"Practically everything Protestants regard as essential or important they have received from the Catholic  
Church... The Protestant mind does not seem to realize that in accepting the Bible and observing the  
Sunday, in keeping Christmas and Easter, they are accepting the authority of the spokesman for the  
church, the Pope."  
Louis Gaston Segur, Plain Talk about the Protestantism of To-Day (London: Thomas Richardson and  
Son, 1874): 213:  
"Thus the observance of Sunday by the Protestants is a homage they pay, in spite of themselves, to the 
authority of the (Catholic) Church.  
The Catholic Mirror (September 23, 1893):  
"The Catholic Church, for over one thousand years before the existence of a Protestant, by virtue of her  
divine mission, changed the day from Saturday to Sunday..."  
Catholic Priest T. Enright, CSSR, Kansas City, MO:  
"It was the holy Catholic Church that changed the day of rest from Saturday to Sunday, the 1st day of  
the week. And it not only compelled all to keep Sunday, but at the Council of Laodicea, AD 364,  
anathematized those who kept the Sabbath and urged all persons to labor on the 7th day under penalty  
of anathema."  
Catholic Priest T. Enright, CSSR, lecture at Hartford, KS, Feb 18, 1884:  
"I have repeatedly offered $1000 to any one who can furnish any proof from the Bible that Sunday is the  
day we are bound to keep...The Bible says, “Remember the Sabbath day to keep it holy,” but the  
Catholic Church says, “No, keep the first day of the week,” and the whole world bows in obedience."  
Letter from C.F. Thomas, Chancellor of Cardinal Gibbons on October 28, 1895:  
"Of course the Catholic Church claims that the change was her act…And the act is a MARK of her  
ecclesiastical power and authority in religious matters."  
American Catholic Quarterly Review (January 1883):  
"Sunday...is purely a creation of the Catholic Church."
