Yes so THIS IS WHAT I'M talking about when I say the Catholic Church changed the Sabbath. Even THEY say they changed it. I don't think anyone has the authority to change God's Word do you? Here are three quotes There are lots of other similar quotes.
Convert’s Catechism of Catholic Doctrine by Reverend Peter Giermann. “Question: Which is the Sabbath day? Answer: Saturday is the Sabbath day. Question: Why do we observe Sunday instead of Saturday? Answer: We observe Sunday instead of Saturday because the Catholic Church in the Council of Laodicea transferred the solemnity from Saturday to Sunday.”
Second, from Reverend Steven Keenan’s Doctrinal Catechism we read this: “Question: Have you any other way of proving that the Church has power to institute festivals of precept? Answer: Had she 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.”
Then from Cardinal Gibbons’ book, The Question Box, p.179, “If the Bible is the only guide for the Christian, then the Seventh-day Adventist is right in observing Saturday with the Jew. Is it not strange that those who make the Bible their only teacher should inconsistently follow in this matter the tradition of the Catholic Church?”
