Catholic Record, September 17, 1893 - “Sunday is founded, not of scripture, but on tradition, and is distinctly a Catholic institution. As there is no scripture for the transfer of the day of rest from the last to the first day of the week, Protestants ought to keep their Sabbath on Saturday and thus leave Catholics in full possession of Sunday.”
Ecclesiastical Review, February 1914 - “They [the Protestants] deem it their duty to keep the Sunday holy. Why? Because the Catholic Church tells them to do so. They have no other reason...The observance of Sunday thus comes to be an ecclesiastical law entirely distinct from the divine law of Sabbath observance...The author of the Sunday law...is the Catholic Church.”
Our Sunday Visitor, February 15, 1950 - “Protestants...accept Sunday rather than Saturday as the day for public worship after the Catholic Church made the change...But the Protestant mind does not seem to realize that...In observing the Sunday, they are accepting the authority of the spokesman for the church, the Pope.”
Peter R. Kraemer, Catholic Church Extension Magazine, USA (1975), Chicago, Illinois, “Under the blessing of the Pope Pius XI” - “It is always somewhat laughable, to see the Protestant churches, in pulpit and legislation, demand the observance of Sunday, of which there is nothing in their Bible.”
Pages 3-15 in The Clifton Tract, vol. 4, published by the Roman Catholic Church 1869 - “I am going to propose a very plain and serious question to those who follow ‘the Bible and the Bible only’ to give their most earnest attention. It is this: Why don’t you keep holy the Sabbath day?... “The command of the Almighty God stands clearly written in the Bible in these words: ‘Remember the Sabbath day, to keep it holy. Six days shalt thou labor, and do all thy work; but the seventh day is the Sabbath of the Lord thy God; in it thou shalt not do any work.’ Exodus 20:8-10… “You will answer me, perhaps, that you do keep the Sabbath; for that you abstain from all worldly business and diligently go to church, and say your prayers, and read your Bible at home every Sunday of your lives… “But Sunday is not the Sabbath day. Sunday is the first day of the week: the Sabbath day is the seventh day of the week. Almighty God did not give a commandment that men should keep holy one day in seven; but He named His own day, and said distinctly: ‘Thou shalt keep holy the seventh day’; and He assigned a reason for choosing this day rather than any other - a reason which belongs only to the seventh day of the week, and cannot be applied to the rest. He says, ‘For in six days the Lord made heaven and earth, the sea and all that in them is, and rested on the seventh day: wherefore the Lord blessed the Sabbath day and hallowed it’, Exodus 20:11, Genesis 2:1-3. Almighty God ordered that all men should rest from their labor on the seventh day, because He too had rested on that day: He did not rest on Sunday, but on Saturday. On Sunday, which is the first day of the week, He began the work of creation; He did not finish it. It was on Saturday that He ‘ended His work which he had made: and God blessed the seventh day, and sanctified it: because that in it He had rested from all His work which God created and made.’ Genesis 2:2-3… “Nothing can be more plain and easy to understand than all this; there is nobody who attempts to deny it. It is acknowledged by everybody that the day which Almighty God appointed to be kept holy was Saturday, not Sunday. Why do you then keep holy the Sunday and not Saturday? “You will tell me that Saturday was the Jewish Sabbath, but that the Christian Sabbath has been changed to Sunday. Changed! But by whom? Who has the authority to change an express commandment of Almighty God? When God has spoken and said, ‘Thou shalt keep holy the seventh day’, who shall dare to say, ‘Nay, thou mayest work and do all manner of worldly business on the seventh day: but thou shalt keep holy the first day in its stead?’ This is a most important question, which I know not how you answer… “You are a Protestant, and you profess to go by the Bible and the Bible only; and yet, in so important a manner as the observance of one day in seven as the holy day, you go against the plain letter of the Bible, and put another day in the place of that day which the Bible has commanded. The command to keep holy the seventh day is one of the Ten Commandments; you believe that the other nine are still binding. Who gave you authority to tamper with the fourth? If you are consistent with your own principles, if you really follow the Bible, and the Bible only you ought to be able to produce some portion of the New Testament in which this fourth commandment is expressly altered.” Excerpts from “Why Don’t You Keep Holy the Sabbath Day?”
Stephen Keenan, A Doctrinal Catechism On the Obedience Due to the Church, 3rd edition, Chapter 2, p. 174 (Imprimatur, John Cardinal McCloskey, Archbishop of New York) -
“Question: How prove you that the church had power to command feasts and holydays?
“Answer: By the very act of changing the Sabbath into Sunday, which Protestants allow of and therefore they fondly contradict themselves by keeping Sunday strictly, and breaking most other feasts commanded by the same church.
“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 a 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 of the week, a change for which there is no Scriptural authority.”
James Cardinal Gibbons in the Catholic Mirror, September 23, 1983 - “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...The Protestant World at its birth found the Christian Sabbath too strongly entrenched to run counter to its existence; it was therefore placed under the necessity of acquiescing in the arrangement, thus implying the (Catholic) Church’s right to change the day, for over three hundred years. The Christian Sabbath is therefore to this day, the acknowledged offspring of the Catholic Church as spouse of the Holy Ghost, without a word of remonstrance from the Protestant World.”
The Catholic Universe Bulletin, August 14, 1942, p. 4 - “The (Roman Catholic) Church changed the observance of the Sabbath to Sunday by right of the divine, infallible authority given to her by her founder, Jesus Christ. The Protestant claiming the Bible to be the only guide of faith, has no warrant for observing Sunday.”
