Change of the Sabbath
From "The True Bible Sabbath", by Ronald Bierer:
"But in vain do they worship me, teaching for doctrines the Commandments of men." Matthew 15:9
How traditions changed the Sabbath
Solon changed the Jewish Sabbath to Saturday over a thousand years after Moses. The True Bible Sabbath, Ronal Bierer, pg. 28.
"Let all the judges and town people, and the occupation of all trades rest on the venerable day of the sun." Edict of March 7, 321 A.D. Corpus Juris Civilis Cod.. lib. 3, tit. 12, Lex. 3. (An edict of Constantine.) [The True Bible Sabbath, pg 25.]
How the Catholic Church changed the Sabbath.
"Had she (the Catholic Church not such power, she could not have done that in which all modern religionists agree with her - she could not have substituted the observance of Sunday, the first day of the week, for the observance of Saturday, the seventh day, a change for which there is no scriptural authority." Doctrinal Catechism, by Stephen Keenan, pg. 174. [The True Bible Sabbath, pg 25.]
"We observe Sunday instead of Saturday because the Catholic Church, in the Council of Laodicea (A.D. 364), transferred the solemnity from Saturday to Sunday." The Convert's Catechism of Catholic Doctrine, pg. 50, 3rd ed. [The True Bible Sabbath, pg 25.]
"You may read the Bible from Genesis to Revelation, and you will not find a single line authorizing the sanctification of Sunday. The Scriptures enforce the religious observance of Saturday, a day which we never sancity." Faith of our fathers, Catholic Cardinal Gibbons, pg. 111. [The True Bible Sabbath, pg 25.]
"The Bible says, 'Remember that thou keep holy the Sabbath day.' The Catholic Church says, No! By my divine power I abolish the Sabbath day, and command you to keep the first day of the week. And lo, the entire civilized world bows down in reverent obedience to the command of the holy Catholic Church!" Father Enright, C.S.S.R. of the Redemptorial College, Kansas City Mo. As taken from History of the Sabbath, pg. 802. [The True Bible Sabbath, pg 26.]
